Last week, a neighbor stopped me in the driveway while I was loading groceries, stressed about whether she could afford a HELOC for her kitchen renovation. She'd been quoted a credit line but had absolutely no idea what her actual monthly payments would look like, or how those payments would change over time. Sound familiar? If you're trying to figure out what a HELOC will actually cost you each month, you're not alone in feeling overwhelmed by all the numbers and terminology. That's exactly why this calculator and guide exist.
A HELOC payment calculator helps you estimate your monthly payments based on your draw amount, interest rate, and repayment schedule. Unlike a traditional mortgage where your payment stays relatively stable, HELOC payments shift dramatically based on which phase you're in. During the draw period (typically 10 years), you might pay only interest on what you've borrowed. But once you hit the repayment period (usually 10-20 years), you're suddenly paying both principal and interest, which can more than double your monthly bill.
Understanding these payment structures before you borrow isn't just smart financial planning. It's about protecting yourself from payment shock down the road and making sure you can comfortably manage the loan throughout its entire life. Think of it like this: you wouldn't sign a lease without knowing the rent, right? Same principle applies here.
A home equity line of credit (HELOC) functions as a revolving credit line secured by your home, similar to how a credit card works but with significantly lower interest rates and your property as collateral. According to the Federal Reserve Bank of St. Louis (2025), U.S. homeowners held approximately $35 trillion in home equity as of the end of 2024, representing a substantial resource that homeowners can potentially access for major expenses.
The textbook answer is that a HELOC lets you borrow against your home's equity up to a predetermined credit limit, drawing funds as needed rather than receiving a lump sum. But really, what makes HELOCs unique is their two-phase structure. You spend years in a draw period where borrowing is flexible and payments are manageable, then transition into a repayment period where the financial obligations intensify considerably.
According to Curinos market data (October 2025), the average HELOC interest rate stood at 7.75% as of late October 2025, with rates for highly qualified borrowers potentially lower. This represents a decline from peaks above 10% in previous years, driven in part by the Federal Reserve's rate-cutting campaign that began in late 2024.
Let me break down the key differences because these products often get confused. A home equity loan gives you a fixed lump sum with a fixed interest rate and fixed monthly payments over a set term, typically 5-30 years. You know exactly what you're getting and what you'll pay from day one. It's predictable and structured.
A HELOC, on the other hand, operates as a revolving line of credit with a variable interest rate tied to the prime rate. You can draw funds multiple times up to your credit limit during the draw period, pay them back, and draw again if needed. Your monthly payment fluctuates based on how much you've borrowed and what the interest rate is doing.
Think about it this way. If you're renovating your home room by room over several years, a HELOC's flexibility lets you take out exactly what you need when you need it. You're only paying interest on the actual balance you've drawn, not the entire credit line. That flexibility comes with less predictability in your monthly payments, though, especially when interest rates change.
Here's where HELOCs get interesting and where many borrowers don't fully understand what they're signing up for. Every HELOC has two distinct phases: the draw period and the repayment period.
During the draw period, you can access your credit line whenever you need funds, up to your approved limit. Most lenders only require interest-only payments during this phase, though you're usually allowed to pay down principal if you choose. This is when HELOC payments feel manageable and attractive.
Let's say you have a $50,000 credit line at 7.75% (the market average as of late October 2025) and you've drawn $30,000. Your monthly interest-only payment would be approximately $194. That's considerably lower than if you were paying principal and interest from the start.
But here's what nobody tells you up front. That $194 monthly payment is temporary. It's designed to give you breathing room while you're actively using the credit line, but it's not the long-term reality of what this loan will cost.
Once the draw period ends, everything changes. You can no longer draw additional funds, and you must start paying back both the principal and the interest you owe. This is when that $194 monthly payment could jump to $400 or more, depending on your balance and the repayment term.
According to CBS News analysis (October 2025), a $50,000 HELOC balance with a 10-year repayment period at current rates would cost approximately $604 per month, while a 15-year repayment period would cost around $475 per month. Compare that to the interest-only payments you were making during the draw period, and you can see why so many borrowers experience payment shock.
This transition catches a lot of people off guard. When we acquired our processing system at AmeriSave, we saw borrower concerns about this phase transition come up repeatedly in customer service data. People thought they understood their HELOC terms, but they didn't truly grasp how much their monthly obligation would increase once repayment kicked in.
The HELOC market in 2025 looks dramatically different than it did even two years ago. After the Federal Reserve raised rates aggressively from 2022 through mid-2024 to combat inflation, HELOC rates peaked above 10% for many borrowers. Since September 2024, however, the Fed has begun cutting rates again, with two quarter-point reductions in late 2024 and two more in 2025 as of early November.
According to The Wall Street Journal prime rate tracking data (November 2025), the prime rate (to which most HELOCs are tied) currently sits at 7.00% following the Federal Reserve's October 2025 rate cut. Individual HELOC rates vary based on the prime rate plus a margin determined by the lender, your credit score, your loan-to-value ratio, and other factors.
Here's what's driving increased HELOC interest in 2025. Homeowners who refinanced or purchased homes when rates were at historic lows between 2020 and 2022 are sitting on mortgages with interest rates between 2.5% and 4%. They don't want to give up those rates by doing a cash-out refinance where they'd be replacing their entire mortgage at today's 6-7% rates. Instead, they're keeping their low-rate first mortgage intact and using a HELOC as a second mortgage to access cash when needed.
The math makes sense. Let's say you have a $300,000 first mortgage at 3.5% and you need $50,000 for home improvements. You could do a cash-out refinance and end up with a $350,000 mortgage at 6.75%, significantly increasing your monthly payment on the entire balance. Or you could keep your 3.5% first mortgage and take out a $50,000 HELOC at around 8%, paying the higher rate only on the additional borrowing.
According to Cotality data (September 2025), homeowners with mortgages held a collective $17.5 trillion in home equity in the second quarter of 2025, with the average mortgage holder having approximately $307,000 in equity. Of that equity, approximately $195,000 per homeowner is considered "tappable" (equity that can be accessed while maintaining at least 20% ownership stake in the home).
HELOCs almost universally come with variable interest rates, which means your rate and monthly payment can change periodically based on market conditions. Most HELOCs are tied to the prime rate, which itself moves in response to Federal Reserve policy changes.
The way it works is straightforward. Your HELOC rate equals the prime rate plus a margin set by your lender. That margin typically ranges from 0% to 2% depending on your creditworthiness and the loan terms. So if the prime rate is 7.00% and your margin is 0.50%, your HELOC rate is 7.50%.
When the Federal Reserve cuts its benchmark rate (as it did in September and October 2024, and again twice in 2025), the prime rate usually drops by the same amount within a day or two. Your HELOC rate then adjusts at your next rate adjustment date, which could be monthly, quarterly, or semi-annually depending on your loan terms.
That responsiveness cuts both ways. When rates fall, your HELOC becomes cheaper automatically without refinancing. But when rates rise, your monthly payment increases even if you haven't borrowed any additional funds. This is fundamentally different from a fixed-rate home equity loan where your rate stays the same for the life of the loan.
Most HELOCs include rate caps that limit how much your interest rate can increase. A lifetime cap (often around 18%) prevents your rate from climbing above a certain threshold even if the prime rate soars. Some HELOCs also include periodic adjustment caps that limit how much the rate can change in a single adjustment period.
Let me walk you through exactly how HELOC payments function because this is where most of the confusion happens. The payment calculation methods are totally different depending on whether you're in the draw period or the repayment period.
During the draw period, most lenders offer interest-only payment options, though they'll allow you to pay down principal if you choose. Your monthly payment is calculated by taking your current balance, multiplying it by your annual interest rate, and dividing by 12.
Here's a real example using market rates from October 2025. According to Curinos data, average HELOC rates for qualified borrowers were around 7.75%. Let's say you've drawn $40,000 from your credit line.
Monthly Interest = ($40,000 × 0.0775) ÷ 12 = $258
That $258 monthly payment covers only the interest that accrued that month. None of it goes toward paying down your $40,000 balance. You're essentially treading water, keeping the loan from growing but not making progress on paying it off.
Now here's where the flexibility comes in. If you choose to make additional principal payments during the draw period, you reduce your balance and therefore lower your monthly interest charges. If you pay off the entire balance, your monthly payment drops to zero until you draw again. This is what makes HELOCs attractive for managing cash flow during long-term projects or when you have irregular income.
But I'm going to be straight with you. Most borrowers stick to the minimum interest-only payments during the draw period. They're using the funds for a purpose (home renovation, debt consolidation, education expenses) and don't have extra cash lying around to pay down principal ahead of schedule. That means they hit the end of the 10-year draw period with most or all of their balance still outstanding.
Once you enter the repayment period, the payment calculation changes completely. You're now required to pay both principal and interest over the remaining loan term, typically 10-20 years.
The formula gets more complex because we're now calculating an amortized loan payment. Your payment is calculated to fully pay off your balance by the end of the repayment term, with each payment covering that month's interest plus a portion of the principal.
Using the same $40,000 balance at 7.75% with a 10-year repayment period:
Monthly Payment = $40,000 × [0.0775/12 × (1 + 0.0775/12)^120] ÷ [(1 + 0.0775/12)^120 - 1] = approximately $481
That's almost twice what you were paying during the interest-only draw period.
If you opt for a longer 15-year repayment period, the payment drops to approximately $379 per month. The trade-off is you'll pay significantly more in total interest over the life of the loan.
Your HELOC payment can change for two distinct reasons: changes in your interest rate or changes in your loan phase (moving from draw to repayment).
Rate adjustments typically happen monthly, quarterly, or annually depending on your loan terms. At AmeriSave, we structure our HELOCs with monthly rate adjustments to ensure borrowers always have access to the current market rate, which has been particularly beneficial as rates have been declining recently.
When your rate adjusts, your lender recalculates your payment based on your current balance, the new interest rate, and the remaining term. If you're in the draw period with interest-only payments, a 0.25% rate decrease on a $50,000 balance would lower your monthly payment by about $10. During the repayment period, that same rate decrease would save you closer to $15-20 per month depending on your remaining term.
The phase transition from draw to repayment is a one-time event that happens at a predetermined date (typically 10 years after you opened the HELOC). This adjustment is usually much more dramatic than normal rate fluctuations because you're switching from interest-only to principal-and-interest payments.
The choice between interest-only and principal-and-interest payments (when available) represents a fundamental trade-off between short-term cash flow and long-term financial efficiency.
Interest-only payments keep your monthly obligations low but don't build equity or reduce your debt. You're essentially renting your own home equity rather than reclaiming it. Over a 10-year draw period paying interest-only on a $50,000 balance at 7.75%, you'd pay approximately $38,750 in interest while still owing the full $50,000.
Principal-and-interest payments from the start cost more monthly but steadily reduce your balance and total interest paid. Using the same $50,000 at 7.75% over a full 20-year term (no separate draw period), you'd pay approximately $413 per month and $49,120 in total interest. You'd also completely own that equity again after 20 years instead of still owing $50,000 after 10 years of interest-only payments.
I'm in my MSW program right now learning about financial decision-making and stress, and this choice between immediate affordability and long-term cost comes up constantly. There's no universally right answer because people's circumstances differ dramatically. A family scraping together funds for an emergency medical expense needs the lower interest-only payment right now. A homeowner with stable income using a HELOC strategically for home improvements that add value might benefit from paying down principal during the draw period.
What matters most is understanding the real cost of each choice and making it deliberately rather than defaulting to the minimum payment without considering the implications.
A HELOC payment calculator takes the guesswork out of figuring out what you'll actually pay each month, both during the draw period and after you transition to repayment. Let me walk you through how to use one effectively.
To get accurate payment estimates, you'll need several key pieces of information.
Credit Line Amount: This is the maximum you're approved to borrow, which is typically based on your available equity. Most lenders will lend up to 80-85% of your home's value minus your existing mortgage balance. If your home is worth $400,000 and you owe $240,000, you'd have $160,000 in equity. At 80% combined loan-to-value (CLTV), you could access up to $80,000 ($400,000 × 0.80 = $320,000 total borrowing capacity minus your $240,000 first mortgage).
Draw Amount: This is how much you actually plan to borrow from your credit line initially or at various points. You don't have to use your entire credit line. If you're approved for $80,000 but only need $50,000 for your current project, that's your draw amount for calculation purposes.
Interest Rate: You'll need your actual HELOC interest rate, which should be disclosed in your loan estimate or offer documents. If you're still shopping, use market averages (around 7.75-8.00% as of late 2025 for qualified borrowers) or get quotes from multiple lenders. Remember that your rate equals the prime rate plus your lender's margin.
Draw Period Length: Most HELOCs have a 10-year draw period, though some lenders offer 5, 7, or 15-year options. This affects how long you can access funds and make interest-only payments.
Repayment Period Length: Typically 10-20 years after the draw period ends, though terms vary by lender. A 10-year repayment means higher monthly payments but less total interest paid. A 20-year repayment means lower monthly payments but more interest over time.
Payment Type During Draw: Are you planning to make interest-only payments or pay down principal during the draw period? This dramatically affects your balance when repayment begins.
When you run the numbers through a HELOC calculator, you'll typically see several outputs.
Draw Period Payment: This shows your monthly payment during the initial phase, usually interest-only unless you've specified otherwise. On a $50,000 draw at 7.75%, you'd see approximately $323 per month.
Repayment Period Payment: This shows what your payment jumps to once the draw period ends and you must start paying back principal. That same $50,000 at 7.75% would become approximately $600 per month over a 10-year repayment period or $472 per month over 15 years.
Total Interest Paid: This shows the cumulative interest you'll pay over the entire life of the HELOC if you keep the balance through the full term. For our $50,000 example, you'd pay approximately $71,480 in total interest over the full 20-year period (10-year draw with interest-only payments plus 10-year repayment).
Monthly Payment Schedule: Better calculators show you how your payment changes over time, especially when the draw period ends. This visualization helps you prepare for the payment increase that's coming.
Rate Change Scenarios: Some calculators let you model what happens if interest rates rise or fall by 0.5%, 1%, or 2%. Given that HELOCs have variable rates, this feature helps you understand your payment risk if the Federal Reserve changes course and starts raising rates again.
HELOC calculators make several assumptions that may not match your actual situation:
Most calculators assume you draw the full amount immediately and maintain that balance throughout the draw period. In reality, many borrowers draw funds gradually over time or draw, repay, and draw again. Your actual payments might be lower if you don't use the full credit line right away.
Calculators typically use a fixed interest rate for the projection, even though your actual HELOC rate will fluctuate. If rates rise during your loan term, your actual payments will be higher than projected. If rates fall (as they've been doing recently), your payments will be lower.
Many calculators assume interest-only payments during the draw period, which means you'll owe the full balance when repayment begins. If you pay down principal during the draw period, your repayment phase payment will be lower than the calculator shows.
Tax implications aren't included in most calculators. Under current law (2017 Tax Cuts and Jobs Act), HELOC interest is only tax-deductible if you use the funds to buy, build, or substantially improve the home that secures the loan. The deduction is also limited to interest on up to $750,000 of total mortgage debt ($375,000 if married filing separately). If you're using HELOC funds for debt consolidation or other purposes, the interest isn't deductible.
The real power of a HELOC calculator comes from running multiple scenarios to see how different choices affect your bottom line.
Compare what happens if you make interest-only payments during the draw period versus paying an extra $100-200 monthly toward principal. Using a $60,000 HELOC at 7.75%:
That extra $200 monthly during the draw period saves you almost $288 monthly during repayment and thousands in total interest.
See how repayment term affects your monthly payment and total cost. Same $60,000 balance at 7.75%:
The 20-year term costs you more than twice the interest of the 10-year term, but it keeps your monthly payment nearly $223 lower.
Model what happens if you're approved for $75,000 but only draw $50,000. Your monthly payments are based solely on what you actually borrow, not your approved limit:
Using only what you need saves you $161 per month in interest costs during the draw period.
Your monthly HELOC payment isn't determined by a single factor. It's influenced by several interconnected variables, some within your control and others tied to broader economic conditions.
The amount you can borrow through a HELOC depends primarily on how much equity you've built in your home. Lenders use the combined loan-to-value (CLTV) ratio to determine your maximum credit line.
CLTV is calculated by adding your existing mortgage balance plus your potential HELOC amount and dividing by your home's current market value. Most lenders cap CLTV at 80-85%, though some go up to 90% for exceptionally qualified borrowers.
Here's how this works in practice. Let's say you own a home valued at $500,000 with a remaining mortgage balance of $350,000. That gives you $150,000 in equity, which is 30% of your home's value.
A lender using an 80% CLTV limit would calculate:
Maximum Total Borrowing = $500,000 × 0.80 = $400,000
Available HELOC = $400,000 - $350,000 = $50,000
But here's what's interesting. If your home appraises higher than you expected, you might qualify for more. Home values in many markets have increased substantially over the past few years. According to the Federal Reserve Bank of St. Louis (2025), homeowners collectively held approximately $35 trillion in home equity as of the end of 2024, representing historic highs.
Your LTV ratio also affects your interest rate. Borrowers with lower CLTV ratios (more equity) typically receive better rates because they represent less risk to the lender. A borrower at 65% CLTV might get a rate 0.25-0.50% lower than someone at 80% CLTV, even with identical credit scores.
Your credit score plays a significant role in determining your HELOC interest rate, which directly affects your monthly payment. Lenders add a margin to the prime rate, and that margin is heavily influenced by your creditworthiness.
According to industry standards, borrowers with credit scores above 740 typically receive the best rates, often prime rate plus 0-0.5%. Those with scores between 680-739 might see margins of 0.5-1.5%. Borrowers with scores below 680 face margins of 1.5% or higher, if they qualify at all.
Let's look at the real dollar impact. Using a $50,000 HELOC with a current prime rate of 7.00%:
That 1.25% rate difference between excellent and fair credit costs an extra $52 monthly, or $624 annually, just on interest during the draw period. Over a 20-year HELOC term, it could mean paying thousands of dollars more.
This is one area where you have control before you apply. If your credit score is borderline, taking a few months to pay down credit cards and fix any errors on your credit report can save you significant money. When I was working in underwriting before my current role, we saw borrowers improve their offers substantially by raising their scores just 20-30 points.
HELOC rates are directly tied to the prime rate, which moves in lockstep with the Federal Reserve's monetary policy. Understanding this connection helps you anticipate how your payment might change in the future.
The prime rate is a benchmark rate that banks charge their most creditworthy customers. It typically runs 3 percentage points above the Federal Funds rate, which is the rate the Federal Reserve controls. According to The Wall Street Journal prime rate data (November 2025), the prime rate currently stands at 7.00% following the Federal Reserve's October 2025 rate cut.
When the Fed announces a 0.25% (25 basis points) rate cut, here's what happens:
Let's quantify this impact. On a $60,000 HELOC balance:
Two quarter-point Fed cuts save you $25 monthly, or $300 annually, without any action on your part.
refinanceThe flip side is equally true. If inflation rebounds and the Fed starts raising rates again, your HELOC payment increases automatically. This is why some borrowers choose totheir HELOC into a fixed-rate home equity loan once rates hit a level they're comfortable with, locking in predictability at the cost of some flexibility.
The length of your draw period affects both your monthly payment flexibility and your long-term costs. While 10 years is most common, some lenders offer 5-year or 15-year draw periods.
A shorter draw period means you transition to full principal-and-interest payments sooner, which increases your monthly payment earlier but reduces total interest paid. A longer draw period extends the time you can make interest-only payments, keeping monthly costs lower for longer but potentially increasing total interest costs if you don't voluntarily pay down principal.
Let's compare a $50,000 HELOC at 7.75% with different draw period lengths.
The 15-year draw period keeps payments lowest for longest but results in a brutal payment shock when repayment kicks in and costs about $20,460 more in total interest than the 5-year draw option.
At AmeriSave, we typically recommend 10-year draw periods as the sweet spot for most borrowers. It gives you substantial time to use the credit line flexibly while not pushing the repayment burden so far into the future that you end up with an unsustainable payment increase.
Once your draw period ends, the length of your repayment period determines your monthly principal-and-interest payment. Most lenders offer 10-year, 15-year, or 20-year repayment periods, and this choice involves a classic trade-off between monthly affordability and total interest cost.
Using a $75,000 balance at 7.75% after a 10-year interest-only draw period.
The 20-year repayment period costs $278 less monthly than the 10-year option but you'll pay $41,280 more in interest over the loan's life. That's more than half the original loan amount paid in additional interest charges.
There's also a timing consideration. A 10-year repayment after a 10-year draw means your HELOC is completely paid off 20 years after you opened it. Many borrowers find this attractive because it aligns with major life goals, maybe paying off the HELOC around the same time your kids finish college or you're thinking about retirement.
A 20-year repayment after a 10-year draw means you're carrying this debt for 30 years total, potentially well into retirement for older borrowers. That extended obligation can complicate financial planning and retirement budgeting.
HELOC costs extend beyond just interest payments. Various fees can affect both your upfront costs and ongoing monthly obligations.
Application and Origination Fees: Some lenders charge $0-500 to process your HELOC application. These are typically one-time costs paid at closing. At AmeriSave, we structure our pricing to minimize upfront fees while remaining competitive on interest rates.
Appraisal Fees: Most lenders require a professional appraisal to verify your home's current value, typically costing $300-600 depending on your property type and location. Some lenders offer automated valuation models (AVMs) or waive appraisals for customers with sufficient equity and recent appraisals.
Annual Fees: Some HELOCs charge an annual maintenance fee of $50-100 to keep the credit line open, even if you're not using it. This matters particularly if you plan to keep a HELOC available for emergencies but may not draw from it frequently.
Transaction Fees: A few lenders charge fees each time you draw funds, typically $25-50 per transaction. These can add up if you're drawing smaller amounts multiple times. Most major lenders, including AmeriSave, don't charge per-transaction fees.
Early Closure Fees: If you close your HELOC within the first 2-3 years, some lenders charge an early termination or prepayment penalty, typically $300-500. This is to recoup their upfront costs if you don't keep the line open for a minimum period.
Rate Lock or Fixed-Rate Options: Some HELOCs offer the ability to convert all or part of your balance to a fixed rate, protecting you from future rate increases. This option typically comes with a slightly higher rate than the variable rate, perhaps 0.5-1% higher.
Here's what this looks like in real numbers. On a $60,000 HELOC over 20 years:
Without annual fee: $323/month during draw
With $75 annual fee: $323/month + $6.25/month = $329.25/month
The fee adds about 2% to your effective cost, which might seem minor but compounds over 20 years to an extra $1,500 in fees alone.
Let me walk you through the actual math for calculating HELOC payments, both for the draw period and the repayment period. Understanding these calculations helps you verify that your lender's numbers are accurate and lets you plan your finances more precisely.
During the draw period when you're making interest-only payments, the calculation is straightforward. You're paying only the interest that accrues each month on your outstanding balance.
Let's work through a specific example. You have a HELOC with a $45,000 current balance and an interest rate of 7.75%.
Step 1: Convert percentage to decimal
7.75% = 0.0775
Step 2: Calculate annual interest
$45,000 × 0.0775 = $3,488
Step 3: Divide by 12 for monthly payment
$3,488 ÷ 12 = $291
Your monthly interest-only payment is $291.
Now here's what's important. If your balance changes, your payment changes proportionally. If you pay down $5,000 of principal, dropping your balance to $40,000:
$40,000 × 0.0775 ÷ 12 = $258
Your payment drops to $258 immediately. This is the flexibility of a HELOC during the draw period.
Similarly, if interest rates change, your payment adjusts. If rates drop 0.25% to 7.50%:
$45,000 × 0.0750 ÷ 12 = $281
Your payment decreases to $281, saving you $10 monthly without any action required.
Once you enter the repayment period, calculating your payment gets more complex because you're amortizing the loan over a fixed term. The formula accounts for both the principal you need to repay and the interest that accrues over time.
Formula:
Monthly Payment = P × [r(1+r)^n] ÷ [(1+r)^n - 1]
Where:
Let's calculate the repayment period payment for a $50,000 balance at 7.75% over a 10-year repayment term (120 months).
Step 1: Convert annual rate to monthly decimal
7.75% ÷ 12 = 0.6458% = 0.006458
Step 2: Calculate (1+r)^n
(1 + 0.006458)^120 = 2.1654
Step 3: Calculate numerator
$50,000 × [0.006458 × 2.1654] = $699.42
Step 4: Calculate denominator
2.1654 - 1 = 1.1654
Step 5: Divide numerator by denominator
$699.42 ÷ 1.1654 = $600
Your monthly principal-and-interest payment is $600.
Compare this to your interest-only payment during the draw period: $50,000 × 0.0775 ÷ 12 = $323
That's a $277 monthly increase when you transition from draw to repayment. Over 12 months, that's $3,324 more you need to budget annually.
If you extend the repayment period to 15 years (180 months) instead:
(1 + 0.006458)^180 = 3.1311 $50,000 × [0.006458 × 3.1311] ÷ [3.1311 - 1] = $1,011.86 ÷ 2.1311 = $475
The longer term reduces your monthly payment by $125, but you'll be paying that $475 for five additional years, resulting in significantly more total interest.
With a variable-rate HELOC, your interest rate and payment recalculate periodically based on changes in the prime rate. Let me show you how rate changes affect your payments in both the draw and repayment periods.
Original payment at 7.75% on $55,000: $55,000 × 0.0775 ÷ 12 = $355
After 0.25% rate increase to 8.00%:
$55,000 × 0.0800 ÷ 12 = $367
After another 0.25% increase to 8.25%: $55,000 × 0.0825 ÷ 12 = $378
Each 0.25% rate increase costs you about $12 more per month on a $55,000 balance. That's $144 more annually. If rates increase 1% total over a year, you're paying an extra $550 annually without borrowing anything additional.
This gets more complicated because your principal balance is decreasing each month. The lender recalculates your payment using your remaining balance, new interest rate, and remaining term.
Let's say you're 3 years into a 10-year repayment period. Your original balance was $55,000 at 7.75%. You've paid it down to $39,432 with 84 months remaining. Then rates rise 0.5% to 8.25%.
New payment calculation: r = 0.0825 ÷ 12 = 0.006875 n = 84 months (1.006875)^84 = 1.7650
Payment = $39,432 × [0.006875 × 1.7650] ÷ [1.7650 - 1] Payment = $478.74 ÷ 0.7650 = $626
Your payment increased from approximately $606 to $626, even though your balance has dropped substantially. This is the risk of variable-rate debt during rising-rate environments.
The reverse is also true. When the Federal Reserve cuts rates, your payment drops even as you continue paying down principal. This has been the experience for HELOC borrowers in late 2024 and 2025 as rates have fallen from peaks above 10% to current levels around 7.75%.
Let me provide several complete scenarios showing how HELOC payments work from opening through final payoff.
Years 1-10 (Draw Period, Interest-Only): Monthly payment: $30,000 × 0.0775 ÷ 12 = $194 Total paid: $194 × 120 = $23,280 Remaining balance: $30,000
Years 11-20 (Repayment Period):
Monthly payment: $360 (calculated using amortization formula) Total paid: $360 × 120 = $43,200 Remaining balance: $0
Total interest paid over 20 years: $36,480
Years 1-10 (Draw Period, Interest-Only Plus $200 Extra Monthly)
Monthly payment: $75,000 × 0.0775 ÷ 12 = $484 interest + $200 principal = $684
Balance reduction over 10 years: $200 × 120 = $24,000
Remaining balance after draw period: $51,000
Years 11-20 (Repayment Period on $51,000):
Monthly payment: $612
Total paid: $612 × 120 = $73,440
Total interest paid: approximately $48,440 vs. $66,080 if no extra principal paid during draw
The extra $200 monthly during the draw period ($24,000 total) saved approximately $17,640 in interest and reduced the repayment period payment by about $188.
Year 1 at 7.75%: $646/month
Year 2 at 8.25% (0.5% increase): $688/month
Year 3 at 7.25% (1% decrease): $604/month
Year 4 at 7.75% (0.5% increase): $646/month
Over these 4 years, your payment fluctuated $84 monthly ($1,008 annually) based purely on rate changes, without any change in your $100,000 balance.
Not everyone uses a HELOC the same way. Your optimal payment strategy depends on why you're borrowing, your financial situation, and your long-term goals. Let me walk you through several common scenarios.
HELOCs are popular for home renovations because you can draw funds as different phases of the project are completed rather than taking a lump sum upfront.
The smart approach here is to draw only what you need for each phase and, if possible, pay back at least some principal before drawing again for the next phase. This keeps your average balance lower and minimizes interest charges.
Let's say you're doing a $60,000 kitchen renovation in three phases over 12 months:
Phase 1 (Months 1-4): Draw $20,000 for demolition and rough-in Interest-only at 7.75%: $129/month
Phase 2 (Months 5-8): Draw additional $25,000 for cabinets and appliances
Balance now $45,000, Interest-only: $291/month
Phase 3 (Months 9-12): Draw final $15,000 for finishing work Final balance $60,000, Interest-only: $388/month
Average monthly payment during the 12-month project: $269
If you had drawn the full $60,000 upfront, you'd have paid $388 monthly from day one, costing an extra $1,428 in interest during the construction period.
For home renovations, there's also a tax consideration. According to the IRS, HELOC interest is deductible when the funds are used to buy, build, or substantially improve the home securing the loan. Keep detailed records of how you spend the funds and the improvements made, as you'll need this documentation if you itemize deductions.
Some homeowners accelerate principal payments once the renovation is complete, and they've stabilized their cash flow. If you were paying $388 monthly in interest and you add $400 in principal payments, you'd reduce your $60,000 balance to $0 in about 11 years while still in the draw period, avoiding the payment spike when repayment kicks in.
Using a HELOC to consolidate high-interest debt can save substantial money, but it requires discipline to avoid running up new debt.
Let's look at the math. You have:
You take out a $25,000 HELOC at 7.75% to pay off both debts:
Over the 10-year draw period, you'd save $40,320 in payments if you stuck to interest-only. However, and this is crucial, you'd still owe $25,000 after 10 years instead of having your debts paid off.
The right strategy is to take that $336 monthly savings and apply it toward HELOC principal:
Compare this to keeping the original debts:
The HELOC consolidation saves you about $14,100 in interest and eliminates the debt 4+ years sooner, but only if you maintain the same payment level rather than dropping to the lower minimum.
The risk is that many people consolidate debt, enjoy the lower payment, but then accumulate new credit card balances. Now they have the HELOC plus new credit card debt, worse off than before. I've seen this pattern in our customer data at AmeriSave, and it's heartbreaking because the HELOC was meant to be a solution but became an additional burden.
Some homeowners maintain a HELOC as an emergency fund alternative, keeping the credit line open but unused until needed.
This strategy works best with lenders that charge no annual fees or low annual fees. You're essentially paying $0-100 yearly for access to tens of thousands of dollars in emergency funds if needed.
The advantages over a traditional emergency fund are:
The disadvantages are:
If you go this route, I'd recommend:
For example, your air conditioning system dies, requiring a $8,000 replacement. Instead of draining your entire emergency fund or charging it to a credit card at 20%+, you draw $8,000 from your HELOC at 7.75%:
Monthly interest-only: $52 If paid off over 24 months: $359/month, $703 total interest
Much more manageable than the alternative options while preserving your cash savings.
Using a HELOC on your primary residence to purchase investment property or a second home is a strategy that can work well but comes with additional risks.
The math can be attractive. Let's say you want to buy a $150,000 rental property with 25% down ($37,500). Instead of saving for years, you could:
Draw $37,500 from your HELOC at 7.75%: $242/month interest-only
Rental income after expenses: $800/month
Net monthly cash flow: $558
You've acquired the rental property with minimal cash outlay, and the property generates enough income to cover the HELOC payment plus provide additional cash flow.
The strategy works if:
The strategy fails if any of those conditions aren't met. If your tenant moves out and you go 3-4 months with no rental income, you're still responsible for the $242 HELOC payment plus the rental property's mortgage, taxes, and insurance. The risk is you're now supporting two properties with your income.
For a second home (vacation property), the calculation is different because there's no rental income. You're paying the HELOC interest plus the second home's costs purely from your income. Make sure you can comfortably afford both before drawing the funds.
Also note that HELOC interest used for investment property purchases is deductible as investment interest (subject to limitations) rather than mortgage interest, which has different tax treatment. Consult a tax professional to understand the implications for your specific situation.
HELOCs can provide funding for major medical expenses or education costs, but these uses deserve special consideration because the money isn't going toward an appreciating asset.
For medical expenses, a HELOC might make sense when:
The interest rate advantage is clear. Medical payment plans often charge 10-15% or more, while HELOCs average under 8%. On $30,000 in medical debt:
Medical payment plan at 12%: $334/month over 10 years HELOC at 7.75%: $194/month interest-only, or $360/month over 10-year repayment
You'll save about $156 monthly initially, though you need to transition to paying principal to actually eliminate the debt.
For education costs, the analysis is more complex. Federal student loans offer protections that HELOCs don't: income-driven repayment plans, forbearance options, potential forgiveness programs. Private student loans typically range from 7-14% depending on credit, while HELOCs are currently around 7.75%.
If you're considering a HELOC for education:
I'm torn on this use case personally. As someone pursuing my MSW degree, I understand the cost of education and the desire to minimize debt. But using your home equity for education means the education had better provide a return. If the degree doesn't lead to increased earnings, you've put your housing at risk.
A HELOC isn't always the best option for your finances. Let me help you figure out when this product is the best option and when you should look into other options.
A HELOC is a good idea when you have:
You've built up real equity in your home, either by making a down payment, paying your mortgage, or seeing the value of your home go up. AmeriSave usually wants you to have at least 15–20% equity left after the HELOC is funded. This means that you need to have at least 35–40% equity before you borrow.
Why this matters: If you don't have much equity and property values go down, you could end up underwater, which means you owe more than your home is worth. This makes it hard to sell or get a new loan if you need one.
You either refinanced or bought when rates were low (under 5%) and don't want to give up that rate by doing a cash-out refinance at today's higher rates.
The numbers back this up. If you have a first mortgage of $300,000 at 3.5% and need $60,000 in cash:
Cash-out refinance: $360,000 at 6.75% = $2,335/month. Keep your 3.5% mortgage and get a $60,000 HELOC at 7.75%: $1,347 + $388 = $1,735/month.
Even though you're paying a higher interest rate on the $60,000, you're saving $600 a month or $7,200 a year with the HELOC.
You're using the money for something that either makes your home worth more (renovations), lowers your debt with a higher interest rate (consolidation), or is a short-term need with a clear repayment schedule (emergency expense).
You have a steady income that will let you make your payments even if they go up because of a change in rates or a phase transition. You can get reasonable rates because your credit score is in the mid-600s or higher.
You know how the payments work, have a plan for both the draw and repayment periods, and have the self-control not to think of the credit line as "free money."
If you meet any of the following criteria, a HELOC might not be the best option:
If your first mortgage is already at or near 80% loan-to-value, you don't have much equity to work with. If you force a HELOC at higher LTV ratios, you will get worse rates, take on more risk, and your private mortgage insurance on your first mortgage may not cover you.
Wait until you've built up more equity through payments or appreciation, or think about getting a personal loan if you need money right away.
If you work for yourself and your income changes, are between jobs, or work in a field that is uncertain, taking on more debt backed by your home is risky. Payments on a HELOC that change from month to month add another level of uncertainty.
Another option is to build up your emergency fund first or get a fixed-rate home equity loan, where the payments are always the same.
If you're already having trouble making your current mortgage payment and only plan to make the minimum HELOC payments, you probably won't be able to afford the payment spike when the repayment period starts.
Another option is to be honest about your budget. You probably shouldn't borrow money if you can only make the interest-only payment. Think about getting a smaller loan or waiting until your finances get better.
A HELOC may not be a good idea if you plan to sell your home in the next two to three years. You will have to pay it off at closing, and with appraisal fees, closing costs, and interest, you might not get much use out of having the money for a short time.
For short-term needs with a set end date, you could also think about getting a personal loan or even a credit card with a 0% introductory APR that you can pay off before the promotional period ends.
If you take out a HELOC to buy a car, boat, RV, or other asset that loses value quickly, you'll be paying interest on it for years or even decades. After you pay off the HELOC, you've spent a lot more than the asset was worth.
You could also save up and pay in cash, or get an auto loan or another secured loan where the asset itself is the collateral, not your home.
If you're thinking about filing for bankruptcy because you're in so much debt, turning unsecured debt (like credit cards and medical bills) into secured debt (like a HELOC) could actually make things worse. You can get rid of unsecured debt in bankruptcy, but if you have a HELOC secured by your home, you still have to pay it off or you will lose the house.
Another option is to talk to a bankruptcy lawyer or credit counselor before making any decisions about debt consolidation.
Let me show you how HELOCs compare to other options:
Benefits of a home equity loan:
• A set interest rate and a set monthly payment
• Costs that are easy to plan for over the whole term
• Limits on the amount of money you can borrow that are often a little higher
Benefits of a HELOC:
• The ability to borrow, pay back, and borrow again
• Only pay interest on what you actually draw
• Can take advantage of lower interest rates
• Lower payments at the beginning of the draw period
If you need a specific amount of money for a one-time expense and want to be sure you'll be able to pay it back, a home equity loan is a good option. If you need to borrow money over time or need to borrow money on a regular basis, a HELOC is a good option.
Benefits of cash-out refinancing:
• One payment for the mortgage
• If you refinance from a high rate, you might get a lower interest rate than a HELOC.
• Usually a fixed rate and payment
Benefits of a HELOC:
• Keeps your current low-rate mortgage in place
• Closing costs are lower ($500–1,500 instead of $3,000–6,000)
• A quicker closing process
• No effect on the rate or term of the first mortgage
Your first mortgage rate is usually what makes this choice. A cash-out refinance might be a good idea if the rate is higher than 6%. If it's less than 5%, a HELOC is almost certainly a better financial choice.
Benefits of personal loans:
• No home at risk for collateral
• Set rate and term
• Getting money faster (sometimes on the same day)
• No need for an appraisal
Benefits of HELOC:
• Interest rates that are much lower (7–8% vs. 10–15%+ for personal loans)
• More money you can borrow (more than $50,000, which is usually the most you can borrow for a personal loan)
• Access all the time during the draw period
For smaller amounts (less than $15,000) where the difference in interest rates won't cost you much in real money, a personal loan might be worth looking into because it's easy to get and doesn't require putting up your home as collateral. Usually, the HELOC's lower rate wins when you need a lot of money or need it for a long time.
This is not even close. According to data from the Federal Reserve (2025), the average APR on credit cards is over 22%, which is almost three times the average rate on a HELOC.
For a balance of $20,000:
Credit card at 22%: $367/month minimum (interest-only would be higher) HELOC at 7.75%: $129/month interest-only
You save $238 a month, or $2,856 a year, with the HELOC. That's more than $14,000 in savings over five years. The only good thing about credit cards is that they are not secured, so you can file for bankruptcy and not lose your home.
Over the years, I've seen homeowners make some expensive mistakes with HELOCs. I'll show you the most common ones so you can stay away from them.
This is the biggest mistake. During the draw period, homeowners get used to making low interest-only payments and don't get ready for what will happen when they have to start paying back the loan.
Let's put a number on this mistake. You take out $70,000 from a HELOC at 7.75%:
$453/month for 120 months = $54,360 in interest-only payments. After 10 years, the balance is $70,000.
Total paid over 20 years: $155,160; repayment period: $840/month × 120 months = $100,800.
If you paid an extra $300 a month during the draw period, you would have paid $753 a month for 120 months, which is $90,360.
After 10 years, you still owe $34,000 (you paid off $36,000 in principal).
Total paid over 20 years: $139,320. The repayment period is 10 years, so $408/month × 120 months = $48,960.
You can save $15,840 over the life of the loan and lower your monthly payment by $432 by adding $300 each month during the draw period. That extra $300 a month at first costs you less overall than the payment increase you'll face later.
The psychological trap is that $300 more hurts when you're already stretched during the draw period. But that $432 difference in payments during repayment is even worse, and it comes at a time when you might not be able to change your plans.
HELOCs have variable rates that can go up a lot. If you only look at the current rate when making your budget, you could get into trouble if rates go up.
Let me show you how risky it is. You borrow $80,000 at a rate of 7.75% today:
The current payment is $517 per month, which is just interest.
If rates go up 2% over the next few years to 9.75%:
New payment (interest only): $650 per month. Monthly increase: $133. Annual increase: $1,596.
The effect is even bigger if you're in the repayment period. A balance of $80,000 over ten years:
Monthly increase: $72; annual increase: $864; at 7.75%, $960; at 9.75%, $1,032.
Even a small 2% rate increase will cost you $864 to $1,596 more each year, and you won't have to borrow any more money.
The best thing to do is to put your budget through a stress test. If rates go up by 1% to 2%, will you still be able to pay your HELOC? If not, you might be borrowing too much or you should think about getting a fixed-rate home equity loan instead.
You shouldn't take out the full $100,000 just because you got approved for a credit line. Taking out more money than you need costs you extra interest and makes it harder to pay back.
Think about this. You want to remodel your kitchen, but you only need $40,000. You say to yourself, "I might as well get more money for a bathroom update too."
If you draw $100,000 instead of $40,000, you will have to pay back $60,000 more. The extra interest you will have to pay each month (at 7.75%) is $388. Over the 10-year draw period, you will have to pay back $46,560 more.
That's almost $46,560 in interest on money you didn't really need right away. Even if you end up using it for the bathroom, you've paid interest on money that has been sitting around for years.
The better way is to only draw what you need for the task at hand. You can still use your HELOC credit line in the future, and you can borrow more money later if you really need it. You will pay thousands less in interest and still have options.
A lot of homeowners think that all HELOC interest is tax-deductible, but that's not true anymore since the 2017 Tax Cuts and Jobs Act.
The IRS says that you can only deduct HELOC interest if:
If you use a HELOC to pay off debt, buy a car, go on vacation, or do anything else that isn't home improvements, the interest isn't tax-deductible. During the draw period, the interest on a $50,000 HELOC at 7.75% is $3,875 per year that you can't deduct.
If you think you can deduct your taxes when you're in the 24% tax bracket, you're expecting a $930 tax break that won't happen. You might owe taxes or get a smaller refund than you thought because of that mistake.
Keep track of how you spend your HELOC money in detail. You can only deduct the interest on the $40,000 you used to remodel your kitchen (80% of your total interest in this case).
Your HELOC is a second mortgage, which means it is in second lien position behind your first mortgage. A lot of people don't know how important this is.
The HELOC makes it harder to refinance your first mortgage. Most lenders for first mortgages want all junior liens to be subordinated (agree to stay in second place) or paid off completely. Some lenders for HELOCs charge $300 to $500 in fees to subordinate. Some people won't subordinate, so you have to pay off the HELOC before you can finish refinancing your first mortgage.
If you need to sell your home and its value goes down, the first mortgage gets paid off first, followed by the HELOC. If you're underwater (meaning you owe more than the house is worth), the worst thing that could happen is that you'd have to bring cash to the closing to pay off both loans.
If you don't pay, the first mortgage lender can take your home, and the HELOC lender might not get anything. This is why HELOC lenders charge more than first mortgages and are more careful about how much money they will lend you. They are in a more dangerous situation.
Knowing this lien position will help you decide how much to borrow and whether a HELOC is right for you in the long run. A HELOC could make it harder to refinance your first mortgage in the next few years if you think you might do so.
The most dangerous mistake is in your head. Some homeowners treat HELOC funds like free money instead of a loan against their home because they are so easy to get (many lenders offer checks or credit cards linked to the line).
I've seen this happen too many times: a homeowner gets a HELOC to make improvements to their home. They still have credit left over after the renovation is done. You can easily write a $5,000 HELOC check for a vacation. Then there were car repairs that came out of nowhere, and then there were gifts for the holidays. They've already taken out $30,000 more than they planned to use it for.
They could be paying interest on their vacation and car repairs for up to 20 years. When you add in 20 years of interest at 7.75%, that $5,000 vacation ends up costing $9,600. If someone had told you the trip really cost $9,600, would you have gone? Not likely.
Because the credit line stays open during the draw period, HELOCs require more discipline than other loans. The temptation is gone once you spend the money on a regular loan. With a HELOC, the temptation is there every month for ten years.
Before you open the HELOC, make sure you know exactly what you will and won't use it for. Some homeowners even ask their lender not to send checks or cards, so they have to call or go to the bank to make a draw. That extra friction can stop people from borrowing on the spot.
A HELOC can be a great way to get to your home equity without breaking the bank, and you can make payments whenever you want during the draw period. With rates averaging between 7.75% and 8.00%, HELOCs are a good choice for homeowners who want to keep their current low-rate first mortgages.
Understanding the two-phase structure and making plans for both from the start is the key to successfully managing HELOC payments. During the draw period, that easy interest-only payment is only temporary. Your monthly payment could easily double when you start paying back the loan. If you plan for the increase or, even better, pay down the principal during the draw period, you won't be shocked by the payment and you'll save thousands in total interest.
We help homeowners set up HELOCs at AmeriSave that meet their short-term needs and long-term financial goals. You can easily model different situations with our digital tools, and our team can help you understand exactly what your payments will look like over the life of your loan.
Your specific situation will determine the best HELOC strategy for you: why you need the money, how much you need, what your income looks like, and what your financial goals are. Take the time to carefully run the numbers, test your budget against rate hikes and payment changes, and only borrow what you really need. You shouldn't put your home at risk by taking on debt that you can't easily pay back.
If you're thinking about getting a HELOC, use the calculator at the top of this page to find out how much your payments would be during the draw and repayment periods. Try out different situations: what if you pay more principal? What if the rates go up by 1%? What if you pick a longer time to pay it back? Knowing these numbers before you sign on the dotted line will help you make the best choice for your money.

HELOC payment calculators give you pretty good estimates based on the information you give them, but they make assumptions that might not be exactly what you experience. The main problem is that calculators usually use a fixed interest rate to figure out payments, but your actual HELOC rate will change with the prime rate over the course of the loan. Your actual payments could be lower than expected if the Federal Reserve keeps cutting rates like it has been doing through 2025. On the other hand, if rates go up again, your payments will be higher.
Calculators also usually assume that you take out the full amount right away and keep that amount throughout the draw period, which may not be how you really use the credit line. Your actual payments will be different from what the calculator says if you take money out slowly or pay down the principal during the draw period. Also, most calculators only show payments on the principal and interest, not fees like yearly maintenance fees or costs that come with drawing money. Ask your lender for a payment schedule that shows your intended draw pattern and includes all applicable fees for the most accurate projection for your situation. During the application process, AmeriSave gives you personalized payment estimates that take into account your specific borrowing plan.
When interest rates go down, your HELOC payment automatically goes down on the next date that your rate changes, and you don't have to do anything. This is one of the main benefits of a variable-rate HELOC over a fixed-rate loan. Market data from late 2025 shows that HELOC rates have dropped more than two percentage points from their 2023 highs. This means that people who already have HELOCs will have to pay less each month. The way it works is that the Federal Reserve lowers its benchmark rate. Within a day or two, the prime rate drops by the same amount. Then, at your next scheduled adjustment period, which is usually monthly or quarterly depending on your loan terms, your HELOC rate goes down.
If you have a $60,000 HELOC balance at 8.25% and are only paying interest, your monthly payment is about $413. If the Fed lowers rates by 0.5% and your HELOC rate drops to 7.75%, your payment goes down to about $388. This saves you $25 a month or $300 a year without you having to do anything or refinance. Even though you're paying down the principal each month, rate drops still lower your payment during the repayment period, but not as much as they would if you weren't. But the opposite is also true: if rates go up, your payment goes up automatically. This is why you should stress-test your budget before getting a HELOC to make sure you can still make payments even if rates go up by 1% to 2% from where they are now.
Yes, most HELOCs let you pay more than the minimum monthly payment. This can save you a lot of money in interest and make it easier to switch from the draw period to the repayment period. During the draw period, when you're only paying interest, any extra money you pay goes straight to lowering your principal balance. This lowers your future interest charges right away because you only pay interest on your outstanding balance. Most of the time, there are no penalties for paying extra or even paying off your HELOC early. However, some lenders charge fees for closing the credit line early, within the first two to three years.
Extra payments can have a big effect on your finances. If you have a $50,000 HELOC at 7.75% with payments of $323 a month that only cover the interest, If you add $200 to your principal payments every month during your 10-year draw period, your balance will drop to about $26,000 by the time you start paying it back. This will cut your payment period payment in half, from about $600 to $312. You'll save about $17,680 in interest over the course of the 20-year loan. We at AmeriSave suggest that borrowers who can afford it treat their HELOC like a principal-and-interest loan from the start instead of making minimum interest-only payments. This helps them develop good payment habits and avoids the stress of a sudden payment increase when the draw period ends. Before making large extra payments, make sure that your lender doesn't charge any fees for lowering the principal and that the extra payments are going toward the principal instead of being held as a prepayment of future interest.
When the draw period ends and you enter the repayment phase, your HELOC payment usually goes up a lot. The exact amount depends on your balance, interest rate, repayment term, and whether you made any principal payments during the draw period. If you only made interest-only payments during the draw period, your monthly payment will likely go up by about two or three times when you start paying back the loan. Recent examples from industry analysis (October 2025) show that a $50,000 HELOC balance at current rates of about 7.75% would cost about $323 per month during the draw period with interest-only payments. After that, it would cost about $600 per month during a 10-year repayment period or $472 per month during a 15-year repayment period.
The biggest rise happens when you switch to a shorter repayment period. If you had a $75,000 balance at 7.75%, your monthly payments would go from $484 during the interest-only period to about $900 for a 10-year repayment (an increase of $416), $708 for a 15-year repayment (an increase of $224), or $622 for a 20-year repayment (an increase of $138). This is why financial advisors often tell people to stress-test their budget before getting a HELOC: can you afford to pay twice as much when you have to start paying it back in ten years?
If the payment increase seems too much to handle, you have a few options to lessen the effect: during the draw period, start paying down the principal to lower your balance before repayment starts; choose a longer repayment period to spread the principal payments over more years (though this will cost you more in interest); or consider refinancing your HELOC into a home equity loan with a fixed rate and longer term when the draw period is about to end. Some lenders also let you lock in all or part of your balance at a fixed rate before the repayment period starts.
This makes your payments more predictable. Planning for this change from the day you open your HELOC is important for good management. You don't want to be surprised by it 10 years later.
The main things that will help you decide between a HELOC and a home equity loan are how you plan to use the money and whether you want to be able to change your payments or know for sure when they will be due. A HELOC is a better choice if you need to borrow money over time instead of all at once, if you only want to pay interest on what you actually borrow instead of the whole loan amount, if you're okay with interest rates that change and monthly payments that change, or if you want to take advantage of interest rates that might go down without having to refinance. HELOCs are great for projects that cost money over time, like a multi-phase home renovation, or as a financial safety net that lets you keep money on hand for emergencies but not have to use it.
If you need a certain amount of money for a one-time expense, want to know exactly how much your monthly payment will be for the whole loan term, are worried about interest rates going up and want to lock in today's rate, or just want a simpler loan structure without separate draw and repayment periods, a home equity loan is a better choice. Home equity loans are great for projects with known, fixed costs, like paying off a certain amount of debt or making a big purchase.
Market data shows that home equity loans and HELOCs have similar rates right now, with both averaging around 8% in late 2025. Home equity loans usually have fixed rates, while HELOCs have variable rates. This means that the real cost comparison depends on where interest rates go in the future. If rates drop a lot, HELOC borrowers automatically benefit, but home equity loan borrowers would have to refinance (which would cost them more money) to take advantage. When rates go up a lot, home equity loan borrowers are safe because their rates stay the same. But HELOC borrowers have to pay more.
We at AmeriSave help you compare the two options side by side based on your specific borrowing needs, financial situation, and how you plan to use the money. Some borrowers choose a combination approach, getting a home equity loan for known, immediate needs and keeping a smaller HELOC available for future flexibility. The most important thing is to choose a loan structure that fits how you plan to use the money, not just pick one product or the other without thinking about how you'll really use it.
Most lenders require a minimum credit score of 620-640 to qualify for a HELOC, though the best rates and terms go to borrowers with scores of 740 or higher. Your credit score has a big effect on whether you qualify and what interest rate you get. This, in turn, affects your monthly payment for the entire life of your HELOC. If your credit score is above 740, you usually get rates that are close to the prime rate plus a small margin of 0–0.5%. If your score is between 680 and 739, you might see margins of 0.5–1.5%. If your score is between 620 and 680, you might see margins of 1.5% or higher if you qualify at all.
Your credit score has a big effect on how much you pay in dollars. A borrower with a 760 credit score might get a rate of 7.25% (prime plus 0.25%) on a $50,000 HELOC with a current prime rate of 7.00%. This would mean a monthly payment of $302 just for interest. Someone with a 680 score might be able to get an 8.00% loan (prime plus 1.00%), which would mean a $333 payment. Because of the lower credit score, that's $31 more a month or $372 more a year, which adds up to thousands of dollars over the life of the loan.
Lenders look at more than just your credit score. They also look at your debt-to-income ratio (which should be 43% or lower), your payment history (which should show no late mortgage payments in the last 12 months), and your overall credit profile, which includes the length of your credit history and the types of credit accounts you have. If your credit score is close to the line, it can save you a lot of money to work on it for a few months before applying. Pay down your credit card balances to less than 30% of your credit limits, make all of your payments on time, and fix any mistakes on your credit reports. If your credit score goes up by 20 to 30 points, you may be able to get a better deal with a lower interest rate. If you're close to qualifying for a loan but not quite there yet, AmeriSave can help you figure out how to improve your credit so that you can get the best terms when you do apply.
The Tax Cuts and Jobs Act of 2017 says that you can only deduct HELOC interest on your federal income taxes in certain situations. If you use the money you borrowed to buy, build, or make major improvements to the home that secures the HELOC, you can deduct the interest. You must itemize your deductions instead of taking the standard deduction, and your total mortgage debt must not be more than $750,000 (or $375,000 if you are married and filing separately). The IRS says that "substantial improvement" means work that makes your home more valuable, extends its useful life, or makes it more useful for new purposes. Examples include adding a room, remodeling a kitchen or bathroom, replacing a roof, or upgrading HVAC systems. Regular repairs and maintenance that only keep the house in good shape don't count.
If you use your HELOC for things other than home improvements, like paying off credit card debt, buying a car, going on vacation, or paying for school, you can't deduct the interest on your taxes. This is a big change from the rules before 2017, when you could deduct HELOC interest no matter how you used the money. You can only deduct the interest on the part of your HELOC that you use for home improvements if you use it for more than one purpose. For example, if you use $40,000 for a kitchen remodel and $10,000 for debt consolidation, you can only deduct the interest on the kitchen remodel. In this case, you would have to keep track of how much you used and only deduct 80% of your interest.
It's very important to keep detailed records of how you spend your HELOC money, such as bills, receipts, and canceled checks that show you paid contractors or home improvement suppliers. If you want to claim the deduction, the IRS may ask for this proof. Keep in mind that you can only get the deduction if you itemize instead of taking the standard deduction. For single filers, the standard deduction is $14,600, and for married couples filing jointly, it is $29,200 in 2025. It doesn't make sense for many homeowners to itemize unless their total deductions (like mortgage interest, state and local taxes, charitable contributions, etc.) are more than the standard deduction. This is especially true after the tax law changes in 2017 that made the standard deduction much higher.
Because these rules are so complicated and making a mistake could cost you money in taxes, talk to a tax professional about your situation before assuming that your HELOC interest will be deductible. The tax benefit can be big (it could save you 24–37% of the interest cost, depending on your tax bracket), but only if you meet all the requirements and the deduction is actually good for you given your overall tax situation.
If you can't pay your HELOC, you could default on a loan that is secured by your home. This could lead to foreclosure. The consequences get worse over time, and the sooner you deal with the issue, the more choices you have for fixing it. If you miss one payment, you usually have to pay a late fee (usually $25–50 or a percentage of your payment) and the credit bureaus will be notified after 30 days, which hurts your credit score. If you miss two or three payments, the lender will usually step up their collection efforts, which may include phone calls and letters. Your credit score will also drop significantly when the 60-day and 90-day late payment marks show up on your credit report.
If you miss payments for 90 to 120 days, the lender may declare your HELOC in default and demand full payment right away. This is known as acceleration. The lender can start the foreclosure process to take your home and sell it to get their money back if you can't pay the full amount. Because your HELOC is in second lien position behind your first mortgage, things get even more complicated. If the HELOC lender forecloses, they have to pay off the first mortgage as well in order to finish the foreclosure. Otherwise, the first mortgage lender could foreclose first, leaving the HELOC lender with nothing to recover.
If you think you might have trouble making payments, call your lender right away before you miss any. Many lenders, like AmeriSave, have programs to help people who are having trouble making their payments. These programs might let you lower your payment for a short time, extend the draw period, postpone principal payments, or change the terms of the loan. These choices are almost always better than letting the loan go into default. If you're having trouble with your money because of a temporary problem like losing your job, having a medical emergency, or having a family emergency, explain your situation and send proof. Lenders are more likely to work with borrowers who talk to them ahead of time instead of just stopping payments without saying why.
If your hardship is more permanent or severe, you might need to consider other options like selling your home before foreclosure damages your credit severely, paying off or settling the HELOC using other assets or a personal loan if available, or in extreme cases, consulting with a bankruptcy attorney about whether bankruptcy protection might be appropriate for your situation. Don't ignore the problem or stop talking to your lender, no matter what you do. The sooner you deal with payment problems, the more choices you have and the less harm you'll do to your credit and financial future. Keep in mind that this is a loan secured by your home. If you don't pay back a credit card, the worst thing that can happen is that your credit score will go down and your wages may be garnished. If you don't pay back a HELOC, you could lose your home. Don't ignore any problems with payments; deal with them right away.
Throughout the life of a HELOC, from the time you apply for it to the time you pay it off, it will have an effect on your credit score in many ways. When you first apply for a HELOC, it shows up as a hard inquiry on your credit report. This usually lowers your score by 5 to 10 points for a short time, but it goes back up after a few months. Once you get the HELOC, it shows up on your credit report as a revolving credit account, like a credit card. This new account lowers your average account age at first, which can also cause a small, temporary drop in your score.
But a HELOC can also help your credit score in a number of ways over time. It raises the amount of credit you have available, which can lower your overall credit utilization ratio (the percentage of your available credit that you're using). Credit utilization is a big part of credit scoring, and it's usually best to keep it below 30%. So, if you have a big HELOC credit line that you're not using all of, it could actually help your score. Also, paying all of your HELOC bills on time adds to your positive payment history, which is the most important thing that goes into your credit score. It makes up about 35% of your FICO score. The longer you keep the HELOC and make all your payments on time, the better it is for your credit score.
The major credit bureaus say that HELOCs also add to your credit mix, which makes up about 10% of your score. Having both revolving credit (like credit cards and HELOCs) and installment loans (like mortgages and auto loans) can help your score more than having just one type of credit. Even if you're only paying interest during the draw period, your on-time payments are still reported positively. When you start paying off the principal during the repayment period, your credit reports show the balance going down, which helps your score even more over time.
If you don't handle the HELOC correctly, the bad effects will happen. Using your full credit line right away raises your credit utilization, which can hurt your score. Not making payments has a very bad effect. Missing payments for 30, 60, or 90 days will hurt your score more and more. FICO says that if you had great credit before, a single 30-day late payment can drop your score by 60 to 80 points. A 90-day late payment is even worse. If you don't pay back a HELOC or go through foreclosure, your score could drop by 150 to 200 points or more and stay on your credit report for seven years.
The best way to manage your HELOC's effect on your credit is to always make your payments on time, avoid taking out more than you need to keep your utilization reasonable, pay down the balance over time instead of keeping a large balance forever, and keep the credit line open even after you pay it off (as long as there is no annual fee) to keep your good account history and available credit. We send your payment history to all three major credit bureaus every month at AmeriSave. This means that being responsible with your HELOC can help you build and keep strong credit over time. Just keep in mind that the most important thing is to always pay your bills on time. Everything else about improving your credit score is not as important as having a perfect payment history.
Yes, you can refinance your HELOC to get better terms, lower your interest rate, or change the way your loan works. However, the process and benefits will depend on your situation and the state of the market right now. HELOC borrowers who want to change the terms of their loan have a number of refinancing options. Refinancing your HELOC into a new HELOC with a different lender who offers better terms is the most common way to do this. If your credit has improved, you might be able to get a lower interest rate, negotiate better terms, or reset the draw period to get more years of payment flexibility before you start paying back the loan.
You could also change your HELOC into a fixed-rate home equity loan. This would get rid of the risk of variable rates and give you predictable monthly payments for the life of the loan. This is especially appealing when you're getting close to the end of your draw period and have to start paying more in principal and interest, or when interest rates are low and you want to lock in a good rate before they go up again. Recent market data shows that home equity loan rates are around 8.00%, which is about the same as HELOC rates. However, with a home equity loan, you know exactly how much you'll have to pay each month.
A third option, which is less common, is a cash-out refinance of your first mortgage. This pays off both your current first mortgage and your HELOC, combining them into one new first mortgage. If you can get a rate on the new combined mortgage that is the same as or lower than the rate on your current first mortgage, then this makes sense financially. Many homeowners had first mortgages with rates between 3% and 4% from 2020 to 2022. Right now, mortgage rates are around 6.5% to 7%. So, unless your first mortgage rate is already high, a cash-out refinance doesn't usually make sense right now.
Getting a new HELOC and refinancing a HELOC are similar processes. You'll need to have your credit checked, your home appraised or valued, and your income verified. You'll also have to pay closing costs, which usually range from $500 to $2,500, depending on the lender and whether an appraisal is needed. We can help you figure out if it makes sense to refinance your HELOC at AmeriSave. We'll look at the possible rate improvement, the closing costs you'd have to pay, and how long you plan to keep the new loan. If the interest rate goes down by at least 0.5–1.0%, you plan to keep the new loan for at least 2–3 years to make up for the closing costs, or you're switching from a variable to a fixed rate for payment certainty even if the rate is the same, refinancing is usually worth it.
Timing is an important thing to think about. Refinancing might not be a good idea if you're currently in the draw period with interest-only payments and you're happy with your current rate. This is because you would have to pay closing costs without getting much benefit. But if you're getting close to the end of your loan term and are worried about the payment going up, refinancing into a home equity loan with a longer fixed term could help you a lot with your payments. Also, if interest rates have dropped a lot since you opened your HELOC (which they did from 2023 to 2025) and your credit score has gone up, refinancing could get you a much better rate that saves you thousands of dollars over the life of the loan.
Before you refinance, make sure to check with your current lender to see if they charge any fees for paying off your loan early or for terminating your loan early. These costs should be included in your refinancing calculation. You should also make sure that the value of your home is stable or has gone up, because you need enough equity to get the refinancing. If property values have gone down in your area, it might be hard for you to get a new HELOC or home equity loan with the same credit line amount. Lastly, think about your long-term financial goals. If you plan to sell your home in the next year or two, the costs of refinancing might not be worth the short-term benefit. But if you're going to stay where you are for a while and refinancing lowers your interest rate or changes your payment schedule in a big way, it can be a good financial move that saves you thousands of dollars and gives you more peace of mind about your money.
