If your HELOC draw period is ending in 2026 or 2027, here’s the short version: the day it ends, your interest-only payments stop and your balance starts amortizing. On a $50,000 balance at 8%, that takes your monthly payment from about $333 to about $478 — a 43% jump overnight, on the exact same balance. If your repayment term is 10 years instead of 15, the jump is closer to 82%.
This isn’t a rare edge case. TransUnion data shows about 1.2 million HELOCs were originated in 2016 and another 1.4 million in 2017, and most carried the standard 10-year draw period — so roughly 2.6 million lines flip into repayment across 2026 and 2027. If you opened yours in that window and you’ve been paying interest only, the clock is already running. The good news: you’ve got five real options, and the best ones work only if you start before the flip, not after.
What Actually Happens the Day Your Draw Period Ends
A HELOC has two phases, and most borrowers only ever think about the first one.
During the draw period — typically 5 to 10 years, with 10 years the most common — your line works like a credit card secured by your house. You borrow what you need, repay it, borrow again, and your minimum payment is usually interest only. A $50,000 balance at 8% costs you about $333 a month, and after ten years of paying exactly that, you still owe $50,000. Nothing about the payment feels urgent, which is exactly the problem.
Then the draw period ends, and three things change at once:
- You can no longer draw. The credit line closes. Even if you’ve repaid part of the balance, you can’t borrow it back.
- Interest-only payments end. Your minimum payment now has to cover principal too.
- The balance amortizes. Your lender spreads whatever you still owe across the repayment period — typically 10 to 20 years — in fixed principal-and-interest payments.
There’s no grace period and no ramp-up. Your first full principal-and-interest payment is due one billing cycle after the draw period closes. The date was set the day you signed the agreement, and it doesn’t move because you weren’t watching it.
| Draw period | Repayment period | |
|---|---|---|
| Typical length | 5–10 years (10 most common) | 10–20 years |
| Can you borrow? | Yes, up to your limit | No — line is closed |
| Minimum payment | Usually interest only | Principal + interest |
| Balance after 10 years of minimums | Unchanged | Shrinks every month |
| Rate | Usually variable (prime + margin) | Usually still variable |
Most HELOCs stay variable through repayment, so your new, higher payment can still move up or down with the prime rate. The prime rate was 7.00% as of October 29, 2026, according to the Federal Reserve’s H.15 release, and the national average HELOC rate sat around 8.58% as of November 6, 2026.
The Payment Shock, in Real Numbers
Forget the abstract warnings. Here’s the math, worked out with standard amortization at 8% — close to the current national average HELOC rate. Every figure below is a modeled estimate, not a quote from your lender: your actual payment depends on your rate, your repayment term, and whether your lender’s minimum-payment formula matches the standard one. But the shape of the shock is the same for everyone.
| Balance at draw-end | Interest-only now (8%) | New payment, 15-yr repayment | Monthly increase | New payment, 10-yr repayment | New payment, 20-yr repayment |
|---|---|---|---|---|---|
| $25,000 | $167 | $239 | +$72 (+43%) | $303 | $209 |
| $50,000 | $333 | $478 | +$145 (+43%) | $607 | $418 |
| $75,000 | $500 | $717 | +$217 (+43%) | $910 | $627 |
| $100,000 | $667 | $956 | +$289 (+43%) | $1,214 | $836 |
A few things worth noticing in that table:
The repayment term matters more than the balance. Stretch the same $50,000 over 20 years and the new payment is $418 — still a 25% increase, but $60 a month less than the 15-year version. Squeeze it into 10 years and it’s $607, an 82% jump. If your lender set a 10-year repayment term, your shock is nearly double the headline number. Check your agreement for the term, not just the date.
LendingTree’s own example tells the same story. In its guide to HELOC draw periods ending, LendingTree walks through a $25,000 balance on a fixed-rate HELOC at 7.75%: about $147 a month on average during the draw period, then $300 a month once the 10-year repayment period starts. The payment more than doubles — and LendingTree calls this “payment shock” by name, because it’s the industry’s term for it, not a scare phrase. LendingTree’s full guide is worth reading alongside this article.
The interest total is the part nobody quotes you. That $50,000 balance at 8% over 15 years costs about $36,040 in total interest during repayment alone. On $100,000, it’s roughly $72,080. Every dollar of principal you pay down before the flip shrinks both the monthly payment and that total.
Why 2026–2027 Is the Big Flip Window
This isn’t a slow, steady problem. It’s a wave with a date on it.
HELOC originations surged in the mid-2010s as home prices recovered and equity piled up. TransUnion counted 1.2 million new HELOCs in 2016 and projected 1.4 million in 2017 — and most of those loans were written with the standard structure: a 10-year draw period followed by a 10- to 20-year repayment period. Do the arithmetic and you get a cohort of roughly 2.6 million borrowers whose draw periods end in 2026 and 2027.
The balances are bigger than they used to be, too. Experian’s 2026 data puts the average HELOC balance at $52,347 — up 11.2% in a year — with total HELOC debt nationwide at $427.6 billion and the average credit limit at about $129,000. More than 200,000 new HELOCs have opened every month since April 2025, so fresh lines are still being written even as the 2016–2017 cohort hits repayment. Experian’s HELOC study has the full breakdown.
And the rate backdrop makes the flip steeper than it would have been five years ago. Borrowers who opened HELOCs in 2016–2017 started with rates near 4–5%, then watched their interest-only payments creep up as the prime rate rose. By late 2026, the average HELOC rate is around 8.58%. So many borrowers get hit twice: first by rate increases during the draw period, then by principal amortization at repayment. A borrower who drew $75,000 in 2020 at 4.5% paid about $281 a month in interest. At today’s rates, that same balance costs roughly $500 a month in interest alone — and once repayment starts, the payment jumps again to over $700.
If your draw period ends in 2026, you’re in the first wave. If it ends in 2027, you have a few months of runway. Either way, the move is the same: find your end date now, run your numbers, and pick a strategy before the lender picks one for you.
The Balloon-Payment Trap (Read Your Agreement for This One)
Most HELOCs amortize the balance over the repayment period. Some don’t. A minority of HELOC agreements include a balloon payment clause: when the draw period ends, the entire outstanding balance comes due at once — as a single lump sum.
The Consumer Financial Protection Bureau (CFPB) specifically warns borrowers about this: some home equity plans require you to pay the full balance when the draw period ends, and your monthly payments during the draw period may not have reduced the principal at all. If your balance is $50,000 and your plan has a balloon clause, your “payment shock” isn’t $478 a month — it’s a $50,000 bill.
Balloon-payment HELOCs are uncommon — a loan with a balloon payment is a non-qualified mortgage under federal rules, which makes it harder for lenders to sell — but “uncommon” is no comfort if yours is one of them. Here’s how to check:
- Find your original HELOC agreement — the promissory note or the initial disclosure, not your monthly statement. The draw-period end date and the repayment terms live there.
- Search for the words “balloon,” “lump sum,” and “entire balance due.” The disclosure is required to show how a balloon payment would work, including an example on a $10,000 balance.
- Call your lender and ask directly: “When my draw period ends, does my balance amortize, or is the full balance due?” Get the answer in writing if you can.
If you do have a balloon clause, the options below still apply — but the timeline is brutally short. A refinance or home equity loan needs to close before the balloon date, not after. Start that process at least 90 days out, and treat it as urgent from day one.
Your 5 Options Before the Flip
You have more leverage before the draw period ends than after it. Once you’re in repayment, the lender has no reason to renegotiate. Here’s the playbook, from the simplest move to the most involved.
Option 1: Pay down the principal now
This is the least exciting option and the most effective one. Every dollar you pay toward principal during the draw period is a dollar that doesn’t get amortized at repayment — and it shrinks both your new monthly payment and your total interest.
The math is friendly: paying an extra $200 a month toward principal on a $50,000 balance for the last year of your draw period knocks the balance to about $47,600. At 8% over 15 years, that cuts your repayment payment from $478 to about $455 — $23 a month, every month, for 15 years, plus roughly $1,700 less total interest. Pay down $10,000 and the payment drops by about $96 a month.
Check first that your lender allows extra principal payments without a prepayment penalty — most HELOCs do, but confirm it in writing. Then redirect whatever you can: the money you’d spend on the next draw, a tax refund, a bonus. This is also the only option that works even if your credit has slipped or your home value has dropped, because it doesn’t require anyone’s approval.
Option 2: Renew or extend the draw period with your current lender
Some lenders will let you renew your HELOC at the end of the draw period — essentially opening a new draw period on the same line, sometimes with a fresh appraisal and underwriting. Others won’t, or will only renew if your credit and home value still qualify.
Renewal is worth asking about because it’s usually the cheapest path: no new loan, no closing costs beyond an appraisal, and your interest-only payments continue. But treat it as a maybe, not a plan. Lenders aren’t obligated to renew, and the ones that do will re-underwrite you — credit check, income check, home valuation. If your credit score has dropped or your equity has shrunk, renewal can be denied.
Ask your lender 6 to 12 months before the draw period ends: “Do you offer draw-period renewals, what are the requirements, and what would the new rate be?” If they say yes, get the terms in writing and compare them against the other options. If they say no, you’ve just learned something important with time to act on it.
Option 3: Refinance into a new HELOC
If your current lender won’t renew, another lender might give you a brand-new HELOC — ideally one with a fresh 10-year draw period and, if you shop carefully, a lower rate or a lower margin over prime. This restarts the clock entirely: interest-only payments, full access to the line, and a decade before the next flip.
The catch is the same as any refinance: you have to qualify. Lenders look at your credit score, your debt-to-income ratio, and your remaining equity, and they’ll order an appraisal. Closing costs on a new HELOC are usually modest — often a few hundred dollars, sometimes waived — but they’re not zero. And the teaser-rate trap applies here too: some new HELOCs advertise a low introductory rate that resets higher after 6 to 12 months, so read the margin over prime, not the headline number. We covered how teaser rates and margins work in our guide to HELOC margins over prime and teaser rates — read it before you sign anything new.
Refinancing makes the most sense when your credit is strong, your home has gained value, and you still want the flexibility of a revolving line. It makes the least sense when you’re refinancing purely to avoid a payment you could afford — you’re just moving the cliff ten years down the road.
Option 4: Convert to a fixed-rate loan
Several lenders let you convert all or part of your HELOC balance to a fixed-rate loan when the draw period ends — sometimes called a fixed-rate lock option or a fixed-rate conversion. Your balance becomes a traditional installment loan with a set rate and a set monthly payment, usually over 10 to 20 years.
The appeal is certainty: your payment can’t rise with the prime rate, which matters if you believe rates will climb during your repayment period. The trade-off is that the fixed rate is usually higher than your current variable rate, and you lose the ability to re-borrow what you’ve repaid. Some lenders charge a conversion fee; some allow only one conversion per line; some let you convert in chunks, locking part of the balance while the rest stays variable.
Ask your lender whether a fixed-rate conversion exists on your plan, what rate they’d offer, and whether there’s a fee. Then compare the fixed payment against the amortized variable payment at today’s rate. If the fixed payment is close — within $20 to $30 a month — the certainty is often worth it.
Option 5: Replace it with a home equity loan or cash-out refinance
If you don’t need a revolving line anymore, a closed-end home equity loan can be the cleanest exit: you borrow a lump sum equal to your HELOC balance, pay off the line, and repay the loan in fixed monthly installments at a fixed rate. No more variable-rate surprises, no more draw period to track, and the payment is locked for the life of the loan.
A cash-out refinance rolls the HELOC balance into a new first mortgage — only sensible if your current mortgage rate is higher than what’s available now. Folding a $50,000 HELOC into a $300,000 mortgage at a worse rate to “solve” a $478 payment would be a costly mistake.
Both options depend on your credit profile. If your score has changed since you opened the HELOC, check where it stands before you apply — credit scoring rules changed in 2026, and the model your lender uses may not be the one you expect. Our piece on the 2026 mortgage credit score changes explains what’s different.
A 90-Day Countdown Plan
If your draw period ends within the next three months, work this list in order. If you have six months or more, do the same list, just with less panic.
Days 90 to 60: Get the facts. Find your agreement and confirm three things: the exact draw-period end date, the repayment term, and whether there’s a balloon clause. Call your lender and ask about renewal and fixed-rate conversion. Run your own numbers with the table above so you know your new payment to the dollar.
Days 60 to 30: Pick a strategy. Compare the five options against your situation. If you’re refinancing or taking a home equity loan, start the application now — appraisals and underwriting take weeks, and you don’t want the process spilling past your end date. If you’re paying down principal, make the largest extra payment you can afford this month.
Days 30 to 0: Lock it in. Confirm your new loan or renewal is closing on time. Set up autopay for the new amount. Rebuild your monthly budget around the repayment payment — and if the new payment doesn’t fit, call your lender’s hardship or loss-mitigation department before you miss a payment, not after.
After the flip: Stay ahead of the rate. Your repayment payment can still change if your rate is variable. Check your statement each month, and if the prime rate moves, recalculate.
What NOT to Do When the Draw Period Ends
Don’t ignore the lender’s letters. Your lender is required to send disclosures about the transition, and many send a notice a few months before the end date. If you’ve moved, or the letters go to an email you never check, update your contact details now.
Don’t draw more to cover the higher payment. Taking a final draw before the line closes to “pre-fund” the new payments just raises the balance you’re about to amortize. It’s borrowing to pay for borrowing.
Don’t assume you’ll refinance your way out at the last minute. Refinancing takes 30 to 45 days in the best case. If you start the week your draw period ends, you’ll be making the higher payment while the application is still in underwriting — and a denied application leaves you with no plan at all.
Don’t miss the first repayment payment. A missed payment on a home-secured loan hits your credit fast, and it weakens your negotiating position with the lender at the exact moment you need it most. Set a calendar reminder for the end date the day you read this.
Frequently Asked Questions
How do I find out when my HELOC draw period ends?
Check your original HELOC agreement or promissory note — the draw-period end date is in there, usually near the payment terms. It’s often not printed on your monthly statement. If you can’t find the paperwork, call your lender’s servicing line and ask for the “draw period expiration date” and the repayment term. Write both down.
Can I extend my HELOC draw period?
Sometimes. Some lenders offer a renewal or extension that starts a new draw period, but it’s not guaranteed — you’ll typically be re-underwritten, which means a credit check, income verification, and a home appraisal. Ask your lender 6 to 12 months before the end date. If renewal isn’t offered, refinancing into a new HELOC with a different lender restarts the clock the same way.
Will my payment really double when the draw period ends?
It can. LendingTree’s example has a $25,000 balance going from about $147 a month to $300 — more than double — on a 10-year repayment term. On a 15-year term at 8%, the jump is about 43% ($50,000 goes from $333 to $478). The size of the jump depends on your balance, your rate, and your repayment term: shorter terms mean bigger jumps.
What happens if I can’t afford the new repayment?
Call your lender before you miss a payment, not after. Options may include a hardship forbearance, a modified repayment schedule, a fixed-rate conversion at a longer term, or refinancing into a home equity loan with a longer amortization. Missing payments on a HELOC can lead to default and, ultimately, foreclosure, because the loan is secured by your home. If the balance is unmanageable, a nonprofit housing counselor approved by the U.S. Department of Housing and Urban Development (HUD) can help you negotiate — the service is typically free.
Does the interest on my HELOC stay tax-deductible during repayment?
It depends on what you used the money for. Under current federal tax law, HELOC interest is generally deductible only when the borrowed funds were used to buy, build, or substantially improve the home that secures the loan, within the federal debt limits. Interest on money used for anything else — debt consolidation, a car, a vacation — generally isn’t deductible. Confirm your situation with a tax professional.
Is a HELOC draw period ending the same as the loan maturing?
Not quite. When the draw period ends, the loan enters its repayment period and you keep paying monthly for another 10 to 20 years. Maturity is the final date when the entire remaining balance must be paid off. The exception is a balloon-payment HELOC, where the full balance comes due at the end of the draw period — in that case, the draw-end date effectively is the maturity date. Check your agreement to see which version you have.
