What is the HELOC repayment period?
The repayment period is the second and final phase of a HELOC — the phase most borrowers think about least, yet the one that demands the most financial preparation. It begins the moment the draw period ends and typically lasts 20 years. When repayment starts, everything changes simultaneously: the credit line closes, the payment structure shifts, and the minimum required payment increases significantly.
Five things that change the moment repayment begins:
- Credit line closes permanently — no new draws, no exceptions, no reopening
- Balance becomes fixed — whatever was outstanding on the last day of the draw period
- Payment jumps immediately — from interest-only to full principal + interest, same balance
- Revolving access ends — repaid principal cannot be re-borrowed
- 20-year clock starts — your payment is calculated to pay off the full balance in exactly 240 months
Interest-only • Revolving • Now closed
Full P+I • No new draws • Balance paid in full
When does the HELOC repayment period start?
The repayment period starts on a fixed calendar date set at closing — the month after the draw period ends. This date does not move. There is no notification period that triggers the start, no grace period after the draw period ends, and no option to extend the draw period.
How to find your repayment start date
- Check your HELOC closing documents — the draw period end date and repayment start date are listed in the original loan agreement
- Read your monthly statement — most lenders show “X months remaining in draw period” on each statement
- Log into your online account — most lenders display the draw period end date in the account dashboard
- Call your lender — any representative can confirm the exact date in seconds
The month-by-month transition
| Month | Draw period status | What you should do |
|---|---|---|
| Month 108–114 (yrs 9–9.5) | Open — 6–12 months remaining | Contact lender • Run payoff calculator • Model options |
| Month 115–119 (final months) | Open — last draws possible | Make any final draws • Voluntarily start P+I payments |
| Month 120 (draw period end) | CLOSED permanently | Credit line closes • Balance is frozen • No new draws |
| Month 121 (repayment start) | Repayment begins | First full P+I payment due • No grace period • No ramp-up |
| Months 122–360 (yrs 11–30) | Repayment active | Make monthly P+I payments • Consider early payoff |
How is your repayment payment calculated?
Your repayment payment is a standard fully amortizing monthly payment — calculated using the classic mortgage formula to pay off your entire remaining balance over exactly 20 years at the current interest rate.
The amortization formula
Payment examples at 8.5% rate — 20-year repayment
| Balance at repayment start | Monthly P+I | Total interest (20yr) | Total cost |
|---|---|---|---|
| $25,000 | $217/mo | $27,140 | $52,140 |
| $50,000 | $434/mo | $54,280 | $104,280 |
| $80,000 | $694/mo | $86,848 | $166,848 |
| $100,000 | $868/mo | $108,560 | $208,560 |
| $125,000 | $1,085/mo | $135,700 | $260,700 |
What affects your repayment payment
- Your balance on day one of repayment — the single biggest driver. A $10,000 lower balance saves $87/month for 20 years ($20,880 total)
- The current rate when repayment starts — your rate is still variable. A 1% higher rate on $80,000 adds ~$46/month ($11,040 over 20 years)
- Fed rate changes during repayment — the rate and payment can still change even after repayment starts. The rate caps still apply
Payment shock — the biggest HELOC repayment risk
Payment shock is the sudden, significant increase in your required monthly payment the moment the draw period ends — on exactly the same outstanding balance. It’s called “shock” because it’s immediate, mandatory, and often larger than borrowers expect.
Why payment shock happens
During the draw period, your minimum payment covered only interest — no principal reduction. The moment repayment starts, the same balance must now be paid off over 20 years through combined principal + interest payments. There is no transition, no phase-in, and no option to continue interest-only payments.
$567 interest • $0 principal
$567 interest + $127 principal
Payment shock at every balance level (8.5% rate)
| Balance | Draw IO payment | Repayment P+I | Monthly jump | Annual jump |
|---|---|---|---|---|
| $25,000 | $177/mo | $217/mo | +$40 | +$480/yr |
| $50,000 | $354/mo | $434/mo | +$80 | +$960/yr |
| $75,000 | $531/mo | $651/mo | +$120 | +$1,440/yr |
| $80,000 | $567/mo | $694/mo | +$127 | +$1,524/yr |
| $100,000 | $708/mo | $868/mo | +$160 | +$1,920/yr |
| $125,000 | $885/mo | $1,085/mo | +$200 | +$2,400/yr |
How to avoid or minimize payment shock
Payment shock is entirely predictable — and entirely preventable if you act during the draw period rather than waiting for month 121. Every strategy below is more effective the earlier it’s implemented.
Strategy 1: Pay extra principal during the draw period
The most powerful move. Every extra dollar of principal paid during the draw period directly reduces your repayment balance — and your repayment payment.
Strategy 2: Pre-adapt your budget 6–12 months early
Starting 6–12 months before repayment begins, voluntarily pay the full P+I amount as if repayment had already started. The difference between your IO minimum and the full P+I payment goes to extra principal. You adapt to the higher payment, reduce your balance, and enter repayment without a shock.
Strategy 3: Know your repayment payment from day one
Run the payoff calculator at closing, at year 3, at year 5, at year 8, and at year 10. Always know what your repayment payment will be. Never be surprised. The repayment payment is fully predictable years in advance — there is no excuse for being caught off guard.
Strategy 4: Stress-test at higher rates
Always calculate what your repayment payment would be at your current rate plus 2%. On $80,000: a 2% higher rate raises the repayment payment from $694 to $794/month. If that payment is unaffordable, reduce your draw balance now.
Your options when the repayment period starts
When the draw period ends, you are not locked into one path. Six distinct options exist — ranging from doing nothing to selling your home. The right choice depends on your balance, current rate, equity, and financial situation.
How to pay off your HELOC early during the repayment period
The repayment period is 20 years by design — but you don’t have to use all of them. Paying off your HELOC early during the repayment period is permitted on virtually every HELOC with no prepayment penalty. The interest savings are substantial.
Total cost comparison: 5, 10, and 20-year payoff ($80,000 at 8.5%)
| Payoff strategy | Monthly payment | Total interest paid | Total cost | vs 20-yr savings |
|---|---|---|---|---|
| Standard 20 years | $694/mo | $86,848 | $166,848 | — |
| Pay off in 15 years | $789/mo | $62,020 | $142,020 | Save $24,828 |
| Pay off in 10 years | $992/mo | $39,040 | $119,040 | Save $47,808 |
| Pay off in 5 years | $1,645/mo | $18,700 | $98,700 | Save $68,148 |
5 practical early payoff strategies
- Bi-weekly half-payments — Pay half your monthly payment every two weeks. Results in 26 half-payments per year = 13 full payments instead of 12. This alone saves approximately 2–3 years on a 20-year term and thousands in interest
- Annual windfall application — Apply any tax refund, bonus, inheritance, or asset sale proceeds directly to principal. Even a single $5,000 lump sum early in repayment saves $3,200+ in interest over the remaining term
- Rate-cut acceleration — When the Fed cuts rates and your monthly payment decreases, keep paying the old higher amount. The difference goes entirely to principal. This is the most painless way to build payoff momentum
- Round-up payments — If your payment is $694, pay $750. If $868, pay $900. The small, consistent overpayment compounds significantly over 20 years and builds a habit without budgetary strain
- Refinance to a shorter-term loan — If rates drop significantly from your current HELOC rate, refinancing to a 10-year fixed home equity loan can reduce both your rate and your term simultaneously
How amortization works during the HELOC repayment period
During the repayment period, each monthly payment is fixed — but the split between principal and interest shifts dramatically over time. Early payments are mostly interest. Late payments are mostly principal. Understanding this curve reveals exactly when extra payments have maximum impact.
Principal vs interest over 20 years ($80,000 at 8.5%)
The amortization by phase
| Repayment year | Monthly payment | Interest portion | Principal portion | Balance remaining |
|---|---|---|---|---|
| Year 1 (start) | $694/mo | $567 (81.7%) | $127 (18.3%) | ~$78,500 |
| Year 5 | $694/mo | ~$524 (75.5%) | ~$170 (24.5%) | ~$71,800 |
| Year 10 | $694/mo | ~$458 (66%) | ~$236 (34%) | ~$60,500 |
| Year 15 | $694/mo | ~$356 (51%) | ~$338 (49%) | ~$43,000 |
| Year 20 (final) | $694/mo | ~$9 (1.3%) | ~$685 (98.7%) | $0 — paid off |
What this means for early payoff timing
- Years 1–7 — Extra payments have maximum impact. Most of your regular payment is going to interest, so any extra principal directly reduces the high-interest portion of the balance
- Years 8–15 — Extra payments still very effective. Balance is declining at an accelerating rate
- Years 15–20 — Most of each payment is principal. Extra payments are less impactful. The balance is declining rapidly on its own
What happens if you can’t make HELOC repayment payments?
This is the section most HELOC guides skip — and the most important one for borrowers approaching repayment with budget uncertainty. HELOC default is fundamentally different from credit card default: your home is the collateral, and the consequences escalate quickly.
The default escalation timeline
If you’re struggling — act before day 15, not after
- Call your lender immediately — before missing the first payment if possible. Lenders have hardship programs, deferral options, and payment modifications available to borrowers who contact them proactively. These programs are typically unavailable to borrowers who have already defaulted
- Request a hardship deferral — Many lenders will temporarily suspend payments for 3–6 months for documented hardship (job loss, medical emergency). Interest continues to accrue but foreclosure is paused
- Contact a HUD-approved housing counselor — Free service that negotiates with lenders on your behalf. Find one at HUD.gov. They know what programs are available and how to access them
- Explore refinancing even in distress — If you have significant equity, refinancing before default is far better than after. A lender will not refinance a HELOC that is already in default
