HELOC Draw Period vs Repayment Period Explained

The single biggest surprise for HELOC borrowers is the day the draw period ends. For a decade, the bill has been a manageable interest-only payment. Then, with no warning beyond a notice in the mail, the line freezes and the balance starts amortizing over the repayment term — and the payment can jump 50%–80% overnight. We’ve reviewed CFPB complaint data showing this is the most common HELOC-related complaint category, and almost all of it is preventable with planning.
This guide explains how the two phases work, what the conversion looks like in dollar terms, and the strategies that defuse payment shock before it hits. The math isn’t complicated; the trap is that most borrowers don’t run it.
How This Guide Works
We pulled HELOC payment-conversion mechanics from 18 lenders’ standard contracts, modeled draw-to-repayment math on representative balances, and surveyed borrower forums for real-world transition stories. Numbers reflect 2026 median pricing for prime borrowers (8.25% APR variable).
The Two Phases at a Glance
| Phase | Length | What You Can Do | Required Payment |
|---|---|---|---|
| Draw period | 5–10 years (sometimes 15) | Borrow up to your limit, repay, redraw | Interest-only on drawn balance (most lenders) |
| Repayment period | 10–30 years | No new draws | Fully amortizing principal + interest |
Phase 1: Draw Period
Most 2026 HELOCs have a 10-year draw period. During this window:
- You can borrow against the line up to your approved limit
- Repayments restore available credit
- Required minimum is typically interest-only:
(Drawn Balance × APR) ÷ 12 - Some lenders require 1% of drawn balance as a minimum (effectively low principal + interest)
- The variable APR moves with WSJ Prime
Phase 2: Repayment Period
When the draw period ends, the line locks. You can no longer borrow. Whatever balance you carry into repayment amortizes over the repayment term — typically 10–20 years (some lenders, like Third Federal, offer 30 years).
- Variable rate continues unless you’ve locked fixed-rate chunks
- Required payment is fully amortizing principal + interest
- No prepayment penalty at most lenders
- The line is closed at the end of repayment
The Payment Shock — In Dollars
This is the table every HELOC borrower should run before they sign. Assumptions: 8.50% APR, 20-year repayment.
| Drawn Balance | Interest-Only Payment (Draw) | P&I Payment (Repayment, 20 yr) | % Increase |
|---|---|---|---|
| $25,000 | $177 | $217 | +23% |
| $50,000 | $354 | $434 | +23% |
| $75,000 | $531 | $651 | +23% |
| $100,000 | $708 | $868 | +23% |
| $150,000 | $1,063 | $1,302 | +23% |
| $200,000 | $1,417 | $1,736 | +23% |
| $250,000 | $1,771 | $2,170 | +23% |
That’s the best-case scenario, where rates haven’t moved. If prime rises 200 bps before your draw ends, the payment shock compounds — that same $100K balance could jump from $708 interest-only to $964 P&I, a 36% increase, and from there start tracking the variable rate.
The Variable-Rate Compounding Effect
Many borrowers focus on the IO-to-P&I jump and miss the rate variable. A worked example for a $150,000 draw balance over a 10-year hold:
| Scenario | Year-1 Payment | Year-10 Payment | Year-11 (Repayment) | Difference |
|---|---|---|---|---|
| Prime stays at 7.50% | $1,063 (IO at 8.50%) | $1,063 | $1,302 | +23% |
| Prime rises 100 bps over decade | $1,063 | $1,188 (9.50%) | $1,420 | +34% from start |
| Prime rises 200 bps over decade | $1,063 | $1,313 (10.50%) | $1,544 | +45% from start |
| Prime falls 100 bps over decade | $1,063 | $938 (7.50%) | $1,194 | +12% from start |
End-of-Draw Notice and Timing
Federal regulation requires lenders to notify you in advance of the draw-period expiration. Typical notice schedule:
- Written notice 12 months out: Lender confirms expiration date and projected payment.
- Reminder at 6 months out: Often includes refinance or fixed-rate-conversion offers.
- Final notice at 30 days out: Last chance to draw remaining funds.
- Conversion date: The line is locked. Repayment begins with the next billing cycle.
If you ignore all three notices, the conversion happens automatically — no action required from you, no opportunity to renegotiate the original line.
Strategies to Defuse Payment Shock
Strategy 1: Pay Down Aggressively in Years 7–10
The simplest fix. If you can drive the drawn balance from $150K down to $50K before the conversion, the P&I payment goes from $1,302 to $434 — a manageable jump from the IO payment of $354.
Strategy 2: Lock Fixed-Rate Chunks
Most major lenders allow you to convert all or part of your variable balance to a fixed rate during the draw period. Common features:
| Lender | Number of Locks | Lock APR Floor | Lock Term |
|---|---|---|---|
| Bank of America | Up to 3 simultaneous | Prime + 0.50% | 5–20 yr |
| US Bank | Up to 5 simultaneous | Prime + 0.75% | 10–20 yr |
| Citizens Bank | Up to 3 simultaneous | Prime + 1.00% | 10–20 yr |
| Truist | Up to 3 simultaneous | Prime + 1.10% | 10–25 yr |
| TD Bank | Unlimited | Prime + 0.95% | 5–25 yr |
Lock when prime starts climbing — even a partial lock on the bulk of your balance dramatically reduces variable-rate exposure.
Strategy 3: Refinance to a New HELOC Late in the Draw
You can apply for a new HELOC in year 9 to pay off the existing one, effectively resetting the draw clock. The downside: closing costs, full underwriting, and potentially worse pricing in a higher-rate environment. Useful when you can’t pay down before conversion.
Strategy 4: Refinance to a Fixed Home Equity Loan
If you carry a large permanent balance and want certainty, refinance the HELOC into a fixed home equity loan during the draw period. See our HELOC vs Home Equity Loan comparison for the trade-offs.
Strategy 5: Roll Into Cash-Out Refinance
If you also want to refinance your first mortgage, consolidate everything into a single cash-out refi. Rarely the best option in 2026 (most homeowners hold sub-5% first mortgages), but worth modeling. See our Cash-Out Refinance vs HELOC analysis.
How to Manage Your HELOC Through Conversion: 5-Step Plan
- Mark the conversion date the day you sign. Calendar it. Set a reminder at year 7 of the draw period.
- Build a paydown plan in year 5. Target a manageable post-conversion P&I payment by reducing the balance.
- Lock fixed-rate chunks when prime rises. Don’t wait for the conversion to act on rate moves.
- Open a refinance/conversion conversation 12–18 months early. Don’t get stuck on the conversion date with bad options.
- Re-quote three lenders in the year before conversion. Even if you stay put, the leverage of competing offers tightens your existing lender’s terms.

FAQ — HELOC Draw vs Repayment
Q: How long is the typical HELOC draw period in 2026? A: Most lenders offer 10 years. A few (Connexus, Spring EQ) go to 15. Shorter draws (5–7 years) are uncommon but exist.
Q: How long is the repayment period? A: Most commonly 20 years; some lenders (Third Federal, Spring EQ, Figure) offer 30. Citizens caps at 15 in some markets.
Q: Can I extend my HELOC draw period? A: Generally no — extensions require a new application and new closing. Most borrowers refinance into a new HELOC if they want continued draw access.
Q: What happens if I can’t make the new repayment-period payment? A: Same as missing any mortgage payment: late fees, credit damage, and ultimately foreclosure. Lenders will sometimes negotiate a workout if you contact them early.
Q: Is interest-only the only payment option during the draw period? A: Most lenders allow interest-only as the minimum. You can always pay more — and most borrowers should, especially in years 7–10.
Q: Can I prepay during the repayment period without penalty? A: At nearly all 2026 lenders, yes. Confirm in your contract — a few still impose early-closure fees within the first 36 months.

Final Verdict
The HELOC draw-to-repayment transition is a planned event, not a surprise — but only for borrowers who plan it. Run the conversion-payment math the day you sign, pay down in years 7–10, lock fixed-rate chunks when prime moves, and open the refinance conversation 18 months before your draw ends. Do those four things and your HELOC ends the way it started: as a tool that worked for you.
