What are the two phases of a HELOC?
Every HELOC is divided into two distinct phases: the draw period and the repayment period. Understanding how each phase works — and what changes at the transition — is essential before you open a line of credit against your home.
The draw period
The draw period is the window during which you can borrow from your line of credit. Think of it like a credit card with a credit limit tied to your home equity: you can pull funds, repay them, and pull again as long as you stay within your limit.
Key characteristics of the draw period:
- Typical length: 10 years, though lenders may offer 5–15 years
- Access to funds: You can draw as much or as little as you need, up to your approved credit limit
- Minimum payments: Usually interest-only on the outstanding balance
- Rate type: Most HELOCs carry a variable rate, so your payment can fluctuate month to month as the benchmark rate changes
- Optional principal payments: You are generally free to pay down principal at any time, which frees up available credit and reduces future interest
Because minimum payments during the draw period are interest-only, they can feel manageable — sometimes deceptively so. The balance you carry into the repayment period determines how large your future payments will be.
The repayment period
When the draw period ends, the line of credit closes. You can no longer borrow, and the focus shifts entirely to repaying what you owe.
Key characteristics of the repayment period:
- Typical length: 20 years, making total HELOC terms often 30 years combined
- Payment structure: Fully amortizing — each payment covers both principal and interest
- No new draws: The credit line is closed; you cannot reborrow repaid funds
- Rate type: Still variable for most HELOCs, though some lenders allow you to lock in a fixed rate at or before the transition
How do payments compare between the two periods?
The table below illustrates how a $50,000 balance behaves differently in each phase. These are illustrative examples, not quotes or guarantees.
| Draw period | Repayment period | |
|---|---|---|
| Phase length | Typically 10 years | Typically 20 years |
| Payment type | Interest-only (minimum) | Principal + interest (amortizing) |
| Can you borrow more? | Yes, up to your limit | No — line is closed |
| Monthly payment on $50,000 at ~7% rate | Approx. $292/month | Approx. $388/month |
| Balance change (paying minimums only) | Stays at $50,000 | Decreases to $0 over 20 years |
The jump from interest-only to fully amortizing payments is often called payment shock. On a large balance, the difference can be several hundred dollars per month. Planning for this transition is one of the most important parts of HELOC management.
What triggers the transition between periods?
The transition happens automatically on the date specified in your loan agreement — typically 10 years after the line opens. Nothing special is required on your end; your lender will notify you as the date approaches. At that point:
- Your ability to draw funds ends
- Your minimum payment increases to cover principal and interest
- The repayment clock starts
Some lenders send transition notices 3–6 months in advance. Review your original loan documents so the date is not a surprise.
How can you prepare for the repayment period?
There are several ways to manage the transition well:
- Pay down principal early. Any voluntary principal payments during the draw period directly reduce the balance you will be repaying — and the monthly payment you face.
- Budget for higher payments. Model your repayment-period payment in advance using your current balance and the remaining loan term.
- Consider refinancing. As the draw period winds down, some homeowners refinance the HELOC into a fixed-rate home equity loan for payment predictability.
- Watch your variable rate. Because most HELOCs are variable, your repayment payment can still move after the transition. A rising rate environment raises both your draw-period interest cost and your repayment payment.
Does every HELOC follow a 10/20-year structure?
The 10-year draw / 20-year repayment split is common but not universal. Some lenders offer:
- 5-year draw / 10-year repayment — shorter total term, faster payoff
- 10-year draw / 10-year repayment — 20-year total term
- Balloon HELOCs — the full balance is due as a lump sum at the end of the draw period (less common today)
Always confirm the exact term structure with your lender before signing. The differences in payment timing and total interest cost can be significant.
Why does the structure matter for your planning?
A HELOC is a powerful tool when you understand the full arc of the product. Homeowners who treat the draw period as “cheap money forever” can be caught off guard when the repayment period arrives. Those who plan ahead — tracking their balance, modeling future payments, and optionally reducing principal early — use the product as it was designed: flexible access during the draw phase, disciplined payoff during repayment.
If you are comparing a HELOC to a home equity loan or other options, the two-phase structure is one of the key factors to weigh alongside interest rate type, closing costs, and your specific borrowing timeline.
