The single biggest surprise in home equity lending is the HELOC draw period vs repayment period switch — the day a line of credit stops behaving like a credit card and starts behaving like a mortgage. This guide explains what changes, why the payment can climb, and what homeowners typically look at before the transition arrives. It is educational only. Remember throughout that a HELOC is secured by your home.
How the draw period works
During the draw period you can borrow, repay, and borrow again up to your credit limit. Companies commonly advertise draw periods of around ten years, though the length varies.
- Many lines require only interest-only HELOC payments during this phase, which keeps the monthly cost low.
- The rate is usually variable, so even an interest-only payment moves when the index moves.
- Because principal is optional, balances often sit untouched for years.
For how the line compares with a lump-sum product, see home equity loan vs HELOC and the home equity borrowing hub.
What changes in the repayment period
At the end of the HELOC draw period, the line closes to new borrowing. Whatever you owe amortises over the remaining term — often fifteen to twenty years, though this varies by company. Payments now cover principal plus interest, and you cannot re-borrow what you pay down.
Why payments can rise at the transition
HELOC payment shock comes from two changes landing at once: principal enters the payment, and the repayment window is shorter than a fresh 30-year mortgage. A balance that cost only interest for a decade suddenly has to be retired in half the time. If the variable rate has also risen, the jump is larger again.
Planning ahead of the draw-period end
Homeowners typically start looking a year or two out:
- Pay principal during the draw period so less remains to amortise.
- Ask whether your company offers a fixed-rate lock on part of the balance — see fixed-rate HELOCs.
- Ask whether the line can be renewed, refinanced, or replaced with a new product. Availability is never guaranteed and depends on credit, income, and your home's value at the time.
- Model the amortising payment now, not when the letter arrives.
What to compare when shopping a HELOC
- The length of both phases, stated in years.
- Whether draw-period payments are interest-only or include principal.
- Any rate cap on the variable rate, lifetime and periodic.
- Whether a fixed-rate conversion option exists and what it costs.

Frequently asked questions
How long is a HELOC draw period?
Companies commonly advertise draw periods of about ten years, followed by a repayment period often running fifteen to twenty years. Both lengths vary by company and product, so check the exact figures in your agreement rather than assuming a standard.
Why did my HELOC payment go up so much?
Most likely the draw period ended, so principal joined the payment and the balance now has to be repaid over a shorter term. A rise in the variable rate can add to the increase. Your loan documents state the transition date.
Can I extend a HELOC draw period?
Some companies allow a renewal, refinance, or replacement line, but none of this is guaranteed. Approval depends on credit, income, and your home's value at the time. Ask your servicer well before the draw period ends.
