What is a HELOC draw period and how does it work?

The draw period is the first phase of a HELOC, usually about 10 years, during which you can borrow from your credit line as you need and often pay interest only on what you use. When it ends, you can no longer draw, and you enter the repayment period where you pay back principal and interest, which usually raises your payment.

Understanding this two-phase structure is the key to avoiding a payment shock later. The low payment during the draw period is not the payment you keep forever.

How does the draw period work?

During the draw period you have access to your full credit line. You can borrow, repay, and borrow again, and you pay interest only on the balance you have used, not the whole limit. Many lenders set a minimum payment during this phase that covers just the interest, which keeps early payments low.

How long is a HELOC draw period?

Ten years is the most common length, though it varies by lender and product. Some run shorter or longer. Your specific term is set in your HELOC agreement, so check the document for the exact draw and repayment lengths.

What happens when the draw period ends?

You lose the ability to draw new funds, and the repayment period begins. Your payment changes from interest only to principal and interest, spread over the remaining term, often up to 20 years. Because you are now paying down principal too, the payment usually jumps, sometimes sharply.

Why does my payment jump after the draw period?

Two forces combine. You start repaying principal instead of interest alone, and if your rate rose during the draw period, that adds to it. A balance that felt cheap on interest-only payments can become a much larger bill once principal is folded in. As Emmett Clark, licensed in 18 states with access to more than 240 wholesale lenders, I help borrowers plan for this shift before it arrives, whether by paying down principal early or refinancing ahead of the change.

Can I avoid the payment jump?

You have options. You can pay down principal during the draw period so less remains when repayment starts, or you can refinance the HELOC before the draw period ends, covered in can you refinance a HELOC. Planning ahead is easier than reacting once the higher payment hits.
