HELOC Draw Period vs. Repayment Period: What Actually Changes

A HELOC gets sold on its first half. You are approved for a credit line, you draw what you need, and the payment is small — sometimes only interest. That is the draw period, and it is the part most homeowners understand.

The second half is a different loan wearing the same name. Borrowing stops, principal becomes mandatory, and the balance has to be cleared on a schedule that is usually much shorter than a mortgage. Nobody shops for that half. You inherit it, on a date that was written into your paperwork years earlier.

Here is exactly what changes, what it does to the payment, and which lines in your documents decide how hard the transition lands.

Quick summary: The draw period lets you borrow. The repayment period does not. When it flips, principal payments start, the clock gets short, and the Consumer Financial Protection Bureau notes that monthly payments are often significantly higher. Some plans skip the schedule entirely and demand the whole balance at once.

What the Draw Period Actually Gives You

During the draw period you can generally spend up to your credit limit whenever you want. The CFPB uses 10 years as a typical example, though plans vary. Some plans add conditions people forget about: a minimum amount per draw, a minimum balance you have to keep outstanding, or a required initial draw when the line is opened.

Payments during the draw come in two flavors. Some plans set a minimum monthly payment that includes a portion of principal plus accrued interest — but the CFPB is blunt that the portion going toward principal typically does not repay the principal by the end of the term. Other plans allow interest-only payments, which means you pay nothing toward the balance at all.

Either way, the rate is almost always variable. A HELOC rate is an index plus a margin, and common indexes include the U.S. prime rate and the Constant Maturity Treasury rate. The Wall Street Journal prime rate stood at 6.75% as of August 18, 2026. On a $150,000 balance, a one-point move in the index changes an interest-only payment by about $125 a month — before the repayment period does anything at all.

What Flips When the Repayment Period Starts

Three things change on the same day:

You stop being able to borrow. The line closes for new draws. Whatever you had planned to fund with it later, you now need another source.
Principal becomes mandatory. Whether you paid some, a little, or none of it during the draw, the full balance now has to come down.
The clock gets short. The CFPB says the lender may set a schedule to repay the full amount, often over ten or 15 years — not the 30 you are used to thinking in.

What That Does to the Payment

The table below assumes a $150,000 balance carried into repayment at a 7.75% APR — prime at 6.75% plus an illustrative one-point margin — with interest-only payments during the draw. Margins vary by lender, credit profile, and loan size, so treat this as arithmetic, not a quote.

Stage	Monthly payment	Change
Interest-only, during the draw	$969	—
Repayment over 20 years	$1,231	▲ +$262
Repayment over 15 years	$1,412	▲ +$443
Repayment over 10 years	$1,800	▲ +$831

Nothing about the borrower changed. The rate did not move. The only variable is how many years the plan gives you to clear the balance, and a 10-year schedule nearly doubles the payment against interest-only. That is the whole surprise, and it is entirely predictable years in advance.

One more detail: unless your plan converts you to a fixed rate, the repayment period is still variable. You are now amortizing principal and carrying rate risk at the same time.

The balloon case: Some plans do not amortize at all. The CFPB warns that you may have to pay the entire balance owed all at once — a balloon payment — and that you must be prepared to make it by refinancing with the lender, getting a loan from another lender, or some other means. If you cannot pay it in full, you could lose your home. Find out which kind of plan you have before you need to know.

The Lines in Your Paperwork That Decide All of This

Lenders are required to disclose the terms and costs of a HELOC, including the annual percentage rate, information about variable rates, payment terms, transaction requirements, annual fees, and other charges. You usually get those disclosures with the application, plus more before the line is opened. Federal law also gives you three days to cancel a newly opened line in writing.

The CFPB's own HELOC shopping worksheet points at the specific items worth reading twice:

Length of plan — the draw period and the repayment period, stated separately
Balloon repayment of full balance owed? — yes or no changes everything above
Interest rate cap and floor — your ceiling if the index climbs
Conversion to a fixed-term loan? — whether you can lock part of the balance
Renewal available? Refinancing of balance by lender? — your exits at the deadline

If you already have a HELOC, those answers are in the documents you signed. Ten minutes now beats finding out from a statement.

Your Options Before the Deadline — and Why Lead Time Matters

Reaching the end of a draw period is not a trap, as long as you are early. The realistic paths:

Convert part of the balance to a fixed rate. Many plans allow it. The CFPB notes the fixed rate is typically higher than the variable one, but it buys predictable payments.
Refinance the second lien. A new HELOC restarts a draw period; a fixed home equity loan trades flexibility for a set payment. Our breakdown of home equity loan vs. HELOC covers which fits which situation.
Pay it down during the draw. Every dollar of principal retired before the flip is a dollar that never enters the shorter schedule.
Consider a cash-out refinance only if your first mortgage is expensive. With the 30-year fixed averaging 6.65% as of August 20, 2026, a homeowner sitting on a 3.25% first mortgage would be trading a cheap loan for a costly one to solve a second-lien problem. Homeowners at 7%+ are in a different position — the comparison is in HELOC vs. cash-out refinance.

All of these are underwritten on your equity, credit, and income at the time you apply — not the profile you had when the line was approved. That is the argument for starting roughly a year out rather than in the final month.

The Freeze Most People Don't Plan For

There is one more reason not to leave this to the last minute. HELOCs generally permit the lender to freeze or reduce your credit line if your home's value falls or your financial situation changes for the worse, according to the CFPB. A line you are counting on as an emergency fund is not the same thing as cash in an account, and a strategy built on drawing heavily right before the deadline can fail on someone else's timing.

If your line does get frozen, the CFPB's suggestions are to ask the lender why — sometimes it traces to a credit report error or a stale valuation — and to shop for another line elsewhere.

Where a Broker Is Useful Here

A bank can only offer you the terms on its own shelf. A broker can compare draw and repayment structures across multiple lenders, which matters more on a HELOC than on a first mortgage because the repayment terms differ so much between plans. That difference is exactly what our comparison of a mortgage broker vs. a bank gets at.

And if your first mortgage is a low pre-2022 rate, the reason to solve this on the second lien is the same reason you took a HELOC in the first place — the logic is laid out in accessing equity without refinancing. If you work for a large California employer, it is also worth checking whether a relationship-based discounted rate is available to you before you shop retail.

Frequently Asked Questions

What is the difference between the draw period and the repayment period on a HELOC?

The draw period is the stretch when you can borrow against the line, spending up to your credit limit as needed; the CFPB notes it could last 10 years, for example. When it ends you enter the repayment period, where you can no longer borrow and the lender sets a schedule to repay the full balance, often over ten or 15 years. Borrowing stops, principal becomes mandatory, and the term is usually shorter than the one your first mortgage runs on.

Does my HELOC payment go up when the draw period ends?

Usually, and often by a lot. The CFPB states that monthly payments are often significantly higher once you enter repayment. The size of the jump depends on how much principal you were paying during the draw and how many years the repayment schedule runs. On a $150,000 balance at an illustrative 7.75% APR, an interest-only draw payment of about $969 becomes roughly $1,412 on a 15-year repayment schedule and about $1,800 on a 10-year one.

What is a HELOC balloon payment?

Instead of an amortizing schedule, some plans require the entire balance owed at the end of the draw period, all at once. The CFPB describes this as a balloon payment and warns you must be prepared to make it by refinancing with the lender, getting a loan elsewhere, or other means, and that failing to pay it in full could cost you your home. Whether your plan has one is disclosed in your HELOC paperwork.

Can I refinance or extend my HELOC before the repayment period starts?

Often yes, and it is far easier before the deadline than after. Options can include converting some or all of the balance to a fixed rate if your plan allows it, refinancing the second lien into a new HELOC or a fixed home equity loan, or paying the balance down during the draw. Each depends on your equity, credit, and income at the time you apply, so give it lead time rather than starting the month the draw ends.

Can my lender freeze my HELOC before the draw period ends?

Yes. The CFPB notes that HELOCs generally permit the lender to freeze or reduce your credit line if the value of your home falls or if your financial situation changes for the worse. That is why treating an open line as a guaranteed emergency fund is risky, and why a plan that depends on drawing more right before the deadline can fail.
