HELOC Repayment Period Starts: What Changes and Why

TL;DR: Most HELOCs give you a 10-year draw period where you pay interest-only, followed by a 15- or 20-year repayment period where principal gets added in. That switch can raise your monthly payment by 50% to 100% or more, especially if your rate is also variable. Check your loan documents now for the exact draw-period end date and start planning at least 12 months ahead.

You've been paying interest-only on your HELOC for years, and the bill has stayed manageable. Then one statement shows a payment that's nearly double what you're used to, and there's no warning label explaining why. Here's what's actually happening and what to do before it catches you off guard.

Okoniq Property Hub tracks your loan dates and balances in one place, so you can see your draw-period end date and repayment schedule before the payment jump hits your bank account.

What actually changes when the draw period ends?

Two things change at once: you can no longer borrow against the line, and your payment starts including principal. During the draw period, which is typically 10 years, most HELOCs let you make interest-only payments on whatever you've borrowed. Once repayment begins, usually for 15 or 20 years, the lender recalculates your payment to fully amortize the outstanding balance over the remaining term.

Say you owe $60,000 on a HELOC at 8% interest. Interest-only, that's $400 a month. Once repayment starts and the balance amortizes over 20 years at the same rate, the payment jumps to roughly $502. If your rate is variable and climbs another point or two, that number climbs further. This is the same math that governs how your amortization schedule works on a regular mortgage, except here it lands on you all at once instead of from day one.

Why does the payment jump so much?

The jump happens because you've been paying zero principal for a decade, and the lender now has far less time to collect it. A 20-year repayment period sounds long, but compared to the 30-year amortization most people are used to on a first mortgage, it compresses the same principal into a shorter window. Add a variable rate that's moved up since you opened the line, and the combination can push payments up 50% to 100% compared to what you paid during the draw period.

This is different from a home equity loan, which amortizes from the start and never has this cliff. If you're deciding between the two products, home equity loan vs HELOC breaks down which one avoids payment shock and which one gives you more flexibility upfront.

What are your options before repayment starts?

You have four real options, and each works better depending on your balance and rate: pay down the balance aggressively during the draw period, refinance into a fixed home equity loan, do a cash-out refinance on your first mortgage to fold the HELOC in, or negotiate a renewal or extension of the draw period with your lender.

| Option | Best for | Trade-off | |---|---|---| | Pay down balance early | Owners with spare cash flow | Ties up money you could invest elsewhere | | Refinance into fixed loan | Owners who want payment certainty | Closing costs, new rate lock | | Cash-out refinance | Owners with a low first-mortgage rate they're willing to give up | Resets your whole mortgage term | | Draw period extension | Owners who need more time, good credit | Not guaranteed, lender's discretion |

If you're weighing a cash-out refinance against keeping the HELOC separate, HELOC vs cash-out refinance walks through the math on rate resets and closing costs. And before committing to any refinance, run the numbers through a 60-second break-even calculation to see how many months it takes to recover the closing costs.

How do you avoid payment shock down the line?

The single best move is checking your draw-period end date today, not the month before it arrives. That date is printed on your original HELOC agreement and usually shows up on your monthly statement in the months leading up to conversion. Mark it on a calendar 12 to 18 months out and use that window to either pay down principal or line up refinancing options while your credit and equity position are strong.

It also helps to stress-test your budget against a doubled payment now, while you have time to adjust, rather than after the new bill arrives. If that stress test shows a gap, this is exactly the kind of situation a homeowner emergency fund is built for, covering the first few months of a higher payment while you sort out a longer-term fix.

What if you're already in the repayment period and struggling?

Call your lender before you miss a payment, not after. Lenders have more flexibility to modify terms, extend the amortization period, or temporarily adjust payments for someone who's current and asking ahead of trouble than for someone already 60 days behind. A short hardship conversation now beats a credit hit and collections process later. If a rate reset is part of the problem, ask specifically whether they'll let you convert the remaining balance to a fixed rate. It's not automatic, but it costs nothing to ask, and lenders sometimes have retention programs for exactly this scenario.

FAQ

How long is a typical HELOC repayment period?

Most HELOCs have a 15- or 20-year repayment period following a 10-year draw period, though some lenders use 5-year draws with 10- or 15-year repayment terms. Check your original loan agreement for the exact numbers, since they vary by lender.

Can I still borrow from my HELOC once repayment starts?

No. Once the draw period ends, the line closes for new borrowing and you can only pay down the existing balance. Any remaining available credit disappears at that point.

Will my HELOC payment definitely increase?

In most cases yes, because principal gets added to what was previously an interest-only payment. The size of the increase depends on your balance, remaining term, and whether your rate is fixed or variable, but a 50% to 100% jump is common.

Can I refinance a HELOC that's already in repayment?

Yes, you can refinance a HELOC in repayment into a new fixed-rate home equity loan, roll it into a cash-out refinance of your first mortgage, or in some cases get a new HELOC to pay off the old one. Each option resets fees and terms, so compare closing costs against your remaining balance before committing.

Does paying extra during the draw period actually help?

Yes, every dollar of principal paid during the draw period reduces the balance that gets amortized once repayment starts, which lowers your future payment directly. Even modest extra payments in years 8 through 10 of the draw period can meaningfully soften the jump.
