Your monthly payment must exceed the interest-only amount to make progress on the principal. If your payment equals or is less than the monthly interest charge, the balance will never reduce.

Why Knowing Your Payoff Date Matters

Many HELOC borrowers focus only on the monthly payment and never calculate how long it will actually take to clear the balance, or how much interest they'll pay in total. The payoff calculator above makes both of those figures visible instantly.

The Danger of Interest-Only Payments

During the draw period, most lenders only require interest-only minimum payments. This keeps payments low but means your balance never reduces. If you carry a $35,000 balance at 8.5% and only pay the monthly interest of around $248, your balance at the end of the draw period will be exactly the same as when you started — and you'll then face full amortizing payments in the repayment period on the full outstanding amount.

Repayment period payment shock

Homeowners who make only minimum interest payments during the draw period are often caught off guard when the repayment period begins and their monthly obligation jumps significantly. Use the HELOC Payment Calculator to model what your repayment period payment would look like.

How Extra Payments Help

Even modest additional payments above the interest-only minimum can dramatically shorten your payoff timeline and reduce total interest paid. Try adjusting the monthly payment figure in the calculator above to see the impact — the difference between paying $400 and $600 per month on a $35,000 balance is often several years and thousands of dollars in interest.

Next Steps

If your payoff timeline feels too long, consider whether consolidating or refinancing makes sense. Our HELOC vs. Home Equity Loan Calculator can help you compare a fixed-rate option that forces principal paydown from day one.

HELOC Payoff FAQs

If your payment equals or is less than the monthly interest charge, your balance will never go down — it may even increase. Always ensure your payment exceeds the interest-only amount by a meaningful margin to make actual progress on the principal.

Yes. Most HELOCs allow extra or lump-sum payments at any time without penalty, which directly reduces your principal balance and shortens your payoff timeline. Always check your specific loan agreement for any prepayment restrictions.

Yes. Because HELOCs carry variable rates, a rate increase means more of each payment goes to interest, extending your payoff timeline. Re-run this calculator if your rate changes to get an updated estimate.
