HELOC Loan Payoff Calculator

A $40,000 HELOC balance at 9% paid at $600 a month is gone in 7 years 9 months and costs $15,660 in interest. Paying $800 ends it in 5 years 3 months.

Enter your own balance, rate and payment, then read the tables for what a different payment or rate does.

HELOC loan payoff calculator

Paid off in 7 years 9 months (93 payments).

Interest over that time: $15,660. Total paid: $55,660.

A bigger payment on the same balance

The line is $40,000 at 9%. One month of interest is $300.00, so any payment above that lowers the balance.

The same $600 payment at three rates

A HELOC rate can move, so run the calculator again with a higher rate to see how far the payoff date slips.

How the calculator works

  1. Each month, interest = balance x rate / 12.
  2. The payment minus that interest comes off the balance.
  3. The count stops when the balance reaches zero. Interest is the sum of every month's interest.

It treats the balance as one fixed-rate loan with no new draws. For the interest-only draw payment and the payment in repayment see the HELOC monthly payment calculator, and for a fixed-rate equity loan the home equity loan payoff calculator.

Before the draw period ends

The CFPB says that after the draw period ends you stop being able to borrow from your HELOC and enter the repayment period.

The CFPB says monthly payments are often significantly higher once you enter repayment.

Check your agreement for the end date of the draw period, then enter the repayment payment above to see the payoff date.

Frequently asked questions

How do I use this calculator?

Enter the balance you owe on the line, the current rate and the amount you pay each month. The result is the number of payments until the balance is zero and the interest over that time.

What if my payment is only the interest?

An interest-only payment never lowers the balance. On $40,000 at 9% it is $300.00 a month, and the calculator says so when your payment is that low.

Does the calculator add new draws?

No. It assumes you borrow nothing more and the rate stays fixed. Every new draw adds to the balance and moves the payoff date out.

What happens when the draw period ends?

Your payment changes to a repayment schedule. Use the HELOC monthly payment calculator to see the new payment, then enter it here to check the payoff date.

How do I get the payoff time in a spreadsheet?

Use NPER(rate/12, -payment, balance). It returns the number of months. Divide by 12 for years.
