Debt Payoff Calculator

See how long it takes to clear a debt, how much interest you'll pay, and how much paying a little extra each month could save you.

Example scenarios

Enter a balance, interest rate, and monthly payment to see your payoff timeline.

Juggling more than one debt? This calculator handles a single balance. Two popular multi-debt strategies are the snowball (smallest balance first) and avalanche (highest rate first).

Knowing the date is one thing. Hitting it is another.

Future Map turns your payoff goal into a plan with checkpoints and reminders, so you stay on pace month after month.

Frequently asked questions

How does this debt payoff calculator work?
It takes your current balance, annual interest rate (APR), and fixed monthly payment, then applies interest month by month until the balance reaches zero. The result shows how many months it takes and the total interest you pay along the way.
Why won’t my debt ever get paid off?
If your monthly payment is less than or equal to the interest charged each month, the balance never shrinks — it can even grow. The calculator warns you when this happens and shows the minimum payment needed just to cover interest.
What is the difference between the snowball and avalanche methods?
With the snowball method you pay off the smallest balance first for quick, motivating wins. With the avalanche method you pay off the highest interest rate first, which saves the most money over time. Both work — the best one is the one you will stick with.
Does paying more than the minimum help?
Yes. Because interest is charged on the remaining balance, every extra dollar you pay reduces both the time to payoff and the total interest. Even small increases to your monthly payment can shave months off the timeline.
