Credit Card Payoff Calculator

How long your balance takes to clear and what the interest costs, comparing minimum payments against a fixed amount month by month.

The short answer

A $6,500 balance at 22.9% APR paid at $300 a month clears in 29 months and costs $1,968 in interest. Paying only the minimum on the same balance takes 21 and a half years and costs $11,316, nearly six times as much.

Minimum payments versus a fixed amount

Same balance, same rate. The only difference is whether the payment shrinks with the balance.

Interest is charged on the balance each month at one twelfth of the APR, then your payment is applied.

monthly rate = 22.9% ÷ 12 = 1.9083%
month 1 interest = $6,500.00 × 0.019083 = $124.04

Where this is a simplification

It assumes you stop spending on the card, that the rate never changes, and that no annual fee, late fee or cash-advance rate applies. Issuers also compound daily rather than monthly, which makes real interest slightly higher than shown.

Questions

What people ask

Why do minimum payments take so long?

Because the minimum is calculated from the balance, so it shrinks as the balance does. Interest is charged first and what is left over goes against the debt. Early on that leftover is small, and it gets smaller every month you make progress.

Is it better to pay the highest rate first or the smallest balance first?

Paying the highest rate first (the avalanche) always costs less interest. Paying the smallest balance first (the snowball) clears individual cards sooner, which some people find easier to stick with. The cheapest plan is only cheaper if you actually follow it.

Should I move the balance to a 0% card?

It usually helps, but check the transfer fee, typically 3% to 5% of the balance, and whether you can clear the debt before the promotional rate ends. Run this calculator at 0% for the promo months, then at the go-to rate for the remainder.

Why is my real interest slightly higher than this shows?

Issuers compound daily on the average daily balance; this calculator compounds monthly. Over a long payoff the difference is real but small, usually a percent or two of the total interest.
