Credit Card Calculator

Estimate how long a credit card balance may take to repay, how much interest accrues and whether your payment covers interest plus principal.

This is an estimate. Card issuers can use different minimum-payment formulas, fees, promotional rates and daily balance methods.

How to read the payoff estimate

The calculator applies a monthly APR rate to the remaining balance, adds monthly charges and a monthly share of any annual fee, then subtracts your payment. If the payment does not reduce principal, the page warns that the balance may not be paid off under the entered assumptions.

Example

With a $5,000 balance at 21.99% APR and a $250 monthly payment, part of the first payment goes to interest before principal falls. Adding new monthly charges can make the payoff much slower or prevent payoff entirely.

Common mistakes

Do not assume paying the minimum means the balance is moving quickly. If the payment barely exceeds interest and fees, payoff can take much longer than expected.

Minimum payment caveat

The displayed minimum payment is a simplified estimate using the greater of a percentage of balance or a payment floor. Real issuers may add interest, fees, past-due amounts or other rules, so your statement can differ from this estimate.

Limitations

This is not a statement, payoff quote or credit advice. Promotional APRs, daily balance methods, late fees, penalty rates and issuer-specific rules are not included.
