Credit Card Payoff Calculator

See how a fixed monthly payment may affect payoff time, total interest and the total amount repaid.

This assumes no new purchases, late fees, annual fees or APR changes and applies one payment each month.

How this payoff estimate works

The calculator applies one month of interest to the remaining balance and then subtracts the payment. It repeats the process until the estimated balance reaches zero. Actual issuers often calculate interest using an average daily balance, so statement results may differ.

Ways to reduce the projected interest

  • Stop adding new purchases to the payoff balance.
  • Pay more than the required minimum when possible.
  • Apply windfalls directly to principal.
  • Compare a lower-rate option only after including every fee.

Build a credit-card payoff plan that accounts for interest

Credit-card interest is commonly calculated from a daily or monthly periodic rate, while minimum payments may decline with the balance. Paying only a changing minimum can extend repayment. A fixed payment above the minimum usually makes the payoff date easier to understand and can reduce interest.

How to use this page

The calculator applies the entered APR to the remaining balance, subtracts the planned monthly payment and repeats until the balance reaches zero. It reports estimated payoff time and interest under the simplified assumption of no new purchases, fees or APR changes.

Practical exampleCompare the current payment with a payment that is $50 or $100 higher. The difference in payoff months and total interest helps quantify the value of directing extra cash to the balance.

Inputs to verify

  • Stop adding purchases to the balance being modeled.
  • Confirm whether the account has multiple APR categories.
  • Keep at least the required minimum payment automated to avoid late fees.

Common questions

Why can a small payment fail?

If the payment does not exceed interest and fees, the balance may decline very slowly or grow.

Should I pay the highest APR first?

The avalanche strategy prioritizes the highest APR, while the snowball strategy prioritizes the smallest balance. The best plan is one you can sustain.
