Credit Card Payoff Calculator
Enter your balance, interest rate and monthly payment to see how long payoff will take and the total interest you'll pay.
How it's calculated
This runs a month-by-month simulation: each month, interest is charged on the remaining balance, the rest of the payment goes to principal, and the process repeats until the balance reaches zero — the same way real credit card amortization works.
Frequently asked
Why does it say "Never" for my payment?
That means your monthly payment doesn't even cover the interest charged that month, so the balance would grow rather than shrink. You'd need to increase the payment above the monthly interest amount just to make progress.
Does this assume the balance stays fixed?
Yes — it assumes no new charges are added and the same payment is made every month. Adding new purchases to the card will extend the payoff time beyond what's shown here.
