Credit Card Payoff Calculator

How credit card payoff really works

Credit card interest compounds monthly, so the APR you see is charged on the balance every single month. A typical minimum payment is just the month’s interest plus about 1% of the balance (never less than a small floor like $25), so it barely dents the principal and most of your money goes to interest. Because the minimum shrinks as the balance shrinks, the payoff stretches out for many years and you can pay a large share of the balance again in interest. This calculator shows that path next to a fixed monthly payment so the difference is impossible to miss.

A fixed payment is the single most powerful lever you have. Paying a steady amount each month — instead of a minimum that keeps dropping — means every extra dollar attacks the principal, and the balance falls faster each month as less of your payment is eaten by interest. Raising the payment even modestly can cut years off the payoff and save thousands in interest. The calculator reports exactly how much time and interest your chosen payment saves compared with the minimum.

Two warnings the tool makes explicit. First, if your payment is smaller than the monthly interest, the balance grows no matter how long you pay — a real trap on high-APR cards. Second, on a high enough APR a low minimum payment may never clear the balance at all. If you are carrying a balance across several cards, pair this with a debt payoff strategy that orders them by rate or balance. Treat the result as an estimate: real statements vary with the exact minimum-payment formula, fees, and any new charges you add.
