Introduction

Cards charge daily periodic interest on revolving balances. Paying only the minimum extends payoff for years and multiplies interest versus paying a fixed higher amount.

Credit Card Interest

Cards charge daily periodic interest on revolving balances. Paying only the minimum extends payoff for years and multiplies interest versus paying a fixed higher amount.

Pay a Fixed Amount

Enter balance, APR, and monthly payment to see payoff month, total interest, and comparison against an estimated minimum-payment path.

Payoff by Date

Set a target payoff date and the calculator solves for the required monthly payment—useful for debt-free goals tied to a calendar.

Quick-Fill Payments

Links set payment to monthly interest plus 1-5% of balance—common advisor heuristics for accelerating payoff without guessing.
