About the Credit Card Calculator

good long-tail opportunity

The Credit Card Calculator is a free online financial tool designed to help you calculate how long it will take to pay off your credit card balance and how much interest you will pay along the way. It uses a daily-rate iterative simulation to accurately project month-by-month payoff progress. Pair it with our Loan Calculator for debt consolidation comparisons or our Compound Interest Calculator to see how much you could save by investing instead.

Enter your current balance, APR, and monthly payment to get your payoff timeline, total interest, and total amount paid. Use the Accelerate panel to see how an extra monthly payment shortens your payoff and saves interest, or use the Payoff Goal panel to calculate the payment needed to be debt-free by a target month. A full month-by-month payoff schedule shows every payment, principal, and interest charge.

Formulas & Mathematical Theory

Daily Interest Rate

rdaily=APR365r_{\text{daily}} = \frac{\text{APR}}{365}

The annual percentage rate divided by 365 gives the daily periodic rate used in credit card interest calculations.

Credit Card Payoff Time

n=log⁡(MM−B×rdaily)log⁡(1+rdaily)n = \frac{\log\left(\frac{M}{M - B \times r_{\text{daily}}}\right)}{\log(1 + r_{\text{daily}})}

Where B is the current balance, M is the monthly payment, and r\_daily is the daily interest rate. The formula solves for the number of days to full payoff.
