What the Credit Card Calculator actually does.
Our free Credit Card Calculator shows you exactly how long it will take to pay off a balance and how much you'll spend in interest along the way. Enter your balance, APR, and monthly payment, and the tool does the rest — no sign-up, no email, no paywall.
Most people underestimate what minimum payments actually cost. A $5,000 balance at 24% APR paid at the minimum can take over 20 years to clear. This calculator lets you test different monthly amounts so you can see how even an extra $50 or $100 a month changes the math.
Enter your balance and
payment to see results.

Common questions about this tool.
How accurate is this credit card calculator?
+−
It uses the standard amortization formula banks use to charge interest. Results match lender statements within a few dollars for most balances. Exact outcomes can vary if your APR changes mid-cycle or if your card uses a different interest calculation method.
What APR should I enter?
+−
Use the 'Purchase APR' shown on your most recent credit card statement. If you have a promotional rate that expires soon, use the post-promo APR for a realistic long-term view.
Should I pay off debt or invest first?
+−
As a rule of thumb, any debt with an interest rate higher than ~7–8% is worth prioritizing over investing. Credit card APRs are almost always in that range, so pay the card down first. Our team can help you model your specific situation.
