Free, accurate debt calculators built for real people paying off real credit card debt.
CreditCardPayoffCalc.info provides a suite of free, browser-based calculators to help US consumers understand, plan, and execute a credit card debt payoff strategy. Every calculation runs entirely in your browser — no data is sent to any server, ever.
The average American household carries over $6,500 in credit card debt at an average APR of 22%. The interest on that balance costs roughly $1,430 per year — about $119 every month just to stand still. Our goal is to make it dead simple to see exactly what you're paying, what it will cost you if you change nothing, and what paying an extra $50, $100, or $200 per month actually does to your timeline and total cost.
Every calculator on this site uses standard consumer finance formulas — the same math used by credit card issuers themselves:
All formulas are documented in the Methodology section on each calculator page. We don't round or fudge numbers to look more impressive — you'll get the same result as a spreadsheet built from scratch.
No account. No email. No tracking of the numbers you enter. The calculators are entirely client-side JavaScript — your balance, APR, and payment amounts never leave your device. The only third-party code on this site is Google AdSense (display ads) and Google Fonts. See our Privacy Policy for full details.
