Debt payoff toolkit
This credit card payoff calculator turns three numbers, balance, APR and monthly payment, into your debt free date and total interest, with every step of the math shown. Type a bigger payment and watch years of interest disappear.
Estimates only. Not financial advice. This calculator runs entirely in your browser and nothing you type leaves your device.
Three numbers run the whole show: your balance, your APR, and the fixed amount you pay each month. Every simulated month, interest accrues first (balance times APR divided by 12), then your payment lands and the balance drops. The calculator repeats this until the balance hits zero, counting months and adding up every dollar of interest along the way. No new charges, no fees, constant payment: the cleanest possible picture of your payoff.
Take the numbers prefilled above: an $8,500 balance at 24.99% with a $250 monthly payment. The credit card payoff calculator says 5 years, $6,433.86 in interest, $14,933.86 total. Read that again: you repay almost 76% extra on top of what you borrowed. Now raise the payment to $400: 2 years and 5 months, $2,841.40 in interest. An extra $150 a month erases $3,592.46 of interest and finishes 2 years and 7 months sooner. That is the entire game in one comparison.
Use it before every payoff decision. Wondering whether a balance transfer beats grinding it out? Run both. Deciding between the debt snowball and attacking the highest rate card first? This calculator gives you the single card truth; the snowball calculator scales it to all your debts. The pattern across every scenario is the same: the payment size matters more than anything else. Pick the biggest fixed payment you can sustain, automate it, and stop adding new charges.
Enter your balance, APR and the fixed amount you will pay each month. The calculator simulates month by month: interest accrues on the balance, then your payment lands. It counts the months, adds up the interest, and shows your debt free date. The math assumes no new charges and a constant payment.
Enter what you actually plan to pay, not the minimum printed on your statement. The minimum keeps you in debt for years; this calculator shows what a fixed, intentional payment does. Try your minimum first, then try $50 or $100 more and watch the timeline collapse.
Because your payment does not cover the monthly interest. On an $8,500 balance at 24.99%, the first month interest alone is about $177. Pay $150 and the balance grows every month, forever. Raise the payment above the monthly interest and the calculator will show a finish date.
Attack one card at a time. Minimums everywhere, then every extra dollar at a single target until it is gone. Our debt snowball calculator runs this on up to four debts at once and shows the payoff order.
No, and that is deliberate. New charges while paying down are the classic plan killer: every new dollar restarts part of the clock. Freeze the card (stop using it, not necessarily closing it) while you pay it off, and the calculator timeline is the timeline you will actually live.
