What this credit card payoff calculator does
Credit card interest compounds against you every single month, so two cards with the same balance can cost wildly different amounts depending on your APR and how much you pay. This calculator removes the guesswork. Enter your balance, your card's APR, and either the amount you can pay each month or the date you want to be debt-free — and it shows your payoff timeline, the total interest you'll hand the bank, and the total you'll actually pay.
It uses the same month-by-month amortization math your card issuer uses: each month, interest is charged on the remaining balance first, and whatever is left of your payment reduces the principal. That's why paying just a little extra early makes such a big difference.
How to use it
- Balance — the current amount owed on the card.
- APR — your card's annual percentage rate, printed on your statement (US cards average roughly 20–24%).
- Choose a mode: use By monthly payment to see how long a set payment takes, or By target date to find the monthly payment required to be free by a certain number of months.
A worked example
Say you owe $5,000 at a 22% APR and pay $250 a month. This calculator shows it takes about 26 months and roughly $1,286 in interest — so you'll pay back around $6,286 in total.
Now bump the payment to $400 a month. You're debt-free in about 15 monthsand pay closer to $732 in interest — cutting both your payoff time and your interest almost in half. Try it above: small changes to the monthly payment have an outsized effect because less time in debt means less compounding.
Tips to pay off your card faster
- Always beat the minimum. Minimum payments are designed to keep you in debt for years — pay a fixed higher amount instead.
- Ask for a lower APR. A single phone call can reduce your rate; even a few points saves real money.
- Consider a 0% balance transfer if you qualify, and clear the balance before the promo period ends.
- Pay biweekly. Splitting your payment in two and paying every two weeks squeezes in an extra payment each year.
- Stop adding new charges to the card while you're paying it down.
