Credit Card Payoff Calculator

Enter your current credit card balance — the total amount you owe. Next, enter your card's APR (Annual Percentage Rate), which you can find on your statement or online account. Finally, set the monthly payment amount you plan to make.

The calculator instantly shows how many months until you're debt-free, the total interest you'll pay, and provides a month-by-month payment schedule. If your payment is too low to cover monthly interest, you'll see a warning with the minimum required payment.

Experiment with different payment amounts to find the payoff timeline that works for your budget. The charts show your balance declining over time and how much interest you pay each year. Export the schedule to CSV for your financial records.

Credit card payoff calculations work differently from standard amortizing loans. With a fixed monthly payment, each month the algorithm first charges interest on the remaining balance, then applies the rest of your payment to the principal.

Monthly Interest = Balance × (APR / 12 / 100)
Principal Paid = Monthly Payment - Monthly Interest

As your balance decreases, less of each payment goes to interest and more goes to principal, gradually accelerating your payoff. The critical requirement is that your monthly payment must exceed the monthly interest charge — otherwise, the balance grows instead of shrinking.

Unlike fixed-term loans, credit card payoff time depends entirely on how much you pay each month. Minimum payments typically cover interest plus 1% of the balance, which is why they lead to very long payoff times. Doubling or tripling the minimum can cut your payoff time from decades to years.

Our calculator handles the final payment automatically — the last payment is adjusted to exactly zero out the remaining balance plus final interest, so you get an accurate total cost figure.

1. Pay more than the minimum. Minimum payments are designed to maximize interest revenue for the card issuer. Even $50 extra per month can save years of payments and hundreds in interest on a typical credit card balance.

2. Consider a 0% balance transfer.Transferring your balance to a card with 0% introductory APR for 12-21 months lets every dollar of your payment go toward the balance. Calculate whether the 3-5% transfer fee is less than the interest you'd otherwise pay.

3. Stop using the card while paying it off. Adding new charges while trying to pay down a balance is counterproductive. Switch to cash or a debit card for daily spending until the balance is cleared.

4. Use the debt avalanche method.If you have multiple cards, direct extra payments toward the card with the highest APR while making minimums on others. Once it's paid off, roll that payment amount into the next highest APR card.

5. Automate your payments. Set up automatic payments for more than the minimum to ensure consistent progress. Treat your credit card payment like a fixed bill, not a discretionary amount.
