A credit card payoff calculator tells you exactly when you will be debt-free and how much interest you will pay, based on your card balance, APR, and monthly payment. Enter those three numbers and it shows your payoff date, the number of payments it will take, and the total interest cost over the life of the payoff.
This free online tool is for anyone carrying a balance and wondering whether their payments are making progress: cardholders deciding between the minimum payment and a higher fixed payment, and anyone who wants a concrete debt-free date to work toward. It takes your current balance, the card’s annual percentage rate, and the amount you plan to pay each month, then simulates the balance month by month until it reaches zero. The output shows the payoff timeline, the total interest you will pay, and how much you save by paying extra — a $50 bump in your monthly payment can cut months off the timeline and hundreds of dollars off the interest. Every calculation runs instantly in your browser with no sign-up and no data stored.
Worked example
Inputs: card balance $6,000, APR 24%, monthly payment $200.
- Monthly rate: r = 0.24 ÷ 12 = 0.02
- First month’s interest: 6,000 × 0.02 = $120, so $80 of the $200 payment reduces principal
- Payoff months: n = −log(1 − 0.02 × 6,000 / 200) / log(1.02) = −log(0.40) / log(1.02) ≈ 0.916291 / 0.0198026 ≈ 46.27, so 47 payments
Result: debt-free in 47 months, total paid $9,254.63, total interest $3,254.63.
Raise the payment to $250 and the picture changes: n = −log(1 − 0.02 × 6,000 / 250) / log(1.02) = −log(0.52) / log(1.02) ≈ 33.02, so 34 payments, total interest $2,255.61. The extra $50 a month saves 13 months and about $999 in interest.
How to use it
- Enter the Card balance — the current amount owed on the card.
- Enter the APR — the card's annual percentage rate as a percent.
- Enter the Monthly payment — the fixed amount you plan to pay each month.
- Read your result: the debt-free date, the number of months, total interest paid, and total paid overall.
The formula behind it
Frequently asked questions
How long will it take to pay off my credit card?
It depends on your balance, APR, and monthly payment — the three inputs this calculator uses. A $6,000 balance at 24% APR paid at $200 a month takes 47 months; at $250 a month it takes 34. As a rule of thumb, paying only the minimum (usually 1–2% of the balance) stretches a $6,000 balance at 24% APR over a decade or more and roughly doubles what you repay.
How is the credit card payoff time calculated?
The standard formula is n = −log(1 − r × B / P) / log(1 + r), where B is the balance, P is the monthly payment, and r is the monthly interest rate. Equivalently, a calculator can simulate the balance month by month: add that month's interest, subtract the payment, repeat until zero. Both approaches give the same payoff date.
Should I pay more than the minimum payment on my card?
Yes, whenever you can. Minimum payments are designed to keep the account current, not to clear the debt quickly — most of an early minimum payment is interest. Every dollar above the minimum goes straight to principal, which also shrinks every future interest charge. Fixed, higher payments reach zero faster and cost far less overall.
Why is my balance barely going down each month?
Because interest is charged on the full balance first. On a $6,000 balance at 24% APR, the first month's interest alone is $120 — so a $200 payment only cuts principal by $80. This is why high-APR balances feel stuck: until the balance falls meaningfully, interest eats most of each payment.
Does paying off a credit card improve my credit score?
Usually, yes. Paying a balance down lowers your credit utilization — the share of your credit limit in use — which is a major scoring factor. Accounts in good standing that are paid off stay on your credit report and continue to support your score; closing the card afterward can shorten your credit history, so consider keeping it open.
