Credit Card Payoff Calculator
See how long it takes to clear a credit card balance at a fixed monthly payment, and the total interest.
Enter your balance, APR, and monthly payment to see the timeline.
How to use the credit card payoff calculator
Enter your current card balance, the annual rate (APR), and the fixed amount you plan to pay each month. The tool shows how many months it takes to clear the balance and the total interest you pay along the way.
Try a few payment amounts to see the effect. A higher monthly payment clears the balance faster and cuts the interest, often by a lot.
How the payoff timeline is worked out
A credit card has no fixed term. You choose the payment, and the balance decides the timeline. The calculator works month by month. It adds one month of interest to the balance, subtracts your payment, then repeats until the balance reaches zero.
The monthly rate is the APR divided by 12. Take a $5,000 balance at 18% APR with a $200 monthly payment. It clears in 32 months, and the total interest comes to about $1,314. The last payment is smaller because only the remaining balance is left to pay.
Why a credit card differs from a fixed loan
A fixed-rate loan has a set payment and a set term: you know from day one when it ends. A credit card balance is revolving. The payment is up to you, and a small payment can stretch the balance over years while interest piles up.
That is why this tool focuses on the payment you choose rather than a term. If you want to model a fixed loan with a set number of years, use the loan calculator instead.
When the balance never clears
If your monthly payment is too small, it may not even cover the interest that builds each month. When that happens, the balance never falls and the debt grows. The calculator flags this and asks for a higher payment rather than showing a misleading number.
This is an estimate for general information, not financial advice. It assumes a steady APR, a fixed payment, and no new charges or fees. Your card’s terms may differ, so check your statement for the exact figures.
Frequently asked questions
- How is credit card payoff time calculated?
- The tool simulates each month. It adds interest at the monthly rate (APR divided by 12), subtracts your payment, and repeats until the balance hits zero. The number of months is the payoff time.
- Why does a small payment take so much longer?
- Interest is charged on the remaining balance every month. A small payment leaves a larger balance, which keeps generating interest. More of your money goes to interest and less to the balance, so it takes far longer to clear.
- What if my payment does not cover the interest?
- Then the balance never falls and the debt grows. The calculator detects this case and asks you to enter a higher monthly payment, rather than show a payoff time that would never happen.
- How is this different from a loan calculator?
- A loan has a fixed payment and a fixed term. A credit card balance is revolving: you pick the payment and the balance sets the timeline. Use the loan calculator for a fixed-term loan and this tool for a revolving card balance.
- Is this financial advice?
- No. It is a math tool for general information. It assumes a steady APR, a fixed payment, and no new charges or fees. For decisions about debt, confirm your terms and consider speaking with a qualified financial adviser.
