How to use this calculator
- Enter the balance, the interest rate (APR) and your monthly payment.
- Read how long it takes and the approximate interest.
How it works
Each month interest is added, then your payment reduces the balance. The tool counts the months until it reaches zero.
Worked example
$5,000 at 18% APR, $200/month. About 32 months to clear, with roughly $1,300 of interest.
Common mistakes
- Setting a payment that barely beats the interest — it'll take years; pay more to make a dent.
- Forgetting new spending on the card adds to the balance.
Frequently asked questions
Why must the payment exceed the interest?
If your payment is smaller than the monthly interest, the balance grows instead of shrinking, so it can never be paid off.
