Calculator
Credit cardpayoff calculator
Compare minimum and custom payments to estimate how long your card balance could take to clear and how interest changes.
Compare a minimum-payment path with what happens when you pay a little more each month.
You’ll see how long the balance lasts, and how much interest the card keeps adding along the way.

Understanding credit card payoff estimates
Why minimum payments can take longer
A minimum payment usually covers interest and only part of the balance. As the balance falls, the payment and payoff timeline depend on the card issuer’s formula, APR, and any new spending or fees.
What a larger payment changes
Paying more each month reduces the balance sooner. That can shorten the estimated timeline and reduce the interest charged, but the result assumes the APR, payment, and balance stay unchanged.
- Payment amount: Test an amount you could realistically keep paying each month.
- APR: A higher APR increases the interest added between payments.
- New spending: Additional purchases can make the estimate less representative of your statement.
How to use the result
Compare scenarios, then check the estimate against your card statement and terms. If you are considering a repayment plan or balance transfer, include fees and the post-promotion APR in your wider comparison.
