Credit Card Payoff calculator
Payments that barely cover interest create very long payoff periods; extra principal can materially reduce time and cost.
- Use current balance and APR.
- Keep payment above interest.
- Exclude new charges.
Optional readingLearn how this calculator works
How the credit card payoff calculator works
Estimate payoff time and interest for a credit-card balance using a fixed monthly payment.
Monthly interest = balance × APR ÷ 12; the rest of the payment reduces principal.
Read our calculation methodology and limitations.
Make the payoff plan resilient to real statements
Interest accrues daily or monthly depending on the issuer, so a forecast is a planning path rather than an exact payoff quote.
Pay above the minimum
Minimum payments are designed to keep the account current, not necessarily to eliminate the balance quickly. A fixed higher payment makes progress easier to see.
Stop adding purchases
New charges, cash advances, and fees change the schedule. Use a separate spending method while executing the payoff plan when practical.
Recheck each statement
Update the balance, APR, and payment after rate changes or fees. Use the issuer’s payoff information for the final payment.
Example
Compare paying $300 or $450 monthly toward a $10,000 balance at 22% APR.
What affects the result
- A fixed payment must exceed monthly interest.
- Variable APRs can change the result.
- New purchases and fees delay payoff.
Frequently asked questions
Why does the calculator say to increase payment?
The entered payment does not reduce the balance enough to repay it within the model limit.
Does this model minimum payments?
No. It uses the fixed monthly payment you enter; issuer minimum-payment formulas vary.
