Tips to pay off faster

Avalanche method

Pay the highest APR card first to reduce total interest.

Balance transfer

A 0% intro APR can help if you pay before the intro period ends.

Negotiate your APR

Call your issuer and ask for a lower rate.

Stop new charges

Payoff becomes much harder if new charges continue every month.

Frequently asked questions
How does credit card interest work?

Credit card APR is commonly converted into a daily or monthly rate. This calculator estimates payoff using monthly compounding for a clear amortization schedule.

What happens if I only pay the minimum?

Minimum payments can keep you in debt for years because a large part of each payment goes to interest instead of principal.

How can I pay off my credit card faster?

Increase the monthly payment, avoid new charges, negotiate your APR, or consider a balance transfer if the fees make sense.

What is APR?

APR means annual percentage rate. It is the yearly cost of borrowing before certain compounding effects and fees.
