An outstanding $4,500 at 22% APR with $200 monthly payments takes years and adds interest.
Daily interest, new charges, fees and changing minimum payment schedules may change actual results.
A payment must be large enough to cover the month's interest and reduce the principal. The final payment is limited to the remaining balance.
Start with the example values, then replace them with amounts for the same transaction or time period. Double-check rates and units. The results are estimates intended to help you explore possible outcomes, not financial or tax advice.
When your payment only slightly exceeds monthly interest, most money goes toward interest rather than reducing the debt. That is why payoff time can be surprisingly long. Try a higher fixed payment to see the effect on the total interest.
This model assumes no new purchases and a constant APR. Card balances may accrue interest daily, promotional rates can expire and issuers can charge fees, so the statement schedule may differ.
A payment that does not cover the estimated first month of interest cannot reduce the principal under this simplified fixed-payment model, so the tool flags it.
After each month: balance = balance × (1 + APR ÷ 12) − payment
