Methodology and limits
How this calculator estimates payoff
The engine divides the entered APR into a monthly rate and applies it to the opening card balance before each modeled payment.
Interest and payments are rounded to cents. The final payment is reduced when it would otherwise exceed the remaining amount due.
Limitations
- Card issuers commonly use average daily balance methods, so statement interest can differ.
- The estimate does not model issuer minimum-payment formulas or future account changes.
