Credit Card Minimum Payments: Why the Finish Line Moves
A minimum is designed to keep the account current, not to minimize cost. Because many formulas fall with the balance, the payment can shrink faster than the debt disappears.

See how payment size changes payoff time and interest instead of relying on the minimum.

Watch the balance fall month by month
Interest arrives before the payment reduces principal. New purchases can slow or stop the descent even when payment stays fixed.

Payoff month and interest cost
Calculated resultNot available
Use the statement APR, current balance and a repeatable payment without new purchases.
How monthly card payoff is projected
Each month accrues interest on the opening modeled balance, adds any new charges, then subtracts the entered payment. The loop continues until payoff or 1,200 months, making the effect of a payment that barely exceeds interest visible.
Why issuer results can differ
Issuers commonly use daily balances, multiple APR categories and exact posting dates. This monthly model is a planning estimate; use the statement payoff warning for account-specific terms.
This calculator supports The Real Cost of Credit Cards. Credit Card Minimum Payments: Why the Finish Line Moves explains which details can change the inputs. The calculation methodology shows how we handle timing, rounding and exclusions.
Evidence standard for this calculation
Use the statement APR, current balance and a repeatable payment without new purchases. Inputs remain in the browser and outputs are rounded for display.

When does a fixed payment repay the modeled balance?
The modeled payoff month is when the fixed payment, after interest and any new charges, reduces the balance to zero.
How much interest is avoided by increasing that payment?
Run the higher payment and compare total interest; the difference is the modeled interest avoided, assuming no added purchases or fees.
