Options

Fixed payment: Use the amount you expect to pay each month. The last payment is capped at the remaining modeled balance.
Percentage and floor: The entered percentage applies to the statement balance after interest, with the floor as the lower payment amount. This is a stated rule, not a fetched card agreement.

Supported inputs and limits

Up to 1,200 modeled months. Whole-cent amounts up to 1 trillion; annual rate 0–100%. Monthly interest is annual rate / 12, charged before payment with half-up cent rounding. Percentage mode applies its percentage to the statement balance after interest, with the entered floor. No new purchases, fees or changing rates. Final payment is capped; an unfinished or non-reducing result is not a payoff date.

A minimum-payment rule can extend repayment

A percentage payment usually falls as the modeled balance falls, until the floor controls it. Compare the schedule with a fixed payment using the same rate and starting balance. This page assumes no new purchases or fees and identifies non-reducing or unfinished balances instead of inventing a payoff month.

Questions about Credit Card Payoff Calculator

What does the percentage apply to?

The stated rule applies it to the balance after that month’s modeled interest, then compares it with the entered payment floor.

Why is the final payment smaller?

The model caps a payment at the remaining balance rather than producing a negative balance.

Why might the schedule never finish?

Payments can fail to cover interest, or a small payment can leave a balance beyond the supported 1,200-month window.
