How to use this calculator
Estimate payoff time and interest assuming no new charges. Enter amounts in the units shown, select the applicable options, and click Calculate. Use Reset to restore the starting values.
Calculation formula
Monthly interest = opening balance × APR/12; apply the selected payment rule.
Assumptions and accuracy
Review timing, rates, fees and result notes when comparing scenarios. Future returns and rates are assumptions rather than guaranteed outcomes. Monetary display follows the currency’s precision; intermediate calculations retain additional digits.

Worked examples
Pay down a zero-APR credit card with fixed payments
Illustrative inputs are specified in the steps below; the example link loads the complete settings. Unmentioned settings use the linked defaults.
- At zero APR with no fees or new purchases, twelve payments of 100 repay 1,200; interest totals zero.
Total interest: 0 USD.
Try these inputsCommon questions
Why does paying only a percentage minimum take so long?
As the balance falls, the percentage payment can fall too, slowing principal reduction until a floor payment applies.
What if my payment does not cover interest?
The balance cannot be repaid under that fixed-payment assumption. Increase payment or review the entered APR.
Scope and assumptions
The model uses APR divided into monthly interest and assumes no new purchases or unentered fees. Actual statement daily balances and promotional terms can differ.
