Calculation steps
Work through one step at a time or reveal the complete calculation. The steps use your current inputs.
How to calculate
Accrue monthly interest on opening balance, add new charges and any active-statement fee, then cap the entered payment rule at the total due.
Due=opening×(1+annual rate/12)+new charges+active statement fee
Worked example
Opening 1000 at 12% nominal annual, no new charges/fees and fixed payment 100 gives first-month interest 10, payment 100 and closing balance 910.
Assumptions and input details
This is a user-defined monthly scenario, not any issuer’s daily-interest or minimum-payment rules. New charges earn no interest until the next month here. No grace period, late fee, penalty rate or national rules are inferred. Zero/insufficient payments can leave or increase debt. A payoff month is reported only with no recurring new charges. Projection limit 600 months. No live market data or national tax rules are inferred. Enter consistent amounts in one currency unless explicitly stated otherwise.

Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
