FAQ

Questions Credit Card Payoff Engine owners ask.

  • 01

    How does the engine calculate interest?

    The engine uses daily compounding logic, dividing your APR by 365 to determine the daily rate. This ensures a highly accurate simulation of how credit card interest actually accrues.

  • 02

    Can I see a month-by-month breakdown of my payments?

    Yes. When using calculate_repayment_projection, the capability returns a detailed amortization table showing interest charged, principal reduced, and the remaining balance for every month.

  • 03

    What is the 'snowball effect' mentioned in the capability?

    The snowball effect refers to adding an extra amount to your standard monthly payment. You can use compare_payment_strategies to see exactly how much interest and time you save by applying this method.
