Notes
This is a simplified model and may differ from your issuer’s method. To avoid negative amortization, the calculator forces a minimum payment that covers interest plus a small principal when needed.
Quick guide
Start with your current balance, APR, and the minimum payment rule from your statement. Keep one baseline scenario, then change only one field at a time to compare payoff months and total interest.
- Use both minimum payment fields if your issuer applies a percentage and a floor amount.
- If the page shows a capped payoff, your current minimum rule does not clear the balance within the simulated window.
- Use the copy buttons to keep a reproducible baseline before testing alternatives.
FAQ
What should I enter first?
Enter balance, APR, and at least one minimum payment rule. The calculator needs either a percentage, a fixed amount, or both.
Why might the balance never reach zero?
If the minimum payment is too low relative to interest, payoff can take extremely long. The calculator flags this as a capped result instead of showing it as normal completion.
How close is this to a real card statement?
It is a planning model. Your issuer may use daily balances, fees, or issuer-specific rounding rules that are not included here.
