Frequently asked questions
- Why does a small extra payment cut the time so much?
- Once the payment clears the monthly interest, the entire extra amount reduces principal, which lowers next month's interest too. The effect compounds, so a modest increase shortens payoff and cuts total interest sharply.
- What happens if my payment is too small?
- If the payment does not exceed the first month's interest, the balance grows instead of shrinking and never clears. The calculator returns a flag in that case.
- Does this account for new purchases?
- No. It assumes a fixed payment, a constant APR, and no new charges. Adding purchases extends payoff and increases total interest beyond the estimate.
