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.
