How it works
This simulates the balance month by month, the same way a card issuer does: each month, interest is charged on the remaining balance at rate ÷ 12, then your fixed payment is applied — first covering that interest, with the rest reducing the principal. This continues until the balance hits zero, with the final payment capped at whatever's actually left.
Because the balance shrinks a little more each month, less of your payment goes to interest and more goes to principal over time — the chart below shows that shifting split. If your payment doesn't even cover the first month's interest, the balance would never shrink, so this calculator flags that instead of returning a nonsensical answer.
FAQ
Why does a small increase in monthly payment cut the payoff time so much?
Because interest is recalculated on a shrinking balance every month, a slightly higher payment compounds: it reduces principal faster, which reduces next month's interest charge, which leaves even more of the following payment for principal. Small increases early in a high-interest balance tend to have an outsized effect on total time and interest paid.
Does this include annual fees, minimum payment warnings, or promotional rates?
No — this assumes a single fixed rate and a fixed payment amount for the entire payoff period, with no fees. Real cards often have variable APRs, promotional 0% periods that expire, and issuer-mandated minimum payments; use this as a baseline estimate, not an exact statement.
