Understanding your result

If your payment is less than the monthly interest, the balance never falls — the tool warns you.

Formula and method

Each month interest (APR ÷ 12) is added, then your payment is subtracted. The tool repeats until the balance reaches zero.

Assumptions and limitations

It assumes a fixed APR and payment with no new spending or fees. Real cards may change rates, add fees and recalculate minimum payments monthly.

Worked example

A 5,000 balance at 19.99% paying 200/month clears in about 32 months with roughly 1,300 interest.
