See what an extra payment really buys you. Enter your balance, APR, your minimum payment, and any extra you can add — and see how much sooner you're debt-free and how much interest you save.
Estimate only — assumes a fixed APR and no new charges on the card. Real cards compound daily and minimums shrink as the balance falls; treat this as a planning guide.
On a high-APR card, most of your minimum payment goes to interest — only the rest lowers the balance. Every extra dollar goes straight to principal, so it compounds in your favor: less balance means less interest next month, which means even more of the following payment reduces the balance.
With several cards, two proven orders help: avalanche (pay the highest APR first) saves the most money; snowball (pay the smallest balance first) gives quick wins that keep you going. Use this calculator on your highest-rate card first, then roll its payment onto the next.
It depends on the balance, APR, and payment. This calculator solves for the exact months at your current payment plus any extra, and shows how much sooner you're done — and how much interest you save — versus paying the minimum.
Because the minimum is mostly interest on a high-APR card, so the balance barely moves. Adding even a small fixed extra each month can cut years and thousands in interest off the payoff.
