Credit Card Payoff Calculator

Why does my minimum payment keep shrinking as I pay off my card?

Most issuers set your minimum as a percentage of your current balance (commonly 1-3%) with a small dollar floor. As you chip away at the balance, that percentage shrinks in dollar terms too — so your required payment drops even though you still owe money. This is exactly what makes minimum-only payoff schedules stretch out for years or decades.

How can a minimum payment 'never pay off' a balance?

If your minimum payment percentage is low enough relative to your APR, the required minimum can be less than or equal to that month's interest charge. When that happens, all (or more than all) of your payment goes to interest, and none — or negative — goes to reducing principal. Your balance stays flat or even grows, forever, until you pay more than the minimum.

What's a realistic APR to expect on a credit card?

As of the mid-2020s, average credit card APRs in the US typically run 20-25% for standard cards, and often higher (25-30%+) for store cards or subprime cards. Your actual rate is on your monthly statement — use that exact number here rather than a guess, since even a few points of APR meaningfully changes the payoff math.

Is it better to pay off the highest-interest card first, or the smallest balance first?

Mathematically, paying extra toward your highest-APR balance first (the 'avalanche' method) minimizes total interest paid. Psychologically, some people do better paying off the smallest balance first (the 'snowball' method) for quick wins that build momentum. If you're juggling multiple cards, our Debt Payoff Calculator can model a single balance either way — run each card through separately to compare.

Should I use a balance transfer or personal loan instead of just paying more?

If you qualify, a 0% APR balance transfer card (usually for 12-21 months, often with a 3-5% transfer fee) or a lower-rate personal loan can cut your interest cost dramatically compared to a 20%+ card rate — but only if you also commit to a real payoff plan and stop adding new charges. Moving debt without changing the payment habit just delays the same problem.

Does paying only the minimum hurt my credit score?

Making the minimum payment on time does not directly hurt your score — payment history rewards on-time payments regardless of amount. However, a high balance relative to your credit limit (your 'credit utilization') does hurt your score, and minimum payments keep utilization high for a long time simply because the balance barely moves.

What counts as a 'good' fixed payment to test in this calculator?

Try any amount noticeably above your current minimum — even an extra $50-100/month often cuts years off the payoff time and saves hundreds or thousands in interest, because more of each payment goes to principal instead of interest. Compare a few amounts to see where the payoff time and interest savings start to level off for your budget.

Why does the payment amount in the chart change every month for the minimum-only line?

Because the minimum payment recalculates monthly (percentage of the shrinking balance), while the fixed-payment scenario pays the exact same dollar amount every month until the balance hits zero. That's the core mechanical difference this calculator is built to show.
