Credit Card Payoff Calculator

How to use this calculator

Enter your card balance and APR, then pick how you plan to pay: minimum payments only, a fixed monthly amount, or a target date you want the balance gone by. The results update as you type — debt-free date, total interest, and a chart of the balance over time. The dashed line is what minimum payments alone would do, so the gap between the two lines is your plan's head start.

The slider is the part worth playing with. It answers one question: what would an extra payment each month actually change? Drag it and watch the date move. You can share any scenario with the link button — the numbers you entered become part of the link, so only share it with people you're comfortable seeing them.

Where to find your balance and APR on a statement

Your current balanceis at the top of your statement or app home screen — use the full balance, not the minimum due or the statement balance if you've spent since. Your APRlives in a table near the end of the statement, usually labeled “Interest Charge Calculation” or “Annual Percentage Rate”. Use the purchase APR — cash advances and promotional balances have their own rates, but the purchase rate usually covers most of the balance.

If you can't face opening the statement today, that's okay — the defaults here ($4,000 at 24%) are close to the national averages, and the shape of the answer will already be honest. Swap in your real numbers when you're ready.

How credit card minimum payments are actually calculated

There is no single formula — each issuer picks one and states it in your card agreement. The most common is this month's interest plus 1% of the balance. Others charge a flat percentage of the balance, usually between 2% and 5%. Nearly all set a floor around $25, so the minimum never drops below that until the final payment.

That's why the calculator has a formula dropdown: it works as a credit card minimum payment calculator for whichever formula your issuer uses. The formulas differ more than they look — interest-plus-1% shrinks as you pay, which stretches the payoff far longer than a flat 4% would. And a flat 2% at a 24% APR doesn't amortize at all: the payment exactly covers the interest, and the balance never moves. The calculator will tell you, calmly, when that's the case.

Why the balance barely moves at minimum payments

On the default scenario — $4,000 at 24% APR — the first minimum payment is $120. Of that, $80 is interest. Only $40 touches the balance. Next month the minimum is a little smaller, and the split is nearly the same. Paying every month and watching the balance stand still isn't a discipline problem; it's the design of the minimum payment doing exactly what it was built to do.

We walk through this math slowly, with no shame attached, in Why Isn't My Credit Card Balance Going Down? The Math, Explained. The short version: the math is expensive, and you are not failing.

What an extra payment of $25, $50, or $100 a month does

At minimum payments, the default $4,000 balance takes 212 payments — over 17 years — and about $6,887 in interest. Adding $50 a month clears it in 56 months, with about $2,137 in interest — 13 years sooner, and roughly $4,750 saved. Here is the full picture:

Notice the shape: the first $25 does the most dramatic work, cutting more than ten years off the timeline. $25 a month changes the date — that is a first-class result, not a consolation prize. If you're juggling more than one card, our snowball vs. avalanche guide covers how to point that extra amount at the right card.

Glossary

APR

Annual percentage rate — the yearly cost of carrying a balance. Card interest compounds monthly, so each month charges roughly APR ÷ 12 on what you owe.

Minimum payment

The smallest amount that keeps your account in good standing — calculated by your issuer's formula, not by what pays the debt off efficiently.

Principal

The part of your payment that actually reduces the balance — whatever is left after that month's interest is covered.

Amortization

The month-by-month schedule of payments splitting into interest and principal until the balance reaches zero. The expandable table above is your card's amortization schedule for the scenario you set.
