Credit Card Payoff Calculator
Find out how long a fixed monthly payment will take to clear a credit card balance, and the interest it costs.
Understanding the Credit Card Payoff Calculator
Credit cards charge interest on the revolving balance each month, so paying only the minimum can stretch payoff out for years while interest accumulates. This calculator simulates paying a fixed amount every month — larger than the minimum — and tracks how the balance shrinks until it reaches zero.
Each month, interest is charged on whatever balance remains, and the rest of your payment reduces principal. Because the balance shrinks over time, the interest portion shrinks too, so later payments make faster progress on principal than earlier ones did.
If your monthly payment doesn’t exceed the interest being charged, the balance will never go down — it can even grow. This calculator will flag that scenario so you know a higher payment is needed to make real progress.

Example 1 — $6,000 balance at 22% APR
Example 2 — Same balance, higher payment
Common questions
The calculator will tell you the balance can never be paid off at that payment level, because interest is outpacing principal reduction. Increasing the payment even slightly above the interest charge is required to make progress.
A higher payment attacks principal faster, which means less balance is left to accrue interest each month going forward — the savings compound the same way growth does, just in reverse.
Yes, and many cards have variable APRs tied to broader interest rate benchmarks, so your real rate could shift over time. Re-run the calculator if your card’s rate changes.
As a rough rule, a guaranteed ‘return’ from eliminating high-interest debt (avoiding a 20%+ APR) is hard for most investments to beat consistently — paying down high-rate cards first is often the stronger move before investing extra cash.
Paying only the minimum can take several years, sometimes even decades, on a large balance, since minimum payments are calculated as a small percentage of the balance plus interest. A larger fixed payment dramatically shortens the payoff timeline.
Yes, paying down a balance lowers your credit utilization ratio, one of the more heavily weighted factors in most credit scoring models, which can meaningfully improve your score, sometimes within a single billing cycle.
Paying the highest interest rate first, called the avalanche method, saves the most money in total interest. Paying the smallest balance first, called the snowball method, can build motivation through quicker wins, even if it costs slightly more overall.
A balance transfer to a 0% promotional card can save significant interest if you pay off most or all of the balance before the promotional period ends. Factor in the transfer fee, typically 3-5% of the balance, when deciding if it’s worth it.
