Years to pay off a card balance at minimum payments only, plus total interest.

See how long it takes to pay off a credit card at minimum payments only and the total interest paid. Enter balance to see time to payoff and total interest.

5,000 balance at 22% APR with 2% minimum payments (so minimum declines as balance falls): several decades of minimum payments, with total interest dwarfing the original balance — more than the original balance in interest alone. This is why 'minimum payment only' is the worst debt payoff strategy — the card is designed to be maximally profitable at minimum payments.

The fix

Pay fixed monthly amount instead of percentage-based minimum. Even 50-100/month extra dramatically shortens payoff. Use the avalanche or snowball methods for multi-card balances.

Run it with sensible defaults

Using current balance of 5,000, apr of 22%, minimum payment of 2%, the calculation works out to 817 months. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Current Balance, APR, and Minimum Payment % — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

How the math works

Simulates monthly: balance accrues at monthly APR / 12, minimum payment = max(25, balance × min %). Ends when balance reaches zero. A 25 floor is typical to prevent infinite minimums on tiny balances. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Why payoff plans work

Debt feels overwhelming when it's an abstract total. Break it into a payoff date and a monthly figure and the problem becomes finite — you can see the finish line. That visibility is what this tool provides, and for many people it's the difference between dithering and acting.

What this doesn't capture

Real payoff journeys include missed payments, fee changes, balance transfers, and promotional rates that reset. The calculation assumes a steady plan; reality is rarely that clean. Use the figure as the best-case plan against which actual progress gets measured.

Frequently Asked Questions

Is 2% minimum realistic?
Cards typically 2-5% minimum or 25 floor, whichever is higher. often similar.
Why so many years?
Minimum payments decline as balance falls, so the final pound takes nearly as long as the first. High APR plus declining minimum creates a very slow payoff curve.
What about 0% promos?
Different dynamic — no interest accrues during promo. Minimum payments clear balance in promo period. The tool is for standard-rate balances.
How do I escape the trap?
Pay a fixed amount (100-300/month) instead of percentage. Or consolidate to a personal loan at lower rate. Or use balance transfer 0% cards to buy time for systematic payoff.
