Estimate only. Assumes no new charges, a fixed APR, and monthly compounding. Card issuers calculate interest on your average daily balance, so actual figures will vary slightly.
How credit card payoff math works
Credit card interest compounds against you every month. Each billing cycle, the issuer charges roughly one-twelfth of your APR on the balance you carry, and only the portion of your payment above that interest actually reduces what you owe. The monthly interest is:
Interest = Balance × (APR ÷ 12)
This calculator simulates that cycle month by month: it adds the interest, subtracts your payment, and repeats until the balance hits zero. In deadline mode it solves the same equation in reverse using the standard amortization formula, giving you the fixed monthly payment that lands on zero in exactly the number of months you choose.
A worked example
Say you carry a $6,000 balance at 22% APR. Interest alone is $110 in the first month ($6,000 × 22% ÷ 12), so a $200 payment only knocks $90 off the principal at first. Keep paying $200 a month and the card takes 44 months — about three years and eight months — to pay off, with roughly $2,791 in total interest. Raise the payment to $300 and the payoff drops to 26 months with about $1,543 in interest, saving you roughly $1,248. And if you want the card gone in exactly 24 months, you would need to pay about $311 per month, for around $1,470 in total interest.
Ways to pay off a card faster
- Pay more than the minimum: minimums are often set near 1–2% of the balance plus interest, which stretches payoff over many years.
- Stop new charges: this calculator assumes the balance is frozen; every new purchase resets your progress.
- Ask for a lower APR: issuers sometimes reduce rates for customers in good standing — a single phone call can shave several points.
- Consider a balance transfer: a 0% introductory offer can pause interest for 12–21 months, though transfer fees of 3–5% apply.
- Make payments biweekly: paying half your amount every two weeks works out to one extra full payment per year.
Why the minimum payment trap matters
The most important number on this page is the first month's interest. If your payment is at or below it, the balance never shrinks — it grows. That is why the calculator shows a warning instead of a payoff date when the payment cannot cover the interest. Federal rules require card statements to disclose minimum-payment payoff timelines for the same reason: minimums are designed to keep the account open, not to get you out of debt.
What this calculator does not include
Real card interest is computed on your average daily balance, not a single month-end figure, so actual charges will differ slightly from this estimate. The calculator also assumes a fixed APR — most cards carry variable rates tied to the prime rate — and it does not model annual fees, late fees, or promotional rates that expire. Treat the results as a planning estimate, not a statement forecast.
Frequently asked questions
Why does my balance barely move when I pay the minimum?+
Most of a minimum payment goes to interest, not principal. On a $6,000 balance at 22% APR, the first $110 of any payment just covers that month’s interest. Only the amount above the interest reduces what you actually owe, which is why small payments stretch payoff over many years.
How is credit card interest calculated?+
Issuers divide your APR by 365 and apply that daily rate to your average daily balance each billing cycle. This calculator approximates that with monthly compounding, which is accurate within a few dollars for planning purposes. Carrying any balance past the due date usually means losing your grace period on new purchases too.
Should I pay off my credit card or save first?+
Most planners suggest keeping a small emergency fund, often $1,000 or one month of expenses, then attacking card debt aggressively. A card charging 22% APR costs far more than a savings account earns, so extra dollars usually do more good against the balance. This is general education, not personal financial advice.
Does a balance transfer make sense for me?+
A 0% introductory transfer can save serious interest if you can clear the balance before the promotional period ends. Watch the transfer fee of 3–5% and the rate the card jumps to afterward. Divide your balance by the number of promo months to see the payment required to finish in time.
Is my financial information stored anywhere?+
No. All calculations run entirely in your browser. The balance, rate, and payment figures you enter are never sent to a server, logged, or saved.
