About the Credit Card Minimum Payment Calculator
This credit card minimum payment calculator shows the real cost of paying only the minimum due each month. Because the minimum is recalculated from a shrinking balance, the payment falls as you pay — which is exactly why minimum-only repayment can stretch for decades. Enter your balance, APR and your card’s minimum payment formula to see the payoff time, total interest and total paid.
Most US issuers use one of two formulas: interest plus 1% of the balance, or a flat percentage of the balance (often 2%–3%), each with a dollar floor such as $25 or $35. Your card agreement lists the exact rule. The US CARD Act also requires statements to show a “minimum payment warning” with a similar estimate.
To show the way out, the calculator compares the minimum-only path with paying a fixed amount every month, and reports how much time and interest the fixed payment saves. It assumes no new purchases and interest charged monthly at APR ÷ 12.
With the default inputs, the months to pay off (minimums only) is 19 yr 1 mo. Change any value above to recalculate instantly.
How to use the credit card minimum payment calculator
- 1Enter your current balance and APR from your statement.
- 2Choose your card’s minimum payment formula and percentage (check the card agreement).
- 3Enter the floor amount, usually $25–$40.
- 4Enter a fixed monthly payment you could afford instead.
- 5Compare the payoff time and interest for both approaches.
Formula and method
Each month the calculator adds interest I = B × APR ÷ 12 to the balance to get the statement balance, then works out the minimum due with your issuer’s formula: either interest plus p% of the statement balance, or p% of the statement balance alone. The payment is never less than the floor (or the whole balance if smaller).
Because the minimum shrinks with the balance, repayment slows down over time, and with a percent-only formula close to the monthly interest rate the balance may never reach zero. The simulation stops at 100 years. The fixed-payment comparison uses the same monthly interest but a constant payment.

Worked examples
$5,000 at 22.99%, interest + 1% minimum
The first minimum is about $146.75 ($95.79 interest plus 1% of the $5,095.79 statement balance). As the balance shrinks so does the payment, so it takes 229 months — over 19 years — and $8,340 of interest. Paying a flat $200 instead finishes in 35 months with $1,871 of interest.
$2,500 store card at 27.24%, 3% minimum with $35 floor
A 3% minimum on a 27.24% card starts at $76.70 and drifts down to the $35 floor. Minimum-only repayment takes 158 months and costs $4,825 of interest — almost twice the original balance. $150 a month clears it in 22 months for about $677.
$10,000 at 19.99%, interest + 1% minimum vs $400
Minimum payments starting at $268.25 take 291 months (over 24 years) and $15,394 in interest. A fixed $400 a month pays it off in 33 months and saves about $12,352.
Frequently asked questions
How is a credit card minimum payment calculated?+
Most issuers use either the interest and fees charged plus 1% of the balance, or a flat 2%–3% of the balance, with a floor of about $25–$40. If the balance is below the floor, the minimum is the full balance. Your card agreement lists the exact formula.
How long does it take to pay off a credit card with minimum payments?+
Often 15–25 years. For example, $5,000 at 22.99% with an interest-plus-1% minimum takes about 229 months and costs roughly $8,340 in interest — more than the original balance.
Does paying only the minimum hurt my credit score?+
Paying the minimum on time keeps your account in good standing, but a high balance keeps your credit utilization high, which can weigh on your score. Paying the balance down lowers utilization.
What is the minimum payment warning on my statement?+
Under the US Credit CARD Act of 2009, statements must show how long it would take to repay the balance making only minimum payments, the total cost, and the monthly payment needed to repay it in three years.
What should I do if I can only afford the minimum?+
Stop new charges, call your issuer to ask for a lower APR or a hardship program, and look at a 0% balance transfer or a nonprofit credit counseling debt management plan to cut the interest.
