Credit Card Minimum Calculator
Paying the minimum feels responsible: the payment is on time, the account stays current, and the balance barely moves. This credit card minimum payment calculator runs your balance month by month under your issuer’s actual minimum formula, so you can see the payoff time, the total interest, and the month the debt finally ends.
It also runs a second timeline. Enter any fixed monthly payment and the tool compares the two side by side, with an amortization table and a balance chart, because the gap between the two numbers is the real cost of the minimum-payment habit.
Educational estimate, not financial advice. Issuers vary; check your card agreement for the exact minimum formula. The simulation assumes no new purchases.

How this minimum payment simulation runs
Enter the balance and APR from your latest statement, then the percentage and floor from your card agreement, and pick the issuer method that matches your terms. Leave the fixed payment filled in if you want the comparison; clear it if you only want the minimum-only timeline.
Interest lands first. Each simulated month adds one month of interest: balance x APR / 12. At 22.99% on $3,000, that first charge is $57.48.
The minimum is recalculated. Method 1 takes the greater of the percentage of the updated balance or the floor. Method 2 takes the percentage of the updated balance and adds that month interest, with the floor underneath. The payment is capped at the full balance.
The payment comes off, and the loop repeats. Whatever is left becomes next month starting balance. Because a percentage minimum shrinks with the balance, the payment gets smaller every month, which is why the tail of the schedule stretches for years.
One display detail worth knowing: the headline first minimum payment, $60.00 in the example, is figured on the starting balance before month 1 interest lands. The first row of the amortization table, $61.15, is figured after that interest is added, because 2% of $3,057.48 is $61.15. The $1.15 gap is the two figures being taken at two points in the same month, not two different answers.
Two issuer formulas, two very different debts
Issuers do not share one minimum formula, and the choice changes the outcome more than most APR differences do.
| On $3,000 at 22.99% APR, 2% and $25 floor | Method 1: percent or floor | Method 2: percent plus interest |
|---|---|---|
| First table payment | $61.15 | $118.62 |
| Principal paid in month 1 | $3.67 | $61.15 |
| Time to pay off | 878 months | 111 months |
| Total interest | $30,218.11 | $2,466.18 |
| Total paid | $33,218.11 | $5,466.18 |
Method 2 amortizes faster for a simple reason: the interest is paid in full every month on top of a real principal slice, so the balance falls at the percentage rate from the start. Method 1 lets the percentage cover interest and principal together, so on a high-APR balance almost the whole early payment is interest. Month 1 under method 1 pays $57.48 of interest and $3.67 of principal. That split, repeated for years, is the whole story of the minimum trap. If you want the monthly rate behind these figures, the APR per month calculator converts any APR to its monthly equivalent.
Worked example: $3,000 at 22.99%, minimum against $150 fixed
The calculator is pre-filled with this case under method 1, and every figure below is what it returns.
| Measure | Minimum only | Fixed $150/month |
|---|---|---|
| First payment shown | $60.00 | $150.00 |
| Time to pay off | 878 months (73 years 2 months) | 26 months |
| Total interest | $30,218.11 | $819.34 |
| Total paid | $33,218.11 | $3,819.34 |
| Savings from the fixed payment | 852 months sooner and $29,398.77 less interest | |
The fixed payment does not need to be heroic to change the ending. The same simulation at other steady amounts gives 46 months and $1,505.89 in interest at $100 a month, 18 months and $570.85 at $200, and 14 months and $441.87 at $250. Each step up buys less extra time than the step before, because the first dollars above the minimum do the heaviest work: they are the dollars that stop the payment from shrinking. Once you have a target date in mind, the debt-free date calculator turns a payment plan into the calendar month you finish.
Why your statement already warns you about this
US statements carry a minimum payment warning by law. Regulation Z, the rule under the Truth in Lending Act, requires issuers to disclose how long minimum-only payments would take, what they would cost in total, and the payment that would clear the balance in 36 months, according to the Consumer Financial Protection Bureau text of Regulation Z section 1026.7. When the minimum cannot cover the interest at all, the statement must say the balance will never be repaid on minimums alone.
That warning is a snapshot of one statement balance. This calculator adds what the warning cannot: your choice of issuer formula, a fixed-payment comparison of your own amount, the month-by-month schedule behind the totals, and a chart of both balance curves. The Federal Trade Commission minimum payment explainer tells the same story at kitchen-table scale: a $300 purchase at 23% paid at the minimum takes over two years and $82 of interest.
Getting out faster than the minimum allows
The cheapest lever is a fixed payment you set yourself and treat as the new minimum. Pick an amount above the interest bar, $57.48 a month on the example balance, with enough margin that the principal falls every single month. Then keep it fixed when the issuer minimum drops. The drop is the trap door: every reduction in the required payment is an invitation to stretch the debt again.
Two other routes change the math itself. Paying extra directly against principal, priced out in the credit card extra payment calculator, shortens the schedule on the same card and APR. Moving or consolidating the debt, modeled in the credit card debt consolidation calculator, swaps the rate or the payment structure instead. Both only work if new spending stays off the card while the old balance falls.
What this calculator covers, and why each part matters
This calculator simulates paying off a credit card balance under the minimum payment, in the two ways issuers actually compute it, and compares that against a fixed payment you choose.
- Two issuer methods, selectable. The method is an input, not an assumption: percentage of balance, and percentage of balance plus monthly interest. The two are compared openly, because the same $3,000 balance at 22.99% APR with a 2% minimum and $25 floor takes 878 months (73 years 2 months) and costs $30,218.11 in interest under the percentage-of-balance method, but 111 months with $2,466.18 in interest under the percentage-plus-interest method.
- An amortization table, not just totals. The table shows the first 12 months payment by payment and then year by year, so the $3.67 of principal in month 1 is visible, not implied.
- An honest never. When a payment cannot cover the monthly interest, this calculator stops, warns you in plain language, and tells you the payment must rise above the interest. Federal disclosure rules treat that case as real; a calculator should too.
- A fixed comparison you set. Enter the fixed payment you could actually make, $100, $150, your number, and the savings line is computed from your figure: a fixed $150 a month on the same $3,000 balance ends the debt in 26 months with $819.34 in interest.
Frequently Asked Questions
Most issuers use one of two formulas. The first is the greater of a percentage of the balance, commonly 1 to 3 percent, or a fixed floor such as $25. The second adds that month's interest on top of the percentage. Your card agreement states which formula and floor your issuer uses, and this calculator offers both.
Far longer than most people expect. A $3,000 balance at 22.99 percent APR with a 2 percent minimum and a $25 floor takes 878 months, which is 73 years and 2 months, under the percentage-of-balance method. The same balance under the percentage-plus-interest method takes 111 months.
Yes. If the minimum is smaller than one month of interest, the balance grows even though you pay on time every month. This calculator says so directly and shows a warning instead of inventing a payoff date, which matches the never-pay-off disclosure federal rules require on statements in that situation.
It depends on your balance, APR, and minimum formula, and the differences are large. On the $3,000 example at 22.99 percent APR, the percentage method costs $30,218.11 in interest, more than ten times the original balance, while the percentage-plus-interest method costs $2,466.18.
Much faster, because a fixed payment does not shrink as the balance falls. Paying $150 a month on the $3,000 example clears the debt in 26 months with $819.34 in interest, saving 852 months and $29,398.77 compared with minimum payments under the percentage method.
Federal rules require your statement to show how long minimum-only payments would take, the total cost, and the monthly payment that would clear the balance in 36 months. This calculator goes further: it shows both issuer formulas, the full schedule, and any fixed payment you want to test.
Yes. The simulation adds no new purchases, no fees, and no APR changes. New charges would extend the payoff and raise the interest, so treat the result as the best case for the minimum-only habit, not a guarantee.
Any payment comfortably above one month of interest, which is your balance times APR divided by 12. On $3,000 at 22.99 percent that interest is $57.48 a month, so a payment must clear that bar by a real margin before the balance starts falling at a useful speed. Paying the statement balance in full avoids interest entirely.
The first 12 months in full detail: payment, interest, principal, and remaining balance for each month, followed by one row per year until the debt ends. It is the same simulation the headline totals summarize, so you can watch the payment shrink and the principal share grow month by month.
