Assumptions. Interest is calculated monthly as balance × APR ÷ 12 and applied before each payment (monthly compounding). If you leave a minimum payment blank, it is estimated as the largest of: 2% of the balance, one month's interest + 1% of the balance, or $25 — actual minimums vary by lender. Simulations stop at 600 months. Displayed amounts are rounded to the nearest cent.

How the math works
Time is the headline number on this page: given one card's balance and APR, how many monthly payments clear it, and how much interest those payments include. The ordering preset is snowball, which for a single balance is identical to avalanche — with one debt there is nothing to re-order, so the strategy choice does not change the numbers. Two scenarios make the time dimension concrete: paying only the estimated minimum each month, and paying a fixed larger amount. The schedule table lists every month's interest, payment, and remaining balance, so the path from the first payment to the last is fully visible. The simulation assumes no new purchases: the balance only moves down.
Minimum-only payments stretch the timeline because the early payments are mostly interest. Take a $5,000 balance at 24.99% APR. The month-one estimated minimum is the largest of 2% of the balance ($100), one month's interest plus 1% of the balance ($104.13 + $50 = $154.13), and $25 — so $154.13. That month adds $104.13 of interest, meaning roughly two-thirds of the payment covers interest and only about $50 reduces the balance. The estimate is recomputed from the current balance every month, so the payment shrinks as the balance falls and the tail of the schedule stretches across many small payments.
Four assumptions apply to every run. One, monthly compounding: interest accrues once per month at balance × APR ÷ 12, before payments. Two, the minimum-payment estimate described above, recomputed monthly from the current balance. Three, the simulation stops at 600 months: if minimum-only payments never catch up with monthly interest, the run ends at month 600 and reports the balance as not paid off within the simulation limit, with no debt-free date. Four, all math runs in full double precision with no per-month rounding; displayed dollars are rounded half-up to the nearest cent, and totals are summed from unrounded values before rounding.
The credit card payoff calculator runs the same engine across several cards at once, and the minimum-payment calculator puts the minimums-only cost front and center as its headline result.
Worked example
One card: $1,000 balance at 12% APR, $25 minimum entered, $100 monthly budget, starting November 2026.
| Month | Interest | Payment | End balance |
|---|---|---|---|
| December 2026 | $10.00 | $100.00 | $910.00 |
| January 2027 | $9.10 | $100.00 | $819.10 |
| February 2027 | $8.19 | $100.00 | $727.29 |
| October 2027 (month 11) | $0.58 | $58.98 | $0.00 |
The first three rows reproduce the engine's exact month-by-month values: interest is balance × 0.12 ÷ 12, added before the $100 payment. The final payment in month 11 is capped at the remaining $58.98, so less than the budget is paid that month. The full run: 11 payments, debt-free October 2027, $58.98 total interest, $1,058.98 total paid.
Frequently asked questions
How long does it take to pay off a credit card with only minimum payments?
It depends on the balance, APR, and the minimum formula, but the timeline is long because early payments are mostly interest. On a $5,000 balance at 24.99% APR, the first estimated minimum of $154.13 includes $104.13 of interest, so only about $50 reduces the balance. The schedule table shows the full month-by-month path.
How much faster is a fixed monthly payment than the minimum?
The calculator shows both timelines from the same inputs. In the worked example, a $1,000 balance at 12% APR with a $25 minimum takes 11 months and $58.98 of total interest at $100 per month. Raising or lowering the budget input re-runs the simulation immediately so the two month counts can be compared.
Why does the estimated minimum change every month?
The estimate is recomputed from the current balance each month as the largest of 2% of the balance, one month's interest plus 1% of the balance, or $25. As the balance falls, the computed minimum falls with it, which is why the tail of a minimum-only schedule stretches out over many small payments.
Does the calculator assume I stop making new purchases?
Yes. The simulation only reduces the entered balance; it does not model new charges, cash advances, or fees added during the payoff period. If the card keeps being used, the real timeline differs from the calculated one. Entering the current statement balance gives the snapshot the math starts from.
What does not paid off within 600 months mean?
It means the simulated payments never cleared the balance within the 600-month simulation cap — typically because minimum payments do not cover monthly interest and the balance grows. The cap bounds every run; no extrapolation beyond month 600 is shown, and no debt-free date is reported for such a plan.
How is total interest computed?
Each month, every unpaid card accrues balance × APR ÷ 12, and those amounts accumulate in full double precision with no per-month rounding. The displayed total is the unrounded sum rounded half-up to the nearest cent. Displayed monthly rows are each rounded independently, so they can differ from the total by a cent.
