Enter your card balance and APR, choose the amount you can pay each month, and this calculator shows how long the card takes to clear, the date you will be done, and how much interest you will pay along the way. Flip it to minimum-payment mode and you can see, side by side with your own numbers, why paying only the minimum is the slowest and most expensive way out of card debt. There is no sign-up — the results update as you type.
You pay the same amount every month until the card is clear — the fastest simple plan to follow.

How the estimate works:the tool steps through the card month by month. Each month it charges interest on the balance that is left (balance times APR divided by 12), then applies your payment; in fixed mode the last month pays only what is left. Minimum mode uses a typical minimum-payment formula — your issuer’s formula may differ, and many set a small minimum dollar floor like the $25 used here. Estimates assume a fixed APR, no new spending, no fees or penalty rates and payments made on time every month — your real figures will differ if any of those change.
How to use this calculator
- Type in the balance from your latest statement and the APR from your card agreement.
- Stay on Fixed monthly payment and enter an amount you could realistically pay every single month.
- Read the four headline numbers: months to pay off, payoff date, total interest and total paid.
- Switch to Minimum payment only and compare — the gap between the two is what your payment habit is worth.
- Try raising the fixed payment a little and watch how quickly the interest figure falls.
Why a fixed payment beats the minimum
A minimum payment is designed to keep an account current, not to clear it. It is usually worked out as the month’s interest plus a small percentage of the balance — a typical minimum-payment formula, and your issuer’s formula may differ, and many set a small minimum dollar floor like the $25 used here. As your balance falls, so does the minimum, so the debt lingers. A fixed payment does the opposite: it stays the same size while the interest part of it shrinks every month, which means more and more of each payment cuts the balance itself. That is why the same card can take a handful of years to clear on a fixed payment and well over a decade on minimums.
A worked example
Take a card with a $4,000 balance at 24% APR. Pay a fixed $150 a month and the card is clear in 39 months: you pay $5,773.39 in total, of which $1,773.39 is interest. Now pay only the minimum each month on the same card and the story changes completely — 212 months, close to eighteen years, and $6,887.00 of interest, which is more than the original balance itself. That contrast is the key insight of this page: the minimum keeps the card alive; a fixed payment, even a modest one, ends it. Run the same comparison with your own balance and APR above.
Getting the payment into your budget
A payoff plan only works if the payment survives contact with a normal month. Pick a figure you can pay in a tight month, not just a good one, and treat it like a bill with a due date. If the fixed payment feels out of reach, our budgeting guides walk through finding the money line by line, and if a lower APR is on the table, our article on balance transfer credit cards explains what to check before moving a balance — a transfer can cut the interest, but fees and the end of the introductory period matter.

Frequently Asked Questions
How long will it take to pay off my credit card?+
It depends on three things: your balance, your APR and how much you pay each month. Enter them above and the calculator steps through the card month by month — charging interest on what is left, then applying your payment — to give you the month count, the payoff date and the total interest. A fixed payment clears a card far sooner than minimum payments, because the minimum shrinks as your balance falls while a fixed payment stays the same size.
Why do minimum payments take so long?+
A typical minimum payment is roughly the month's interest plus a small slice of the balance — this calculator uses interest plus 1% of the balance, with a $25 floor, and your issuer's formula may differ. Because the minimum is recalculated on a smaller balance each month, the payment gets smaller over time and most of each early payment is swallowed by interest. On the worked example below, minimum payments take 212 months and cost $6,887.00 in interest, against 39 months and $1,773.39 for a fixed $150 payment.
What happens if my payment is smaller than the monthly interest?+
The balance never falls — it can even grow. The calculator checks for this: if your fixed payment is no bigger than the first month's interest on your balance, it shows a warning instead of a payoff date. To start making progress, the payment has to be higher than the interest the card adds each month, and the further above it you get, the faster the balance drops.
Is a fixed payment better than paying extra when I can?+
Both work, because both put more than the minimum against the balance. A fixed amount is easier to plan around and you can raise it when your income rises. Irregular extra payments help too — anything above the minimum reduces the balance that next month's interest is charged on. The important part is not the shape of the plan so much as paying meaningfully more than the minimum, every month, and not adding new spending to the card.
Should I pay off one card or spread payments across several?+
If you have several cards, you still need to meet every minimum to stay in good standing, then aim any spare money at one card at a time. The snowball method targets the smallest balance first for quick wins; the avalanche method targets the highest APR first and usually costs less interest overall. Our guide to debt snowball vs avalanche explains both, and the Debt Payoff Calculator on this site runs the comparison across all your debts at once.
