Credit Card Payoff Calculator — How Long & What It Costs

See exactly how long it will take to pay off your credit card — and how much interest it will cost — based on a fixed monthly payment. Enter your balance, APR, and what you can pay each month to find your debt-free date, or discover whether a low payment will ever clear the balance at all.

Most loan calculators answer “given a term, what’s the payment?” A credit card flips that question. You don’t sign up for a fixed term — you carry a revolving balance and decide how much to pay each month. So the useful question becomes: given what I can pay, how long until I’m debt-free, and what will the interest cost? This calculator answers exactly that by stepping through your balance one month at a time.

How the month-by-month math works

Each month your card charges interest on the remaining balance — your APR divided by 12. Your payment covers that interest first, and whatever is left chips away at the principal. The smaller balance then accrues a little less interest next month, so your progress quietly accelerates. We repeat that cycle until the balance hits zero, count the months, and add up every dollar of interest along the way — all in full precision, rounding only when we show you the result.

A worked example

Take the calculator’s defaults: a $5,000 balance at 20% APR, paying a fixed $200 a month.

  • Time to pay off: 33 months — about 2 years and 9 months
  • Total interest: roughly $1,522
  • Total you’ll pay: about $6,522 ($5,000 principal + $1,522 interest)
  • Final payment: only about $122, because the last month just clears what’s left

Now raise the payment. To be debt-free in 12 months instead, you’d pay about $463 a month — more each month, but you’d hand the bank hundreds less in interest. That’s the lever this tool exists to show: on a revolving balance, the monthly payment is the single biggest factor in what the debt ultimately costs.

The minimum-payment trap

Credit card minimum payments are typically just 1%–3% of the balance, so they shrink as the balance shrinks — which is why minimum-only payoff can drag on for a decade or more. Worse, on a high-APR card a low fixed payment can fail to cover the interest at all. Picture $5,000 at 25% APR: the first month alone accrues about $104 in interest, so paying $100 makes the balance grow, not shrink. When your payment can’t beat the first month’s interest, the balance is mathematically never paid off. This calculator detects that and tells you the minimum you need to exceed to start making real progress, instead of pretending a payoff date exists.

How to pay it off faster

  • Pay a fixed dollar amount, not the minimum. A flat payment keeps attacking the principal even as the minimum would fall away.
  • Add even a little. Because interest compounds on the balance, an extra $50–$100 a month can cut months — and hundreds of dollars — off the total.
  • Target the highest APR first. With multiple cards, the “avalanche” method (extra money on the highest-rate card, minimums on the rest) saves the most interest; the “snowball” method (smallest balance first) trades some savings for faster wins.
  • Lower the rate. A balance-transfer offer or a lower-rate personal loan reduces the APR you enter here — try it both ways to see the difference.

Estimates are for planning only and assume a fixed payment, a constant APR, and no new charges or fees; real card terms and minimum-payment formulas vary. Your statement is authoritative — see our disclaimer.

Frequently asked questions

How long will it take to pay off my credit card?
It depends on three numbers: your balance, your APR, and how much you pay each month. This calculator applies your fixed payment month after month — each payment covers that month’s interest first, and the rest reduces the balance — until it reaches zero. For example, a $5,000 balance at 20% APR paid down at $200 per month is gone in about 33 months and costs roughly $1,522 in interest.
Why does paying only the minimum keep me in debt for so long?
Credit card minimum payments are usually just 1%–3% of the balance, so most of each payment goes to interest and the balance barely moves. On a high-APR card the minimum can be only slightly more than the monthly interest, stretching payoff over a decade or more and multiplying what you repay. Paying a fixed amount above the minimum — rather than a shrinking percentage — is what actually clears the debt.
Can a credit card balance ever become impossible to pay off?
Yes. If your monthly payment is less than or equal to the first month’s interest, the balance never goes down — it stays flat or grows, so the debt is mathematically never paid off. For instance, $5,000 at 25% APR accrues about $104 of interest in the first month, so paying $100 makes no progress at all. This calculator flags that situation and tells you the minimum you must exceed to start reducing the balance.
How much faster will a higher payment clear my balance?
Because interest is charged on the remaining balance, every extra dollar you pay goes straight to principal and compounds your progress. Raising the monthly payment shortens the payoff time and cuts total interest sharply — often paying an extra $50–$100 a month can save months and hundreds of dollars. Try different payment amounts above to see the effect, including the payment needed to be debt-free within a year.
Should I pay off the highest-APR card first?
If you carry several balances, the "avalanche" method — paying extra on the highest-APR card first while making minimums on the rest — saves the most interest overall. The "snowball" method targets the smallest balance first for quicker psychological wins. Either way, the math here applies per card: lower the APR you’re attacking or raise the payment, and the payoff time and interest both fall.
