How to use this calculator
This credit card payoff calculator shows how long your balance will take to clear and how much interest you'll pay. It also shows what happens if you pay only the minimum, side by side.
Enter these numbers from your latest statement:
- Balance. Your current statement balance.
- APR. The purchase APR on your statement. The average for accounts charged interest is about 22.15%.
- Mode. Choose fixed payment to enter what you'll pay each month. Choose debt-free by to pick a target month, and the calculator finds the payment you need.
- New monthly charges. Spending you'll keep putting on the card. Leave it at $0 if you've stopped using it.
- How the minimum is set. The default is interest plus 1% of the balance, at least $25. That's a common formula, but check your cardholder agreement.
You'll see months to payoff, total interest, a balance chart, and a month-by-month table. The minimum-payment comparison shows what doing the minimum would cost.
How we calculate your payoff
Each month, the calculator adds interest, adds any new charges, and subtracts your payment. It repeats until the balance hits zero.
Monthly interest ≈ balance × (APR ÷ 12)
New balance = balance + interest + new charges − payment
Your issuer actually charges interest daily, but the monthly version lands very close. To find the payment for a target month, we use the standard loan formula:
Payment = B × r / (1 − (1 + r)^−n)
r = APR ÷ 12, n = months
Worked example: $6,500 at 22.15%
Say you owe $6,500 at 22.15% APR and pay $250 a month with no new charges.
- First month's interest: $6,500 × 0.2215 ÷ 12 = $119.98
- So only about $130 of your first $250 goes to the balance.
- Months to payoff: 36 (three years)
- Total interest: about $2,437
Now compare minimum payments, using interest plus 1% of the balance:
- First minimum: $119.98 + $65 = $184.98
- The minimum shrinks as the balance falls, so payoff slows down.
- Months to payoff: about 257 (over 21 years)
- Total interest: about $10,927
| Plan | Monthly payment | Months | Total interest |
|---|---|---|---|
| Minimum only | Starts at $184.98, then falls | ~257 | ~$10,927 |
| Fixed $250 | $250 | 36 | ~$2,437 |
| Debt-free in 24 months | $337.69 | 24 | ~$1,605 |
| Debt-free in 12 months | $608.83 | 12 | ~$806 |
The minimum payment trap
The minimum payment is designed to keep your account in good standing, not to get you out of debt. Because it's tied to your balance, it gets smaller as you pay. That stretches the debt out for decades.
In the example above, paying $65 more than the first minimum saves about $8,500. It also cuts more than 18 years off the payoff.
Your monthly statement includes a minimum payment warning. It shows how long payoff would take at the minimum and what you'd pay to finish in three years. Federal rules require it. It's worth reading.
A simple fix: pick a fixed dollar amount and pay it every month, even as the minimum drops. That one habit does most of the work.
How credit card interest works
Daily periodic rate and average daily balance
Most issuers charge interest daily. They divide your APR by 365 to get the daily periodic rate. At 22.15%, that's about 0.0607% per day.
They apply that rate to your average daily balance. That's the total of each day's balance in the cycle, divided by the number of days. Paying earlier in the cycle lowers your average balance, so you pay a little less interest.
Grace periods
Most cards give you a grace period on purchases. If you pay the full statement balance by the due date, you pay no interest on those purchases.
If you carry any balance, you usually lose the grace period. New purchases then start building interest right away. That's why the calculator asks about new monthly charges: they make payoff slower than you might expect.
Pay off credit card in 12 or 24 months
Setting a deadline turns a vague goal into a number. Use the debt-free by mode, pick 12 or 24 months, and see your required payment.
For larger balances, here's what it takes on $10,000 at 22.15% with no new charges:
| Goal | Monthly payment | Total interest |
|---|---|---|
| 12 months | $936.67 | ~$1,240 |
| 24 months | $519.52 | ~$2,469 |
| $500 a month | $500 | ~$2,595 (26 months) |
| $300 a month | $300 | ~$5,669 (53 months) |
If the required payment is out of reach, try a longer target. Or look at ways to lower the rate.
Balance transfers and other ways to cut the rate
A balance transfer moves your debt to a card with a low or 0% intro APR. Transfer fees are typically 3%–5% of the amount moved. On $6,500, that's $195 to $325.
A transfer can save a lot if you pay off the balance before the promo ends. Divide the balance plus the fee by the promo months to get your target payment. Watch for these:
- The regular APR after the promo applies to anything left over.
- New purchases on that card may not get the 0% rate.
- You usually need good credit to qualify.
Other options include a fixed-rate personal loan, or simply calling your issuer to ask for a lower APR. If you have several cards, our debt snowball vs avalanche calculator shows the best order to pay them.
Common mistakes to avoid
- Paying only the minimum. It's the most expensive way to pay off a card.
- Ignoring new charges. Spending $200 a month while paying $250 means only $50 extra goes to the debt.
- Closing paid-off cards right away. It may raise your credit utilization and lower your score. Consider keeping old no-fee cards open.
- Draining all savings to pay the card. Keep a small cushion so a surprise bill doesn't go right back on the card. Our savings goal calculator can help you build one.
Frequently asked questions
How long does it take to pay off $10,000 in credit card debt?
At 22.15% APR, paying $300 a month takes about 53 months, with about $5,669 in interest. Paying $500 a month cuts it to about 26 months and $2,595 in interest. Paying only the minimum could take about 25 years.
How much do I need to pay to clear my card in 12 or 24 months?
Use the "debt-free by" mode. For a $6,500 balance at 22.15%, you'd pay about $609 a month for 12 months or about $338 a month for 24 months, assuming no new charges.
How is the minimum payment calculated?
It varies by issuer and is listed in your cardholder agreement. A common formula is the month's interest plus 1% of the balance, with a floor such as $25. Our calculator uses that formula by default.
How is credit card interest calculated?
Most issuers divide the APR by 365 to get a daily periodic rate. They apply it to your average daily balance for the billing cycle. At 22.15%, the daily rate is about 0.0607%.
Is a balance transfer worth the fee?
Often, if you can pay off the balance before the 0% period ends. A 3%–5% fee on $6,500 is $195–$325, which may be far less than the interest you'd pay at 22%. Avoid new purchases on the transfer card unless they also get the promo rate.
Does paying more than the minimum really matter?
Yes, a lot. On $6,500 at 22.15%, paying $250 a month instead of the minimum saves about $8,500 in interest and roughly 18 years of payments.
What is a grace period?
It's the time between the end of your billing cycle and the due date. If you pay the full statement balance by the due date, most cards charge no interest on new purchases. Carry a balance, and you usually lose the grace period until you pay in full again.
