Credit Card Payoff Calculator
See exactly how many months it takes to clear your balance, the total interest you'll pay, and how much you save by paying a little more — instantly, no sign-up. The formula is shown so you can trust the number.
Quick answer
Paying $250 a month on a $6,000 balance at 24.99% clears it in 2 years 10 months and costs $2,403 in interest. Of your very first payment, $124.95 goes straight to interest — almost exactly half. Change the inputs above and this answer updates with your own numbers.
Your balance falling to zero
The steeper the curve, the faster you're free. Small payment increases bend it sharply.
The minimum-payment trap vs paying more
Same balance and APR. See how minimum-only compares to your plan and to paying a bit extra.

Where your payment actually goes
Interest on a credit card is charged on the balance you carry, so the first thing every payment does is settle the interest that accrued this month. Only what is left touches the debt.
On a $6,000 balance at 24.99%, one month of interest is $124.95. Pay $250 and barely half of it — $125.05 — reduces what you owe. That ratio is why card debt feels immovable: for the first stretch you are mostly renting the money, not repaying it.
It improves as you go. Because interest is charged on a shrinking balance, every month a slightly larger share of the same payment lands on principal, and the curve accelerates toward the end. The hard part is genuinely at the start.
The $50 that halves your interest
The size of the payment matters far more than most people expect, because it changes both how much you pay and how long you pay it. Same $6,000 balance at 24.99%:
| Monthly payment | Time to clear | Total interest |
|---|---|---|
| $150 | 7 years 3 months | $7,025 |
| $200 | 4 years 0 months | $3,512 |
| $250 | 2 years 10 months | $2,403 |
| $300 | 2 years 3 months | $1,841 |
| $400 | 1 year 7 months | $1,269 |
| $500 | 1 year 2 months | $976 |
Look at the first two rows. Finding an extra $50 a month takes the payoff from 7 years 3 months down to 4 years and cuts the interest from $7,025 to $3,512. Fifty dollars a month roughly halves the cost of the debt.
At $150 a month you would pay more in interest than you originally borrowed. At $500 you pay $976. The balance is identical in both rows; only the payment changed.
Why the minimum payment never ends
Card minimums are typically calculated as a small percentage of the balance, often with a floor. That design has a quiet consequence: as the balance falls, so does the minimum. You are always paying a percentage of a shrinking number, which stretches the finish line ahead of you almost as fast as you approach it.
The way out is to fix the payment. Decide on an amount and keep paying it as the balance falls, instead of letting the required minimum decide for you. That single change converts a percentage-of-balance treadmill into an ordinary loan with an end date — which is what the table above assumes. The full mechanics are in the credit card minimum payment trap.
What the rate does
Same $6,000 balance, same $250 a month, varying only the APR:
| APR | First month's interest | Time to clear | Total interest |
|---|---|---|---|
| 15% | $75.00 | 2y 5mo | $1,178 |
| 20% | $100.00 | 2y 7mo | $1,726 |
| 24.99% | $124.95 | 2y 10mo | $2,403 |
| 29.99% | $149.95 | 3y 2mo | $3,275 |
Between 15% and 29.99% the total interest nearly triples. This is why moving the rate is worth real effort: a balance transfer to a 0% promotional card, a lower-rate personal loan, or simply calling and asking for a reduction. Card issuers do sometimes lower a rate for a customer with a good payment history who asks — it costs one phone call to find out.
If you do use a balance transfer, note the transfer fee and the date the promotional rate expires. A 0% period only helps if the balance is gone, or nearly gone, before the ordinary rate resumes.
How the payoff time is calculated
- n — number of months to clear the balance
- B — current balance
- r — monthly rate, the APR divided by 12
- P — your fixed monthly payment
The formula also shows exactly when a debt never gets paid off: if P is less than or equal to B × r, the payment does not even cover the monthly interest, the logarithm is undefined, and the balance grows forever. On $6,000 at 24.99% that threshold is $124.95 a month.

Example: clearing $6,000
$6,000 on a card at 24.99%, paying a fixed $250 a month.
- Cleared in 2 years 10 months.
- Total interest: $2,403 — about 40% of the original balance.
- Total paid: $8,403.
- Of the very first payment, $124.95 is interest and $125.05 is principal.
Raise the payment to $300 and it finishes seven months sooner, for $562 less. Drop it to $150 and it takes seven years and three months, and costs $7,025 — more interest than the balance you started with.
Frequently asked questions
How long will it take to pay off my credit card?
It depends almost entirely on the payment, not the balance. On $6,000 at 24.99%, $150 a month takes 7 years 3 months, $250 takes 2 years 10 months and $500 takes 1 year 2 months. Enter your own balance, APR and fixed payment above for the exact figure.
Why does my balance barely move?
Because interest is settled first. On a $6,000 balance at 24.99%, one month's interest is $124.95, so a $250 payment only reduces the debt by $125.05. It gets better every month as the balance shrinks, but the early months genuinely are the slow ones.
What happens if I only pay the minimum?
Minimums are usually a small percentage of the balance, so as the balance falls the required payment falls too — and the payoff date keeps sliding away. Paying a fixed amount instead of the shrinking minimum is the single change that turns a card into a debt with an end date.
Is a balance transfer worth it?
It can be, because the rate is what drives the cost: the same $6,000 paid at $250 a month costs $1,178 at 15% and $3,275 at 29.99%. Check two things first — the transfer fee, typically a percentage of the amount moved, and the date the promotional rate ends. A 0% period only helps if the balance is cleared, or nearly cleared, before the standard rate resumes.
Should I pay off my card or save first?
Card interest at 20-30% is far higher than any reliable return on savings, so mathematically the card wins by a wide margin. The common exception is holding a small emergency buffer first, because without one, the next unexpected bill goes straight back onto the card and the cycle restarts.
Can a payment be too small to ever clear the debt?
Yes, and the maths is unambiguous. If your payment is less than the monthly interest, the balance grows no matter how long you pay. On $6,000 at 24.99% that threshold is $124.95 a month — anything at or below it never finishes.
