Paying $250 a month on an $8,000 credit card at 24% APR takes 52 months to pay off. You'll pay $4,899 in interest, for a total of $12,899.
The math
Inputs
| Balance | $8,000 |
|---|---|
| APR | 24% |
| Monthly payment | $250.00 |
| Comparison payment | $350.00 |
The formula in words
Each month, interest = balance × APR ÷ 12 (24% ÷ 12 = 2% a month). The payment covers that interest first and the rest lowers the balance. Repeat month by month until the balance reaches $0, adding up the interest along the way.
Step by step
| Month | Starting balance | Interest | Payment | To principal | Ending balance |
|---|---|---|---|---|---|
| 1 | $8,000.00 | $160.00 | $250.00 | $90.00 | $7,910.00 |
| 2 | $7,910.00 | $158.20 | $250.00 | $91.80 | $7,818.20 |
| 3 | $7,818.20 | $156.36 | $250.00 | $93.64 | $7,724.56 |
| Year | Paid | Interest | Balance at end |
|---|---|---|---|
| Year 1 | $3,000 | $1,793 | $6,793 |
| Year 2 | $3,000 | $1,469 | $5,262 |
| Year 3 | $3,000 | $1,058 | $3,321 |
| Year 4 | $3,000 | $538 | $858 |
| Year 5 (4 months) | $899 | $40 | $0 |
| Monthly payment | Time to pay off | Total interest | Total paid |
|---|---|---|---|
| $250 | 52 months | $4,899 | $12,899 |
| $350 | 31 months | $2,798 | $10,798 |
Result
- Time to pay off: 52 months (4 years and 4 months)
- Total interest: $4,899
- Total paid: $12,899
- Interest charged in month 1: $160.00
- Amount that lowers the balance in month 1: $90.00
- Final payment: $148.52
- Time to pay off at $350 a month: 31 months (2 years and 7 months)
- Total interest at $350 a month: $2,798
- Time saved: 21 months (1 year and 9 months)
- Interest saved: $2,101
Assumptions
- No new charges, fees or rate changes on the credit card, and the same $250 payment every month (the last payment is smaller).
- Interest is figured monthly as APR ÷ 12. Card issuers usually charge interest on the average daily balance, which can add slightly more than shown.
- These are estimates that show how the math works, not financial, tax or legal advice. Lenders, card issuers and the IRS can calculate slightly differently.

What 52 months really means for you
Fifty-two months is four years and four months. That's a long time to keep sending $250 out the door every month. Over that stretch, you'll hand over $12,899 in total — $8,000 to erase the balance and $4,899 in interest. In other words, you're paying more than half the original balance again just for the privilege of paying it off slowly.
The first month shows how brutal the math is. At 24% APR, interest is 2% a month. On $8,000, that's $160.00 in interest in month one. Your $250 payment covers that $160.00 first, leaving only $90.00 to actually lower the balance. So after one full payment, the balance has barely moved. That's why the payoff feels stuck at the start: most of your money is going to interest, not the debt itself.
As the balance drops, the interest charge shrinks a little each month, so more of your $250 goes to principal. But the progress is slow. The final payment is $148.52, which means you'll make 51 full payments of $250 and one smaller payment at the end. If that feels like a long road, you're not wrong — it is.
What drives the payoff time
Three things control how long this takes: the balance, the APR, and the monthly payment. You already know the balance is $8,000 and the APR is 24%. The payment is $250. The APR is the quiet problem here. At 24%, the card is charging you 2% of the balance every month just to carry the debt. That's $160.00 in month one alone.
Because interest is calculated on the balance each month, a high APR means a big chunk of every payment disappears before it touches the principal. That's why the first payment only reduces the balance by $90.00. If the APR were lower, more of your $250 would go to the balance and the payoff would be faster. But with the numbers you have, 52 months is the result.
The payment amount matters just as much. At $250, you're barely outrunning the interest. The balance does go down, but slowly. The good news is that the process is predictable: each month, interest is balance × APR ÷ 12, the payment covers that interest first, and whatever is left lowers the balance. Repeat until zero. That's exactly how the 52 months and $4,899 in interest were figured.
How to change the outcome
The most direct lever you have is the monthly payment. If you can pay $350 instead of $250, the payoff drops to 31 months — that's 2 years and 7 months. You'd save 21 months, or 1 year and 9 months, and you'd pay $2,798 in interest instead of $4,899. That's $2,101 less in interest. Same balance, same APR, just a bigger payment.
That difference is worth sitting with. A larger monthly payment cuts more than a year and a half off the timeline and saves you over two thousand dollars. If the larger payment isn't possible every month, even occasional extra payments help, though the numbers here assume a steady $250 or $350. The point is that the payment size is the biggest thing you control.
You could also look at the APR. If you can move the balance to a lower-rate option, less of each payment goes to interest and more goes to principal. But be careful: balance transfers and consolidation loans often come with fees or their own terms. Run the numbers for your situation, and confirm the details with your card issuer or lender before you commit.
Practical next steps
First, check your actual statement. The estimate here assumes no new charges, no fees, and no rate changes. If you keep using the card, the balance won't go down as planned. Stop adding new charges if you can, so every payment chips away at the $8,000.
Second, look at your budget and see whether $250 is truly your maximum. If you can find room to pay more, the payoff time and interest savings are dramatic. Even a modest increase helps, though the exact result depends on your numbers. Use a payoff calculator or ask your card issuer for a payoff estimate based on your real balance and rate.
Third, set up automatic payments so you never miss one. A missed payment can mean fees and a higher penalty APR, which would change the math entirely. The estimate here assumes the same $250 payment every month with no interruptions.
Finally, remember these are estimates. Card issuers usually charge interest on the average daily balance, which can add slightly more than shown. Your lender or card issuer can give you the exact figures. This isn't financial, tax, or legal advice — just a look at how the math works so you can make a plan.
Frequently asked questions
How much interest will I pay in total?
You'll pay $4,899 in interest over the 52 months, bringing your total paid to $12,899. That's based on an $8,000 balance at 24% APR with a steady $250 monthly payment. Your actual interest could be slightly higher if your card issuer uses the average daily balance method.
What if I pay $350 a month instead?
At $350 a month, you'd pay off the balance in 31 months — 2 years and 7 months. You'd save 21 months and $2,101 in interest, paying $2,798 in interest instead of $4,899. The higher payment makes a big difference because more goes to principal each month.
Why does so little of my first payment go to the balance?
At 24% APR, interest is 2% per month. On $8,000, that's $160.00 in interest for month one. Your $250 payment covers that $160.00 first, leaving only $90.00 to reduce the balance. As the balance falls, the interest charge shrinks and more of each payment goes to principal.
Does this estimate include new charges or fees?
No. The calculation assumes no new charges, no fees, and no rate changes on the card. It also assumes the same $250 payment every month, with a smaller final payment of $148.52. If you add new charges or your rate changes, the payoff time and total interest will be different.
Is 52 months a fixed number?
It's an estimate based on the assumptions given. Card issuers usually calculate interest on the average daily balance, which can add slightly more than the monthly APR ÷ 12 method used here. Your actual payoff time may vary. Confirm the exact numbers with your card issuer.
