How Long to Pay Off $15,000 at 24% APR Paying $500 a Month

If you owe $15,000 on a credit card at 24% APR and pay $500 every month, the balance reaches zero in about 47 months (3 years and 11 months). You will pay roughly $8,137 in interest, for a total of $23,137.

That result assumes the rate stays fixed, no new charges are added, and every payment is made on time. Small changes to any of those assumptions move the date. Interest is about $300 in month one — exactly 60% of the payment. Over the life of this payoff, interest reaches roughly 54% of the original balance, which is the clearest argument for changing the rate before changing the payment.

What the payment covers in the first year

The first monthly interest charge is about $300. Your $500 payment therefore applies roughly $200 to principal in month one. That ratio improves slowly: by the end of the first year the balance is still close to its starting point, which is why early payoff progress can feel invisible.

Across the full payoff, interest equals about 54% of the original balance. That figure — not the monthly payment — is the real cost of the schedule.

What would shorten the payoff

Raising the payment to $650 shortens the payoff by about a year and saves more than $2,000. Splitting the balance across a 0% transfer and the existing card can reduce the blended rate without requiring a full transfer.

Is consolidation or refinancing worth it?

At $15,000, a fixed-rate consolidation loan becomes competitive. Compare a 13%–15% five-year loan against the $8,137 interest shown here, and confirm there is no prepayment penalty.

Compare the total interest figures, not the monthly payments. A longer loan almost always has a lower payment and a higher total cost.

What to watch

Large revolving balances also suppress your credit score through utilization. Paying before the statement closing date can improve the reported ratio while you work the plan.

Treat the schedule as a baseline. Re-run the numbers after any rate change, windfall, or change in income.

Frequently asked questions

How long does it take to pay off $15,000 at 24% APR paying $500 a month?

About 47 months, or 3 years and 11 months, assuming a fixed rate and no new charges. Total interest is approximately $8,137.

How much of my first payment is interest?

Roughly $300 of the first $500 payment is interest at 24% APR. The rest reduces principal.

What happens if I pay extra each month?

Extra payments go to principal, which removes future interest. Even a modest increase compounds: the earlier in the schedule the extra arrives, the larger the effect.

Does this include fees?

No. Late fees, annual fees, origination fees, and balance-transfer fees are excluded. Add any fee to the balance if you want to see its effect.
