Short answer: on a $5,000 credit card balance at 24% APR with no new purchases, paying $150 a month takes about 56 months and costs roughly $3,300 in interest. Paying $250 a month takes about 26 months and costs roughly $1,450. An extra $100 a month saves about $1,850 and gets you out of debt more than two and a half years sooner.

The assumptions
- Starting balance: $5,000.
- APR: 24%, which is 2% per month on the remaining balance.
- A fixed payment every month, and no new charges.
Your own rate is printed on your statement. Many cards charge less than 24%, and some charge more; plug in your number to see your version of the table.
The numbers side by side
| Monthly payment | Time to pay off | Total interest (approx.) | Total paid (approx.) |
|---|---|---|---|
| $150 | 56 months | $3,300 | $8,300 |
| $250 | 26 months | $1,450 | $6,450 |
The reason the gap is so large: in the first month at $150, about $100 of your payment goes to interest and only $50 reduces the balance. At $250, $150 reduces the balance. A lower balance means less interest next month, and the effect compounds in your favor.
Where does the extra $100 come from?
- Cancel or pause one subscription audit. Review recurring charges once; many households find $30 to $60 they do not use.
- Use a windfall. A tax refund or bonus applied once shortens the timeline more than it seems.
- Cut the interest rate instead. If you qualify, a 0% promotional balance transfer or a lower-rate personal loan can do the work of extra payments. We ran the math in balance transfer vs personal loan on $8,000.
If you have several cards
Pay the minimum on all of them and send every extra dollar to one card. Choosing which one first is the avalanche (highest rate) versus snowball (smallest balance) decision, which we modeled on a real example in avalanche vs snowball.
What about the minimum payment?
Minimums are usually a small percentage of the balance plus interest, so they shrink as you pay down and stretch the timeline far beyond the examples above. Your statement includes a required “minimum payment warning” box showing how long payoff takes if you only pay the minimum. Read it once: it is the most honest number on the page.
Holiday spending warning
If you are adding gifts to a card that already carries a balance, interest starts on new purchases immediately because you no longer have a grace period. Consider debit or cash for gifts this season; we compare protections in credit vs debit card for holiday shopping.
Our take
With card interest this high, the best “investment” most people can make is paying down the balance, because every dollar saves you 24 cents a year with no risk. Before investing beyond an employer match (see 401(k) match or debt first), put a firm monthly payment on the card and automate it.
Method: standard amortization with monthly compounding at APR/12. Actual results vary with your statement date, rate changes and fees. This is educational content, not financial advice.
