How Long Does It Take to Pay Off a Credit Card (and How to Cut It in Half)
How long it takes to pay off a credit card depends on three numbers: your balance, your APR and what you pay each month. The first two you mostly can't change today. The third one you can, and it matters far more than most people expect. Paying only the minimum can stretch a modest balance across two decades, while a fixed payment a little above the minimum can finish it in a couple of years.
Try it with your own card below. The defaults are a $6,000 balance at 24% APR with a $180 monthly payment, and $100 extra each month.
With those defaults, $180 a month takes 4 years and 8 months and costs about $3,987 in interest. Adding $100 a month cuts that to 2 years and 5 months and $1,913 in interest. That's 27 months sooner and $2,073 saved.
The minimum-payment trap
Card issuers set the minimum payment so it shrinks as your balance shrinks. A common formula is a small percentage of the balance, often around 1%, plus that month's interest and fees, with a flat floor such as $25 or $35 once the balance gets small. Your issuer's exact formula is in your cardholder agreement.
That shrinking payment is the trap. Each month you pay down a bit of principal, so next month's minimum is a bit lower, so you pay down even less principal. The balance keeps falling, but more and more slowly, and the last few hundred dollars can take years.
Here's what that looks like for a $5,000 balance at 24% APR, assuming a minimum of 1% of the balance plus interest, with a $25 floor:
- The first minimum payment is $150: $50 of principal and $100 of interest.
- Paying only the minimum, it takes 234 months to reach zero. That's 19 and a half years.
- Total interest over that time: $8,887, which is more than the original balance.
Now keep paying the same $150 every month instead of letting the payment shrink. The card is paid off in 56 months with $3,322 in interest. Same starting payment, same card, but you're done more than 14 years sooner.
You don't have to take this on faith for your own card. Under the federal CARD Act, your monthly statement includes a minimum payment warning. It shows how long it would take to pay off your balance making only minimum payments, what that would cost in total, and the monthly payment needed to pay it off in about three years. It's worth reading once.
The payoff formula
If you pay a fixed amount every month and add no new charges, you can calculate the payoff time directly. Let B be your balance, P your fixed monthly payment, and r your monthly rate, which is the APR divided by 12 (so 24% APR gives r = 0.02). Then the number of months is:
n = −log(1 − r × B ÷ P) ÷ log(1 + r)
For the $5,000 card at 24% with $150 a month: r × B ÷ P = 0.02 × 5,000 ÷ 150 = 0.667. So n = −log(0.333) ÷ log(1.02) = 55.5, which rounds up to 56 months. That matches the month-by-month count above.
The formula also shows when you'll never pay the card off: if r × B is equal to or bigger than P, the payment doesn't even cover the interest, and the balance never shrinks. On a $5,000 balance at 24%, that line is $100 a month.
Real statements will differ slightly, because most issuers calculate interest on your average daily balance and months have different lengths. But the formula gets you within a month or so.
Payoff table by balance and APR
Here's how long a fixed payment takes, calculated month by month. The first set of columns assumes you pay 3% of the starting balance every month; the second assumes 5%.
| Balance | APR | 3% payment | Months | Interest | 5% payment | Months | Interest |
|---|---|---|---|---|---|---|---|
| $2,000 | 18% | $60 | 47 | $793 | $100 | 24 | $396 |
| $2,000 | 24% | $60 | 56 | $1,329 | $100 | 26 | $580 |
| $2,000 | 29% | $60 | 69 | $2,115 | $100 | 28 | $766 |
| $5,000 | 18% | $150 | 47 | $1,984 | $250 | 24 | $989 |
| $5,000 | 24% | $150 | 56 | $3,322 | $250 | 26 | $1,449 |
| $5,000 | 29% | $150 | 69 | $5,287 | $250 | 28 | $1,914 |
| $10,000 | 18% | $300 | 47 | $3,967 | $500 | 24 | $1,978 |
| $10,000 | 24% | $300 | 56 | $6,644 | $500 | 26 | $2,899 |
| $10,000 | 29% | $300 | 69 | $10,574 | $500 | 28 | $3,828 |
Two patterns jump out. First, when the payment is a fixed share of the balance, the payoff time depends only on the APR, not the size of the debt. Second, going from 3% to 5% of the balance cuts the time roughly in half at 18% and by more than half at higher rates, and it cuts interest by half or more. At 29% APR, the 3% payment takes 69 months and the 5% payment takes 28.
How to cut the payoff time in half
Take the $5,000 card at 24% paid at $150 a month: 56 months. Here's what different fixed payments do:
- $200 a month: 36 months, $2,001 in interest.
- $250 a month: 26 months, $1,449 in interest.
- $300 a month: 21 months, $1,143 in interest.
So an extra $100 a month more than halves the payoff time and saves about $1,870 in interest. A few ways to get there:
- Freeze your payment. Pick a fixed amount, at least your current minimum, and set it on autopay. Don't let it drift down as the balance drops. This alone is the biggest win.
- Add a fixed extra amount. Even $25 or $50 on top helps, because every extra dollar goes straight to principal.
- Use windfalls. Tax refunds, bonuses and gifts can go to the card as one-time extra payments.
- Stop adding new charges. New purchases quietly undo your progress. Use a debit card while you pay the balance down.
- Ask for a lower APR. Some issuers will lower your rate if you call and ask, especially with a good payment history. There's no guarantee, but it costs you nothing.
- Consider a balance transfer. A 0% promotional APR can speed things up a lot, but there's usually a transfer fee of a few percent, and you'll want to clear the balance before the promo ends.
If you have more than one card, send the extra money to the highest-APR card first. Our guide to the debt avalanche calculator explains why that's the cheapest order.
