How long will it take to pay off a credit card?
Short answer
It depends on three things: your balance, your card's APR, and how much you pay each month. A 5,000 dollar balance at 22 percent APR with a fixed 150 dollar monthly payment takes about 52 months, roughly 4.3 years, and costs about 2,800 dollars in interest. The lever you control is paying more than the minimum, and well above your first-month interest charge. These are estimates, not financial advice.
The three numbers that decide everything
Payoff time comes down to your current balance, the annual percentage rate (APR) on the card, and the fixed amount you pay each month. Enter those three and the calculator returns how many months remain and how much interest you will pay.
One assumption matters: this holds your APR and payment steady and assumes you stop adding charges. A fixed payment is different from a minimum payment, which shrinks as your balance falls and drags payoff out much longer. Promotional rates, fees, and changing minimums can shift the real number, so treat any result as a solid estimate.
Turning APR into a monthly rate
Interest is charged monthly, but APR is an annual figure, so you divide by 12 to get the monthly rate. A 22 percent APR becomes 0.22 / 12 = 0.018333 per month.
Each month that rate applies to whatever balance remains. Only the part of your payment left after covering that interest actually reduces what you owe.
Why it takes longer than balance divided by payment
Dividing balance by payment looks tempting: 5,000 dollars at 150 dollars a month is about 33 months. The real answer is longer because part of every payment goes to interest, not principal.
In month one of that example, interest is 0.018333 x 5,000, about 92 dollars. Out of a 150 dollar payment, only about 58 dollars reduces the balance. As the balance falls the monthly interest falls too, so more of each payment attacks principal, but the early drag is why payoff stretches from 33 months to about 52.
The payoff formula
To compute it directly:
Months to pay off = -log(1 - (r x Balance) / Payment) / log(1 + r)
This is standard loan amortization math, since a card paid at a fixed amount behaves like an amortizing loan.
- r = the monthly interest rate, which is APR divided by 12, written as a decimal
- Balance = the amount you currently owe
- Payment = the fixed amount you pay every month
- The result is the number of months; divide by 12 for years
Worked example: 5,000 dollars at 22 percent APR
Owe 5,000 dollars at 22 percent APR, paying a fixed 150 dollars a month.
The monthly rate is r = 0.22 / 12 = 0.018333. First-month interest is 0.018333 x 5,000, about 92 dollars. Since 150 dollars clears that and leaves about 58 dollars, the balance falls.
Plugging into the formula gives about 52 months, roughly 4.3 years. Over that time you pay about 2,800 dollars in interest on top of the original 5,000 dollars. That interest total is the real cost of taking years to clear the balance.
The rule that decides whether you ever finish
There is a hard threshold in the formula: your monthly payment must be greater than r x Balance, the first month's interest. If it is not, the payment fails to cover interest, the balance holds or grows, and it never reaches zero.
In the example, first-month interest is about 92 dollars, so 150 dollars works. Pay only 90 dollars and the balance creeps up every month. This is why minimum payments are dangerous: they are often set just barely above the interest, so almost nothing goes to principal.
The further your payment sits above that first-month interest figure, the faster you finish and the less interest you pay. Small increases above the minimum have an outsized effect because they hit principal directly.
Common mistakes
A few habits keep balances alive far longer than expected. These are estimates to plan around, not financial advice.
- Paying only the minimum. Minimums often sit just above the monthly interest, so the balance barely moves and payoff drags on for years.
- Adding new charges. New purchases raise the balance interest is calculated on and reset your progress. A payoff estimate only holds if you stop adding to the card.
- Ignoring the APR. Two people with the same balance and payment can have very different timelines purely because of their rate. A higher APR sends more of each payment to interest.
- Trusting balance divided by payment. It always understates the time and ignores interest cost entirely.
Frequently Asked Questions
Why does my card take years to pay off when balance divided by payment says under three years?+
That shortcut ignores interest. On the 5,000 dollar, 22 percent APR example, about 92 dollars of your first 150 dollar payment goes to interest, leaving only about 58 dollars to reduce the balance. Interest takes a slice every month, stretching 33 months of simple division out to about 52 real months.
What happens if my monthly payment is too low?+
If your payment is less than the first month's interest (r x Balance), it does not cover the interest charge, so the balance stays flat or grows and never reaches zero. In the worked example, first-month interest is about 92 dollars, so any fixed payment at or below that leaves you stuck. Your payment must exceed that number for the balance to fall.
How is the monthly interest rate calculated from APR?+
Divide the APR by 12 and use it as a decimal. A 22 percent APR becomes 0.22 / 12 = 0.018333 per month. That rate applies to your remaining balance each month, so only the part of your payment above the interest charge reduces what you owe.
Why are minimum payments so bad for payoff time?+
Minimum payments are frequently set just above the monthly interest, so only a tiny sliver goes to principal. That keeps the interest-bearing balance high for a long time, which is how a manageable balance can take years and a lot of interest to clear. Paying a fixed amount well above the minimum breaks the cycle.
Does adding new purchases really reset my progress?+
Effectively, yes. Interest is charged on the whole balance, so every new charge increases the amount your APR applies to and adds months to the payoff. A payoff estimate only holds if you stop putting new spending on the card while you clear it.
