This credit card payoff calculator shows exactly how long it will take to pay off your balance at a fixed monthly payment — and how much interest you will hand the card issuer along the way. Or flip it around: set a deadline, and it computes the monthly payment needed to be debt-free by then.
Credit card APRs averaged over 21% in 2025, which makes card debt among the most expensive money most people ever borrow. Seeing the real month count and total interest is often the push needed to raise the payment.
How Credit Card Interest Is Calculated
Card issuers charge interest monthly on your remaining balance. The monthly rate is your APR divided by 12, so a 24.99% APR costs about 2.08% of the balance every month.
Each month the calculator: (1) adds interest = balance × APR ÷ 12, then (2) subtracts your payment. Whatever your payment covers beyond interest reduces the principal. On a $5,000 balance at 24.99% APR, the first month’s interest is about $104 — so a $125 payment shrinks the debt by only $21, while a $250 payment cuts it by $146.
For a target payoff date, it uses the standard amortization formula: payment = B × r ÷ (1 − (1 + r)^−n), where B is the balance, r the monthly rate, and n the number of months.
The Minimum-Payment Trap
Minimum payments are designed to keep you in debt. Most issuers set the minimum at interest plus 1% of the balance, or a flat 2%–3%. At a 24.99% APR, monthly interest alone is about 2.08% of the balance — so a 2% minimum payment does not even cover the interest, and paying only slightly more barely moves the principal.
Worked example — $5,000 balance at 24.99% APR:
- $125/month: 87 months (7¼ years) and about $5,855 in interest — more than the original debt.
- $250/month: 27 months and about $1,535 in interest.
- $500/month: 12 months and about $666 in interest.
Doubling the payment from $125 to $250 saves roughly $4,320 and five years.
Example: Debt-Free in 24 Months
Suppose you owe $5,000 at 24.99% APR and want it gone in two years. The required payment is $266.83 per month.
Over 24 payments you would pay about $1,404 in interest, for a total of roughly $6,404. If instead you could move that balance to a 0% intro-APR transfer card (typical fee 3%–5%, i.e. $150–$250) and pay $208/month, you would finish in the same 24 months and keep most of that $1,404.
Strategies that speed things up: pay more than the minimum every month, put windfalls straight onto the highest-APR card, and stop new purchases on the card while paying it down.
Frequently Asked Questions
How long will it take to pay off my credit card?
Divide is not enough — interest compounds monthly. At 24.99% APR, a $5,000 balance takes 27 months at $250/month but 87 months at $125/month. Enter your balance, APR, and payment above for the exact month count; as a rule of thumb, paying 5% of the balance monthly clears typical card debt in about two years.
How is credit card interest calculated?
Issuers apply a daily or monthly periodic rate to your balance: APR ÷ 12 per month (or APR ÷ 365 per day on the average daily balance). At 24.99% APR, a $5,000 balance accrues about $104 in interest each month. Interest is only avoided entirely if you pay the full statement balance by the due date.
What happens if I only make the minimum payment?
You stay in debt for years and pay interest that can exceed the original balance. Minimums are typically interest plus 1% of the balance, so almost nothing goes to principal. On $5,000 at 24.99% APR, paying $125/month takes over 7 years and about $5,855 in interest — versus 27 months and $1,535 at $250/month.
Is it better to pay off credit cards with the avalanche or snowball method?
The avalanche method (highest APR first) is mathematically cheapest — it minimizes total interest. The snowball method (smallest balance first) gives quicker wins and helps motivation. Studies show people stick with snowball more often, so choose avalanche if you are disciplined and snowball if you need momentum. Either beats paying minimums everywhere.
Does paying off a credit card improve your credit score?
Usually yes, and often quickly. Credit utilization — balances as a percentage of limits — is about 30% of a FICO score, and paying a card down lowers it. Keeping utilization under 30% (ideally under 10%) is one of the fastest score improvements available. Keep the paid-off card open to preserve your average account age and total limit.
