Credit Card Payoff Calculator guide
Enter your card balance, APR, and monthly payment to see how long payoff takes, how much interest you will pay, and your debt-free date. It also shows the payment needed to clear the card in 12, 24, 36, or 60 months.
How payoff is calculated
Each month, the calculator charges interest on the current balance at the APR divided by 12, adds it to the balance, then subtracts your payment. It repeats until the balance hits zero and counts the months and the total interest. The final payment is smaller, covering just what is left.
If your payment doesn't exceed the first month's interest, the balance never shrinks, and the calculator tells you so along with the exact interest charge you need to beat. The targets section runs the math in reverse, showing the fixed monthly payment that clears the balance in 12, 24, 36, or 60 months.
Worked example: $5,000 at 22 percent APR
Month one's interest is $5,000 × 0.22 ÷ 12 = $91.67. Pay $250 and $158.33 goes to principal. Keep paying $250 and the card is gone in 26 months, with about $1,286 of total interest.
Change only the payment and watch what happens. At $150 a month, payoff takes 52 months and costs about $2,798 in interest. At $400, it takes 15 months and costs about $732. Paying $150 more per month than the $250 plan saves over $550 and nearly a year. The relationship isn't linear: the lower your payment, the larger the share that interest eats.
The minimum payment trap
Card issuers typically set the minimum at interest plus 1 percent of the balance, or a small percentage of the balance, with a floor around $25 to $35. Because the minimum shrinks as the balance shrinks, payoff drags on. On the same $5,000 at 22 percent with a minimum of interest plus 1 percent, it takes about 230 months, more than 19 years, and costs roughly $8,100 in interest, more than the original debt.
The Credit CARD Act of 2009 requires statements to show how long minimum payments will take and what payment would clear the balance in three years. Look for that box on your next statement. The fix is simple: pick a fixed payment, set it up as autopay, and don't let it fall as the balance falls.
Why real interest runs slightly higher
Most US issuers calculate interest using the average daily balance method. They divide the APR by 365 (some use 360) to get a daily periodic rate, apply it to each day's balance, and sum the result over the billing cycle, which compounds daily. This calculator uses monthly compounding, which lands a little low, typically by a small percentage of the total interest. The payoff month usually matches.
New purchases change everything. The model assumes you stop using the card. If you keep charging, the payoff date moves out, and you may lose the grace period on new purchases, so they start accruing interest immediately until the balance is paid in full.
Faster ways out
Avalanche versus snowball: with several cards, the avalanche method pays minimums on all and throws every extra dollar at the highest APR first, which minimizes interest. The snowball method targets the smallest balance first for quicker wins. Avalanche is cheaper; snowball helps some people stay motivated. The debt snowball calculator compares both.
Balance transfers: a card with a 0 percent intro APR for 15 to 21 months can save hundreds or thousands, but most charge a 3 to 5 percent transfer fee and the rate jumps after the promo. It only works if the payment clears the balance before the promo ends; use the targets row to find that number. Calling your issuer to ask for a lower APR works more often than people expect, especially with a long on-time history.
Before you start
Keep a small emergency fund, even $500 to $1,000, so a car repair doesn't go back on the card. Capture any employer 401(k) match, which usually beats paying down debt early. After that, a 22 percent card is effectively a guaranteed 22 percent return for every dollar you pay off, which no investment reliably matches.

Frequently asked questions
How long will it take to pay off $5,000 on a credit card?
At 22% APR, paying $250 a month takes 26 months and about $1,286 in interest. Paying $150 a month takes 52 months and about $2,798. Paying $400 takes 15 months and about $732.
What happens if I only make the minimum payment?
It can take decades. If the minimum is interest plus 1% of the balance (with a $25 floor), a $5,000 balance at 22% takes about 230 months, over 19 years, and costs roughly $8,100 in interest.
How is credit card interest calculated?
Most US issuers use the average daily balance: the APR ÷ 365 is charged on each day's balance, then summed for the billing cycle. This calculator uses APR ÷ 12 per month, which is close but runs slightly low.
Should I pay off the highest interest card first?
Mathematically, yes. The avalanche method (highest APR first) minimizes total interest. The snowball method (smallest balance first) costs a bit more but gives quick wins that help some people stick with it.
Is a balance transfer worth it?
Often, if you can pay the balance off during the 0% intro period. Transfer fees are commonly 3% to 5%. A 3% fee on $5,000 is $150, far less than the roughly $1,286 of interest in the 22% example.
Why does my balance barely go down?
At 22% APR, a $5,000 balance accrues about $92 of interest a month. If you pay $100, only $8 reduces the balance. Every dollar above the interest charge goes straight to principal.
Is my data uploaded?
Everything runs in your browser. Nothing you enter is uploaded to a server or stored by us.
Does paying off a credit card raise my credit score?
Usually yes. Credit utilization, your balance divided by your limit, is a major scoring factor, and lower utilization generally helps. Keeping it under 30 percent is common advice; under 10 percent is better.
