Credit Card Payoff Calculator
Find out how long it takes to clear a credit card balance and how much interest you'll pay at a fixed monthly payment.
Example
With a $5,000 balance at 18% APR, paying $150/month: the first month's interest is $5,000 × (18% ÷ 12) = $75. Since $150 comfortably exceeds $75, the balance falls each month. It takes 47 months (about 3 yrs 11 mos) to clear, with roughly $1,983.60 in total interest and $6,983.60 paid overall.
How it works
Enter your current balance, the card's APR, and the fixed amount you pay each month. The tool simulates the payoff month by month and warns you if the payment is too small to cover the monthly interest.
Good to know
The Credit Card Payoff Calculator answers a single, concrete question: if you keep paying the same fixed dollar amount every month, how long until the card hits zero, and what will the interest cost you along the way? You plug in your current balance, the card's APR, and the flat monthly payment you intend to make, and it simulates the balance month by month until it clears. It's built for anyone carrying a revolving balance who wants a target payment rather than drifting along with the shrinking minimum the issuer prints on the statement.
Reach for it when you're deciding how aggressive to be: comparing what $150 versus $250 a month does to a $5,000 balance, sanity-checking whether a payment plan actually makes a dent, or setting a fixed autopay amount and wanting to know the finish date before you commit. Because it holds the payment constant, the results show the faster, more realistic outcome of disciplined fixed payments rather than the slow grind of percentage-based minimums.
Read the output as a set of linked numbers. The headline is the payoff time in years and months; "Total interest" is the extra you hand the lender on top of what you borrowed; "Total paid" is balance plus interest combined; and "First-month interest" is the line that decides whether you make progress at all. The two bars split your total spend into principal versus interest, so a fat interest bar is a visual cue that your payment is barely outrunning the finance charge.
One key caveat: if your payment is at or below that first-month interest figure, the calculator returns "Never," because every dollar is swallowed by interest and the balance grows. The fix is to push the payment above that number, and the further above it you go, the steeper the drop in both months and total interest. Remember the model assumes a constant APR and zero new purchases or fees, so any swipe you add to the card or a promo rate that expires will move the real finish line.
Frequently asked questions
Why does it say my card will never be paid off?
If your fixed monthly payment is less than or equal to the first month's interest (balance x APR/12), every payment is fully eaten by interest and the balance never shrinks - it actually grows. Raise your payment above that interest amount to make progress.
Why is the real payoff time longer than this estimate?
This tool assumes a constant fixed payment and no new charges. Real credit cards set the minimum payment as a percentage of the balance, so it drops as you pay down - stretching the payoff out for years. Paying a fixed amount, like this calculator assumes, is far faster.

People also ask
How is credit card interest calculated each month?
Most cards compute a monthly periodic rate by dividing the APR by 12, then apply it to the balance. For example, an 18% APR works out to roughly 1.5% per month, so a $5,000 balance accrues about $75 in interest in the first month. In practice many issuers use average daily balance and daily compounding, which can run slightly higher than a simple monthly estimate.
Does paying more than the minimum on a credit card save money?
Yes, paying a higher fixed amount sends more of each payment toward principal instead of interest, which shortens the payoff period and lowers total interest. Because issuer minimums shrink as the balance falls, sticking to them stretches repayment over many years, while a steady fixed payment clears the debt much faster.
What does APR mean on a credit card?
APR stands for Annual Percentage Rate, the yearly cost of borrowing on the card expressed as a percentage. Card APRs are typically variable and tied to a benchmark rate, and a single card can carry different APRs for purchases, balance transfers, and cash advances.
Is it better to pay off one credit card or pay a little on several?
Two common approaches are the avalanche method, which targets the highest-APR balance first to minimize total interest, and the snowball method, which clears the smallest balance first for psychological momentum. Both require making at least the minimum on every card to avoid penalties; the avalanche generally costs less interest overall.
Will using a credit card payoff calculator affect my credit score?
No. This calculator runs entirely in your browser and only performs math on the numbers you type, so it does not access your credit file or trigger any inquiry. It has no connection to credit bureaus or your actual accounts.
How accurate is a fixed-payment payoff estimate compared to my real statement?
It is a close estimate for the scenario of paying a constant amount with no new charges, but real results can differ because issuers may compound daily, change a variable APR, or add fees. New purchases on the card also reset progress, so the actual payoff date can be later than the estimate.
Why does my credit card balance barely go down each month?
When your payment is only slightly larger than the monthly interest, most of it covers the finance charge and very little reduces the principal. Lowering the balance faster usually means increasing the payment so a larger share lands on principal, and pausing new charges on the card.
