Credit Card Payoff Calculator
See exactly how long it will take to clear your credit card balance, how much interest you'll pay, and how much you save by paying more than the minimum.
Understanding the Credit Card Payoff Calculator
A credit card payoff calculator shows how long it will take to clear a balance and how much interest you will pay, comparing a fixed monthly payment against making only the minimum. Enter your balance, the card's APR, and your planned payment to see the payoff timeline, total interest, and the cost of paying just the minimum. It is for anyone trying to escape revolving debt faster. All calculations run privately in your browser.
How it works
Credit card interest compounds on the outstanding balance, usually daily, but a monthly model is close enough for planning. Each month the tool charges interest (balance x APR/12), adds it to the balance, subtracts your payment, and repeats until the balance reaches zero, counting the months. Minimum payments are typically a small percent of the balance (often 1-3%) plus interest, so they shrink as the balance falls, dragging payoff out for years. By comparing a fixed higher payment to the minimum, you can see how many months and how much interest you save by paying more.
Worked example
A 5,000 balance at 22% APR. Monthly rate = 0.22/12 = 0.01833. Paying a fixed 200/month: month 1 interest is 91.67, balance drops to 4,891.67; it takes about 31 months to clear, with roughly 1,150 in total interest. Paying only a 2%-plus-interest minimum (starting near 175 and falling) stretches payoff past 8 years and costs several times more interest. Adding even 50/month to the fixed payment removes months and hundreds in interest.
Tips & common mistakes
- Paying only the minimum can keep you in debt for years; always pay more if you can.
- A fixed payment clears debt far faster than a shrinking percentage-based minimum.
- Tackle the highest-APR card first (the avalanche method) to minimize total interest.
- Stop adding new charges while paying down, or the balance never falls.
- A 0% balance-transfer offer can help, but watch for transfer fees and the post-promo rate.

Frequently Asked Questions
How is the payoff time calculated?
We simulate your balance month by month: each month interest is added (APR ÷ 12), then your payment is subtracted. We repeat until the balance reaches zero, counting the months and total interest along the way.
Why does paying only the minimum cost so much more?
The minimum payment is usually a small percentage of the balance, so it shrinks as the balance drops — meaning most of your payment goes to interest and the balance barely moves. Paying a fixed, higher amount clears the principal far faster.
What if my payment never pays off the card?
If your monthly payment is less than the monthly interest, the balance grows forever. The calculator will warn you and ask for a higher payment.
