Credit Card Payoff Calculator
See how long it could take to pay off a credit card balance and how your monthly payment changes the interest you pay.
How this calculator works
Enter your card details
Add the balance you owe, your card’s APR, and the amount you plan to pay each month.
Interest is added each month
The calculator divides your APR by 12 and charges that monthly rate on the balance at the start of the month.
Your payment covers interest first
Each payment pays that month’s interest. Whatever is left reduces your balance.
Repeat until the balance is $0
The same payment is made every month. The last one is usually smaller, because it only needs to clear what is left.
Why paying more changes the result
Two numbers set your payoff time: your APR decides how much interest each month adds, and your payment decides how much is left to reduce the balance.
Interest is charged on what you still owe
Each month’s interest is a share of your remaining balance, so a larger balance creates more interest.
Each payment covers interest first
Before any of your payment lowers the balance, it pays the interest added that month.
The rest reduces the principal
Only the part of your payment above that month’s interest lowers what you owe.
A smaller balance creates less interest
Paying more lowers the balance faster, so each later month adds less interest and more of every payment goes to principal.
Example payoff calculation
A $5,000 balance at 24% APR, calculated the same way as the calculator above.
The first month
- Monthly rate
- 24% ÷ 12 = 2%
- Interest in month 1
- 2% × $5,000.00 = $100.00
- Payment
- $200.00
- Goes to the balance
- $200.00 − $100.00 = $100.00
- Balance after month 1
- $4,900.00
The whole payoff
Paying $200 a month
- Paid off in
- 3 years
- Total interest
- $2,000.57
Paying $300 a month
- Paid off in
- 1 year, 9 months
- Total interest
- $1,143.33
Paying $100 more each month would save $857.24 in interest and pay off the card 1 year, 3 months sooner.
Assumptions
- Interest is charged once a month at the APR divided by 12, on the balance at the start of the month.
- Card issuers usually charge interest daily, using a daily periodic rate on your average daily balance. Real interest can differ slightly, typically by about 1% of the interest at common APRs.
- You pay the same amount at the end of every month, starting next month. The last payment is whatever clears the balance.
- No new purchases, cash advances, fees, or late payments are added.
- The APR stays the same until the balance is paid off. Promotional and penalty rates are not modeled.
- Results are estimates for education, not financial advice.
How Calcora calculates
- Every calculator explains the formula behind its result in plain language.
- Calculators are designed to run in your browser, so your inputs are not sent to Calcora.
- Results help you understand your options. They are not financial advice.
