Use this calculator to see how long it will take to pay off your credit card and how much interest you'll pay, or find the monthly payment you need to become debt-free in a certain time.
Enter your balance, interest rate and fixed monthly payment.
Enter your balance, interest rate and how many months you want to be debt-free in.
This credit card payoff calculator helps you estimate how long it will take to pay off your credit card balance and how much interest you will pay along the way. It works for single balances or multiple cards by entering your monthly payment amount.
Every month, two main things happen:
The formula used is:
Interest for month = Balance × (APR ÷ 12) Principal paid = Monthly payment – Interest New balance = Old balance – Principal paid
If your monthly payment is less than the interest amount, debt increases over time — that is how credit card debt traps people.
Monthly interest rate = 21% ÷ 12 = 1.75%
Your estimated payoff time ≈ 31 months
Total interest paid ≈ $1,681
Total repayment ≈ $7,681
There are three proven strategies:
Pay extra toward the card with the highest APR.
Pay extra toward the smallest balance.
Move debt from high-interest card to 0% APR card.
Benefits:Be careful: Many issuers charge 3–5% transfer fee.
If you only pay minimum amounts, payoff time becomes extremely long.
Example:Monthly minimum ≈ $100 first month
Estimated payoff time: 12–13 years
Total interest: $4,000+ depending on rate changes
This is exactly how banks profit.
Use this formula to calculate safe payoff speed:
Monthly Payment = Balance ÷ (Desired payoff months)Example:
If you want to finish in 12 months:
$6,000 ÷ 12 = $500 per month-----
Consider refinancing when:
Should I close my credit card after payoff?
No, unless it has an annual fee. Closing reduces credit score length-of-history component.
Will making two smaller payments per month help?
Yes, because interest applies to a smaller average daily balance.
Does credit score affect APR?
Yes — borrowers with credit score above 740 usually get noticeably lower rates.
Is paying just above minimum useful?
Slightly — but meaningful results come from structured payoff amounts.
Use this calculator to plan a realistic payoff strategy and eliminate revolving credit card debt more efficiently.
