Credit Card Payoff Calculator
The Credit Card Payoff Calculator shows you how long it will take to pay off your credit card balance and how much interest you will pay. It also calculates how much faster you can pay off the debt by increasing your monthly payment. Credit card interest is compounded daily, making it expensive to carry a balance. This calculator helps you create a realistic payoff plan by showing the impact of different payment amounts. Even a small increase in your monthly payment can save you hundreds or thousands of dollars in interest and cut years off your payoff time.
Formula
Months to Pay Off = −log(1 − (B × r) ÷ P) ÷ log(1 + r) B = current balance r = monthly interest rate (APR ÷ 12) P = monthly payment Total Interest = (P × Months) − B
Example
For a $5,000 balance at 18% APR with $200 monthly payment: Monthly rate = 18% ÷ 12 = 1.5% Months = −log(1 − ($5,000 × 0.015) ÷ $200) ÷ log(1.015) Months = −log(1 − 0.375) ÷ log(1.015) Months = −log(0.625) ÷ 0.00649 Months ≈ 30 months Total Interest = ($200 × 30) − $5,000 = $1,000
How to Use

- Enter your monthly payment amount
- See how many months it will take to pay off and total interest
- Try increasing your payment to see how much faster you can be debt-free
Frequently Asked Questions
How is credit card interest calculated?
Credit card interest is typically compounded daily. Your daily interest rate is your APR divided by 365. Each day, interest is calculated on your current balance and added to what you owe. This makes carrying a balance very expensive.
What is the minimum payment on a credit card?
Minimum payments are usually 1-3% of your balance or a flat fee (e.g., $25), whichever is higher. Paying only the minimum can take decades to pay off the balance and cost thousands in interest. Always pay more than the minimum if possible.
Should I use the avalanche or snowball method?
The avalanche method (paying off highest-interest debt first) saves the most money. The snowball method (paying off smallest balances first) provides psychological wins. Mathematically, avalanche is better, but snowball works if you need motivation to stay on track.
Will making biweekly payments help?
Yes. Making half your monthly payment every two weeks results in 26 half-payments per year, which equals 13 full monthly payments instead of 12. This extra payment goes directly to principal and can save significant interest.
Can I negotiate my credit card interest rate?
Yes. Call your credit card company and ask for a lower rate, especially if you have a good payment history. Mention competing offers. A reduction of even 1-2% can save hundreds of dollars per year.
