Credit Card Payoff Calculator

Enter your credit card balance, interest rate, and minimum monthly payment to see exactly when you'll pay off your card — and how much interest you'll pay along the way. Add an extra monthly payment to see how much time and money you can save.

This calculator uses a fixed minimum payment model. Enter the dollar amount you pay each month, not a percentage of your balance.

How It Works

Enter your credit card details and the calculator simulates your payoff month by month — adding interest, then subtracting your payment — until the balance reaches zero. It compares your minimum-only payoff timeline against what happens when you add extra money each month.

Why Extra Payments Matter for Credit Cards

Compound Interest

Interest Builds on Interest

Credit card interest compounds monthly — you're charged interest on your remaining balance, including any interest from previous months. This makes minimum-only payments especially costly over time, as most of your payment goes toward interest rather than reducing what you owe.

Faster Payoff

Break the Cycle Sooner

Even small extra payments make a significant difference. Since every extra dollar reduces your principal immediately, less interest accrues the following month — creating a compounding savings effect that shortens your payoff timeline dramatically.

How to Use This Calculator

1. Enter your current credit card balance — the amount you still owe.

2. Enter your annual interest rate (APR). You can usually find this on your credit card statement or by logging into your account.

3. Enter your minimum monthly payment — the fixed dollar amount you pay each month (not a percentage of your balance).

4. Optionally, enter an extra amount you can pay each month above your minimum.

5. Click "Calculate Payoff" to see your results.

Assumptions and Limitations

This calculator uses a fixed minimum payment model — you enter a specific dollar amount, not a percentage of your balance. It assumes a fixed APR for the entire payoff period and does not account for variable interest rates, annual fees, late fees, or irregular payment schedules. The calculation is a simulation for informational purposes only and does not constitute financial advice.

Frequently Asked Questions

How does a credit card payoff calculator work?
The calculator simulates your credit card balance month by month — adding interest to the remaining balance, then subtracting your monthly payment — until the balance reaches zero. It shows how long payoff takes and how much total interest you pay.
Why should I pay more than the minimum on my credit card?
Credit card interest compounds monthly. Paying only the minimum means most of your payment goes toward interest, not principal. Paying extra reduces your balance faster, which means less interest accrues each month — saving you money and getting you debt-free sooner.
How much interest can I save by paying extra each month?
The amount depends on your balance, interest rate, and extra payment amount. The calculator shows you the exact savings by comparing minimum-only payoff versus payoff with your extra payment.
What information do I need to use this calculator?
You need your current credit card balance, annual interest rate (APR), and minimum monthly payment. Optionally, you can enter an extra monthly payment to see how it affects your timeline.
Does the calculator store my credit card information?
No. All calculations run entirely in your browser. No data is sent to a server, stored, or tracked. Your financial information stays on your device.
Does this calculator account for variable interest rates?
No. This calculator assumes a fixed APR for the entire payoff period. If your credit card has a variable rate, your actual payoff time and interest paid may differ. For the most accurate results, use your current APR as a starting estimate.
What happens if my minimum payment doesn't cover the monthly interest?
If your minimum payment is less than the monthly interest charge, your balance will grow instead of shrinking — this is called negative amortization. The calculator will warn you if this is the case and suggest increasing your payment.
