How to Use the Credit Card Pay Off Calculator

  1. Enter your current balance – the total amount you owe on the credit card (e.g., $2,500).
  2. Enter your APR – the annual interest rate as a percentage (e.g., 18.5 for 18.5%).
  3. Enter your monthly payment – the fixed amount you plan to pay each month (must be greater than the interest accrued).
  4. Optional: Add an extra payment – any additional amount you’ll pay monthly to speed up payoff (e.g., $50).
  5. Click Calculate to see results.

Results show:

  • Time to Pay Off – number of months (and years) to clear the balance.
  • Total Interest Paid – the total interest cost over the payoff period.
  • Total Amount Paid – sum of your balance plus all interest.

Note: All monetary values are in dollars ($). The monthly payment must exceed the monthly interest to reduce the debt; otherwise, the calculator will show an error.
