1. What is Monthly Credit Card Interest?

Monthly credit card interest is the amount charged by credit card companies on outstanding balances. It's calculated based on your annual percentage rate (APR) and current balance, compounded monthly.

2. How Does the Calculator Work?

The calculator uses the monthly interest formula:

Where:

• \( Balance \) — Current credit card balance ($)
• \( APR \) — Annual Percentage Rate (%)

Explanation: The formula converts the annual rate to a monthly rate by dividing by 12, then calculates the interest on the current balance.

4. Using the Calculator

Tips: Enter your current credit card balance and annual percentage rate (APR). Both values must be positive numbers.
