1. What is Credit Card Interest?

Credit card interest is the amount charged by credit card companies for carrying a balance. It's calculated based on your principal balance and annual percentage rate (APR), compounded monthly.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest due (currency)
• \( P \) — Principal balance (amount owed)
• \( R \) — Monthly interest rate (APR / 12, as decimal)

Explanation: The formula calculates the interest charged for one month based on your current balance and APR.
