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 principal balance and the monthly interest rate (APR divided by 12).

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest (currency)
