1. What is Credit Card Monthly Interest?

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

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest ($)
• \( P \) — Principal balance ($)
