1. What is Credit Card Interest?

Credit card interest is what banks charge you for borrowing money when you don't pay your balance in full each month. In Australia, credit card interest is typically calculated daily and charged monthly.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

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

Explanation: The equation calculates how much interest you'll pay each month based on your current balance and annual interest rate.
