1. What is the Credit Card Interest Calculation?

The credit card interest calculation estimates the monthly interest charged on your outstanding balance based on the card's annual percentage rate (APR). This helps Australian consumers understand how much interest they'll pay if they don't clear their balance.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest (AUD)
• \( P \) — Principal balance (AUD)
• \( R \) — Monthly interest rate (APR / 12 as decimal)

Explanation: The equation converts the annual rate to a monthly rate by dividing by 12, then multiplies by the outstanding balance.

3. Importance of Interest Calculation

Details: Understanding monthly interest helps consumers make informed decisions about credit card use and debt management in Australia's financial landscape.

4. Using the Calculator

Tips: Enter your current credit card balance in AUD and the card's APR percentage. The calculator will show the estimated monthly interest if the balance remains unpaid.
