1. What is Credit Card Monthly Interest Calculation?

Credit card monthly interest calculation determines how much interest you'll pay on your outstanding balance. It's based on your average daily balance and annual percentage rate (APR), converted to a monthly rate.

2. How Does the Calculator Work?

The calculator uses the credit card interest formula:

Where:

• \( I \) — Monthly interest (currency units)
• \( ADB \) — Average Daily Balance (currency units)
• \( R \) — Annual Interest Rate (%)

Explanation: The formula converts the annual percentage rate to a monthly rate by dividing by 12, then applies it to your average daily balance to calculate the monthly interest charge.

3. Importance of Interest Calculation

Details: Understanding how credit card interest is calculated helps consumers make informed decisions about debt management, payment strategies, and choosing credit cards with favorable terms.

4. Using the Calculator

Tips: Enter your average daily balance in currency units and annual interest rate as a percentage. Both values must be positive numbers for accurate calculation.
