1. What is the Credit Card Interest Calculation?

The credit card interest calculation estimates the monthly interest charges based on your principal balance and annual percentage rate (APR). This is particularly useful for understanding low-rate credit card charges in the Philippines.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

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

Explanation: The equation converts the annual rate to a monthly rate by dividing by 12, then multiplies by the principal balance to get the monthly interest charge.

3. Importance of Interest Calculation

Details: Understanding your monthly interest charges helps in budgeting and making informed decisions about credit card payments and debt management.

4. Using the Calculator

Tips: Enter your current principal balance in PHP and the annual percentage rate (APR). The calculator will show your estimated monthly interest charge.
