1. What is the FNB Credit Card Interest Calculator?

This calculator helps FNB credit card holders estimate their monthly interest charges based on their current balance and the card's annual interest rate.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest (ZAR)
• \( P \) — Principal balance (ZAR)
• \( R \) — Monthly interest rate (annual rate / 12, as a decimal)

Explanation: The calculation converts the annual percentage rate to a monthly decimal rate, then multiplies by the principal balance to find the monthly interest charge.

3. Importance of Interest Calculation

Details: Understanding your monthly interest charges helps with budgeting and demonstrates the cost of carrying a credit card balance. It can motivate paying down balances faster.

4. Using the Calculator

Tips: Enter your current credit card balance in ZAR and the annual interest rate (found in your card agreement). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q3: How can I reduce my interest payments?

Q4: Does this calculation include fees?
