1. What is FNB Credit Card Interest?

The FNB Credit Card Interest is the monthly charge applied to outstanding balances on First National Bank credit cards in South Africa. It's calculated based on your principal balance and the annual percentage rate (APR).

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 (APR / 12, as a decimal)

Explanation: The annual percentage rate (APR) is divided by 12 to get the monthly rate, then multiplied by the principal balance to calculate the monthly interest charge.
