1. What is Monthly Interest Calculation?

Monthly interest calculation determines how much interest a bank pays or charges on a principal amount each month. It's based on the annual interest rate divided by 12 months.

2. How Does the Calculator Work?

The calculator uses the monthly interest formula:

Where:

• \( I \) — Monthly interest (currency units)
• \( P \) — Principal amount (currency units)
• \( R \) — Annual interest rate (%)

Explanation: The formula converts the annual interest rate to a monthly rate by dividing by 12, then applies it to the principal amount.

3. Importance of Monthly Interest Calculation

Details: Understanding monthly interest helps consumers compare banking products, plan savings strategies, and calculate loan repayment amounts accurately.

4. Using the Calculator

Tips: Enter the principal amount in currency units and annual interest rate as a percentage. Both values must be positive numbers.
