1. What is This Calculator?

This calculator computes the monthly interest on a principal balance of $3.5 million based on the annual interest rate you provide.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Monthly interest (currency unit)
• \( 3,500,000 \) — Fixed principal amount ($3.5 million)
• \( R \) — Monthly interest rate (annual rate / 12, as a decimal)

Explanation: The calculation converts the annual rate to a monthly rate by dividing by 12, then multiplies by the principal amount.

3. Importance of Interest Calculation

Details: Calculating monthly interest helps in financial planning, investment analysis, and loan management for large principal amounts.

4. Using the Calculator

Tips: Enter the annual interest rate as a percentage (e.g., enter "5" for 5%). The rate must be a positive number.
