1. What is the Monthly Interest Calculation?

The monthly interest calculation determines how much interest you'll earn each month on your savings account balance based on the annual interest rate. This helps savers understand their expected monthly earnings.

2. How Does the Calculator Work?

The calculator uses the monthly interest formula:

Where:

• \( P \) — Principal amount ($)
• \( R \) — Annual interest rate (decimal)
• \( I \) — Monthly interest ($)

Explanation: The formula divides the annual rate by 12 to get the monthly rate, then multiplies by the principal amount to calculate monthly interest earnings.

3. Importance of Interest Calculation

Details: Understanding monthly interest helps savers plan their finances, compare different savings accounts, and estimate growth of their savings over time.

4. Using the Calculator

Tips: Enter the principal amount in dollars and the annual interest rate as a decimal (e.g., 0.05 for 5%). Both values must be positive numbers.
