1. What is Monthly Interest Calculation?

The monthly interest calculation determines how much interest you earn each month on your high-yield savings account based on your principal amount and annual interest rate.

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 interest rate by 12 to get the monthly rate, then multiplies by the principal amount to calculate monthly interest earnings.

3. Importance of Monthly Interest Calculation

Details: Understanding monthly interest helps savers project earnings, compare different savings accounts, and make informed financial decisions about where to keep their money.

4. Using the Calculator

Tips: Enter principal amount in dollars, annual interest rate as a decimal (e.g., 0.05 for 5%). All values must be valid (principal > 0, rate between 0-1).
