1. What is Monthly Interest Calculation?

The monthly interest calculation determines the interest earned each month on a high-yield savings account based on the principal amount and annual interest rate.

2. How Does the Calculator Work?

The calculator uses the monthly interest formula:

Where:

• \( P \) — Principal amount in USD
• \( r \) — Annual interest rate in decimal form

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

3. Importance of Monthly Interest Calculation

Details: Understanding monthly interest helps savers project earnings, compare savings account options, and make informed financial decisions about their investments.
