1. What is Monthly Interest Calculation?

Monthly interest calculation determines the amount of interest earned on savings accounts each month based on the principal amount and annual interest rate.

2. How Does the Calculator Work?

The calculator uses the interest formula:

Where:

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

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

Details: Understanding monthly interest helps savers estimate earnings, compare savings account options, and plan for financial goals.

4. Using the Calculator

Tips: Enter principal amount in dollars and annual interest rate as a percentage. Both values must be valid (principal > 0, rate ≥ 0).
