1. What is Monthly Interest Calculation?

Monthly interest calculation determines the interest amount earned or paid each month based on an annual interest rate. This is commonly used for loans, savings accounts, and investments where interest compounds monthly.

2. How Does the Calculator Work?

The calculator uses the monthly interest formula:

Where:

• \( I \) — Monthly interest (₹ or currency)
• \( P \) — Principal amount (₹ or currency)
• \( r \) — Annual interest rate (decimal)

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

3. Importance of Monthly Interest Calculation

Details: Understanding monthly interest helps in financial planning, comparing loan options, evaluating investment returns, and managing personal finances effectively.

4. Using the Calculator

Tips: Enter the principal amount in ₹ or your currency, and the annual interest rate as a percentage. Both values must be positive numbers.
