1. What is Monthly Interest Calculation?

Monthly interest calculation determines the amount of interest earned or paid each month on a principal balance at a given annual interest rate. This is commonly used for savings accounts, loans, and investments.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( Balance \) — Principal amount in currency
• \( Rate \) — Annual interest rate in percentage
• \( 12 \) — Number of months in a year

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

3. Importance of Interest Calculation

Details: Accurate interest calculation is essential for financial planning, understanding loan costs, estimating investment returns, and making informed financial decisions.

4. Using the Calculator

Tips: Enter the principal balance in currency units and the annual interest rate as a percentage. Both values must be positive numbers.
