1. What Is Monthly Interest Calculation?

Monthly interest calculation determines the amount of interest accrued on a balance over one month, based on an annual interest rate. This is commonly used for loans, savings accounts, and credit cards.

2. How Does The Calculator Work?

The calculator uses the formula:

Where:

• \( Balance \) — Principal amount or outstanding balance
• \( Rate \) — Annual interest rate (percentage)

Explanation: The annual rate is divided by 12 to get the monthly rate, which is then multiplied by the balance to calculate the monthly interest amount.

3. Importance Of Monthly Interest Calculation

Details: Calculating monthly interest helps individuals and businesses understand interest expenses on debts or earnings on investments, aiding in financial planning and budgeting.

4. Using The Calculator

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