1. What is Monthly Interest Calculation?

The monthly interest calculation determines how much interest you earn or owe each month based on your account balance and annual interest rate. This is commonly used for savings accounts, loans, and other financial products.

2. How Does the Calculator Work?

The calculator uses the monthly interest formula:

Where:

• \( Balance \) — Account balance in dollars
• \( Rate \) — Annual interest rate percentage
• 12 — Number of months in a year
• 100 — Conversion from percentage to decimal

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

3. Importance of Interest Calculation

Details: Understanding monthly interest helps with financial planning, comparing investment options, and managing debt. It shows how much your money can grow or how much a loan will cost.

4. Using the Calculator

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