1. What Is Simple Interest?

Simple interest is a straightforward method of calculating the interest earned on a principal amount over a specific time period. It is commonly used for savings accounts, short-term loans, and investments where interest is not compounded.

2. How Does The Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( Principal \) — Initial amount deposited or invested ($)
• \( Rate \) — Annual interest rate (as a decimal)
• \( Time \) — Time period in years

Explanation: The formula calculates interest based only on the original principal amount, without considering any accumulated interest from previous periods.

3. Importance Of Interest Calculation

Details: Understanding how interest is calculated helps individuals make informed decisions about savings, investments, and financial planning. It allows for better comparison of different savings account options and helps set realistic financial goals.

4. Using The Calculator

Tips: Enter the principal amount in dollars, annual interest rate as a percentage (e.g., 2.5 for 2.5%), and time period in years. All values must be positive numbers.
