1. What is Simple Interest?

Simple interest is a method of calculating interest charged on a loan or earned on an investment. It's calculated only on the initial principal amount, without compounding over time.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Total interest (₹)
• \( P \) — Principal loan amount (₹)
• \( r \) — Annual interest rate (as a decimal)
• \( t \) — Time period in years

Explanation: The formula multiplies the principal amount by the interest rate and time period to calculate the total interest payable.

3. Importance of Interest Calculation

Details: Understanding interest calculations helps borrowers make informed decisions about loans, compare different loan offers, and plan their finances effectively.

4. Using the Calculator

Tips: Enter the principal loan amount in ₹, annual interest rate as a percentage, and time period in years. All values must be positive numbers.
