1. What is Simple Interest?

Simple interest is a method of calculating the interest charge on a loan based on the original principal amount, the interest rate, and the time period of the loan. It's commonly used for short-term loans and car loans.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

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

Explanation: The formula calculates the interest by multiplying the principal amount by the annual interest rate (converted to decimal) and then by the loan term in years.

3. Importance of Interest Calculation

Details: Calculating interest helps borrowers understand the true cost of a loan, compare different loan offers, and plan their finances accordingly.

4. Using the Calculator

Tips: Enter the principal amount in dollars, annual interest rate as a percentage (e.g., 5 for 5%), and loan term in years. All values must be positive numbers.
