1. What is Simple Interest?

Simple interest is a method of calculating the interest charge on a loan based on the original principal amount. It does not compound, meaning interest is not added to the principal for subsequent calculations.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Interest amount (currency)
• \( P \) — Principal amount (currency)
• \( r \) — Annual interest rate (decimal)
• \( t \) — Time period (years)

Explanation: The formula calculates how much interest you'll pay over the life of a car loan based on the initial amount borrowed, the interest rate, and the loan term.

3. Importance of Interest Calculation

Details: Understanding interest calculations helps borrowers compare loan offers, budget for car payments, and make informed financial decisions about vehicle purchases.

4. Using the Calculator

Tips: Enter the loan amount in dollars, annual interest rate as a percentage (e.g., 5.5 for 5.5%), and the loan term in years. All values must be positive numbers.
