1. What is Car Loan Interest?

Car loan interest is the cost you pay to borrow money for a vehicle purchase. It's calculated based on the principal amount, interest rate, and loan term. Understanding this helps you compare loan offers and budget effectively.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( Principal \) — Original loan amount ($)
• \( Rate \) — Annual interest rate (as decimal)
• \( Time \) — Loan term in years

Explanation: This formula calculates the total interest you'll pay over the life of the loan. For monthly payments, divide the result by the number of months in the loan term.

3. Importance of Interest Calculation

Details: Knowing the total interest helps you understand the true cost of the loan, compare financing options, and make informed decisions about down payments and loan terms.

4. Using the Calculator

Tips: Enter the loan amount in dollars, interest rate as a decimal (5% = 0.05), and loan term in years. All values must be positive numbers.
