1. What is Auto Loan Interest?

The total interest paid on an auto loan represents the additional cost of borrowing money to purchase a vehicle. It's calculated by multiplying the number of payments by the monthly payment amount and subtracting the original loan principal.

2. How Does the Calculator Work?

The calculator uses the auto loan interest formula:

Where:

• \( n \) — Number of payment periods (months)
• \( PMT \) — Monthly payment amount
• \( P \) — Principal loan amount

Explanation: This formula calculates the total amount paid over the life of the loan and subtracts the original amount borrowed to determine just the interest portion.

3. Importance of Calculating Total Interest

Details: Understanding the total interest helps borrowers compare loan offers, evaluate the true cost of financing, and make informed decisions about loan terms and down payments.

4. Using the Calculator

Tips: Enter the loan term in months, the monthly payment amount, and the original loan amount. All values must be positive numbers.
