1. What is the Auto Loan Interest Calculator?

This calculator determines the total interest you'll pay over the life of an auto loan using Bankrate's methodology. It helps borrowers understand the true cost of financing a vehicle.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The formula calculates the difference between total payments made and the original loan amount to determine total interest paid.

3. Importance of Interest Calculation

Details: Understanding total interest helps borrowers compare loan offers, evaluate refinancing options, and make informed financial decisions about vehicle purchases.

4. Using the Calculator

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