Formula Explained
The total interest paid on an auto loan is calculated using the following formula:
Total Interest Paid Formula
Total Interest = (Loan Amount × Annual Interest Rate × Loan Term) / 12
Where:
- Loan Amount = The total amount borrowed
- Annual Interest Rate = The annual percentage rate (APR) expressed as a decimal
- Loan Term = The length of the loan in years
This formula calculates the total interest by multiplying the loan amount by the annual interest rate and the loan term, then dividing by 12 to convert the annual rate to a monthly rate.
Worked Example
Let's look at an example to understand how this works in practice.
Example Scenario
Loan Amount: $25,000
Annual Interest Rate: 5.5%
Loan Term: 5 years
Using the formula:
Total Interest = ($25,000 × 0.055 × 5) / 12 = $825.83
This means you would pay approximately $825.83 in interest over the life of the loan.
