How Auto Loan Calculations Work

Auto loan calculations are based on the loan amount, interest rate, and term. The most common calculation method is the amortization formula:

The formula calculates the fixed monthly payment that will pay off the loan over the specified term. The interest is calculated on the remaining balance each month.

Key Terms

• APR (Annual Percentage Rate) - The annual interest rate charged on the loan
• Loan Term - The length of time to repay the loan in years
• Monthly Payment - The amount paid each month
• Total Interest - The total amount paid in interest over the life of the loan

Worked Example

Let's calculate a $25,000 auto loan with a 4.5% APR over 5 years (60 months):

1. Convert APR to monthly rate: 4.5%/12 = 0.375% or 0.00375
2. Plug values into the formula:
   M = 25000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ]
3. Calculate the monthly payment: $452.34
4. Total interest paid: $1,734.40

This example shows that with a $25,000 loan at 4.5% APR over 5 years, you would pay approximately $452.34 per month with $1,734.40 in total interest.
