Formula Used

The monthly payment for an auto loan is calculated using the standard loan payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Principal loan amount i = Monthly interest rate (annual rate / 12) n = Number of payments (loan term in months)

Where:

P is the principal loan amount
i is the monthly interest rate (annual rate divided by 12)
n is the number of payments (108 for 9 years)

The total interest paid is calculated by subtracting the principal from the total of all monthly payments.

Worked Example

Let's calculate a 108 month auto loan with these parameters:

Loan amount: $25,000
Annual interest rate: 5%
Loan term: 9 years (108 months)

Using the formula:

i = 0.05 / 12 = 0.0041667 n = 108 M = 25000 [ 0.0041667(1 + 0.0041667)^108 ] / [ (1 + 0.0041667)^108 - 1 ] M ≈ $276.32

Total interest paid: $276.32 × 108 - $25,000 = $2,443.04

Total loan cost: $25,000 + $2,443.04 = $27,443.04

Frequently Asked Questions

What is a 108 month auto loan?

A 108 month auto loan is a car financing option that spans 9 years, offering lower monthly payments compared to shorter-term loans. It's ideal for buyers who want to pay off the loan over a longer period.

How does the interest rate affect my monthly payment?

A higher interest rate will increase your monthly payment and total interest paid over the life of the loan. Conversely, a lower rate will result in smaller monthly payments and less total interest.
