Formula Used

The monthly payment for an auto loan is calculated using the following 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 years × 12)

This formula accounts for the interest on the loan balance each month, providing an accurate estimate of your monthly payments.

Worked Example

Let's calculate a loan with these parameters:

Loan amount: $25,000
Annual interest rate: 4.5%
Loan term: 5 years

Using the formula:

Monthly interest rate = 4.5% / 12 = 0.375% Number of payments = 5 × 12 = 60 M = 25000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ] M ≈ $452.38

Your estimated monthly payment would be $452.38, with a total interest of $1,734.40 and a total cost of $26,734.40.
