Formula Used

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

Monthly Payment Formula

M = P [ i(1 + i)ⁿ ] / [ (1 + i)ⁿ - 1 ]

Where:

M = Monthly payment
P = Principal loan amount (Purchase price - Down payment)
i = Monthly interest rate (Annual rate / 12)
n = Number of payments (Loan term in years × 12)

Total interest paid is calculated by multiplying the monthly payment by the number of payments and subtracting the principal loan amount.

Worked Example

Let's calculate a loan for a $30,000 car with a $3,000 down payment, 5-year term, and 4.5% annual interest rate.

Principal = $30,000 - $3,000 = $27,000
Monthly interest rate = 4.5% / 12 = 0.375%
Number of payments = 5 × 12 = 60
Monthly payment = $27,000 [ 0.00375(1 + 0.00375)⁶⁰ ] / [ (1 + 0.00375)⁶⁰ - 1 ] ≈ $474.50
Total interest = ($474.50 × 60) - $27,000 ≈ $1,647

This example shows that with these terms, you would pay approximately $474.50 per month with about $1,647 in total interest.
