Formula Used

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

Loan Payment Formula

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years × 12)

This formula accounts for the interest you'll pay over the life of the loan, giving you an accurate monthly payment estimate.

Worked Example

Let's calculate the monthly payment for a $25,000 loan at 4.5% annual interest over 5 years.

Example Calculation

Principal (P) = $25,000

Annual Interest Rate = 4.5% or 0.045

Monthly Interest Rate (r) = 0.045 / 12 ≈ 0.00375

Number of Payments (n) = 5 years × 12 = 60 months

Monthly Payment = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)

Monthly Payment ≈ $456.23

With this example, you'd pay approximately $456.23 per month to pay off the loan in 5 years.
