Formula Used

The monthly payment for an auto loan is calculated using the standard 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 on both the original principal and the interest that accumulates over the life of the loan.

Worked Example

Let's calculate a $25,000 auto loan at 5.5% annual interest for 5 years:

Principal (P) = $25,000
Annual interest rate = 5.5% or 0.055
Monthly interest rate (r) = 0.055 / 12 ≈ 0.004583
Number of payments (n) = 5 × 12 = 60

Plugging these into the formula:

Monthly Payment = $25,000 × (0.004583(1 + 0.004583)^60) / ((1 + 0.004583)^60 - 1)

Monthly Payment ≈ $478.50

Total interest paid over 5 years would be approximately $3,480, making the total cost of the loan $28,480.
