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 / 12 / 100)
n = Number of payments (loan term in years × 12)

This formula accounts for the interest charged on the outstanding loan balance each month, resulting in a fixed monthly payment that includes both principal and interest.

Worked Example

Let's calculate the monthly payment for a $25,000 auto loan with a 4.5% annual interest rate and a 5-year term.

Principal (P) = $25,000
Annual interest rate = 4.5%
Monthly interest rate (r) = 4.5% / 12 / 100 = 0.00375
Loan term in months (n) = 5 × 12 = 60

Plugging these values into the formula:

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

Monthly Payment ≈ $454.23

This means you would pay approximately $454.23 per month for 60 months to repay the $25,000 loan.
