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 ($4000)
r = Monthly interest rate (Annual rate ÷ 12 ÷ 100)
n = Number of payments (Loan term in years × 12)

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

Worked Example

Let's calculate the monthly payment for a $4000 loan with a 5% annual interest rate over 5 years:

Convert the annual interest rate to a monthly rate: 5% ÷ 12 = 0.4167% or 0.004167 in decimal form.
Calculate the number of payments: 5 years × 12 = 60 months.
Plug the values into the formula:

Monthly Payment = $4000 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)
Calculate the result: $4000 × (0.004167 × 1.004167^60) / (1.004167^60 - 1) ≈ $80.25

So, with these parameters, your monthly payment would be approximately $80.25.
