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 ($18,000)
r = Monthly interest rate (annual rate / 12)
n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment required to pay off the loan over the specified term.

Example Calculation

Let's calculate the monthly payment for a $18,000 loan with a 5% annual interest rate over 5 years:

Principal (P) = $18,000
Annual interest rate = 5% or 0.05
Monthly interest rate (r) = 0.05 / 12 ≈ 0.004167
Number of payments (n) = 5 years × 12 = 60 months

Plugging these values into the formula:

Monthly Payment = $18,000 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)

Monthly Payment ≈ $352.45

So, for this example, the monthly payment would be approximately $352.45.

Can I pay off my auto loan early?: Yes, you can pay off your auto loan early without penalty. However, check with your lender for any prepayment penalties or fees.
What happens if I miss a payment?: Missing a payment can result in late fees, higher interest charges, and potentially damage your credit score. Contact your lender immediately if you're having trouble making payments.
