This calculator provides an estimate. Actual payments may vary based on your lender's specific terms and Oregon state regulations.

Formula Used

The monthly payment is calculated using the standard auto loan 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 months)

The total interest paid is calculated by multiplying the monthly payment by the number of payments and subtracting the principal loan amount.

Worked Example

Let's calculate a monthly payment for a $25,000 loan at 4.5% annual interest over 60 months (5 years):

Principal (P) = $25,000
Annual interest rate = 4.5% → Monthly rate (r) = 4.5%/12 = 0.00375
Number of payments (n) = 60

Plugging these into the formula:

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

Monthly Payment ≈ $456.28

Total interest paid over 5 years would be approximately $1,848.40.
