Formula Used

The monthly payment is calculated using the standard auto loan formula:

M = P [i(1 + i)^n] / [(1 + i)^n - 1]

Where:

M = Monthly payment
P = Principal loan amount (Purchase price - Down payment)
i = Monthly interest rate (Annual rate / 12)
n = Number of payments (Loan term in years × 12)

The Texas sales tax is calculated as 6.25% of the vehicle's purchase price.

Worked Example

Let's calculate a loan for a $30,000 vehicle with a $3,000 down payment, 4.5% annual interest rate, and 5-year term.

Principal = $30,000 - $3,000 = $27,000
Monthly interest rate = 4.5% / 12 = 0.375%
Number of payments = 5 × 12 = 60
Monthly payment = $27,000 [0.00375(1.00375)^60] / [(1.00375)^60 - 1] ≈ $521.34
Total interest = ($521.34 × 60) - $27,000 ≈ $1,880.40
Texas sales tax = $30,000 × 6.25% = $1,875

Your estimated monthly payment would be $521.34, with $1,880.40 in total interest and $1,875 in Texas sales tax.
