How This Calculator Works
Calculation methodology and assumptions
Auto loan calculation for Texas. Texas's state sales tax of 6.25% is applied to the vehicle price minus trade-in value. Local taxes may add up to 2% more. Monthly payment uses standard amortization: P × [r(1+r)^n] / [(1+r)^n - 1].
Key State Information

Example Calculation
What does financing a $35,000 vehicle look like in Texas?
On a $35,000 vehicle with $5,000 down and a 6.5% APR for 60 months: your loan amount is $30,000, resulting in a monthly payment of approximately $587. Total interest over the loan: $5,219. Texas's combined sales tax of roughly 7.05% adds about $2,468, bringing your total cost to approximately $42,687.
Result: Choosing a shorter loan term increases the monthly payment but saves meaningfully on interest, while a longer term lowers the payment but adds interest over time. Always calculate the total cost — including Texas's sales tax — not just the monthly payment.
