Calculate your car loan payment from the vehicle price, down payment, trade-in value, and sales tax. Use it before buying to see the monthly payment, total interest, and exactly how much you will finance.
How this is calculated
Sales tax is applied to the price and the amount financed equals price plus tax minus down payment and trade-in, then the standard loan amortization formula gives the monthly payment and total interest.
How to use
- Enter the vehicle price, your down payment, and any trade-in value.
- Enter the sales tax rate, annual interest rate, and term in months.
- Read the monthly payment, total interest, and amount financed.
Examples
- $30k, $3k down, $2k trade-in, 7% tax, 6% / 60 mo:
payment $523.92 - Amount financed:
$30,000 + tax − down − trade-in → $27,100
FAQ
- How is the amount financed calculated?
- Amount financed = vehicle price + sales tax − down payment − trade-in value. Sales tax is applied to the vehicle price.
- Does a trade-in reduce my loan?
- Yes. The trade-in value is subtracted from the price (along with your down payment) before the loan is calculated, lowering the amount you finance.
- How is sales tax handled?
- Sales tax is computed as price × tax rate and added to the amount financed, so you pay interest on the tax unless you cover it up front.
