How to use the auto loan calculator
- Enter the vehicle price, down payment, trade-in value and anything still owed on it.
- Add your local sales tax rate and dealer fees.
- Set the loan rate and term to get the monthly payment and the true total cost.
Amount financed, explained
You do not finance the sticker price. Sales tax - figured on the price after trade-in credit, the way most states do it - plus fees join it, then the down payment and net trade-in (value minus what you still owe) come off. The remainder is the amount financed, and interest accrues on that. A few states tax the full price before trade-in credit, so treat the result as a close estimate and confirm with the dealer sheet.
Worked example
A $32,000 car with $4,000 down, a $6,000 trade-in owned outright, 7% tax and $500 fees finances about $24,320. At 7% over 5 years that is roughly $482 a month.
