How this is calculated
The amount financed is your vehicle price, plus sales tax and fees, minus your down payment and net trade-in (trade-in value minus what you still owe on it). If you owe more than the trade is worth, that negative equity is added to the new loan. The monthly payment uses the standard amortizing-loan formula at your APR ÷ 12. Sales tax is applied to price minus trade-in, which is how most regions give a trade-in tax credit — check your local rules.
