r = APR ÷ 12 and n = term in months. Sales tax is usually financed into the loan, while your down payment and trade-in reduce the amount borrowed. A shorter term means higher payments but far less total interest.
What your car really costs
Your amount financed is the vehicle price plus sales tax, minus your down payment and any trade-in. That's amortized over the term at your APR to produce the monthly payment. The donut shows how much of your total goes to the car versus interest.
Watch how a shorter term or bigger down payment cuts total interest — often by thousands over the life of the loan.
