How the amount financed is built

The loan covers the vehicle price minus your down payment and trade-in credit, plus sales tax and title/registration fees when they're rolled in. Most states charge sales tax on the price after the trade-in credit, which this calculator assumes — a few (like California) tax the full price, so check your state.

Keeping the total cost down

Dealers quote monthly payments, but the number to compare is total cost. A longer term (72–84 months) lowers the payment while raising total interest, and can leave you owing more than the car is worth. A common rule of thumb: 20% down, a term of 48–60 months, and total vehicle expenses under 10–15% of take-home pay.
