Long terms exist because they work: a 72-month loan is how a $38,000 car fits a $600 payment, and an 84-month loan is how a $45,000 one does. The finance office presents the term as a convenience. From the dealership’s side, it is the lever that moves more car into more driveways without moving the price, and most buyers never run the total.

Here is the total, with one example car, so you can see what each extra year costs and when it is a reasonable trade. All figures are examples; your rate and your car move them.
