Where people go wrong

  • Taxing the full price and ignoring the trade-in credit.
  • Subtracting both the down payment and trade-in twice.
  • Comparing payments without total interest and term.

FAQ

60 or 72 months?

Longer terms lower the payment but raise interest and negative equity; compare total cost.

Is the trade-in taxed?

Most states tax price minus trade-in; a few differ, so check your DMV.

What about 0 percent?

Payment = loan divided by months, with zero interest; you may give up a rebate.
