The lowest monthly payment is not always the cheapest option.

A longer term reduces what you pay each month but usually increases the total interest you pay over the life of the loan. An origination fee adds cost even when it's not reflected in the monthly payment. Compare the True total cost column — that's the real price of each offer.
