Most new car purchasers are concerned mostly with the out-of-the-door price of the vehicle in making the purchase decision, but a more important factor to consider could be the cost to own it long-term.

To help customers to figure out the “total cost of ownership” of a vehicle, Kelley Blue Book (KBB) came up with a formula to calculate how much it costs to own for the first five years. The calculation draws data from eight different categories, including fuel, insurance, state fees, maintenance, repairs, depreciation, and insurance.

At the 2012 Chicago Auto Show, KBB presented this year’s Total Cost of Ownership Awards. Kia and Audi took the honor of being selected as the best brand and best luxury brand, respectively. There are 21 other awards went to individual segments.
