You are financing the vehicle using traditional financing, not leasing.Operating costs are estimated for a 5-year period.The TCO® calculations use the following set of assumptions: Note that TCO® is a comparative tool, not a predictive tool - your actual 5-year cost of owning a particular vehicle will vary depending on your personal circumstances such as your driving history and the number of miles you drive. For a used car, we calculate the years the vehicle has been driven using the nominal difference between the current calendar year and the vehicle's model year, and we assume that it was driven 15,000 miles during each of those years. In order to estimate certain mileage-dependent costs, we assume that vehicles will be driven 15,000 miles per year. The components of this TCO® calculator are car depreciation, interest on financing, taxes and fees, insurance premiums, fuel, maintenance, repairs, and any federal tax credit that may be available.
