|Variable costs||Fixed costs||Total costs|
NOTES: Data may not add to total because of independent rounding. Data are the cost per mile based on 15,000 miles per year and a composite of three current model American automobiles. Variable costs include fuel, maintenance, and tires. Fuel costs are based on a late year average price per gallon of regular unleaded gasoline. Fixed costs (ownership costs) include insurance, license, registration, taxes, depreciation, and finance charges.
