Different car types equal different costs
AAA calculated the average costs for six different car types based on the ownership costs in the study. It found that the average cost of all sedans -- the majority of cars on the road -- is 60.8 cents per mile or $9,122 annually, based on 15,000 miles of driving. Small sedans cost the least -- $6,967 annually. Four-wheel-drive sport utility vehicles cost the most -- $11,599 annually -- largely due to the fuel costs of those cars. Perhaps surprisingly, large sedans cost almost as much -- $11,248 -- as four-wheel-drive SUVs, while minivans, which often have about the same amount of passenger and cargo-carrying capability as many SUVs, averaged just $9,795.
Depreciation doesn't compensate
In last year's study, depreciation rates had slowed significantly, making cars worth more and partially offsetting the increases in ownership. According to the 2013 Your Driving Costs study, depreciation rose 0.78 percent to $3,571 annually on average. AAA attributed this to an increase of used cars available, which has softened resale values.
Next, for other ownership costs, we'll focus on the sedan as our example.
Maintenance costs see big rise
In terms of car-maintenance costs, the AAA study found that there were significant increases in the cost of labor and parts over the past year. As a result, average maintenance costs are up by 11.26 percent on average for sedan owners, the largest percent year-over-year increase, to 4.97 cents per mile. Included in that figure are the labor and parts costs to maintain and repair the car for five years and 75,000 miles as well as purchasing an extended warranty. AAA noted that figure also has increased due to increases in extended warranty prices -- the result of high losses by underwriters.
Car insurance costs more, too
While AAA notes that auto insurance rates vary widely due to numerous factors, car insurance is rising 2.76 percent to $1,029 annually for the average sedan owner over 2012. To arrive at its average, AAA used a hypothetical low-risk driver with a clean driving record and obtained quotes from five AAA clubs and insurance companies representing seven states.
Fuel costs rise marginally
While gas prices have continued to rise, fuel costs are up only slightly, partially offset by improvements in car fuel economy. The average cost for regular unleaded gasoline is up 3.84 percent, but due to miles-per-gallon improvements, fuel costs have risen just 1.93 percent to 14.45 cents per mile on average for sedan owners. For its calculation, AAA uses the national average for regular, unleaded gas in the fourth quarter of the prior year.
Tire costs stay stable
After an increase in the 2012 study, tire costs have remained stable this year, as manufacturing and shipping costs for tires have leveled off. The average sedan owner pays one penny per mile for tires.
