ORLANDO, Fla. – AAA has released the results of its annual ‘Your Driving Costs’ study, revealing a 1.96 percent increase in the cost to own and operate a sedan in the U.S. The average cost rose 1.17 cents to 60.8 cents per mile, or $9,122 per year, based upon 15,000 miles of annual driving. 
"Many factors go into the cost calculation of owning and operating a vehicle," said John Nielsen, AAA director of automotive engineering and repair. "This year, changes in maintenance, fuel and insurance costs resulted in the increase to just over 60 cents a mile."
Maintenance Costs Up 11.26 Percent
The costs associated with maintaining a vehicle had the single largest percentage increase from 2012 to 2013, growing by 11.26 percent to 4.97 cents per mile on average for sedan owners. AAA’s estimates are based upon the cost to maintain a vehicle and perform needed repairs for five years and 75,000 miles including labor expenses, replacement part prices and the purchase of an extended warranty policy. Driving the increase in maintenance costs are significant increases in labor and part costs for some models and a major increase in the price of extended warranty policies due to high loss ratios by underwriters.
Fuel Costs Up 1.93 Percent
Gasoline prices were relatively stable compared to the prior year, leading to a minimal fuel cost increase of 1.93 percent to 14.45 cents per mile on average for sedan owners. The average cost of regular grade fuel (used by most of the study vehicles) actually rose 3.84 percent, from $3.357 to $3.486 per gallon. However, AAA noted that several vehicles in the ‘Your Driving Costs’ study had small improvements in their fuel economy ratings, which partially offset the fuel cost increase. Fuel costs in the 2013 study were calculated using the national average price for regular, unleaded gasoline during the fourth quarter of 2012.
Tire Costs Remain Unchanged
The cost of tires did not change from 2012 to 2013, remaining at one cent per mile on average for sedan owners. The stable price is attributed to a leveling off of past increased costs for raw materials, energy and transportation from factories to distributors across the country.
Insurance Costs Up 2.76 Percent
Average insurance costs for sedans rose 2.76 percent (or $28) to $1,029 annually. Insurance rates vary widely by driver and driving record, issuing company and geographical region. AAA insurance cost estimates are based on a low-risk driver with a clean driving record. Quotes from five AAA clubs and insurance companies representing seven states showed across-the-board modest increases for all sedan sizes, with large cars having less of an increase than small- and medium-size sedans.
Depreciation Costs Rise .78 Percent
After seeing a drop in 2012, depreciation costs were up slightly in 2013, increasing .78 percent to $3,571 a year. This change may be a consequence of recovering new vehicle sales, resulting in more used cars available in the marketplace and thus the softening of the resale value of clean older models, AAA said.
AAA has published ‘Your Driving Costs since 1950. That year, driving a car 10,000 miles per year cost 9 cents per mile, and gasoline sold for 27 cents per gallon.
