How it came to be
AAA published its first 'Your Driving Costs' booklet in 1950 to give members an apples-to-apples view of what cars actually cost beyond the sticker. Runzheimer International commercialised vehicle cost analysis for corporate fleets starting in 1933. The discipline matured in the 1990s as leasing exploded — lessors had to model every cost component to set monthly payments. Today Vincentric, ALG, KBB and Edmunds all publish five-year TCO estimates, and consumer regulators in the EU require fuel-cost disclosures on every new-car window sticker.

The five big costs
Depreciation, fuel/electricity, insurance, maintenance/repairs and financing interest. AAA's annual study puts the average new car at roughly $12,000/year over five years — about $1,000/month before parking and tolls.
Fuel and energy
A 25-mpg car driven 12,000 miles a year on $3.50 gas costs $1,680/year. An equivalent EV at $0.15/kWh and 3.5 mi/kWh costs about $515/year — but home charging access matters enormously. Public DC fast charging can cost as much as gas.
Insurance
Driven by vehicle value, your driving record, ZIP code, age and credit. A new sports car for a young driver can run $4,000+/year; the same driver in a midsize sedan might pay $1,400. Get quotes before you buy — premiums vary 3–4x between models.
Maintenance and repairs
Toyota and Honda average $400–500/year for the first five years. German luxury averages $900–1,200/year and spikes once the factory warranty expires. Out-of-warranty Range Rover, Maserati and Bentley repairs commonly exceed the car's resale value.
Hidden costs
Tires for a performance car can cost $1,500–3,000 a set and only last 10,000–20,000 miles. Brake jobs on carbon-ceramic systems run $15,000+. Premium-fuel-only engines add 10–15% to every gas stop. Factor these in before buying.
