The Real Cost of Driving in America

01 Introduction

Transportation is the second-largest annual expenditure for American households, trailing only housing. In 2023, the average U.S. household spent $13,174 on transportation, representing 17.1% of total expenditures. Of that, gasoline (BLS's "Gasoline" line) accounted for $2,449.

Yet the actual fuel cost for any individual driver depends on three variables that differ dramatically from person to person: how far you drive, how efficient your vehicle is, and what you pay for fuel. This article examines each variable using exclusively U.S. government data to show what driving really costs in America.

Every statistic, chart, and table in this article is sourced from a federal agency or DOE national laboratory: the Environmental Protection Agency (EPA), the Energy Information Administration (EIA), the Federal Highway Administration (FHWA), the Bureau of Labor Statistics (BLS), and Oak Ridge National Laboratory (operated for the Department of Energy). No industry estimates, proprietary models, or third-party data are used.

02 How Much Americans Drive

In 2022, motor vehicles in the United States traveled a combined 3.196 trillion miles. Light-duty vehicles (passenger cars, SUVs, vans, and light trucks) accounted for approximately 2.823 trillion of those miles, or 88% of total vehicle miles traveled (VMT).

FHWA's own published figures put the average at 10,952 miles per vehicle per year, dividing total light-duty VMT by the 257.7 million registered light-duty vehicles in the U.S. However, actual individual mileage varies widely. The EPA uses 15,000 miles per year for its annual fuel cost label calculations.

Light-duty vehicles' dominance looks different depending on whether you measure miles or energy. They account for 88% of VMT in 2022, but only about 57% of total U.S. transportation energy use in 2019 (the most recent year in this data source, measured in gasoline-gallon equivalents across all fuels and modes), two different years and two different measures. The energy total includes aviation, rail, water and pipeline transport, which do not appear in road-vehicle mileage statistics, so no mileage share is given for them here.

03 Fuel Prices Over Time

Gasoline prices are the most volatile component of driving cost. The national annual average price of regular-grade gasoline has ranged from $1.03 per gallon in 1998 to $3.95 per gallon in 2022, a nearly four-fold difference within three decades.

Prices are not uniform across the country. In 2025, the West Coast (PADD 5) averaged $4.09 per gallon while the Gulf Coast (PADD 3) averaged $2.68 per gallon, a difference of $1.42 per gallon, or 53%. For a driver consuming 500 gallons per year, this regional spread translates to a $709 annual cost difference from geography alone.

Gasoline expenditures for the average American household surged 44% in 2022 to approximately $2,805, before falling 12.7% in 2023 to approximately $2,449 as the national average price fell from $3.95 to $3.52.

04 Fuel Economy Trends

The EPA has tracked the real-world fuel economy of new light-duty vehicles since 1975 through its Automotive Trends Report. Over 50 model years, fleet-average fuel economy has more than doubled, from 13.1 MPG in 1975 to an estimated 27.2 MPG in model year 2024.

The series has three phases. From model year 1975 to 1987, fuel economy rose from 13.1 to 22.0 MPG. From 1988 to 2004 it declined to 19.3 MPG. Since 2005 it has risen to 27.2 MPG in model year 2024. During the decline, the mix of new vehicles moved toward SUVs and light trucks; this article does not test the causes of any phase.

Without battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs), the 2024 fleet average would have been 1.7 MPG lower. Truck SUVs, now representing 50% of all new vehicle production, reached 25.7 MPG in model year 2024, an increase of 1.0 MPG from 2023.

05 Calculating Your Annual Fuel Cost

Annual fuel cost is the product of three factors: miles driven, vehicle fuel economy, and fuel price. The fundamental formula is straightforward arithmetic:

For example, a vehicle rated at 25 MPG driven 12,000 miles per year at $3.30 per gallon costs $1,584 annually in fuel: (12,000 ÷ 25) × $3.30 = $1,584.

The interactive matrix below shows how annual fuel cost varies across a range of fuel economies (15 to 50 MPG) and fuel prices ($2.00 to $5.00/gal) at a fixed 12,000 miles per year. The relationship is non-linear: improving from 15 to 25 MPG saves far more money than improving from 35 to 45 MPG at any given fuel price.

06 City vs Highway Driving Impact

EPA rates every vehicle with separate city and highway fuel economy numbers. City driving is consistently less fuel-efficient than highway driving due to frequent acceleration, idling, and lower average speeds. The EPA's standard test cycle assumes 55% city and 45% highway driving for combined ratings.

The gap between city and highway fuel economy varies by vehicle type and powertrain. In the EPA class averages charted below, highway fuel economy is 19% to 33% higher than city fuel economy. For a vehicle rated at 25 MPG city and 33 MPG highway, an all-city driver versus an all-highway driver would see a fuel cost difference of over $380 per year at 12,000 miles and $3.30/gal.

For individual drivers, the city/highway split is one of the most controllable variables affecting fuel cost. Commuters in dense urban areas with heavy stop-and-go traffic will experience costs closer to the city rating, while long-distance highway commuters will approach the highway rating. The EPA's default 55/45 city/highway split is a national average and may not reflect individual patterns.

07 The Full Picture

The cost of driving in America is shaped by the interaction of three government-measurable factors: total miles driven (FHWA), fuel prices (EIA), and vehicle efficiency (EPA). For the average American household, gasoline represents approximately 18.6% of total transportation spending and 3.2% of total household expenditures.

Over a five-year period at the 2024 national average price of $3.30/gal, a vehicle achieving the model year 2024 new-vehicle average of 27.2 MPG driven 12,000 miles per year would consume approximately 2,206 gallons and cost $7,289 in fuel. The same vehicle at 2022 peak prices ($3.95/gal) would cost $8,716, an additional $1,427 for the same driving.

Fuel is only one piece of the real cost of driving. In 2024, the average household spent $1,993 on vehicle insurance, about 83% of what it spent on gasoline that same year ($2,411).
