Through Externality, Air pollution and Energy consumption

Fuel prices in the United States

In 2008, a report by Cambridge Energy Research Associates stated that 2007 had been the year of peak gasoline usage in the United States, and that record energy prices would cause an "enduring shift" in energy consumption practices. According to the report, in April fuel consumption had been lower than a year before for the sixth straight month, suggesting 2008 would be the first year US usage declined in 17 years. The total annual distance driven in the US began declining in 2006.

After Hurricane Katrina and Hurricane Rita, gas prices started rising to record levels. Increases in crude oil prices significantly predict the growth of real gross domestic product (GDP), but increases in natural gas prices do not. In August 2005, after Hurricane Katrina, spot market gas prices surged past $11 per gigajoule ($12 per million British thermal units), and by 22 September 2005, before Hurricane Rita's landfall, had risen to $14 per gigajoule ($15 per million British thermal units).

In the fifteen years prior to the 1973 oil crisis, gasoline prices in the U.S. had lagged behind inflation.

A May 2004 report by the Government Accountability Office (GAO) on petroleum industry mergers from the 1990s to 2004 found that the mergers increased companies' ability to influence prices.

In early 2020, the national average gas price dropped to $1.73 per gallon. In 2021, it rose to $3.01/gallon, and by June 2022 reached over $5/gallon, with some areas reporting $6/gallon. Prices later declined but fluctuated through late 2022.

In March 2026, average gasoline prices in the United States rose above $4 per gallon for the first time since 2022, driven largely by disruptions to global oil supply.

Factors affecting gasoline prices

According to the Energy Information Administration (EIA), as of March 2022, factors affecting the price of gasoline in the United States include the price of crude oil, costs and profits related to refining, distribution, marketing, and taxes. Higher octane levels cost more, with premium grade averaging about 68 cents per gallon more than regular grade in 2021. From 2012 through 2021, crude oil represented 54.8% of the average $2.80/gallon price, taxes 17%, distribution and marketing 14.3%, and refining 14%. In 2021, crude oil accounted for 53.6%, taxes 16.4%, distribution and marketing 15.6%, and refining 14.4%.

Crude oil

Crude oil is the main factor affecting gasoline and diesel prices. Exploration, extraction, and transport costs contribute to pricing. Between 2004 and 2008, global demand increases raised oil prices from $35 to $140 per barrel ($220 to $880/m3), causing a corresponding rise in gas prices. OPEC production decisions and speculation in oil markets also influence gasoline prices.

Marketing and distribution

Distribution and marketing costs cover transportation of crude oil to refineries and gasoline to retailers, as well as brand marketing expenses.

In the United States, marketing and distribution costs represent a significant component of the retail price of gasoline, typically accounting for 11% to 15% of the total cost per gallon. These expenses encompass the logistics of transporting crude oil to refineries and the subsequent delivery of refined products to retail outlets via pipelines and tanker trucks. According to the Energy Information Administration (EIA), this share stood at 15.6% in 2021, though it can fluctuate relative to the price of crude oil; during the global supply disruptions of 2026, for example, the relative share of distribution costs was estimated at 11% as the cost of raw crude increased.

Retailer profit margins are also included within this category. While gas stations typically average a gross margin of 30 to 35 cents per gallon, these margins are often inversely correlated with crude oil price trends: margins tend to contract when oil prices surge rapidly and expand when prices decline.

Taxes

The United States federal excise tax on gasoline is 18.4 cents per gallon and 24.4 cents per gallon for diesel fuel. Proceeds from the tax partly support the Highway Trust Fund. The federal tax was last raised on October 1, 1993, and is not indexed to inflation, which increased 122% from October 1993 until November 2025. On average, as of April 2019, state and local taxes and fees add 34.24 cents to gasoline and 35.89 cents to diesel, for a total US volume-weighted average fuel tax of 52.64 cents per gallon for gas and 60.29 cents per gallon for diesel.

Other factors

Weather events, conflicts, and legislation for cleaner-burning fuels can raise prices. Gasoline costs also follow seasonal demand patterns, typically increasing in summer. U.S. consumption has generally risen since 1950, with notable dips during the introduction of corporate average fuel economy standards, the 1979 energy crisis, the early 1990s recession and Gulf War, and the Great Depression.
