Diesel price breakdown by cost composition in the U.S. 2020-2025
Crude oil is the greatest cost component determining diesel retail prices in the United States. In February 2025, 49 percent of the diesel retail price was set by crude oil costs. That month, one gallon of diesel sold for an average of 3.68 U.S. dollars. U.S. diesel prices have generally stagnated in early 2025.
Fuel consumption remains high despite higher prices
Diesel and gasoline prices have experienced significant fluctuations over the past decades. In 2024, the average gasoline price stood at 3.3 U.S. dollars per gallon, a decrease from the 2022 peak but still higher than early 2000s levels. Despite these changes, U.S. gasoline consumption has remained high, averaging around 8.5 million barrels per day in 2024, with seasonal variations affecting demand.
Tax impact on fuel costs across states
Taxes play a significant role in determining fuel prices, with state-level differences creating notable price variations across the country. As of 2023, the average state tax for gasoline was 30.5 U.S. cents per gallon, while diesel faced a slightly higher average tax of 33.15 U.S. cents. These taxes contribute to the overall retail price and are often reinvested in road infrastructure. California, for instance, imposes some of the highest gasoline taxes in the country, reaching 68.1 U.S. cents per gallon in January 2024, which significantly impacts the state's fuel prices.
