State Gas Prices by Year, 1970–2024
In 2024, the average price of gasoline ranged from $2.88 a gallon in Texas to $4.73 in Hawaii, with a U.S. average of $3.29. This page lists every state’s annual average for every year since 1970, at the price paid at the time and adjusted to 2025 dollars.
About these figures
The figures are the U.S. Energy Information Administration’s State Energy Data System (SEDS) prices for motor gasoline: the average of all grades sold in the state over the year, with federal, state and local taxes included. SEDS publishes them in dollars per million Btu; they are converted to dollars per gallon with the EIA’s heat content for gasoline in each year. Because they average all grades and the whole year, they are a different measure from the weekly regular-grade prices shown elsewhere on the site, and the two can differ in either direction.
Two limits apply. Values before 2000 are approximate. After 2010, for the 42 jurisdictions without an EIA weekly series, SEDS estimates each year from the change in the state’s region, so year-to-year moves in those states mostly reflect the region (see the methodology). The latest year is 2024; the EIA publishes each year’s figures about eighteen months after it ends. For this week’s prices see gas prices by state.
Adjusted for inflation, Hawaii had the highest average in 49 of the 55 years.
