Gas Prices Decline Nearly 20% in Some States, Stay High in Others – 2023 Study


Gas prices have been on the decline since their all-time high in summer 2022. While the average last summer across the U.S. hit a record $5.00 per gallon, the current average has come down to $3.27 per gallon. But in some states, high prices have been more stubborn than in others. Demand, state legislation, transport and other factors drive gas prices up and down nationwide.

To find where gas prices have gone down the most – and where they have remained highest – SmartAsset ranked the 50 states by the biggest declines in average gas prices over the last year.

Key Findings

  • Utah sees an 18.6% drop in gas prices over the last year. The Beehive State saw the biggest reprieve, with prices down 72 cents over the last year for a current average of $3.19 per gallon. Indiana (-15.4%) and Arizona (-14.1%) placed second and third.
