Idaho gas prices have decreased for the second consecutive week, bringing the state average to $4.87 per gallon. Nationally, gasoline prices dropped by two cents this week.
Why it matters
The decline in local fuel costs follows a broader national trend, though Idaho remains the state with the seventh most expensive fuel in the country. Crude oil prices, currently trading near $94 per barrel, remain a key factor influencing these retail price changes.
The average price of a gallon of gasoline in Idaho is $4.87, representing a seven-cent decrease from last week. Idaho remains well above the national average of $4.34, with California holding the highest state price at $6.28.
The details
Regional variations persist across the state, with Rexburg recording the highest price at $4.97 per gallon, followed by Twin Falls at $4.94 and Boise at $4.93. While current weekly trends show relief for consumers, prices remain $1.42 higher than they were one year ago.
Timeline
One year ago, Idaho gas prices were $1.42 lower than current levels.
One month ago, Idaho gas prices were nine cents lower than current levels.
Last week, Idaho gas prices were seven cents higher than current levels.
Current week marks the second consecutive week of falling gas prices.
Market Landscape
This decline follows the 2026 domestic fuel price fluctuations that have defined regional cost disparities across the United States. Idaho continues to navigate these volatile market shifts as it maintains its position as the state with the seventh highest fuel costs in the nation.
Drivers in Idaho will see slightly lower prices at the pump this week, though costs remain significantly higher than they were this time last year. Fluctuations in global crude oil prices mean that current savings could be short-lived if commodity costs begin to climb again.
The takeaway
While Idaho gas prices have trended downward for two weeks, the state's average remains significantly elevated compared to the national baseline. Consumers should continue monitoring regional price differences, as fluctuations in crude oil markets remain a primary driver for retail costs.
