  "textContent": "Key findings\n\nThe average price for a gallon of regular gasoline in Washington is $5.57, which is $1.10 per gallon above the national average of $4.48.\nWashington drivers pay 49.4 cents per gallon in state gas taxes, ranking 4th highest in the country.\nThe average residential electricity rate in Washington is 14.4 cents per kWh, compared to the national residential average of 18.8 cents per kWh.\nDriving electric in Washington could save approximately $2,641 per year in fuel costs compared to a gasoline vehicle.\nOver the past month, gas prices in Washington have remained relatively stable.\n\n\nWhat are current gas prices in Washington?\nThe average price for a gallon of regular gasoline in Washington is currently $5.57. That is $1.10 per gallon higher than the national average of $4.48, which means Washington drivers are paying roughly 24.5% more than the typical American motorist.\nFor a vehicle with a standard 14-gallon fuel tank, a full fill-up in Washington costs approximately $77.98. At the national average price, that same fill-up would cost $62.65. That means drivers in this area spend about $15.33 more every time they fill up.\nGas prices vary based on several factors, including crude oil costs, refining capacity in the region, transportation and distribution expenses, local competition among gas stations, and state and federal tax rates. Washington also sees seasonal price fluctuations, with prices typically rising in the spring and summer driving months and falling during the winter.\nHow much is gas tax in Washington?\nWashington has a state gas tax of 49.4 cents per gallon. That ranks 4th highest among all 50 states and the District of Columbia. This is well above the national median and is a significant factor in why gas prices in Washington tend to run higher than in many other states.\nOn top of the state tax, drivers in Washington also pay the federal gas tax of 18.4 cents per gallon, bringing the combined tax burden to 67.8 cents for every gallon of regular gasoline purchased. State gas taxes fund road construction and maintenance, bridge repair, and other transportation infrastructure projects. Some states adjust their gas tax annually based on fuel prices or inflation, while others require legislative action to change the rate.\nHow have gas prices changed in Washington?\nOver the past 30 days, gas prices in Washington have remained relatively stable. Looking at a wider window, prices over the last 12 weeks have trended upward by about $1.05 per gallon.\nGas prices across the United States are influenced by global crude oil markets, refinery output, seasonal demand, and geopolitical events. In Washington, regional factors like proximity to refineries, pipeline infrastructure, and local supply and demand conditions add another layer of price variation. Prices tend to peak between Memorial Day and Labor Day when driving demand is highest, and they often dip in the fall and winter months.\nGas price trend in Washington\n\n\n\nHow do gas and electricity costs compare in Washington?\nThe average residential electricity rate in Washington is 14.4 cents per kilowatt-hour (kWh). That is below the national average residential electricity rate of 18.8 cents per kWh. The national average electricity rate across all sectors (residential, commercial, and industrial) is 14.2 cents per kWh.\nThese electricity rates matter because they directly affect how much it costs to charge an electric vehicle at home. Most EV owners charge at home overnight using standard residential electricity, so the residential rate is the most relevant number for comparing fuel costs between gas and electric vehicles.\nHere is how the cost per mile breaks down in Washington:\n\nGasoline vehicle (average 25.4 MPG): $0.219 per mile\nElectric vehicle (average 0.30 kWh per mile): $0.043 per mile\nDriving electric in Washington is approximately 80% cheaper per mile than driving on gasoline.\n\nIs it cheaper to drive electric in Washington?\nBased on the average driver covering 15,000 miles per year, here is what annual fuel costs look like in Washington:\n\nGasoline vehicle: approximately $3,289 per year (at $5.57 per gallon and 25.4 MPG average)\nElectric vehicle: approximately $648 per year (at 14.4 cents per kWh and 0.30 kWh per mile)\n\nThat is an estimated annual savings of $2,641 by driving electric in Washington. Over a typical 5-year ownership period, that adds up to roughly $13,207 in fuel savings alone, not counting the additional maintenance savings that come with an electric vehicle (no oil changes, fewer brake replacements, and no transmission service).\nThese estimates assume home charging at residential electricity rates. Public DC fast charging is typically more expensive, ranging from $0.30 to $0.60 per kWh depending on the network and location.
