About gas prices in Alaska
- Regular gas in the West Coast outside California is 62¢ a gallon above the US average of $4.15 this week.
- The EIA groups Alaska with the other states in the West Coast outside California. Prices vary between states and towns in a region, mostly because of state gas taxes, so check the price at your station and type it in.
- Premium usually costs 90¢ to $1 more a gallon than regular. Most cars run fine on regular; only use premium if your owner’s manual says it is required.

Prices: U.S. Energy Information Administration (EIA), Weekly Retail Gasoline and Diesel Prices, week of 2 November 2026, in dollars per gallon including taxes, updated every week. The EIA publishes nine states on their own; other states show their region’s average. Prices at your station will differ, and your real fuel economy depends on speed, traffic, load and weather, so treat the result as an estimate.
About the Gas Cost Calculator
The Gas Cost Calculator works out how much fuel a trip will use and what it will cost. Enter the distance, your car’s fuel economy and the gas price, tick round trip if you are coming back, and split the cost between the people in the car. The price starts from the latest weekly average published by the US Energy Information Administration, for regular, midgrade, premium or diesel, and every state has its own page with this week’s price. The Gas mileage tab works out your car’s real mpg from a fill-up, and the calculator also works in kilometres and litres per 100 km.
How to use it
- 1 Enter the one-way distance of your trip, and tick “Round trip” if you are driving back.
- 2 Enter your car’s fuel economy, or tap a vehicle type for a typical figure.
- 3 Keep this week’s average gas price, tap another fuel grade, or type the price at your station.
- 4 Enter how many people are sharing the cost, then read the total and the cost per person.
Frequently asked questions
How much is gas in Alaska?
The EIA publishes a weekly average for the West Coast outside California rather than Alaska alone. In the week of 2 November 2026 it was: Regular $4.77, Midgrade $5.19, Premium $5.43 and Diesel $6.58 a gallon. Prices at your local station can be higher or lower.
How much does it cost to drive 100 miles in Alaska?
About $19.08 in a car that gets 25 miles per gallon: 100 ÷ 25 = 4 gallons at $4.77. A 50 mpg hybrid would spend $9.54, and a pickup truck at 19 mpg about $25.11.
How much does a 500-mile road trip cost in gas in Alaska?
At $4.77 a gallon, 500 miles costs about $95.42 in a 25 mpg car (20 gallons). Double it for the drive home, or tick “Round trip” in the calculator.
How do I calculate the gas cost of a trip?
Divide the distance by your car’s miles per gallon to get the gallons you need, then multiply by the price per gallon. A 300-mile trip in a 30 mpg car uses 10 gallons; at $3.50 a gallon that is $35.
How much gas does it take to drive 100 miles?
It depends on fuel economy: 4 gallons at 25 mpg, about 3.3 gallons at 30 mpg and 2 gallons in a 50 mpg hybrid. Multiply by the gas price for the cost.
How do I work out my car’s gas mileage?
Fill the tank and reset the trip meter. Drive as normal, then fill up again and note the gallons. Divide the miles on the trip meter by those gallons: 320 miles on 11.2 gallons is 28.6 mpg. Use the Gas mileage tab to do it for you.
How do I convert mpg to L/100 km?
Divide 235.21 by the mpg (US gallons). 30 mpg is 7.8 L/100 km, and 8 L/100 km is 29.4 mpg. The calculator converts automatically when you switch units.
How do I split gas money for a road trip?
Work out the total fuel cost for the whole trip, including the drive back, and divide by the number of people in the car. Some groups leave the driver out of the split as thanks for driving.
How often are the gas prices updated?
Every week. The EIA surveys gas stations every Monday and publishes national, regional and state averages the same day; the calculator picks them up on Tuesday.
