Semi / Dry Van Cost Per Mile in Alaska

Diesel fuel in Alaska currently averages $5.36 per gallon, which includes a state fuel tax of 8.9¢ per gallon. This relatively low fuel tax helps keep your semi / dry van fuel cost per mile below the national average.

Average commercial semi / dry van insurance in Alaska runs approximately $400/month. This moderate premium is typical for the region and should be reviewed annually to ensure you're not overpaying.

Semi trucks average 5.5–7.5 MPG, making fuel the largest single expense — typically 30–40% of total CPM. At these consumption rates, even a $0.20/gallon price difference between states changes your CPM by $0.03–$0.04/mile, which compounds to $300–$450/month at 11,500 miles.

Alaska's extreme distances and harsh climate make fuel logistics and maintenance critical cost factors. Winter operations require cold-weather additives, block heaters, and increased idle time, all of which push CPM higher than the lower-48 average.

Semi insurance premiums are the highest of any equipment class, reflecting the higher liability exposure and cargo values. Tire costs ($0.04–$0.06/mile), DEF fluid, and DPF maintenance add meaningful variable costs that lighter equipment classes don't face.
