Semi / Dry Van Cost Per Mile in Mississippi

Diesel fuel in Mississippi currently averages $4.83 per gallon, which includes a state fuel tax of 18.0¢ 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 Mississippi runs approximately $380/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.

Mississippi's I-55 and I-20 corridors carry Gulf Coast freight north and east. Lower cost of living and moderate regulations keep operating overhead manageable, though insurance rates are above the national 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.
