Average Marginal Trucking Costs per Mile, United States, 2008-2013
Trucking is a highly competitive industry since the barriers of entry are low. The two most significant operating costs of trucking are fuel (38%) and wages and benefits (35%). Jointly, they account for about 73% of all costs. There is very little flexibility in this cost structure, implying that fluctuations in energy prices cannot be mitigated well and impact directly the low profit margins of the industry (less than 10%).
