Long-haul freight no longer guarantees higher absolute profit: lower rates per mile now sit closer to rising variable cost, and additional miles can magnify losses when the rate decline exceeds the cost advantage of greater length of haul.
A Shift in Profitability
Historically, longer hauls carried a lower rate per mile but generated more total revenue and higher velocity. That made long-haul freight a dependable source of absolute margin.
KSMTA's client research showed that this relationship had changed. Fuel, driver wages, insurance, and other operating costs had risen across every length-of-haul range. Because long-haul rates are naturally lower, they sit especially close to variable cost per mile. When a rate falls below breakeven, every additional mile increases the loss.
State and provincial costs can also change the result. One client reported that operating in California added $0.06 per mile in fuel tax alone. The difference was large enough for KSMTA to adjust its activity-based costing model to account for non-toll miles traveled within each state.
The Tradeoff Between Miles and Rates
The assumption that a carrier can offset a lower rate with more miles must be tested rather than accepted.
In one monthly client review, average length of haul increased by 66 miles. The change generated an additional $46 of revenue per load, but also added $57 of cost, creating an $11 loss per load.
Sensitivity analysis showed that the carrier could reduce its rate by $0.01 for each 11-mile increase and maintain its existing profitability. A 66-mile increase could therefore support a rate reduction of approximately $0.06 per mile. The carrier's actual average rate fell by $0.10.
The decline was not an intentional price cut. It resulted from shifting capacity into longer-haul lanes. The example demonstrated why intuition is not enough when evaluating the relationship between rate and mileage.
Operational Inefficiencies
The historical benefits of long-haul freight also depended on velocity and lower support requirements. Those advantages have weakened.
Carriers operate at slower speeds because of safety concerns, and electronic logging devices have reduced operating flexibility. Slower movement and tighter hours-of-service constraints reduce the velocity that once helped long-haul freight overcome its lower rate per mile.
Competition and Market Change
Shippers have expanded hub-and-spoke distribution, placed facilities closer to consumers, and adopted predictive inventory systems. Those changes appear to have reduced the number of available long-haul lanes.
At the same time, carriers continue to bid aggressively because some drivers prefer longer trips. More carrier demand for a smaller supply of long-haul opportunities can suppress rates further.
Rethinking Long-Haul Strategies
OTR carriers need to reevaluate the historical bias toward long-haul freight. The analysis should determine:
- Current variable cost per mile.
- State- and province-specific cost differences.
- The rate reduction that can be absorbed for each increase in length of haul.
- The actual effect of transit time, loading delays, and operating speed.
- Whether competition has pushed a lane below breakeven.
Carriers that use a detailed model can identify where added miles still create value and where they merely multiply a thin or negative contribution. Without that distinction, long-haul freight can shift from a traditional profit source to a significant financial risk.
