1. The business problem
Why can a trucking company grow revenue and still make less money?
Freight revenue is easy to see and easy to grow: take another lane, add another customer. But cost does not grow at the same rate. Fuel moves with the market, empty miles creep up as networks stretch, and the freight that is easiest to win is often the least profitable.
This matters because carriers can end a year with more loads, more miles and less profit, and not know why until the margin has already slipped.
2. What the evidence can reveal
A carrier’s economics come from a few measures that need to be read together:
- Calculated Revenue and cost per loaded mile: the unit spread.
- Calculated Empty-mile share: miles that cost fuel, driver time and wear but earn nothing.
- Calculated Cost by category: fuel, driver pay, maintenance and fixed cost.
- Calculated Contribution by lane or customer: what each leaves after direct cost.
- Information gap What the totals hide: fuel-surcharge recovery, detention, customer terms and equipment utilization.
Many carriers track each of these, but rarely side by side, and rarely by lane.
3. Investigate the problem
In the synthetic carrier, freight revenue grew 7.0% and loaded miles grew 6.5%, but operating costs grew 11.6%. Operating profit moved from $1.80M to $1.28M. Illustrative
Calculated Fuel carried 43% of the cost increase (up 16.3%), and the empty-mile share rose from 15.2% to 16.3%. By lane, Cross-country spot grew miles 14.5% while its contribution fell 20.0%. The fastest-growing lane was the weakest one.
Hypothesis Spot freight often grows quickly because it is available when capacity is loose, and it often carries the highest empty miles and the thinnest recovery of fuel cost. The scenario puts a number on empty miles: a point of empty-mile share changes operating profit by about −$148K, more than a point of fuel price (−$50K).
