Revenue Per Mile (RPM).
Total revenue divided by total miles driven; the headline number quoted in spot-market and contract pricing, but only meaningful when compared to CPM.
What it is
Revenue Per Mile (RPM) is total revenue (line-haul + fuel surcharge + accessorials) divided by total miles driven, including deadhead. It is the headline number quoted in every spot-market lane discussion ($2.50/mile, $3.00/mile) and the basis on which contract carriers negotiate dedicated lanes.
ATRI publishes industry-average rates. The 2024 spot-market average ran around $2.40–$2.80/mile for OTR Class 8 dry van. Reefer and flatbed run higher because of equipment cost and operational complexity. Hot-shot and expedited freight run materially higher per mile but on shorter, less consistent runs. RPM is not the same as line-haul rate — accessorials (detention, layover, tarp pay, lumper, etc.) and fuel surcharge add to RPM, and a load with strong line-haul but weak accessorial collection can realize lower RPM than the rate confirmation suggested.
Some operators quote RPM by loaded mile only, ignoring deadhead. That practice inflates the number and creates a false sense of profitability. The honest calculation uses total miles in the denominator.
Why it matters for trucking finance
RPM by itself is meaningless without knowing CPM. A $2.50/mile RPM on a $2.30 CPM operation is barely viable — 8% gross margin before any unexpected event eats it. The headline RPM quoted to a driver looking at a load doesn't include deadhead repositioning, fuel-surcharge volatility on long-distance lanes, or accessorial collection rate, which means the realized RPM is often 10–20% lower than the rate confirmation.
Understanding the RPM-CPM gap is the difference between profitability and slow insolvency. Lenders sometimes look at RPM trends as a signal of carrier pricing power and broker-mix quality — a carrier whose realized RPM is rising in a flat market is winning on customer selection, not just lane luck.
