Operating ratio (OR) excludes interest and taxes and asks only whether the core activity of moving freight makes money. Revenue is transportation billing plus accessorials; expenses are driver pay, fuel, maintenance, insurance, dispatch, tolls, and overhead.
An OR of 100% is operating breakeven. Every point below is operating profit as a share of revenue — a carrier at 94% keeps six cents of every revenue dollar before debt and taxes. Consistently above 100% means the operation loses money on freight itself.
Small carriers can run a lower OR than large ones when rates are strong because overhead is lean, but they also swing harder when rates fall, since more of their revenue is spot.
Example
A carrier bills $600,000 in a quarter and spends $558,000 to produce it. OR is 93% — $42,000 of operating profit before financing and taxes. If the next quarter’s OR jumps to 99%, the same revenue would yield only $6,000, a signal to look hard at either rates or costs.
Why it matters
OR is the single number that says whether the trucking is working. It separates a rate-cycle dip from a structural cost problem.
