Operating ratio (OR) is the metric the larger trucking industry uses to compare carriers, and it gets thrown around in podcasts and forums as if it had universal meaning. The reality is that OR for a single-truck owner-operator is calculated very differently from OR at a 500-truck carrier, and the "good" OR number depends entirely on which version of the calculation you're using. Knowing what's actually included in your OR — and what isn't — matters more than the headline number, because misreading the calculation produces over-optimistic financial conclusions about your own operation.

The basic formula

Operating Ratio = (Operating Expenses ÷ Operating Revenue) × 100

If a carrier has $250,000 of operating revenue and $200,000 of operating expenses:

OR = ($200,000 ÷ $250,000) × 100 = 80

An OR of 80 means 80% of revenue is consumed by operations, leaving 20% as operating margin. Lower OR is better — more revenue retained as margin.

What "operating expenses" usually includes for a small carrier

For a single-truck owner-operator, operating expenses typically include:

  • Fuel. The largest single line item.
  • Insurance. All lines (primary liability, cargo, physical damage, GL).
  • Maintenance and repairs. Including tires, oil changes, scheduled service.
  • Driver pay. For owner-operators driving themselves, this is owner compensation. For carriers with employed drivers, it's payroll.
  • Equipment costs. Either lease/finance payments, or depreciation if owned outright. The treatment varies.
  • Tolls, scales, permits. Operational fees.
  • Trailer and tractor licensing. IRP, registration, etc.
  • Compliance. Drug consortium, DOT-related fees, IFTA processing.
  • Administrative. Phone, internet, dispatch tools, accounting, factoring fees.
  • Truck washes, parking.

What's typically not in operating expenses:

  • Interest expense on financing. Usually shown as a separate line below the OR calculation.
  • Income taxes. Calculated on net income after OR.
  • Owner's personal living expenses. These come out of net income.

What "operating revenue" includes

Operating revenue is what you bill for transportation services:

  • Linehaul payments
  • Fuel surcharges
  • Accessorials (detention, lumper reimbursements, layover, etc.)

What's not in operating revenue:

  • Interest income on cash balances
  • Gain on sale of equipment
  • Insurance recoveries (other than as offsets to expense)
  • Investment income

For most small carriers, the distinction is academic — operating revenue is essentially all the money coming in from freight.

The OR variation that matters: owner compensation

This is where small carrier OR comparisons get distorted.

A large carrier with employed drivers includes driver wages as a fixed operating expense. Their OR reflects the cost of paying drivers.

A single-truck owner-operator doing all the driving themselves has a choice in how they calculate OR:

Method 1: Include owner-driver compensation as an expense. Treat your effective "wage" as if you were paying yourself. A reasonable proxy is what you'd have to pay a hired driver — say $50,000 to $70,000 annually for a solo OTR driver in 2026. Including this gives an apples-to-apples comparison with multi-truck carrier OR.

Method 2: Exclude owner-driver compensation. Treat your entire net income (after all other expenses) as your effective compensation. This makes the OR look dramatically lower because driver pay isn't an expense.

The same operation can have a 65 OR under Method 1 and a 45 OR under Method 2. Both are "correct" calculations; they're answering different questions.

When you see industry benchmarks ("good OR for OTR is below 90," "elite OR is below 80"), these benchmarks are based on Method 1 calculations from multi-truck carriers. An owner-operator using Method 2 and comparing themselves to those benchmarks is comparing apples to oranges.

A realistic worked example

A solo OTR owner-operator in their first year:

  • Revenue: $250,000 (gross)
  • Fuel: $65,000
  • Insurance: $14,000
  • Maintenance and tires: $18,000
  • Owner-driver compensation (proxy): $50,000
  • Equipment depreciation: $20,000
  • Admin, tools, permits, factoring fees: $15,000
  • Total operating expenses: $182,000

OR (Method 1) = $182,000 ÷ $250,000 = 72.8

That's a respectable OR for a year-one solo. The 27.2% margin includes the owner-driver compensation as an expense; the actual net income to the owner is roughly $50,000 (the proxy compensation) plus $68,000 (the operating margin) = $118,000 before income taxes.

If you exclude the owner-driver compensation (Method 2):

OR (Method 2) = $132,000 ÷ $250,000 = 52.8

A 52.8 OR sounds amazing — but it's not the same metric as the 80 OR you might see from a publicly-traded LTL carrier. Same operation, different methodology.

What OR doesn't tell you

OR is a margin metric, but it doesn't tell you about:

  • Cash position. A carrier can have a great OR and still be cash-poor due to AR timing.
  • Asset turnover. Two carriers with identical OR can have very different revenue-per-truck.
  • Debt-service coverage. OR doesn't reflect whether you can make your loan payments.
  • Equipment age and refresh requirements. A carrier deferring maintenance has artificially good OR that will catch up to them.
  • Sustainability. OR captures one year; it doesn't show whether you're building or depleting the business.

A focused OR review is one input to financial health, not the whole picture.

OR benchmarks for small carriers

Reasonable OR benchmarks for owner-operators using Method 1 (with owner-driver compensation included):

  • Below 70: Excellent. Strong operation, good cost control, healthy margin.
  • 70-80: Good. Standard for well-run small carrier.
  • 80-90: Acceptable. Adequate but with room for improvement.
  • 90-95: Marginal. Operating but not building meaningful reserves.
  • Above 95: Unsustainable. Something needs to change.

These are rough — every operation has variations — but they give a sense of where a year-one carrier should be aiming.

What drives OR improvement

The line items that most often improve over time:

  • Fuel. Better fuel-buying patterns, better card discounts, more efficient routing reduce fuel cost per mile.
  • Insurance. Year 2+ premium reductions of 10-20% after clean year one.
  • Maintenance. Established maintenance program with consistent shop relationships reduces emergency repair costs.
  • Empty miles. Better lane development — which is a dispatch outcome, not a load-board exercise — reduces deadhead and lifts revenue per total mile.
  • Rate. Stronger lane and broker relationships, maintained by your dispatch team, improve rate per loaded mile.
  • Equipment efficiency. Newer or better-maintained equipment improves MPG and reduces breakdown frequency.

The OR improvements from year one to year three for a well-run small carrier are typically 5-10 OR points — meaningful but incremental, achieved through dozens of small improvements rather than dramatic single moves.

Honest caveat: OR is not the only metric that matters

Carriers who optimize purely for OR sometimes make decisions that look right on the metric but wrong for the business. Skipping maintenance to lower expense, refusing freight to control deadhead at the expense of cash flow, deferring equipment refresh — these moves can improve OR in one period while damaging the business over multiple periods. The honest read is that OR is a useful summary metric that should be read alongside cash flow, equipment condition, broker relationship health, and CSA scores. A carrier with great OR but a damaged broker book and aging equipment is in worse shape than a carrier with mediocre OR and strong relationships and current equipment. Treat OR as one indicator in a dashboard, not as the goal in itself.

The OR conversation in the small carrier world often suffers from imprecise methodology and inappropriate benchmarks. Calculating yours consistently, comparing to relevant benchmarks, and tracking the trend over time produces useful information. Chasing a low number for its own sake produces the wrong incentives.

If you want a dispatch team that helps you compound those small annual improvements — better lanes, stronger broker book, fewer empty miles — talk to dispatch.
