How do you calculate a carrier operating ratio?
Operating ratio equals total operating expense divided by total revenue, times 100. Revenue needed for a target OR equals total expense divided by the target OR as a decimal, and the cost cut needed instead equals total expense minus revenue times the target OR as a decimal.
Founded in 2008 by Scott Elliott in Minnesota, Strong Tower Consulting, LLC (Minnesota File No. 2948628-2) has advised carriers for more than 18 years on the accounting integration, SQL data mining, and business process optimization work that turns a monthly OR into a number dispatch and billing can act on.

Show the math
- Total operating expense = fuel + driver and labor + equipment + insurance and claims + maintenance and tires + overhead and admin
- Operating ratio = total operating expense / total revenue x 100
- Operating income = total revenue - total operating expense
- Bucket OR contribution = bucket dollars / total revenue x 100
- Bucket share of expense = bucket dollars / total operating expense x 100
- Revenue needed for target OR = total operating expense / (target OR / 100)
- Revenue gap = revenue needed - current revenue
- Cost cut needed instead = total operating expense - current revenue x (target OR / 100)
What operating ratio means in plain terms
Operating ratio answers one question: of every dollar of revenue, how many cents did it take to run the trucks? An OR of 95 means 95 cents went out the door for fuel, drivers, equipment, insurance, maintenance, and overhead, and 5 cents were left as operating income before interest on debt and before income tax. An OR of 100 is breakeven on operations. Anything above 100 is an operating loss.
The ratio is popular in trucking because it strips out fleet size. A 20 truck carrier and a 2,000 truck carrier can both read their OR the same way. It is also the figure that publicly traded carriers report in their SEC filings, which makes those 10-K and quarterly reports a useful reference point when you want to see how carriers with a similar freight mix are performing. This page does not state a benchmark OR as fact. Look up the filings for carriers that resemble yours and compare periods on the same basis.
How the model works
- Add the six buckets. Fuel, driver and labor, equipment, insurance and claims, maintenance and tires, and overhead and admin sum to total operating expense.
- Divide by revenue. Total expense over total revenue, times 100, is your OR. Revenue minus expense is operating income.
- Break the OR into points. Each bucket divided by revenue gives that bucket's contribution in OR points. The points add up to the total OR, so you can see which line is carrying the most weight.
- Show each bucket as a share of expense. Dividing by total expense instead of revenue tells you how the cost structure is shaped, independent of pricing.
- Price the target. Dividing total expense by the target OR as a decimal gives the revenue you would need at the same cost. Subtracting current revenue gives the gap.
- Or cut cost instead. Revenue times the target OR as a decimal is the expense you could afford at that target. Total expense minus that figure is the cut you would need.
Reading the bucket table
The bucket table is where the ratio becomes a decision. If driver and labor are the largest OR contributor, the levers are utilization, deadhead, and pay model, and the data to study lives in dispatch and settlements. If fuel is the largest, the levers are surcharge recovery, routing, and idle time, and the data lives in fuel cards and ELD feeds that an ELD and EDI integration can bring into the TMS. If equipment is the largest, the conversation is about trailer pool size, tractor age, and financing terms.
Carriers that cannot produce these six buckets cleanly for a single period usually have a chart of accounts or a TMS to accounting handoff that needs work. That is a business process optimization project before it is a cost cutting project. Buyers running carrier acquisition due diligence also use this breakdown to normalize a target's OR before comparing it to their own.
Fuel surcharge and the two ways to compute OR
The most common reason two people get different ORs for the same carrier is fuel surcharge. One method puts surcharge in revenue and the full fuel bill in expense. The other nets surcharge against fuel and reports OR on freight revenue only. Both are defensible. Mixing them is not. Decide which one you use, note it on your report, and use the same method when you compare months, compare against public filings, or set the target OR in this calculator.

Frequently asked questions
What is a trucking operating ratio?
Operating ratio, or OR, is total operating expense divided by total revenue, shown as a percent. An OR of 95 means 95 cents of every revenue dollar went to operating costs and 5 cents remained as operating income before interest and taxes. Lower is better. An OR at or above 100 means the carrier lost money on operations.
What is a good operating ratio for a carrier?
There is no single correct figure, and this calculator does not state one. Publicly traded carriers report operating ratio in their SEC filings, so their 10-K and quarterly reports are a reference point you can check for carriers of a similar size and freight mix. Private fleets vary widely with equipment age, driver pay model, and how fuel surcharge is booked. The target OR input is yours to set.
Should fuel surcharge revenue be included in total revenue?
Be consistent. If you include fuel surcharge in revenue, include the full fuel cost in the fuel bucket. Some carriers net surcharge against fuel expense and report OR on freight revenue only, which produces a different number from the same operation. Pick one method, label it, and use the same method when you compare periods or compare against public filings.
How do I use the revenue needed and cost cut needed outputs?
They are two paths to the same target OR. Revenue needed holds your cost structure fixed and shows how much more revenue you would need at the same cost. Cost cut needed holds revenue fixed and shows how much expense you would need to remove. In practice most carriers do some of both, so use the bucket table to see which cost lines carry the most weight before deciding where to start.
