A truck does not stop costing money just because the trailer is empty.
When an owner-operator drives 75 miles to reach a pickup, those 75 miles still use fuel, tires, maintenance capacity, driver time and equipment life even though the carrier has not yet started earning revenue from the load.
Those empty miles are commonly called deadhead, and they can have a major effect on the real economics of freight.
What Are Deadhead Miles in Trucking?
Deadhead miles are miles a commercial truck travels without a paying load.
One common example is the distance between your current location and the pickup location for the next load.
Deadhead can also happen after delivery when a truck must travel empty to another freight market, terminal, parking location or home base.
The fact that a truck is empty does not mean the miles are free. They still form part of the movement required to keep the operation running.
Why Deadhead Miles Matter
A freight load is often advertised using the mileage from pickup to delivery. That gives you the loaded mileage, but it does not necessarily show all of the miles required to run the load.
Suppose the load itself covers 700 miles, but you need to drive 150 miles empty to reach the shipper.
From the truck's perspective, the movement requires 850 miles, not 700.
That difference can affect your effective revenue per mile, estimated operating cost, fuel consumption and the amount of time required to complete the overall movement.
How to Calculate Deadhead Percentage
One way to understand how much of a trip is empty is to calculate the percentage of total miles that are deadhead.
Using the 150-mile deadhead and 700-mile loaded example:
That means almost one-fifth of the total movement is being driven without revenue-producing freight.
There is no universal deadhead percentage that automatically makes a load good or bad. What matters is whether the complete load still works for your business after all the miles and costs are considered.
How Deadhead Changes Your Real Rate Per Mile
Deadhead is especially important when comparing loaded RPM with effective RPM.
Loaded RPM
Effective RPM
The load revenue does not increase simply because you had to drive farther to reach the pickup.
As deadhead increases, the same revenue is spread across more miles, which generally reduces effective revenue per mile.
FREE TOOLDeadhead Example: Same Load, Different Result
Consider a load paying $2,400 for 700 loaded miles.
Now compare two trucks in different positions.
Truck A effective RPM
Truck B effective RPM
Both trucks are offered exactly the same freight at exactly the same loaded rate.
But because Truck B is much farther from the pickup, its effective revenue per mile is substantially lower.
A load does not have the same economics for every truck. Your current position matters.
What Do Deadhead Miles Really Cost?
The easiest way to estimate the direct operating impact is to use your own cost per mile.
Suppose your estimated operating cost is $1.70 per mile and you have 150 deadhead miles.
In this simplified example, reaching the pickup could represent approximately $255 of operating cost before the loaded portion of the trip is even considered.
That is one reason why the closest load is not always the best load, but distance to pickup should always be part of the evaluation.
Deadhead affects more than fuel
Fuel is the most visible cost, but empty miles can also contribute to:
Ways Owner-Operators Can Reduce Deadhead
It is unlikely that a trucking business can eliminate every empty mile. The more realistic goal is to recognize deadhead and manage it deliberately.
Know your current position
When comparing loads, calculate the actual distance from your truck to each pickup rather than looking only at loaded mileage.
Compare effective RPM
Include deadhead when comparing two freight opportunities. A higher loaded RPM may not remain higher after total mileage is considered.
Think about the destination
A load that delivers into an area with stronger outbound freight may reduce the deadhead required for your next load.
Plan lanes instead of isolated loads
Sometimes the value of a load becomes clearer when you consider how it fits into the next move rather than evaluating only one trip at a time.
Track empty mileage over time
Looking at your historical deadhead can help you identify lanes or patterns that repeatedly create excessive empty miles.
Can a Load With More Deadhead Still Make Sense?
Yes. Deadhead is a cost factor, not an automatic reason to reject a load.
A carrier might deliberately accept additional empty mileage if the freight pays enough to justify it or if the movement positions the truck for something strategically useful.
For example, deadhead may be more acceptable when:
The load moves your truck toward home, into a preferred freight lane, away from a weak market, or into an area where the next load is expected to be stronger.
The important point is to know the empty miles are there and include them in your decision rather than discovering their impact after the trip.
Frequently Asked Questions
What are deadhead miles in trucking?
Deadhead miles are miles a truck travels without carrying revenue-producing freight. This often includes driving empty to a pickup or repositioning after a delivery.
Do deadhead miles cost money?
Yes. Empty miles can still use fuel, tires, maintenance, driver time and equipment life even though they do not directly generate freight revenue.
Should I include deadhead when calculating RPM?
Including deadhead gives you an effective RPM that spreads the load revenue across all miles required to reach the pickup and complete delivery.
Is all deadhead bad?
No. Some empty mileage may make strategic sense if the overall load economics work or if the move positions the truck for home, a preferred lane or better future freight.
How can I calculate the cost of deadhead?
A simple planning method is to multiply your deadhead miles by your estimated operating cost per mile. Actual costs can vary by operation.
