How to Calculate Deadhead Miles and Reduce Empty Truck Miles
Deadhead miles are one of the hidden costs of running a trucking business. Every mile a truck travels without a paying load can increase fuel expenses, add wear and tear to the equipment, and reduce overall profitability.
For owner-operators, fleet managers, and freight dispatchers, understanding deadhead miles is essential when comparing loads, planning routes, and deciding whether a freight offer makes financial sense.
In this guide, you will learn how to calculate deadhead miles, estimate their cost, and use practical strategies to reduce unnecessary empty driving.
What Are Deadhead Miles in Trucking?
Deadhead miles are miles driven by a commercial truck without freight in the trailer. They commonly occur when a driver travels to a pickup location, moves between loads, or returns from a delivery without securing another shipment.
For example, a truck delivers a load in Dallas, Texas, but the next pickup is in Fort Worth. If the driver travels to the next pickup without freight, those miles are considered deadhead miles.
Deadhead miles are not always avoidable. Sometimes a truck must reposition to reach a better market or prepare for a scheduled pickup. The goal is to manage these miles strategically rather than eliminate every empty mile at any cost.
How to Calculate Deadhead Miles
Calculating deadhead miles starts with identifying the distance your truck travels without a paying load.
Use this basic formula:
Deadhead Miles = Total Miles Driven Without Freight
For example, imagine a truck completes a delivery and travels 75 miles to reach its next pickup location.
The truck has accumulated 75 deadhead miles.
If it then travels another 425 miles carrying freight, the trip includes:
- Deadhead miles: 75
- Loaded miles: 425
- Total miles: 500
To calculate the deadhead percentage, use this formula:
Deadhead Percentage = Deadhead Miles ÷ Total Miles × 100
In this example:
75 ÷ 500 × 100 = 15%
The truck traveled empty for 15% of its total miles during this example trip.
Tracking this percentage over time helps carriers understand how efficiently they are positioning their trucks between loads.
How Much Do Deadhead Miles Cost?
Even without freight in the trailer, your truck continues to consume fuel and accumulate operating expenses.
To estimate the cost of deadhead miles, multiply the empty miles by your operating cost per mile.
Deadhead Cost = Deadhead Miles × Operating Cost Per Mile
Consider this example:
- Deadhead distance: 100 miles
- Operating cost: $1.00 per mile
- Estimated deadhead operating cost: $100
The $1.00 operating cost in this example is illustrative. Your actual cost may be higher or lower depending on fuel prices, maintenance, insurance, equipment payments, and other expenses.
Remember that this calculation estimates the operating cost of the empty trip. If your overall cost-per-mile calculation already includes those miles, do not add the same expenses twice.
For a more complete financial picture, consider whether the empty trip also creates toll expenses, additional waiting time, or lost opportunities to accept another load.
How Deadhead Miles Affect Your Rate Per Mile
One of the biggest mistakes in freight planning is evaluating a load using only its loaded miles.
Suppose a broker offers $1,500 for a shipment covering 600 loaded miles. You also need to drive 100 empty miles to reach the pickup.
Your total trip distance is 700 miles.
Rate Per Loaded Mile
$1,500 ÷ 600 = $2.50 per loaded mile.
Revenue Per Total Mile
$1,500 ÷ 700 = approximately $2.14 per total mile.
The advertised rate looks stronger when you consider only loaded miles. However, the total-mile calculation provides a more complete picture of the revenue generated across the distance driven for that load.
Revenue per total mile is not the same as profit per mile. To estimate profit, you must also subtract the relevant operating expenses.
Five Ways to Reduce Deadhead Miles
1. Search for Loads Near Your Delivery Location
Before accepting a load, consider where it will leave your truck after delivery.
A shipment that pays well may take you to a location with limited freight opportunities. Another load with a slightly lower rate may position your truck closer to a stronger outbound market.
Evaluate both the current shipment and your likely next move.
2. Plan Your Next Load Before Delivery
Whenever possible, begin looking for the next load before completing your current delivery.
Early planning gives you more time to compare pickup locations, delivery schedules, and available freight options. It can also reduce unnecessary repositioning while you wait for your next assignment.
Keep appointment times and your driver’s available hours in mind when planning the next trip.
3. Compare Total Trip Distance
Do not compare freight offers using the advertised rate alone.
For each option, consider:
- Miles from your current location to pickup
- Loaded miles to delivery
- Estimated fuel and toll costs
- Pickup and delivery appointment requirements
- Expected waiting time
- Available reload opportunities near the destination
A slightly lower-paying load may be more attractive if it requires less deadhead driving and positions the truck for another suitable shipment.
4. Understand Your Freight Markets
Some locations offer more outbound freight opportunities than others. Seasonality, industry demand, weather, and regional shipping patterns can influence load availability.
Use current load-board information and your own historical experience to understand which destinations tend to work best for your operation.
Avoid relying on assumptions alone. A market that performs well one week may have different conditions the next.
5. Track Your Deadhead Percentage
Review deadhead miles regularly to identify patterns in your operations.
For example, if a particular route consistently produces long empty trips, compare alternative delivery markets or review your reload planning.
A simple weekly report can include total miles, loaded miles, deadhead miles, total revenue, and estimated operating costs.
These figures can help you identify where changes may improve efficiency.
How Dispatchers Can Help Reduce Empty Miles
Dispatchers play an important role in managing deadhead miles. Effective load planning requires balancing rate, distance, appointment times, driver availability, and the location of the next potential shipment.
Before booking a load, a dispatcher should consider how the shipment fits into the truck’s overall schedule.
A useful evaluation process includes checking the pickup distance, estimating the total trip mileage, comparing the offered rate, and reviewing possible reload options.
Communication between the dispatcher and driver is also essential. Current location, delivery progress, hours of service, and equipment availability all influence which loads are realistic options.
The objective is not simply to find the highest-paying load. It is to help the truck complete suitable, profitable trips while minimizing unnecessary mileage and downtime.

Common Deadhead Mileage Mistakes
Ignoring empty miles when evaluating a load. Always consider the distance required to reach pickup and any other empty travel associated with the trip.
Chasing the highest rate without checking the destination. A strong rate may not be as attractive if the delivery location creates a long empty repositioning trip.
Forgetting fuel and operating expenses. Empty miles still consume fuel and contribute to equipment wear.
Waiting until delivery to search for the next load. Planning ahead may provide more options and reduce avoidable downtime.
Tracking miles inconsistently. Use the same definitions for loaded miles, deadhead miles, and total miles when comparing performance over time.
Frequently Asked Questions
What is considered a deadhead mile?
A deadhead mile is a mile driven by a truck without freight in the trailer. This often happens when traveling to a pickup location or repositioning after a delivery.
How do you calculate deadhead percentage?
Divide deadhead miles by total miles driven and multiply the result by 100. For example, 100 deadhead miles out of 800 total miles equals a 12.5% deadhead rate.
Are deadhead miles always bad?
No. Some empty driving is necessary to reach a suitable pickup or reposition a truck to a stronger freight market. The goal is to understand the cost and make sure the overall trip makes business sense.
How can owner-operators reduce deadhead miles?
Owner-operators can plan reloads earlier, compare pickup distances, review destination markets, track empty-mile percentages, and evaluate the full trip rather than focusing only on the advertised rate.
Should deadhead miles be included in cost per mile?
Yes. For an accurate overall operating cost per mile, include all miles driven, both loaded and empty, while keeping the expenses and mileage period consistent.
Final Thoughts
Deadhead miles are an important part of trucking profitability. Although some empty driving is unavoidable, understanding where and why it happens can help you make better decisions about load selection and route planning.
Track your loaded miles, deadhead miles, operating costs, and revenue regularly. Use those figures to compare freight opportunities based on the entire trip rather than the advertised rate alone.
With better planning and consistent tracking, owner-operators and dispatchers can identify opportunities to reduce unnecessary mileage and improve operational efficiency.
