How this calculator works
Deadhead is any mile you drive without freight — repositioning to a pickup, running back toward home, or moving to a market where there is work. The miles cost you fuel, tyres, maintenance and hours, and they earn nothing directly.
This calculator gives you the percentage, and if you add revenue it shows what those empty miles do to your rate per mile.
total miles = loaded + deadhead deadhead % = deadhead ÷ total × 100 revenue per total mile = revenue ÷ total miles
Worked example
| Figure | Value |
|---|---|
| Loaded miles | 900 |
| Deadhead miles | 120 |
| Total miles | 1,020 |
| Deadhead share | 11.8% |
| Revenue | $2,500 |
| Per loaded mile | $2.78 |
| Per total mile | $2.45 |
Just under twelve percent empty running costs 33 cents on every mile. The percentage sounds small; the per-mile effect is not.
Deadhead costs more than the percentage suggests
It is tempting to treat empty miles as merely unpaid. They are worse than that, because they consume things you have a finite supply of:
Fuel
An empty trailer burns less than a loaded one, but not much less. The fuel cost of deadhead is close to the fuel cost of paid running.
Driving hours
Empty miles count against your 11-hour driving limit exactly like loaded miles. Two hours of deadhead is two hours you cannot drive freight.
The 14-hour window
Repositioning eats window that a paying load could have used.
Maintenance
Tyres, brakes and the engine do not know whether the trailer is loaded. Wear accrues per mile.
Opportunity
Every hour spent repositioning is an hour not available for a load that pays.
Cycle hours
Deadhead is on-duty driving time, so it consumes your 60 or 70 hour cycle at the same rate as anything else.
Track it across a month, not a load
One bad trip is not a pattern. A single 400-mile repositioning move to reach a strong market can be a good decision even though it looks terrible in isolation.
What matters is the trend. Track deadhead across a month and you can see whether your lane choices, your load sourcing or your home base are structurally costing you empty miles — which is a question you can actually act on.
Why there is no target percentage here
A reasonable deadhead figure depends on your equipment, your lanes, how you source freight and where you are based. A flatbed operator running regional and a reefer operator running long-haul have genuinely different baselines.
This calculator gives you your number rather than a benchmark. Compare it against your own history — that is the comparison that means something.
Frequently asked questions
What are deadhead miles?
Miles driven with an empty trailer — usually repositioning to reach the next load, or returning toward base. They cost fuel, maintenance and driving hours, and earn nothing directly.
What is a normal deadhead percentage?
It varies widely by equipment, lane, how you source freight and where you are based. Track your own figure over time rather than aiming at a general benchmark, because the benchmark for a regional flatbed operator and a long-haul reefer operator are genuinely different.
Do empty miles count against my hours of service?
Yes. Driving is driving whether the trailer is loaded or not. Deadhead consumes your 11-hour driving limit, your 14-hour window and your weekly cycle at exactly the same rate.
Should I include the drive home in my deadhead figure?
If you want the full picture of unpaid running, yes. Whichever you choose, stay consistent so the figures remain comparable month to month.
Is a long deadhead ever worth it?
Sometimes. A 400-mile repositioning move to reach a strong market can be a good decision even though it looks terrible in isolation. That is exactly why the monthly trend matters more than any single trip.
Does an empty trailer save much fuel?
Less than most people expect. An empty trailer burns somewhat less than a loaded one, but the difference is nowhere near enough to make deadhead miles cheap.
How do I reduce deadhead?
Usually through load sourcing and lane selection rather than driving decisions. Backhauls, lane pairing and choosing a base near freight density all move the number more than anything you can do on the road.
Why does the calculator not show a target?
Because a target that ignores your equipment, lanes and freight sources would be misleading. Compare against your own history — that comparison actually means something.
