A new carrier sees a load posted at a strong per-loaded-mile rate and thinks they've found a winner. Then they remember the truck is sitting 175 miles away from the pickup. The honest rate isn't the headline number — it's the total revenue divided by the total miles the truck moved, loaded and empty, and that math turns the headline rate into something noticeably lower. The same load looks great on the post and merely okay in real economics. Carriers who think about every load in terms of loaded-only revenue end the year wondering where the money went. Carriers who run the deadhead math on every booking end the year knowing.
What "deadhead" actually counts
Deadhead miles are any miles the truck runs without a paying load on the trailer. The usual scenarios:
- Pickup deadhead: miles from the truck's current location to the next pickup.
- Delivery deadhead: miles after delivery to the next pickup.
- Repositioning: miles run to get from a soft market to a stronger one without a load.
Bobtail miles — driving without the trailer entirely — also count as non-revenue miles, though they're typically a smaller share of total.
What doesn't count as deadhead, technically:
- Trailer drops where payment is owed for the drop even though the trailer is empty (empty trailer relocation under contract is usually paid).
- Mileage during fuel stops, lunch, and similar — those are part of the loaded leg.
Deadhead percentage industry-wide for OTR carriers typically runs in the mid-teens to low-twenties. New carriers without optimized lanes often run higher in the first six months. Mature carriers with strong lane positions can run in the single digits.
The two ways carriers do the math wrong
The first wrong way is calculating revenue per loaded mile and ignoring deadhead entirely. A carrier hauls a load at a strong loaded-mile rate after deadheading 200 miles to the pickup. They say "I ran a great per-mile load." They didn't — at least not on the truck's actual movement. They moved the truck 800 miles for whatever the headline payment was, and the per-total-mile number is meaningfully lower than the per-loaded-mile number. Treating the headline as the real number distorts every decision downstream.
The second wrong way is treating all deadhead as equally bad. A short deadhead to a strong outbound market that gets the truck re-loaded in two hours is fundamentally different from a long deadhead into a soft market where the truck sits overnight before getting a next load. Total miles tells you what the truck cost. The quality of the deadhead — what comes next — tells you whether the route plan was good.
The right math is total revenue divided by total miles, evaluated across the round trip or the week, not the single load.
Worked examples
A few simple cases that illustrate the principle:
Example 1. A $1,800 load for 600 loaded miles, no deadhead at all (the next load originates where this one delivered). Revenue divided by total miles: $1,800 ÷ 600 = $3.00 per total mile. This is the headline rate.
Example 2. Same $1,800 / 600-mile load, but with 100 miles of pickup deadhead. Revenue divided by total miles: $1,800 ÷ 700 = $2.57 per total mile. The "true" rate is about 14% lower than the posted rate.
Example 3. Same $1,800 / 600-mile load, but with 200 miles of pickup deadhead. Revenue divided by total miles: $1,800 ÷ 800 = $2.25 per total mile. Now it's a 25% reduction from the headline.
Comparing two options head-to-head:
- Load A: $2,400 for 600 loaded miles, 50 deadhead = $2,400 ÷ 650 = about $3.69 per total mile.
- Load B: $2,800 for 600 loaded miles, 250 deadhead = $2,800 ÷ 850 = about $3.29 per total mile.
Load B pays $400 more on the headline rate but produces roughly $0.40 per mile less in real economics, because the deadhead is eating most of the difference. Carriers who book on posted rate alone choose B. Carriers (or the dispatch desks supporting them) who book on total-mile economics often choose A.
When deadhead is worth it anyway
Pure mile math isn't the only consideration. There are real cases where a longer deadhead is the right move:
- Getting to a strong outbound market. Eating 200 miles of deadhead to get out of a soft market into a strong one, with the next load already lined up at a higher rate, can be net positive.
- Positioning for a high-paying lane. If a regular shipper consistently posts strong loads on a known day out of a specific terminal, deadheading there to be first available can be the right move.
- Avoiding a worse alternative. Sometimes the choice is deadhead to a known opportunity versus sit somewhere with no posted loads and an uncertain next move. Movement to known revenue beats waiting on unknown revenue when the cost-per-mile is roughly equal idle versus running.
The disciplined version of this calculation: deadhead is worthwhile if the next loaded leg's rate, less the cost of the deadhead miles, is higher than what would have been earned by waiting where the truck was.
A simplified way to think about it: every deadhead mile costs the carrier real direct cost (fuel, maintenance allocation, driver pay if applicable) plus an opportunity cost depending on the market. So 100 deadhead miles has a real cost the next load has to clear before the move makes sense. The "free deadhead" only feels free.
The "deadhead reimbursement" conversation
Some brokers will pay a deadhead allowance if the truck has to reposition significantly to pick up. The conversation usually goes like this: the carrier (or the dispatch desk) notes the deadhead distance and asks whether the load has a deadhead allowance. The broker either offers an additional flat amount for the deadhead or doesn't.
Whether they offer depends on the market. In a tight market where they've been struggling to cover, they often will. In a loose market with many trucks available, they typically won't — they'll call the next truck on the list that's closer.
Asking the question doesn't cost anything and occasionally produces real money. The pattern of when brokers will and won't is something a dispatch desk learns across many corridors and applies on behalf of the carriers it covers.
Tracking your own deadhead percentage
The number worth knowing about an operation, monthly:
Deadhead % = (Total empty miles ÷ Total all miles) × 100
For a week of running with 2,800 total miles and 450 of those empty: deadhead percentage = 450 ÷ 2,800 = 16%.
How to compare:
- High-20s: typical of new carriers without lane discipline.
- Mid-teens to low-20s: average mature OTR.
- Single digits to low-teens: well-run dedicated lanes and strong broker relationships.
If deadhead is consistently above the high-20s, it's almost always a lane choice problem rather than an unsolvable structural issue. The fix is usually a combination of:
- Focusing on a smaller set of corridors where a reload pattern can develop.
- Choosing destinations where outbound freight is reliable.
- Refusing loads into known dead markets unless the rate covers the deadhead.
A deadhead percentage that drops over six months is the operational signature of a carrier figuring out their freight.
Honest caveat: deadhead is partly outside your control
A new carrier without contract freight and without a broker book is going to run more deadhead than a carrier with three years of relationships and dedicated lanes. That's not a failure of planning — it's the cost of being new. Treating the first six months as a learning period during which deadhead is structurally higher, and tracking the trend rather than the absolute number, is more honest than benchmarking against mature carriers. A new carrier whose deadhead drops a percentage point or two per month over the first six months is improving on the right curve. A new carrier whose deadhead stays flat is operating on whatever loads happen to come up rather than building a pattern. The pattern is the goal, and the pattern shows up in the deadhead trend before it shows up anywhere else.
The cleanest way to think about deadhead is as a tax on every load that pays nothing per mile and costs everything per mile. The carriers who get good at minimizing it aren't the ones running every load that pays the highest per-loaded-mile number; they're the ones running the loads that pay reasonably and leave the truck somewhere with a next load already attached.
Talk to dispatch
Lowering deadhead isn't really about negotiating harder on individual loads — it's about being on a freight pattern where the next load is already in view when the current one finishes. That's the work a dispatch desk does. Talk to dispatch about building a freight pattern that keeps the truck loaded.
