The True Cost of Driving Empty: Deadhead Miles Math
Deadhead miles bleed cash. Learn how to compute your real cost per deadhead mile, run a worked example, and use per-load math to say yes or no to a load before you move.
You pull out of a pickup and the dispatcher offers you a load two hours away at a rate that sounds OK — but you won't have a load back. Do the math before you accept. That deadhead home will cost you more than fuel.
Deadhead's sneaky. Everyone talks about mpg and fuel surcharges, but you pay for wear, insurance exposure, lost paying miles, and time. If you don't add those up and price deadhead into the trip, you're working for free on parts of the run.
The pieces of deadhead cost
Here are the things you should count for every empty mile:
- Fuel burn: actual gallons times your price per gallon. Use your real mpg, not what the truck sticker says.
- Time cost (your pay target): value of your time per hour divided by your loaded miles per hour, or convert to a per-mile number if you prefer.
- Maintenance and tires: add a per-mile allowance for wear and tear. This includes tires, oil, brakes — everything that wears whether you're empty or loaded.
- Depreciation: every mile reduces the truck's resale value. Put a per-mile number on that too.
- Insurance and permit exposure: not huge per mile, but it exists. Include a small per-mile charge for insurance cost.
- Opportunity cost: the paying miles you could've run instead. This matters most to owner-ops — if a deadhead blocks a paid run you lose revenue.
- Other fees: tolls, scales, lumper if you handle freight, and possible detention if you end up waiting.
Pick numbers that reflect your rig and lifestyle. Don't guess to sound hopeful.
Quick way to build a deadhead-per-mile number
- Fuel per mile = (1 / mpg) * price per gallon.
- Maintenance per mile = your monthly maintenance budget divided by monthly miles, or industry-typical breakdown for your truck age.
- Depreciation per mile = (expected resale loss over owning period) / total expected miles.
- Insurance per mile = annual insurance / annual miles.
- Time cost per mile = (what you want to earn per hour) / average loaded mph. If you prefer per-mile pay target, use that.
- Add tolls or other fixed costs for that specific deadhead.
Add them all. That's your true cost of deadhead miles.
Worked example (all numbers hypothetical — plug in your own)
You're running a 53-foot dry van. Your real numbers:
- Truck gets 7.0 mpg average.
- You pay $5.31/gal for diesel at the pump today (the EIA's weekly number for the week of 2026-07-27 is $5.313/gal). Use what you pay locally if different.
- Maintenance & tires: you budget $0.12/mile.
- Depreciation: $0.15/mile.
- Insurance, permits, other fixed costs: $0.05/mile.
- You want $30/hour for your time when you're not sitting — averaged over typical loaded speed of 50 mph, that's $0.60/mile.
Now compute:
- Fuel per mile = (1 / 7.0 mpg) * $5.313 = 0.142857 * 5.313 ≈ $0.76/mile.
- Maintenance/tires = $0.12/mile.
- Depreciation = $0.15/mile.
- Insurance/permits = $0.05/mile.
- Time cost = $0.60/mile.
Total deadhead cost/mile = $0.76 + $0.12 + $0.15 + $0.05 + $0.60 =
So if you've got to deadhead 200 miles to the pickup, that's 200 *
If you skip the load and instead run a local $2,000 load that keeps you loaded home, that might beat the long empty move. Do the math.
How to use this on a call with a broker or shipper
- Tell them your required all-in rate. Simple and blunt. They can haggle, you decide.
- Ask about backhauls. If there's a guaranteed freight back, that changes the deadhead math fast.
- If they want you to deadhead for cheap, push for a fuel advance, detention guarantee, or a deadhead credit in the rate.
Don't be coy. You don't owe them your costs, but you do owe yourself the truth.
Why blanket benchmarks lie
You hear people say “never deadhead more than X miles” or “deadhead should be under $Y.” That's lazy advice. Your truck, your mpg, your hourly target, your maintenance plan — they change the math. A 4 mpg HEAVY-rated flatbed and a 7 mpg dry van measure deadhead differently. Run the numbers on your rig.
Use per-load math before you say yes
A per-load profitability calculator lets you drop your exact per-mile costs (like we did above) plus the load's numbers into one place and see the net. HaulProfit is built for that kind of work: it uses your own cost inputs and the load's rate, miles, and accessorials to calculate per-load profitability so you can say yes or no with real math, not gut feelings.
That's not a magic trick. It's honest arithmetic that saves you from taking junk loads.
Quick tips to cut deadhead pain
- Build consistent backhaul partners or lanes. Repeat business beats guessing.
- Be picky about long deadheads that aren't offset by a higher all-in rate.
- Use drop-and-hook when possible — less detention and faster turn.
- If you must deadhead, get compensated: deadhead pay, fuel advance, or a guaranteed detain clause.
- Keep an eye on fuel trends. Gas up smart and route to cheaper fuel when possible.
Takeaway
Deadhead miles are more than fuel. Add fuel, time, wear, depreciation, insurance, and lost opportunity. Work the numbers for your rig. If a load still pays after you include a realistic deadhead-per-mile, take it. If it doesn't, hang up and wait. You're the one spending the dollars.
Frequently asked questions
How do I quickly estimate fuel cost for deadhead miles?
Divide 1 by your truck's mpg, multiply by the diesel price you pay. Example: 1/7 mpg * $5.31 ≈ $0.76 per mile.
Should I include depreciation when pricing deadhead?
Yes. Every mile reduces resale value. Put a realistic cents-per-mile number in your deadhead math so long-term costs aren't ignored.
Can I charge for deadhead when a broker offers a load?
You can push for deadhead pay, fuel advances, or higher all-in rates. If they won't budge and the math doesn't work, say no.
