Deadhead Miles: How Empty Miles Change What You Earn
A load can pay a rate that looks good on the rate confirmation and still leave you with less than you expected. The usual reason is deadhead: the empty miles you drive to get to the pickup, or to get back to freight after the delivery. This guide explains what deadhead does to your real rate, how to calculate it, and how to decide whether a load is still worth taking.
What deadhead miles are
Deadhead miles are miles you drive with no freight on the truck. The most common case is the empty leg from where you are to the shipper. It also includes driving empty to reposition after a delivery. Brokers pay for the loaded miles between pickup and delivery. The empty miles are yours to absorb, but the truck still burns fuel, wears tires and needs maintenance on them.
Loaded-mile rate versus all-in rate
The rate a broker quotes is usually per loaded mile. Your real result depends on the rate over all the miles you drive for that load. Take a load that pays $2,400 in total (linehaul, fuel surcharge and any extras):
| Measure | Miles | Rate per mile |
|---|---|---|
| Loaded miles only | 800 | $3.00 |
| All miles (800 loaded + 200 empty) | 1,000 | $2.40 |
The load looks like $3.00 per mile but pays you $2.40 for every mile the truck actually travels. The empty miles are 20% of the total, and they cost you 60 cents a mile in the headline rate. That gap never shows on the rate confirmation.
How to calculate your deadhead share
Deadhead share = empty miles ÷ total miles. In the example that is 200 ÷ 1,000 = 20%. Track it over a month as well as per load. A high monthly figure means your lanes or your booking habits leave you repositioning too often.
The rate you need per loaded mile
You already know, or can work out, your cost per mile (see the cost per mile guide). Empty miles change the rate you must ask for on the loaded miles:
Rate needed per loaded mile = your rate per mile × (loaded + empty miles) ÷ loaded miles.
Assume a break-even cost of $1.20 per mile and a target of $1.333 per mile (a 10% margin):
| Empty miles (loaded = 800) | Break-even per loaded mile | 10% target per loaded mile |
|---|---|---|
| 0 | $1.200 | $1.333 |
| 200 | $1.500 | $1.667 |
| 400 | $1.800 | $2.000 |
Doubling the empty miles from 200 to 400 raises the rate you need by 30 cents per loaded mile, because the same costs are spread over fewer paid miles.
Fees change the answer too
Broker, dispatch and factoring fees are usually a percentage of the pay, so they take more as the rate goes up. If those fees total 7%, only 93 cents of each dollar reaches you. To cover $1,200 of cost on 1,000 total miles you would need $1,200 ÷ 0.93 = $1,290.32, which is $1.613 per loaded mile on 800 loaded miles. The load profit calculator handles this automatically and shows the lowest pay worth accepting.
What an empty mile really costs
Your average cost per mile includes fixed costs like the truck payment, which you pay whether the wheels turn or not. The extra cost of driving one more empty mile is the variable part: fuel, tires and maintenance. With the example costs, that is $0.60 + $0.15 + $0.05 = $0.80 per empty mile, so 200 empty miles cost about $160 in real extra spending. This distinction matters when you compare two options. Repositioning 200 miles for a good load costs about $160 in real money, while sitting parked earns nothing and still leaves the fixed costs running.
Practical ways to keep deadhead down
- Look at where the load delivers, not only where it starts. A great rate into an area with little freight can create a long empty leg afterwards. Include the empty miles you expect next in your calculation.
- Ask for more when the pickup is far away. If you must drive 250 miles empty to collect, the rate should reflect that. Use the numbers above to make the request specific.
- Prefer lanes with balanced freight. Regions that both send and receive freight give you loads to move you back out.
- Measure it. Log empty and loaded miles for every trip. What you measure, you can improve.
Deadhead and your fuel tax return
Empty miles matter beyond load pricing. The instructions for the International Fuel Tax Agreement (IFTA) return say that total miles must include every mile driven, including empty, bobtail and off-highway miles. Leaving empty miles out would overstate your fuel economy and skew what you owe each state. See the IFTA guide for how that works.
A simple habit
Before accepting a load, write down three numbers: the loaded miles, the empty miles you will drive to get there, and the pay. Divide the pay by the total miles and compare it with your break-even and target rates. If it falls short, you now know exactly how much to ask for.
