Empty Miles Still Cost Full Price
Fuel, tires, and time behind the wheel cost the same whether or not the trailer is loaded, so deadhead miles carry real expense even though they earn no direct revenue.
Effective Rate Spreads Revenue Across All Miles
A rate that looks strong per loaded mile can look very different once it's divided across total miles driven, deadhead included, which is the number that actually reflects what the run paid.
High Deadhead Signals a Lane or Dispatch Problem
A deadhead percentage that consistently runs high points to a lane, dispatcher, or booking pattern worth revisiting, since it's quietly cutting into effective rate on every run.
Deadhead Miles Calculator: Formula, Benchmarks, and a Worked Example
Deadhead miles, the empty ones you drive without a paying load, don't show up on a rate confirmation but they show up everywhere else: in fuel burned, hours used, and revenue spread thinner across more total miles. This calculator takes your loaded miles, deadhead miles, and revenue for the run, and shows your real effective rate once the empty miles are factored in, along with exactly what those empty miles cost you in dollars.
What Deadhead Percentage Actually Measures
Deadhead percentage is the share of your total miles on a run that were driven empty, with no paying freight aboard. It's calculated across the whole trip, loaded and empty miles combined, so it shows how much of the total distance you covered actually earned revenue versus how much was just repositioning.
The Formula Behind This Calculator
Total miles equals loaded miles plus deadhead miles. Deadhead percentage equals deadhead miles divided by total miles, expressed as a percentage. Effective rate per mile equals your line-haul revenue divided by total miles, not just loaded miles, which is what makes it the more honest number to judge a run by.
Deadhead cost is simply your deadhead miles multiplied by your true cost per mile, giving a dollar figure for exactly what those empty miles cost to drive, independent of whatever revenue the loaded portion brought in.
Realistic Industry Benchmarks
Most over-the-road carriers run somewhere between 10% and 15% deadhead on average, with regional and dedicated lanes often running lower and spot-market freight running higher. A deadhead percentage that climbs above 20% on a regular basis is usually worth investigating, whether the cause is a thin lane, a dispatcher not backhauling efficiently, or a broker relationship worth reconsidering.
A Worked Example
Using this calculator's defaults: 650 loaded miles, 90 deadhead miles, $1,600 in line-haul revenue, and a cost per mile of $1.55. Total miles is 650 plus 90, or 740. Deadhead percentage is 90 divided by 740, or about 12.2%, comfortably inside the typical range.
Effective rate per mile is $1,600 divided by 740 total miles, or about $2.16 a mile, noticeably lower than the roughly $2.46 per loaded mile the rate confirmation might suggest at first glance. Deadhead cost is 90 miles multiplied by $1.55, or $139.50, the real dollar cost of positioning for this particular load.
Why This Number Matters
Judging a load by its rate per loaded mile alone hides the real economics of the run whenever meaningful deadhead is involved. Effective rate per total mile is the number that actually determines whether a run was worth taking once every mile, loaded and empty, is counted against the revenue it produced.
Common Mistakes With This Number
The most common mistake is comparing load offers using rate per loaded mile only, which makes a load with heavy deadhead on either end look more attractive than it really is. The second is not tracking deadhead consistently enough to notice a pattern, like a dispatcher or lane that quietly runs higher empty miles than the rest of the operation.

What Owner-Operators Say
“I always looked at rate per loaded mile and wondered why some good-looking loads didn't actually pay well. The deadhead math explained it instantly.”
“Tracking deadhead percentage by lane showed me exactly which broker was booking me the worst backhauls.”
