Deadhead miles: calculate and cut the cost

Two numbers tell you what deadhead is doing to a load: your deadhead percentage and your effective rate per mile. Both take about ten seconds to figure, and both use the same input: total miles, not loaded miles.

Deadhead percentage = deadhead miles ÷ total miles × 100. Effective RPM = total pay ÷ total miles. That is the whole toolkit. The rest of this guide is how to use it on real loads.

Calculate your deadhead percentage

Add your empty miles to your loaded miles to get total miles, then divide the empty miles by that total. Say a broker offers a load picking up 120 miles from where you sit.

For context: under 10% is tight, and ATRI's 2025 operational costs update found deadhead averaged 16.7% of total truck miles in 2024. If your weekly number sits above 20%, one mile in five is working for free.

See what deadhead does to your rate per mile

The rate per mile a broker quotes is usually loaded RPM: pay divided by loaded miles. It flatters the load. Effective RPM divides the same pay by total miles and tells the truth. The gap between loaded and effective RPM is exactly what deadhead costs you in rate.

That $2.50 was never real. With 120 empty miles, this is a $2.00 load, and a closer pickup at a lower sticker rate could beat it. Effective RPM is the only rate-per-mile number worth comparing across loads.

What counts as a deadhead mile

Count every empty mile from where the truck sits to the pickup, including any empty hop after your last drop. The key is consistency: if you count deadhead one way on Monday and another way on Thursday, your comparisons break.

Track it weekly too, not just per load. Add up the week's empty miles and divide by the week's total miles. A single 150-mile reposition can be fine; a 25% weekly average is a pattern that needs fixing.

Run the numbers before you book

Do this math before you call the broker back, not after. Put loaded miles, deadhead miles, and the offered rate into the free calculator and it returns the deadhead percentage and effective RPM alongside whether the load clears your minimum.

From there, two follow-ups: what those empty miles cost in fuel and wear is covered in deadhead and fuel math, and shrinking the percentage itself is strategy, covered in backhauls and positioning.
