Truck Dispatch Deadhead Miles Calculator
Dispatcher AI - Updated August 2026
Deadhead miles turn a good-looking rate into a weak load when dispatch only looks at loaded mileage. A $1,500 load over 500 loaded miles looks like $3.00 per mile. Add 125 empty miles to pickup and 75 empty miles after delivery, and the real all-in rate drops to $2.14 per mile before fuel and time costs.
Owner-operators and small fleets should calculate deadhead before accepting a load, not after delivery. The dispatcher needs pickup distance, delivery repositioning, expected fuel cost and the next-load plan in the same decision.
Deadhead calculation inputs
| Input | Why it matters | Dispatch check |
|---|---|---|
| Empty miles to pickup | Shows how much unpaid travel is needed before the load starts. | Measure from current truck position, not from city center. |
| Loaded miles | Sets the broker-facing RPM and linehaul comparison. | Use the mileage basis shown on the rate confirmation. |
| Empty miles after delivery | Captures repositioning needed to reach the next freight market. | Estimate the practical path to a real reload area. |
| Fuel cost | Deadhead burns fuel without revenue. | Apply current diesel price and realistic MPG for equipment type. |
| Next-load probability | Deadhead risk is lower when delivery lands near strong freight. | Check load-board density before accepting the current load. |
Formula for real revenue per mile
All-in RPM = total load revenue / (deadhead to pickup + loaded miles + repositioning deadhead).
If the load pays a fuel surcharge, include it in total revenue only when it is confirmed on the rate confirmation.
Dispatch workflow before accepting
- Locate the truck: use actual GPS or ELD position before estimating pickup deadhead.
- Calculate all miles: add empty-to-pickup, loaded miles and expected delivery repositioning.
- Compare against cost per mile: use all-in miles, not broker miles.
- Check the next market: reject loads that strand the truck unless the rate covers repositioning.
- Document the decision: save the calculation with the rate confirmation for margin review.
How AI dispatch helps
AI dispatch can calculate pickup deadhead from live truck position, compare loaded and all-in RPM, flag loads that land in weak markets, and suggest backhaul options before the dispatcher commits to the broker.
For cost assumptions, use the owner-operator dispatch cost calculator. For fuel math, review truck dispatch fuel surcharge calculation. To reduce empty miles after delivery, use truck backhaul load planning. Before signing, run the truck dispatch rate confirmation checklist.
