Understanding Empty Mile Percentage
How we calculate. Empty % = deadhead miles ÷ total miles × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Empty Mile Percentage case uses empty miles 12000 and total miles 80000. Enter the same figures below to reproduce the worked path.
What is Empty Mile Percentage?
A transportation efficiency KPI. Lower empty miles usually improve cost per loaded mile and emissions intensity.
- Same odometer basis
- Define empty (no revenue freight)
- Lower is better for most fleets
The Formula
Worked Example
Common Use Cases
- Private fleet: repositioning waste
- Carrier scorecards: network balance
- Sustainability: empty-mile intensity
Pro Tips
- Separate intentional backhauls
- Watch seasonal lane imbalance
- Pair with load factor
Limitations: Empty Mile Percentage results are educational logistics and supply-chain planning aids—not SLAs, carrier contracts, or inventory valuation advice. Confirm definitions with your WMS/TMS and finance policies.
