Understanding Empty Mile Percentage
How we calculate. Empty % = deadhead miles ÷ total miles × 100. 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
| Scenario | When to use |
|---|---|
| Percent of a number | Finding a part of a whole (tax, tip, score) |
| Percent change | Comparing old vs new values |
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.
Common mistakes
- Swapping part and whole: The denominator must be the full total, not a subset.
- Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
- Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
