Trailers, Truck Bodies & Specialty Vehicles worked example

Wiring Harness Labor at 92% billable labor capture factor: a worked example in trailers, truck bodies & specialty vehicles

What does the result look like when billable labor capture factor reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when wiring harness labor in trailers, truck bodies and specialty vehicles is being put through a trailers, truck bodies and specialty vehicles weighted-cost review.

The inputs for this scenario

  • Harnesses built or labor hours: 100 units (unchanged)
  • Labor cost per harness: 45 $ / unit (unchanged)
  • Billable labor capture factor: 92 % (raised for this scenario; the documented default is 80)
  • Fixed setup and tooling cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Wiring Harness Labor cost = quantity × rate × capture factor + fixed cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for weighted cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for per piece value.
  • At this operating point the engine returns 4,140 $ for captured value.
  • At this operating point the engine returns 250 $ for fixed adjustment.

How this compares with the baseline

  • Against the tool's baseline example, where billable labor capture factor sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • A figure at this level is achievable when billable labor capture factor is genuinely sustained, not just peaked for a shift. It assumes one blended labor rate and capture factor; complex harnesses with mixed skill levels or heavy test time need to be split into separate line items.

Results at a glance

  • Weighted cost: 4,390 $ (headline result)
  • Per piece value: 43.9 $ / piece
  • Captured value: 4,140 $
  • Fixed adjustment: 250 $
