Commercial Vehicle, Bus & Coach Manufacturing worked example

Harness Routing Labor at 72% harness scope included: a worked example in commercial vehicle, bus & coach manufacturing

Suppose harness scope included falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate labor cost for routing wiring harnesses in commercial vehicles, buses, and coaches.

The inputs for this scenario

  • Vehicles requiring harness routing: 16 units (held at the documented default)
  • Harness routing labor cost per vehicle: 2,350 $ / unit (held at the documented default)
  • Harness scope included: 72 % (the input this scenario stresses; the baseline uses 100)
  • Harness fixture, test, and engineering support cost: 5,200 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable harness routing labor = vehicles requiring harness routing × harness routing labor cost per vehicle × harness scope included.
  • total harness routing labor works out to 32,272 $ at these inputs, and this is the headline figure for the scenario.
  • harness routing labor per vehicle works out to 2,017 $ / piece at these inputs.
  • variable harness routing labor works out to 27,072 $ at these inputs.
  • harness fixture, test, and engineering support cost works out to 5,200 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where harness scope included sits at 100% and the headline result is 42,800 $, this scenario comes in 24.6% below the baseline at 32,272 $.
  • It computes total harness routing labor as vehicles times routing labor cost per vehicle (scaled by harness scope included) plus the fixed fixture, test, and engineering support cost. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • total harness routing labor: 32,272 $ (headline result)
  • harness routing labor per vehicle: 2,017 $ / piece
  • variable harness routing labor: 27,072 $
  • harness fixture, test, and engineering support cost: 5,200 $
