Wiring Harness Cost Calculator at 110% share of harness spend captured: a worked example

Push share of harness spend captured up to 110% and the picture changes. This example computes every intermediate figure at that operating point. a procurement lead or estimator needs to cost wiring harness content for appliance or HVAC production

The inputs for this scenario

  • Wiring harnesses installed per build run: 4,200 harnesses (unchanged)
  • Purchase or in-house build cost per harness: 9.6 $ / harness (unchanged)
  • Share of harness spend captured: 110 % (raised for this scenario; the documented default is 100)
  • Fixed harness tooling, crimp dies or engineering cost: 1,800 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable wiring harness cost = wiring harnesses used × harness purchase or build cost × harness usage scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 46,152 $ for total wiring harness cost, the number this scenario is built around.
  • At this operating point the engine returns 10.99 $ / harness for cost per wiring harness.
  • At this operating point the engine returns 44,352 $ for variable wiring harness cost.
  • At this operating point the engine returns 1,800 $ for fixed harness tooling or engineering cost.

How this compares with the baseline

  • Against the tool's baseline example, where share of harness spend captured sits at 100% and the headline result is 42,120 $, this scenario comes in 9.57% above the baseline at 46,152 $.
  • It computes the total wiring harness cost (variable harness spend plus fixed tooling/engineering) and the effective cost per harness for a defined build run. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total wiring harness cost: 46,152 $ (headline result)
  • Cost per wiring harness: 10.99 $ / harness
  • Variable wiring harness cost: 44,352 $
  • Fixed harness tooling or engineering cost: 1,800 $
