Wire Harness, Cable & Electromechanical Assembly worked example

Wire Harness Cost at 98% labor efficiency factor: a worked example

This scenario runs the wire harness cost calculation on the strong side: 98% labor efficiency factor, with every other input held at its documented default. Use it when quoting a harness build and you need to separate labor-driven cost from the fixed material and overhead content.

The inputs for this scenario

  • Assembly Build Time: 45 min (unchanged)
  • Fully Loaded Labor Rate: 0.85 $/min (unchanged)
  • Labor Efficiency Factor: 98 % (raised for this scenario; the documented default is 85)
  • Materials and Overhead Adder: 32 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total = build time x labor rate x labor efficiency% + materials and overhead) to the inputs above produces each figure below.
  • At this operating point the engine returns 69.49 $ for total wire harness cost, the number this scenario is built around.
  • At this operating point the engine returns 1.54 $ / piece for wire harness cost per unit.
  • At this operating point the engine returns 37.49 $ for variable wire harness cost.
  • At this operating point the engine returns 32 $ for fixed wire harness cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where labor efficiency factor sits at 85% and the headline result is 64.51 $, this scenario comes in 7.71% above the baseline at 69.49 $.
  • Use it when quoting a new harness, re-costing after a routing or process change, or validating a supplier's price. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total wire harness cost: 69.49 $ (headline result)
  • Wire harness cost per unit: 1.54 $ / piece
  • Variable wire harness cost: 37.49 $
  • Fixed wire harness cost adder: 32 $
