Harness Quote Cost at 61% margin realization factor: a worked example

Suppose margin realization factor falls to 61%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Build a harness quote by combining per-unit build cost, the margin actually realized and one-time NRE and sample charges.

The inputs for this scenario

  • Harnesses in the quoted lot: 500 units (held at the documented default)
  • Build cost per harness: 42 $/unit (held at the documented default)
  • Margin realization factor: 61 % (the input this scenario stresses; the baseline uses 85)
  • NRE, tooling & first-article charge: 2,200 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total = harnesses x build cost x margin realization% + NRE charge.
  • Total harness quote cost works out to 15,010 $ at these inputs, and this is the headline figure for the scenario.
  • Harness quote cost per unit works out to 30.02 $ / piece at these inputs.
  • Variable harness quote cost works out to 12,810 $ at these inputs.
  • Fixed harness quote cost adder works out to 2,200 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where margin realization factor sits at 85% and the headline result is 20,050 $, this scenario comes in 25.14% below the baseline at 15,010 $.
  • It multiplies lot size by build cost and margin realization to get variable cost, adds the fixed NRE charge for a total, and divides by lot size for a per-harness price. 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.
