Inspection Burden at 58% chargeable inspection portion: a worked example

Suppose chargeable inspection portion falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Inspection burden is the loaded quality cost carried by each switchgear or panelboard assembly — the dielectric tests, torque audits, continuity checks and paperwork that a unit must pass before it ships.

The inputs for this scenario

  • Assemblies passing through inspection: 100 units (held at the documented default)
  • Inspection labor & test cost per assembly: 45 $ / unit (held at the documented default)
  • Chargeable inspection portion: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed calibration & setup cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Inspection Burden cost = quantity × rate × capture factor + fixed cost.
  • Weighted cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Per piece value works out to 28.6 $ / piece at these inputs.
  • Captured value works out to 2,610 $ at these inputs.
  • Fixed adjustment works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where chargeable inspection portion sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • It multiplies the number of assemblies by the per-unit inspection cost and a chargeable factor, adds fixed calibration/setup cost, and reports total and per-assembly burden. 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.
