Housing Coating Cost at 110% full coating share: a worked example

Push full coating share up to 110% and the picture changes. This example computes every intermediate figure at that operating point. Use this when costing a fixture housing production run, comparing powder coat vs. anodize cost, evaluating a new coating supplier, or reviewing where housing coating sits within total fixture BOM cost.

The inputs for this scenario

  • Housings in batch: 600 housings (unchanged)
  • Coating cost per housing: 6.5 $ / housing (unchanged)
  • Full coating share: 110 % (raised for this scenario; the documented default is 100)
  • Fixed line setup cost: 320 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable coating cost = housings in batch x coating cost per housing x full coating share%) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,610 $ for total housing coating cost, the number this scenario is built around.
  • At this operating point the engine returns 7.68 $ / piece for coating cost per housing.
  • At this operating point the engine returns 4,290 $ for variable coating cost.
  • At this operating point the engine returns 320 $ for fixed line setup cost.

How this compares with the baseline

  • Against the tool's baseline example, where full coating share sits at 100% and the headline result is 4,220 $, this scenario comes in 9.24% above the baseline at 4,610 $.
  • It computes total housing coating cost as variable per-housing coating cost across the coated share plus the fixed line setup cost. 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 housing coating cost: 4,610 $ (headline result)
  • Coating cost per housing: 7.68 $ / piece
  • Variable coating cost: 4,290 $
  • Fixed line setup cost: 320 $
