Cleanroom Cost Per Part with total cleanroom operating cost of 112,500 $: a worked example

What does the result look like when total cleanroom operating cost reaches 112,500 $? The full calculation is worked below with real intermediate numbers. Use this to determine the cleanroom cost burden per device for product costing, transfer pricing, or make-vs-buy analysis for cleanroom operations.

The inputs for this scenario

  • Total cleanroom operating cost (period): 112,500 $ (raised for this scenario; the documented default is 45,000)
  • Parts produced in cleanroom (period): 12,000 devices (unchanged)
  • Allocation adjustment factor: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Cleanroom cost per part ratio = total cleanroom operating cost รท total parts produced in cleanroom) to the inputs above produces each figure below.
  • At this operating point the engine returns 9.38 $ / part for cleanroom cost per part, the number this scenario is built around.
  • At this operating point the engine returns 9.38 value for raw ratio.
  • At this operating point the engine returns 1 x for conversion factor.
  • At this operating point the engine returns 12,000 value for total parts produced.

How this compares with the baseline

  • Against the tool's baseline example, where total cleanroom operating cost sits at 45,000 $ and the headline result is 3.75 $ / part, this scenario comes in 150% above the baseline at 9.38 $ / part.
  • A figure at this level is achievable when total cleanroom operating cost is genuinely sustained, not just peaked for a shift. It assumes parts consume cleanroom resources equally; a part needing twice the dwell time or floor area is undercharged unless you reflect that in the allocation factor.

Results at a glance

  • Cleanroom cost per part: 9.38 $ / part (headline result)
  • Raw ratio: 9.38 value
  • Conversion factor: 1 x
  • Total parts produced: 12,000 value
