Industrial Fans, Blowers & Air Movement Equipment worked example

Cost Per Blower at 110% included build scope: a worked example

What does the result look like when included build scope reaches 110%? The full calculation is worked below with real intermediate numbers. Use it when quoting centrifugal blowers, axial fans, exhaust fans, supply fans, or custom air movement assemblies.

The inputs for this scenario

  • Fan or blower build count: 12 fans (unchanged)
  • Loaded cost per blower: 6,800 $ / blower (unchanged)
  • Included build scope: 110 % (raised for this scenario; the documented default is 100)
  • Fixed engineering and test cost: 9,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable blower build cost = fan or blower build count × loaded cost per blower × included build scope) to the inputs above produces each figure below.
  • At this operating point the engine returns 99,260 $ for total blower build cost, the number this scenario is built around.
  • At this operating point the engine returns 8,272 $ / blower for loaded cost per blower.
  • At this operating point the engine returns 89,760 $ for variable blower build cost.
  • At this operating point the engine returns 9,500 $ for fixed engineering and test cost.

How this compares with the baseline

  • Against the tool's baseline example, where included build scope sits at 100% and the headline result is 91,100 $, this scenario comes in 8.96% above the baseline at 99,260 $.
  • A figure at this level is achievable when included build scope is genuinely sustained, not just peaked for a shift. It assumes one flat loaded cost per blower; mixed wheel sizes, materials (carbon vs. stainless vs. FRP), or motor frames in the same order need separate runs or a blended rate.

Results at a glance

  • Total blower build cost: 99,260 $ (headline result)
  • Loaded cost per blower: 8,272 $ / blower
  • Variable blower build cost: 89,760 $
  • Fixed engineering and test cost: 9,500 $
