Industrial Fans, Blowers & Air Movement Equipment worked example

Cost Per Blower at 72% included build scope: a worked example

Suppose included build scope falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate cost per blower or fan from build count, loaded cost per unit, included scope, and fixed engineering or test cost.

The inputs for this scenario

  • Fan or blower build count: 12 fans (held at the documented default)
  • Loaded cost per blower: 6,800 $ / blower (held at the documented default)
  • Included build scope: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed engineering and test cost: 9,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable blower build cost = fan or blower build count × loaded cost per blower × included build scope.
  • Total blower build cost works out to 68,252 $ at these inputs, and this is the headline figure for the scenario.
  • Loaded cost per blower works out to 5,688 $ / blower at these inputs.
  • Variable blower build cost works out to 58,752 $ at these inputs.
  • Fixed engineering and test cost works out to 9,500 $ at these inputs.

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 25.08% below the baseline at 68,252 $.
  • It computes total batch build cost as (build count x loaded unit cost x included scope) plus a fixed engineering and test charge, then back-solves the effective loaded cost per blower. 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.

Results at a glance

  • Total blower build cost: 68,252 $ (headline result)
  • Loaded cost per blower: 5,688 $ / blower
  • Variable blower build cost: 58,752 $
  • Fixed engineering and test cost: 9,500 $
