Fire Suppression, Sprinkler & Safety System Products worked example

Unit Cost at 72% allocated cost share: a worked example in fire suppression, sprinkler & safety system products

This worked example runs the unit cost numbers for a tougher week than the baseline: 72% allocated cost share instead of the typical 100%. Estimate fire protection product unit cost from units in scope, cost per unit, allocation share, and fixed setup or documentation cost.

The inputs for this scenario

  • Fire protection units in scope: 250 units (held at the documented default)
  • Variable cost per fire protection unit: 38 $ / unit (held at the documented default)
  • Allocated cost share: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed setup or documentation cost: 750 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Unit Cost = fire protection units in scope × cost per fire protection unit × allocated cost share + fixed setup or documentation cost.
  • Total unit cost works out to 7,590 $ at these inputs, and this is the headline figure for the scenario.
  • Average unit cost per unit works out to 30.36 $ / unit at these inputs.
  • Variable captured cost works out to 6,840 $ at these inputs.
  • Fixed setup or documentation cost works out to 750 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where allocated cost share sits at 100% and the headline result is 10,250 $, this scenario comes in 25.95% below the baseline at 7,590 $.
  • Use it when quoting a fire-protection run, comparing make quantities, or deciding how much a compliance documentation package adds to each device's cost. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total unit cost: 7,590 $ (headline result)
  • Average unit cost per unit: 30.36 $ / unit
  • Variable captured cost: 6,840 $
  • Fixed setup or documentation cost: 750 $
