Fire Suppression, Sprinkler & Safety System Products worked example
Unit Cost at 110% allocated cost share: a worked example in fire suppression, sprinkler & safety system products
What does the result look like when allocated cost share reaches 110%? The full calculation is worked below with real intermediate numbers. Use it when costing sprinkler heads, valves, nozzles, detectors, alarm devices, cylinders, extinguishers, or packaged safety-system products.
The inputs for this scenario
- Fire protection units in scope: 250 units (unchanged)
- Variable cost per fire protection unit: 38 $ / unit (unchanged)
- Allocated cost share: 110 % (raised for this scenario; the documented default is 100)
- Fixed setup or documentation cost: 750 $ (unchanged)
Working through the calculation
- Applying the documented formula (Unit Cost = fire protection units in scope × cost per fire protection unit × allocated cost share + fixed setup or documentation cost) to the inputs above produces each figure below.
- At this operating point the engine returns 11,200 $ for total unit cost, the number this scenario is built around.
- At this operating point the engine returns 44.8 $ / unit for average unit cost per unit.
- At this operating point the engine returns 10,450 $ for variable captured cost.
- At this operating point the engine returns 750 $ for fixed setup or documentation cost.
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 9.27% above the baseline at 11,200 $.
- A figure at this level is achievable when allocated cost share is genuinely sustained, not just peaked for a shift. It uses a single blended variable rate and one fixed charge, so it won't capture step-function costs like a second shift, freight tiers, or scrap that scales nonlinearly with volume.
