Doors, Hardware & Access Control Manufacturing worked example

Packaging Damage Reserve at 58% expected damage occurrence share: a worked example in doors, hardware & access control manufacturing

Suppose expected damage occurrence share falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate reserve for freight, jobsite, and handling damage to doors, frames, hardware kits, access-control devices, glass kits, thresholds, and finished openings.

The inputs for this scenario

  • Shipped openings or packages: 100 openings or packages (held at the documented default)
  • Expected damage cost per opening or package: 45 $ / opening (held at the documented default)
  • Expected damage occurrence share: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed packaging test or claims reserve: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Expected variable damage reserve = shipped openings or packages × expected damage cost per opening or package × expected damage occurrence share.
  • Total packaging damage reserve works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Damage reserve per shipped opening works out to 28.6 $ / piece at these inputs.
  • Expected variable damage reserve works out to 2,610 $ at these inputs.
  • Fixed packaging test or claims reserve works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected damage occurrence share sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • It computes the total damage reserve as expected per-shipment damage cost times occurrence rate across all shipments, plus a fixed testing and claims reserve. 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 packaging damage reserve: 2,860 $ (headline result)
  • Damage reserve per shipped opening: 28.6 $ / piece
  • Expected variable damage reserve: 2,610 $
  • Fixed packaging test or claims reserve: 250 $
