Bottling, Canning & Filling Lines worked example

Changeover Cost at 72% cost allocation share: a worked example

Suppose cost allocation share 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 the cost of switching a bottling or canning line to another package, flavor, label, closure, or case format.

The inputs for this scenario

  • Changeover labor and machine downtime: 3.5 hours (held at the documented default)
  • Blended cost per changeover hour: 240 $ / unit (held at the documented default)
  • Cost allocation share: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed parts, purge and QA setup cost: 650 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Allocated packaging changeover cost = changeover labor and machine downtime × blended cost per changeover hour × allocation share.
  • Packaging changeover cost works out to 1,255 $ changeover cost at these inputs, and this is the headline figure for the scenario.
  • Blended cost per changeover hour works out to 359 $ / hr at these inputs.
  • Allocated packaging changeover cost works out to 605 $ changeover cost at these inputs.
  • Fixed parts, purge, packaging, or QA setup cost works out to 650 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where cost allocation share sits at 100% and the headline result is 1,490 $ changeover cost, this scenario comes in 15.79% below the baseline at 1,255 $ changeover cost.
  • It computes total changeover cost by valuing changeover downtime at a blended hourly rate, applying an allocation share, and adding fixed setup costs. 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

  • Packaging changeover cost: 1,255 $ changeover cost (headline result)
  • Blended cost per changeover hour: 359 $ / hr
  • Allocated packaging changeover cost: 605 $ changeover cost
  • Fixed parts, purge, packaging, or QA setup cost: 650 $
