Model Changeover Cost Calculator at 72% changeover cost scope included: a worked example

This worked example runs the model changeover cost calculator numbers for a tougher week than the baseline: 72% changeover cost scope included instead of the typical 100%. Estimate appliance or HVAC model changeover cost from changeover hours, hourly line cost, cost capture scope, and fixed setup cost.

The inputs for this scenario

  • Model changeover hours: 38 hr (held at the documented default)
  • Loaded line cost during changeover: 420 $ / hr (held at the documented default)
  • Changeover cost scope included: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed setup, tooling, or approval cost: 2,800 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable changeover time cost = model changeover hours × loaded line cost during changeover × changeover cost scope included.
  • Total model changeover cost works out to 14,291 $ at these inputs, and this is the headline figure for the scenario.
  • Loaded line cost during changeover works out to 376 $ / hr at these inputs.
  • Variable changeover time cost works out to 11,491 $ at these inputs.
  • Fixed setup, tooling, or approval cost works out to 2,800 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where changeover cost scope included sits at 100% and the headline result is 18,760 $, this scenario comes in 23.82% below the baseline at 14,291 $.
  • Use it to justify changeover-reduction projects, calculate economic batch size, or price the overhead embedded in short or mixed-model runs. 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 model changeover cost: 14,291 $ (headline result)
  • Loaded line cost during changeover: 376 $ / hr
  • Variable changeover time cost: 11,491 $
  • Fixed setup, tooling, or approval cost: 2,800 $
