Reheat Cost at 72% share of reheat cost actually incurred: a worked example

This worked example runs the reheat cost numbers for a tougher week than the baseline: 72% share of reheat cost actually incurred instead of the typical 100%. Estimate reheat cost for loads that must be reheated due to missed soak, failed profile, hardness issue, or process interruption.

The inputs for this scenario

  • Parts or pounds requiring reheat: 80 parts (held at the documented default)
  • Reheat cost per part: 7.5 $ / part (held at the documented default)
  • Share of reheat cost actually incurred: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed reheat setup or lab test charge: 300 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Captured reheat cost = reheated parts or pounds × reheat cost rate × reheat cost capture.
  • Total reheat cost works out to 732 $ at these inputs, and this is the headline figure for the scenario.
  • Reheat cost per part works out to 9.15 $ / part at these inputs.
  • Captured reheat cost works out to 432 $ at these inputs.
  • Fixed reheat setup or lab cost works out to 300 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of reheat cost actually incurred sits at 100% and the headline result is 900 $, this scenario comes in 18.67% below the baseline at 732 $.
  • Use it after a batch fails hardness or case-depth checks to cost the rework, or when weighing reheat against scrap and rework alternatives. 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 reheat cost: 732 $ (headline result)
  • Reheat cost per part: 9.15 $ / part
  • Captured reheat cost: 432 $
  • Fixed reheat setup or lab cost: 300 $
