Casting Cleaning Labor with cleaning labor hours per hour of casting production of 1.5 hr / hr: a worked example

This worked example runs the casting cleaning labor numbers for a tougher week than the baseline: cleaning labor hours per hour of casting production of 1.5 hr / hr instead of the typical 3 hr / hr. Estimate cleaning, cutoff, grinding, fettling, and finishing labor cost for castings.

The inputs for this scenario

  • Cleaning labor hours per hour of casting production: 1.5 hr / hr (the input this scenario stresses; the baseline uses 3)
  • Cleaning department runtime this run: 8 hr (held at the documented default)
  • Burdened cleaning labor cost: 38 $ / hr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Casting Cleaning Labor consumed = cleaning labor hours per hour of production × cleaning runtime.
  • Casting Cleaning Labor run cost works out to 456 $ at these inputs, and this is the headline figure for the scenario.
  • Casting Cleaning Labor consumed works out to 12 units at these inputs.
  • Cleaning runtime works out to 8 hr at these inputs.
  • Burdened cleaning labor cost works out to 38 $ / unit at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where cleaning labor hours per hour of casting production sits at 3 hr / hr and the headline result is 912 $, this scenario comes in 50% below the baseline at 456 $.
  • Use it when quoting a new casting, building a standard cost, or auditing why finishing labor on a job ran over budget. 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

  • Casting Cleaning Labor run cost: 456 $ (headline result)
  • Casting Cleaning Labor consumed: 12 units
  • Cleaning runtime: 8 hr
  • Burdened cleaning labor cost: 38 $ / unit
