Cleaning Rework Cost at 72% rework scope included: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop rework scope included to 72%, then walk the calculation through step by step. Estimate cost of rewashing or reworking parts that fail cleanliness requirements.

The inputs for this scenario

  • Parts requiring cleaning rework: 420 parts (held at the documented default)
  • Rework cost per part: 1.85 $ / part (held at the documented default)
  • Rework scope included: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed containment and retest cost: 350 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable cleaning rework cost = parts requiring cleaning rework × rework cost per part × rework scope included.
  • Total cleaning rework cost works out to 909 $ at these inputs, and this is the headline figure for the scenario.
  • Rework cost per part works out to 2.17 $ / part at these inputs.
  • Variable cleaning rework cost works out to 559 $ at these inputs.
  • Fixed containment and retest cost works out to 350 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where rework scope included sits at 100% and the headline result is 1,127 $, this scenario comes in 19.3% below the baseline at 909 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to rework scope included, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It costs the rework event itself, not the downstream consequences such as a missed shipment, expedite freight, or a customer line-down charge, which can far exceed the rework dollars.

Results at a glance

  • Total cleaning rework cost: 909 $ (headline result)
  • Rework cost per part: 2.17 $ / part
  • Variable cleaning rework cost: 559 $
  • Fixed containment and retest cost: 350 $
