Parts Washing Cost at 110% share of batch actually washed: a worked example
This scenario runs the parts washing cost calculation on the strong side: 110% share of batch actually washed, with every other input held at its documented default. Use it when quoting a parts washing job, comparing in-house and outsourced cleaning, or checking whether cleaning cost is material to part margin.
The inputs for this scenario
- Parts to wash in the batch: 12,500 parts (unchanged)
- Cleaning cost per part: 0.18 $ / part (unchanged)
- Share of batch actually washed: 110 % (raised for this scenario; the documented default is 100)
- Fixed wash line setup and validation cost: 650 $ (unchanged)
Working through the calculation
- Applying the documented formula (Variable parts washing cost = parts to wash × cleaning cost per part × cleaning scope included) to the inputs above produces each figure below.
- At this operating point the engine returns 3,125 $ for total parts washing cost, the number this scenario is built around.
- At this operating point the engine returns 0.25 $ / part for cleaning cost per part.
- At this operating point the engine returns 2,475 $ for variable parts washing cost.
- At this operating point the engine returns 650 $ for fixed wash setup and validation cost.
How this compares with the baseline
- Against the tool's baseline example, where share of batch actually washed sits at 100% and the headline result is 2,900 $, this scenario comes in 7.76% above the baseline at 3,125 $.
- Use it when quoting cleaning operations, costing a wash line, or deciding batch sizes where fixed setup cost dominates. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
