Masking Material Cost with parts masked of 50 parts: a worked example
Here is what the math looks like when conditions slip. We hold every other input steady and drop parts masked to 50 parts, then walk the calculation through step by step. Calculate masking tape, plug, cap, and disposable material cost for a coating job.
The inputs for this scenario
- Parts masked: 50 parts (the input this scenario stresses; the baseline uses 100)
- Masking material per part: 2.5 $ / part (held at the documented default)
- Setup material cost: 150 $ (held at the documented default)
- Scrap and replacement masks: 75 $ (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Total cost = quantity × unit cost + labor/downtime + overhead.
- Total cost works out to 350 $ / job at these inputs, and this is the headline figure for the scenario.
- Cost per piece works out to 7 $ / piece at these inputs.
- Variable cost works out to 125 $ at these inputs.
- Fixed adders works out to 225 $ at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where parts masked sits at 100 parts and the headline result is 475 $ / job, this scenario comes in 26.32% below the baseline at 350 $ / job.
- The practical read: the gap between this scenario and the baseline is entirely attributable to parts masked, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It covers material only, not the masking and de-masking labor, which on intricate parts often exceeds the material cost itself.
