Coating Defect Cost with defective coated parts of 250 parts: a worked example
What does the result look like when defective coated parts reaches 250 parts? The full calculation is worked below with real intermediate numbers. Use this calculator for practical powder coating or surface finishing planning, quoting, troubleshooting, or line setup.
The inputs for this scenario
- Defective coated parts: 250 parts (raised for this scenario; the documented default is 100)
- Rework cost per defect: 2.5 $ / part (unchanged)
- Inspection and sorting labor: 150 $ (unchanged)
- Scrap or downtime burden: 75 $ (unchanged)
Working through the calculation
- Applying the documented formula (Total cost = quantity × unit cost + labor/downtime + overhead) to the inputs above produces each figure below.
- At this operating point the engine returns 850 $ for total cost, the number this scenario is built around.
- At this operating point the engine returns 3.4 $ / piece for cost per piece.
- At this operating point the engine returns 625 $ for variable cost.
- At this operating point the engine returns 225 $ for fixed adders.
How this compares with the baseline
- Against the tool's baseline example, where defective coated parts sits at 100 parts and the headline result is 475 $, this scenario comes in 78.95% above the baseline at 850 $.
- A figure at this level is achievable when defective coated parts is genuinely sustained, not just peaked for a shift. It captures direct and burden costs but not downstream effects like a lost customer, expedite freight, or warranty claims from defects that escape.
