Color Changeover Reduction with avoided color changes of 250 parts: a worked example
Push avoided color changes up to 250 parts and the picture changes. This example computes every intermediate figure at that operating point. Use this calculator for practical powder coating or surface finishing planning, quoting, troubleshooting, or line setup.
The inputs for this scenario
- Avoided color changes: 250 parts (raised for this scenario; the documented default is 100)
- Savings per change: 2.5 $ / part (unchanged)
- Labor savings: 150 $ (unchanged)
- Purge waste and downtime savings: 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 $ / week 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 avoided color changes sits at 100 parts and the headline result is 475 $ / week, this scenario comes in 78.95% above the baseline at 850 $ / week.
- Computes total weekly savings and savings per avoided change by combining variable per-change savings with fixed labor and purge-waste-and-downtime savings. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
