Color Changeover Reduction with avoided color changes of 50 parts: a worked example

Suppose avoided color changes falls to 50 parts. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate savings from reducing powder or paint color changeover time, labor, purge waste, and downtime.

The inputs for this scenario

  • Avoided color changes: 50 parts (the input this scenario stresses; the baseline uses 100)
  • Savings per change: 2.5 $ / part (held at the documented default)
  • Labor savings: 150 $ (held at the documented default)
  • Purge waste and downtime savings: 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 $ / week 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 avoided color changes sits at 100 parts and the headline result is 475 $ / week, this scenario comes in 26.32% below the baseline at 350 $ / 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. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
