Fenestration Scrap Cost at 72% scrap cost scope included: a worked example
Here is what the math looks like when conditions slip. We hold every other input steady and drop scrap cost scope included to 72%, then walk the calculation through step by step. Estimate scrap cost from scrap events or scrap quantity, cost per event, scope, and containment adders.
The inputs for this scenario
- scrapped lites, units, or components: 42 items (held at the documented default)
- average cost per scrapped item: 186 $ / item (held at the documented default)
- scrap cost scope included: 72 % (the input this scenario stresses; the baseline uses 100)
- fixed scrap containment and sorting cost: 1,200 $ (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Variable fenestration scrap cost = scrapped lites, units, or components × average cost per scrapped item × scrap cost scope included.
- total fenestration scrap cost works out to 6,825 $ at these inputs, and this is the headline figure for the scenario.
- scrap cost per item works out to 162 $ / piece at these inputs.
- variable fenestration scrap cost works out to 5,625 $ at these inputs.
- fixed scrap containment and sorting cost works out to 1,200 $ at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where scrap cost scope included sits at 100% and the headline result is 9,012 $, this scenario comes in 24.27% below the baseline at 6,825 $.
- The practical read: the gap between this scenario and the baseline is entirely attributable to scrap cost scope included, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses one average cost per scrapped item; if your scrap mixes cheap setup cutoffs with full tempered IGUs, the average can hide where the real money is going.
