Coffee, Tea, Roasting & Dry Goods Processing worked example

Scrap/Rework Cost at 72% affected product scope: a worked example in coffee, tea, roasting & dry goods processing

Here is what the math looks like when conditions slip. We hold every other input steady and drop affected product scope to 72%, then walk the calculation through step by step. Estimate scrap or rework cost from affected product weight, cost per pound, affected scope, and fixed rework or disposal costs.

The inputs for this scenario

  • Scrap or rework product weight: 180 lb (held at the documented default)
  • Cost per affected pound: 7.8 $/lb (held at the documented default)
  • Affected product scope (capture factor): 72 % (the input this scenario stresses; the baseline uses 100)
  • Rework labor, testing, and disposal adders: 260 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable scrap/rework cost = scrap or rework product weight × cost per affected pound × affected product scope.
  • total scrap/rework cost works out to 1,271 $ at these inputs, and this is the headline figure for the scenario.
  • scrap/rework cost per sellable unit works out to 7.06 $ / piece at these inputs.
  • variable scrap/rework cost works out to 1,011 $ at these inputs.
  • rework labor, testing, and disposal adders works out to 260 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where affected product scope sits at 100% and the headline result is 1,664 $, this scenario comes in 23.62% below the baseline at 1,271 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to affected product scope, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It captures direct costs but not the downstream value of lost capacity, expedite fees, or customer goodwill, so for a stockout-driving defect the real cost is higher than this figure.
