Raw Material Yield with purchased material of 600 lb: a worked example

Suppose purchased material falls to 600 lb. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate usable material yield after trim, kerf, scrap, and conversion loss.

The inputs for this scenario

  • Purchased material: 600 lb (the input this scenario stresses; the baseline uses 1,200)
  • Usable output: 1,035 lb (held at the documented default)
  • Trim loss: 85 lb (held at the documented default)
  • Scrap / kerf loss: 60 lb (held at the documented default)
  • Material cost: 1.85 $ / lb (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Yield = usable output รท purchased material.
  • Raw material yield works out to 100 % at these inputs, and this is the headline figure for the scenario.
  • Total loss works out to 0 lb at these inputs.
  • Known process loss works out to 145 lb at these inputs.
  • Loss cost works out to 0 $ at these inputs.
  • Usable material cost works out to 1.85 $ / usable lb at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where purchased material sits at 1,200 lb and the headline result is 86.25 %, this scenario comes in 15.94% above the baseline at 100 %.
  • It computes the percentage of purchased material that becomes usable output, the total and known process loss in pounds, the dollar cost of that loss, and the effective cost per usable pound. 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.

Results at a glance

  • Raw material yield: 100 % (headline result)
  • Total loss: 0 lb
  • Known process loss: 145 lb
  • Loss cost: 0 $
  • Usable material cost: 1.85 $ / usable lb
