Material Cost Per Part at 58% material yield: a worked example

Suppose material yield falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Material Cost Per Part is the true blank-material cost baked into each stamped piece once you account for nesting yield and fixed lot costs like coil handling and scrap credits.

The inputs for this scenario

  • Parts in the lot: 100 units (held at the documented default)
  • Blank coil cost per part: 45 $ / unit (held at the documented default)
  • Material yield (nesting utilization): 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed coil handling & scrap-credit cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Material Cost Per Part cost = quantity × rate × capture factor + fixed cost.
  • Weighted cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Per piece value works out to 28.6 $ / piece at these inputs.
  • Captured value works out to 2,610 $ at these inputs.
  • Fixed adjustment works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where material yield sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • It computes total lot material cost as quantity times coil cost times yield factor plus a fixed cost, then divides by quantity for per-piece material cost. 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.
