Product Variant Cost Impact at 54% share reaching volume production: a worked example

This worked example runs the product variant cost impact numbers for a tougher week than the baseline: 54% share reaching volume production instead of the typical 75%. Estimates the cost of proliferating product variants across a BOM family by combining per-variant engineering effort with shared PLM setup.

The inputs for this scenario

  • Variant SKUs added: 12 variants (held at the documented default)
  • Engineering and tooling per variant: 4,200 $/variant (held at the documented default)
  • Share reaching volume production: 54 % (the input this scenario stresses; the baseline uses 75)
  • Shared digital thread setup: 9,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total variant impact = SKUs x engineering/tooling per variant x production share + shared PLM setup.
  • Total product variant cost impact cost works out to 36,216 $ at these inputs, and this is the headline figure for the scenario.
  • Product variant cost impact cost per unit works out to 3,018 $ / piece at these inputs.
  • Variable product variant cost impact cost works out to 27,216 $ at these inputs.
  • Fixed product variant cost impact adder works out to 9,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share reaching volume production sits at 75% and the headline result is 46,800 $, this scenario comes in 22.62% below the baseline at 36,216 $.
  • Use it before approving a new variant family or during a SKU-rationalization review to see the true carrying cost of complexity. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total product variant cost impact cost: 36,216 $ (headline result)
  • Product variant cost impact cost per unit: 3,018 $ / piece
  • Variable product variant cost impact cost: 27,216 $
  • Fixed product variant cost impact adder: 9,000 $
