Composite Part Cost at 110% share of part cost included: a worked example

What does the result look like when share of part cost included reaches 110%? The full calculation is worked below with real intermediate numbers. building a quote or cost rollup for composite parts

The inputs for this scenario

  • Composite parts in this cost scope: 36 parts (unchanged)
  • Direct cost per composite part: 1,280 $ / part (unchanged)
  • Share of part cost included: 110 % (raised for this scenario; the documented default is 100)
  • Fixed tooling, engineering, and qualification cost: 6,200 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable composite part cost = composite parts in the cost scope × direct cost per composite part × part cost scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 56,888 $ for total composite part cost, the number this scenario is built around.
  • At this operating point the engine returns 1,580 $ / piece for composite part cost per part or job.
  • At this operating point the engine returns 50,688 $ for variable composite part cost.
  • At this operating point the engine returns 6,200 $ for fixed tooling, engineering, and qualification cost.

How this compares with the baseline

  • Against the tool's baseline example, where share of part cost included sits at 100% and the headline result is 52,280 $, this scenario comes in 8.81% above the baseline at 56,888 $.
  • A figure at this level is achievable when share of part cost included is genuinely sustained, not just peaked for a shift. It assumes a flat direct cost per part; in practice early units cost more as the layup learning curve and first-article inspection are absorbed.

Results at a glance

  • total composite part cost: 56,888 $ (headline result)
  • composite part cost per part or job: 1,580 $ / piece
  • variable composite part cost: 50,688 $
  • fixed tooling, engineering, and qualification cost: 6,200 $
