Custom Part Cost at 110% costed quote scope included: a worked example

What does the result look like when costed quote scope included reaches 110%? The full calculation is worked below with real intermediate numbers. building a quote from material, routing, setup, tooling, inspection, and outside service assumptions

The inputs for this scenario

  • Quoted part order quantity: 650 parts (unchanged)
  • Variable cost per custom part: 24.6 $ / part (unchanged)
  • Costed quote scope included: 110 % (raised for this scenario; the documented default is 100)
  • Fixed setup, tooling, and engineering cost: 3,900 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable custom part cost = quoted part order quantity × variable cost per custom part × costed quote scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 21,489 $ for total custom part cost, the number this scenario is built around.
  • At this operating point the engine returns 33.06 $ / piece for variable cost per custom part.
  • At this operating point the engine returns 17,589 $ for variable custom part cost.
  • At this operating point the engine returns 3,900 $ for fixed setup, tooling, and engineering cost.

How this compares with the baseline

  • Against the tool's baseline example, where costed quote scope included sits at 100% and the headline result is 19,890 $, this scenario comes in 8.04% above the baseline at 21,489 $.
  • A figure at this level is achievable when costed quote scope included is genuinely sustained, not just peaked for a shift. It treats variable cost per part as flat across the quantity; if your material or cycle cost steps down with volume, costed scope below 100%, or partial tooling reuse, you must adjust the inputs to reflect that.

Results at a glance

  • total custom part cost: 21,489 $ (headline result)
  • variable cost per custom part: 33.06 $ / piece
  • variable custom part cost: 17,589 $
  • fixed setup, tooling, and engineering cost: 3,900 $
