Custom Option Burden at 110% custom option scope captured: a worked example

What does the result look like when custom option scope captured reaches 110%? The full calculation is worked below with real intermediate numbers. an estimator needs to recover cost from non-standard elevator or escalator options

The inputs for this scenario

  • Custom options in scope: 9 options (unchanged)
  • Burden cost per custom option: 650 $ / option (unchanged)
  • Custom option scope captured: 110 % (raised for this scenario; the documented default is 100)
  • Fixed engineering and configuration cost: 2,200 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable custom option burden = custom options in scope × burden cost per custom option × custom option scope captured) to the inputs above produces each figure below.
  • At this operating point the engine returns 8,635 $ for total custom option burden, the number this scenario is built around.
  • At this operating point the engine returns 959 $ / option for burden per custom option.
  • At this operating point the engine returns 6,435 $ for variable custom option burden.
  • At this operating point the engine returns 2,200 $ for engineering and configuration cost.

How this compares with the baseline

  • Against the tool's baseline example, where custom option scope captured sits at 100% and the headline result is 8,050 $, this scenario comes in 7.27% above the baseline at 8,635 $.
  • A figure at this level is achievable when custom option scope captured is genuinely sustained, not just peaked for a shift. It applies one average burden per option, so a mix of trivial finish changes and complex dispatch logic should be split into separate runs.

Results at a glance

  • Total custom option burden: 8,635 $ (headline result)
  • Burden per custom option: 959 $ / option
  • Variable custom option burden: 6,435 $
  • Engineering and configuration cost: 2,200 $
