Fiber Optic Cable & Photonic Interconnects worked example

Quote Margin with quoted sell price for optical scope of 9,300 $: a worked example in fiber optic cable & photonic interconnects

Suppose quoted sell price for optical scope falls to 9,300 $. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate quote margin for fiber optic or photonic interconnect work by comparing quoted sell price with estimated cost.

The inputs for this scenario

  • Quoted sell price for optical scope: 9,300 $ (the input this scenario stresses; the baseline uses 18,500)
  • Estimated total build cost: 14,200 $ (held at the documented default)
  • Reference quote value: 18,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Quote margin dollars = quoted sell price - estimated total build cost.
  • Quote margin works out to -26.49 % at these inputs, and this is the headline figure for the scenario.
  • Quote margin dollars works out to -4,900 $ at these inputs.
  • Quoted sell price works out to 9,300 $ at these inputs.
  • Estimated build cost works out to 14,200 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where quoted sell price for optical scope sits at 18,500 $ and the headline result is 23.24 %, this scenario comes in 214% below the baseline at -26.49 %.
  • It subtracts estimated total build cost from the quoted sell price to get margin dollars, then divides by the reference quote value to get margin percent. 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.
