Fiber Optic Cable & Photonic Interconnects calculator

Quote Margin Calculator

Fiber optic quotes must cover cable, connectors, ferrules, labor, polishing, splicing, optical testing, packaging, scrap, rework risk, and customer documentation. This calculator compares quoted price with estimated cost to show margin headroom.

What this calculator does

  • Calculate quote margin for fiber optic or photonic interconnect work by comparing quoted sell price with estimated cost.
  • Use it when reviewing quotes for patch cords, MPO trunks, fanouts, cassettes, transceiver-related assemblies, or custom photonic interconnect builds.
  • Compares quoted sell price with estimated optical assembly cost to calculate margin.

Formula used

  • Quote margin dollars = quoted sell price - estimated total build cost
  • Margin percent = quote margin dollars รท reference quote value

Inputs explained

  • Quoted sell price for optical scope: Use the quoted revenue for the same assembly, lot, program, or customer option.
  • Estimated total build cost: Include cable, connectors, ferrules, labor, test, packaging, scrap allowance, overhead, and support cost as applicable.
  • Reference quote value: Usually use quoted sell price so the margin percent is margin divided by revenue.

How to use the result

  • Use it for commercial reviews, bid/no-bid decisions, pricing changes, option comparisons, and checking whether yield or test assumptions still support the quote.
  • It is only as accurate as the cost model; confirm material prices, labor standards, yield, test time, packaging, freight, and customer requirements before committing price.

Common questions

  • What costs should be included? Include cable, connectors, ferrules, adapters, splices, labor, polish, test, packaging, scrap allowance, rework risk, overhead, and documentation if they apply.
  • Should the reference value be price or cost? Most quote reviews use sell price so margin percent equals margin dollars divided by revenue. Use another reference only if your pricing policy requires it.
  • What does a negative margin mean? Estimated cost is higher than quoted price for the entered scope, so the quote should be reviewed before release.
  • What decision does this support? Use margin to decide whether to accept the quote, revise price, change design, negotiate material cost, or improve yield assumptions.
