Low-Volume Quote Margin at 32% target gross margin: a worked example

This worked example runs the low-volume quote margin numbers for a tougher week than the baseline: 32% target gross margin instead of the typical 45%. Calculate the gross margin on a low-volume or custom instrument quote. Compares quoted revenue against total cost (materials, labor, overhead, NRE) to show the margin percentage and gap to your target margin. Helps sales engineers and product managers verify that custom or low-volume quotes meet minimum profitability requirements before approval.

The inputs for this scenario

  • Quoted revenue: 250,000 $ (held at the documented default)
  • Total estimated cost: 145,000 $ (held at the documented default)
  • Target gross margin: 32 % (the input this scenario stresses; the baseline uses 45)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross margin = (quoted revenue - total cost) / quoted revenue x 100.
  • Gross margin works out to 172 % at these inputs, and this is the headline figure for the scenario.
  • Margin gap to target works out to -140 points at these inputs.
  • Quoted revenue works out to 250,000 count at these inputs.
  • Total estimated cost works out to 145,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target gross margin sits at 45% and the headline result is 172 %, this scenario lands almost exactly on the baseline at 172 %.
  • Use it when pricing a low-volume or custom instrument build and you want to see margin and target variance together. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Gross margin: 172 % (headline result)
  • Margin gap to target: -140 points
  • Quoted revenue: 250,000 count
  • Total estimated cost: 145,000 count
