Low-Volume Quote Margin at 52% target gross margin: a worked example

What does the result look like when target gross margin reaches 52%? The full calculation is worked below with real intermediate numbers. Use when reviewing a quote for a custom instrument build, small production run, or modified standard product. Low-volume scientific instrument orders (1 to 20 units) carry higher per-unit costs and need careful margin verification to avoid unprofitable commitments.

The inputs for this scenario

  • Quoted revenue: 250,000 $ (unchanged)
  • Total estimated cost: 145,000 $ (unchanged)
  • Target gross margin: 52 % (raised for this scenario; the documented default is 45)

Working through the calculation

  • Applying the documented formula (Gross margin = (quoted revenue - total cost) / quoted revenue x 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 172 % for gross margin, the number this scenario is built around.
  • At this operating point the engine returns -120 points for margin gap to target.
  • At this operating point the engine returns 250,000 count for quoted revenue.
  • At this operating point the engine returns 145,000 count for total estimated cost.

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 %.
  • A figure at this level is achievable when target gross margin is genuinely sustained, not just peaked for a shift. Gross margin here is profit over revenue; the margin-gap line simply subtracts your target, so confirm your revenue and cost inputs are on the same scope or the gap will mislead.
