Small-Batch Setup Cost at 110% share of setup billed to this run: a worked example

What does the result look like when share of setup billed to this run reaches 110%? The full calculation is worked below with real intermediate numbers. Use when quoting a limited edition, custom order, or short production run to understand how setup costs affect per-piece pricing. Helps job shops and boutique manufacturers decide minimum order quantities and set appropriate small-batch surcharges.

The inputs for this scenario

  • Batch size: 25 pieces (unchanged)
  • Variable setup cost per piece: 8 $ / piece (unchanged)
  • Share of setup billed to this run: 110 % (raised for this scenario; the documented default is 100)
  • Fixed setup cost: 350 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable setup total = batch size × variable setup cost per piece × production share / 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 570 $ for total batch setup cost, the number this scenario is built around.
  • At this operating point the engine returns 22.8 $ / piece for setup cost per piece.
  • At this operating point the engine returns 220 $ for variable setup total.
  • At this operating point the engine returns 350 $ for fixed setup cost.

How this compares with the baseline

  • Against the tool's baseline example, where share of setup billed to this run sits at 100% and the headline result is 550 $, this scenario comes in 3.64% above the baseline at 570 $.
  • A figure at this level is achievable when share of setup billed to this run is genuinely sustained, not just peaked for a shift. It assumes a single fixed setup charge for the run; jobs needing multiple distinct setups or re-tooling mid-run will cost more, and the share allocation is a judgment call you must justify.
