Cost Per Seal at 110% cost allocation share: a worked example

This scenario runs the cost per seal calculation on the strong side: 110% cost allocation share, with every other input held at its documented default. Use it when quoting molded seals, die-cut gaskets, O-rings, extruded seals, adhesive-backed gaskets, or custom elastomer components and the estimator needs a practical finished cost.

The inputs for this scenario

  • Finished seals or gaskets: 5,000 seals (unchanged)
  • Variable cost per seal: 0.42 $ / seal (unchanged)
  • Cost allocation share: 110 % (raised for this scenario; the documented default is 100)
  • Fixed setup or tooling cost: 850 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable finished seal cost = finished seals or gaskets × variable cost per seal × cost allocation share) to the inputs above produces each figure below.
  • At this operating point the engine returns 3,160 $ for total finished seal cost, the number this scenario is built around.
  • At this operating point the engine returns 0.63 $ / piece for finished cost per seal.
  • At this operating point the engine returns 2,310 $ for variable finished seal cost.
  • At this operating point the engine returns 850 $ for fixed setup or tooling cost.

How this compares with the baseline

  • Against the tool's baseline example, where cost allocation share sits at 100% and the headline result is 2,950 $, this scenario comes in 7.12% above the baseline at 3,160 $.
  • Use it when quoting a job, setting an MOQ, or comparing the unit economics of running a tool at different batch sizes. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total finished seal cost: 3,160 $ (headline result)
