Coil Manufacturing Cost Calculator at 110% coil cost scope included: a worked example

What does the result look like when coil cost scope included reaches 110%? The full calculation is worked below with real intermediate numbers. an estimator or coil manufacturing engineer needs a cost estimate for a coil build or quote

The inputs for this scenario

  • Coil assemblies produced: 3,200 coils (unchanged)
  • Tube, fin, and labor cost: 28.5 $ / coil (unchanged)
  • Coil cost scope included: 110 % (raised for this scenario; the documented default is 100)
  • Fixed coil setup or tooling cost: 6,400 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable coil manufacturing cost = coil assemblies produced × tube, fin, and labor cost × coil cost scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 106,720 $ for total coil manufacturing cost, the number this scenario is built around.
  • At this operating point the engine returns 33.35 $ / coil for manufacturing cost per coil.
  • At this operating point the engine returns 100,320 $ for variable coil manufacturing cost.
  • At this operating point the engine returns 6,400 $ for fixed coil setup or tooling cost.

How this compares with the baseline

  • Against the tool's baseline example, where coil cost scope included sits at 100% and the headline result is 97,600 $, this scenario comes in 9.34% above the baseline at 106,720 $.
  • A figure at this level is achievable when coil cost scope included is genuinely sustained, not just peaked for a shift. It uses one blended per-coil rate, so it will not reflect material price swings within a run, scrap from fin damage, or different costs across coil sizes in a mixed batch.

Results at a glance

  • Total coil manufacturing cost: 106,720 $ (headline result)
  • Manufacturing cost per coil: 33.35 $ / coil
  • Variable coil manufacturing cost: 100,320 $
  • Fixed coil setup or tooling cost: 6,400 $
