Tube, Pipe & Profile Forming worked example

Cost Per Formed Tube at 58% share of cost that is chargeable: a worked example

This worked example runs the cost per formed tube numbers for a tougher week than the baseline: 58% share of cost that is chargeable instead of the typical 80%. Cost Per Formed Tube converts a run's variable forming cost, a chargeable-cost factor and fixed setup into a defensible piece price for bent, roll-formed or end-formed tube.

The inputs for this scenario

  • Formed tubes in the run: 100 units (held at the documented default)
  • Variable forming cost per tube: 45 $ / unit (held at the documented default)
  • Share of cost that is chargeable: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed setup & tooling amortization: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Cost Per Formed Tube cost = quantity × rate × capture factor + fixed cost.
  • Weighted cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Per piece value works out to 28.6 $ / piece at these inputs.
  • Captured value works out to 2,610 $ at these inputs.
  • Fixed adjustment works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of cost that is chargeable sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • Use it when quoting a tube-forming job, comparing short versus long run economics, or checking how setup amortization moves piece price. 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.
