Tooling Qualification Payback with qualified tooling investment of 362,500 $: a worked example

This scenario runs the tooling qualification payback calculation on the strong side: qualified tooling investment of 362,500 $, with every other input held at its documented default. a manufacturing engineer needs to justify qualified tooling for a recurring aerospace or defense production program

The inputs for this scenario

  • Qualified tooling investment: 362,500 $ (raised for this scenario; the documented default is 145,000)
  • Annual recurring program savings: 62,000 $ / yr (unchanged)
  • Annual tooling support cost: 8,500 $ / yr (unchanged)

Working through the calculation

  • Applying the documented formula (Net annual qualified-tooling savings = annual recurring savings - annual tooling support cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 6.78 yr payback for tooling qualification payback, the number this scenario is built around.
  • At this operating point the engine returns 53,500 $ / yr for net annual qualified-tooling savings.
  • At this operating point the engine returns 362,500 $ for qualified tooling investment.
  • At this operating point the engine returns -95,000 $ for five-year tooling net value.

How this compares with the baseline

  • Against the tool's baseline example, where qualified tooling investment sits at 145,000 $ and the headline result is 2.71 yr payback, this scenario comes in 150% above the baseline at 6.78 yr payback.
  • Use it when deciding whether to qualify dedicated tooling for a long-run aerospace or defense program rather than using soft or universal tooling. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
