Wire Harness, Cable & Electromechanical Assembly worked example

Test Fixture Payback with test fixture build & tooling cost of 12,500 $: a worked example

This worked example runs the test fixture payback numbers for a tougher week than the baseline: test fixture build & tooling cost of 12,500 $ instead of the typical 25,000 $. Estimate test fixture payback for wire harness, cable and electromechanical assembly using production-ready inputs so teams can screen a capital project before a detailed business case.

The inputs for this scenario

  • Test fixture build & tooling cost: 12,500 $ (the input this scenario stresses; the baseline uses 25,000)
  • Annual labor & scrap savings from fixture: 18,000 $ / yr (held at the documented default)
  • Annual fixture maintenance & calibration cost: 2,500 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net annual test fixture payback savings = annual test fixture payback savings - annual test fixture payback support cost.
  • Test fixture payback payback period works out to 0.81 yr at these inputs, and this is the headline figure for the scenario.
  • Net annual test fixture payback savings works out to 15,500 $ / yr at these inputs.
  • Test fixture payback investment works out to 12,500 $ at these inputs.
  • Five-year net test fixture payback value works out to 65,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where test fixture build & tooling cost sits at 25,000 $ and the headline result is 1.61 yr, this scenario comes in 50% below the baseline at 0.81 yr.
  • Use it during capital-approval or make-versus-buy decisions, before committing to a custom test fixture for a new harness or cable program. 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.

Results at a glance

  • Test fixture payback payback period: 0.81 yr (headline result)
  • Net annual test fixture payback savings: 15,500 $ / yr
  • Test fixture payback investment: 12,500 $
  • Five-year net test fixture payback value: 65,000 $
