Tooling, Fixtures, Dies & Mold Economics worked example

Fixture Utilization at 61% target fixture utilization: a worked example in tooling, fixtures, dies & mold economics

Here is what the math looks like when conditions slip. We hold every other input steady and drop target fixture utilization to 61%, then walk the calculation through step by step. Estimate fixture utilization for tooling, fixtures, dies and mold economics using production-ready inputs so teams can see how heavily a resource is loaded against its target.

The inputs for this scenario

  • Hours the fixture was in productive use: 360 value (held at the documented default)
  • Hours the fixture was available to run: 480 value (held at the documented default)
  • Target fixture utilization: 61 % (the input this scenario stresses; the baseline uses 85)

Working through the calculation

  • The calculation starts from the formula this tool documents: Fixture utilization = used fixture utilization amount รท available fixture utilization amount.
  • Fixture utilization works out to 75 % at these inputs, and this is the headline figure for the scenario.
  • Fixture utilization gap works out to -14 points at these inputs.
  • Used fixture utilization amount works out to 360 value at these inputs.
  • Available fixture utilization amount works out to 480 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target fixture utilization sits at 85% and the headline result is 75 %, this scenario lands almost exactly on the baseline at 75 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target fixture utilization, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. High utilization is not automatically good; a fixture pegged near 100% may be starving other jobs or masking that it is the constraint, so read it with throughput in mind.

Results at a glance

  • Fixture utilization: 75 % (headline result)
