Tooling Storage Cost at 110% occupancy share: a worked example

This scenario runs the tooling storage cost calculation on the strong side: 110% occupancy share, with every other input held at its documented default. A supply chain planner uses it to price the carrying cost of inactive molds and dies held against future service or repeat orders.

The inputs for this scenario

  • Storage Duration: 24 months (unchanged)
  • Monthly Slot Rate: 45 $/month (unchanged)
  • Occupancy Share: 110 % (raised for this scenario; the documented default is 100)
  • Preservation & Handling Fee: 300 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Storage cost = months x monthly slot rate x occupancy share% + preservation fee) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,488 $ for total tooling storage cost, the number this scenario is built around.
  • At this operating point the engine returns 62 $ / piece for tooling storage cost per unit.
  • At this operating point the engine returns 1,188 $ for variable tooling storage cost.
  • At this operating point the engine returns 300 $ for fixed tooling storage cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where occupancy share sits at 100% and the headline result is 1,380 $, this scenario comes in 7.83% above the baseline at 1,488 $.
  • Use it during storage-vs-scrap reviews, customer tooling-ownership audits, or annual inventory carrying-cost analysis. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total tooling storage cost: 1,488 $ (headline result)
  • Tooling storage cost per unit: 62 $ / piece
  • Variable tooling storage cost: 1,188 $
  • Fixed tooling storage cost adder: 300 $
