Tooling Storage Cost at 72% occupancy share: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop occupancy share to 72%, then walk the calculation through step by step. Estimate the cost of warehousing idle tooling, combining a monthly slot charge with one-time preservation and handling fees.

The inputs for this scenario

  • Storage Duration: 24 months (held at the documented default)
  • Monthly Slot Rate: 45 $/month (held at the documented default)
  • Occupancy Share: 72 % (the input this scenario stresses; the baseline uses 100)
  • Preservation & Handling Fee: 300 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Storage cost = months x monthly slot rate x occupancy share% + preservation fee.
  • Total tooling storage cost works out to 1,078 $ at these inputs, and this is the headline figure for the scenario.
  • Tooling storage cost per unit works out to 44.9 $ / piece at these inputs.
  • Variable tooling storage cost works out to 778 $ at these inputs.
  • Fixed tooling storage cost adder works out to 300 $ at these inputs.

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 21.91% below the baseline at 1,078 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to occupancy share, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It does not price the risk of tool degradation or obsolescence, nor the opportunity cost of the floor and rack space beyond the quoted slot rate.
