Warehouse Cube at 65% space utilization: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop space utilization to 65%, then walk the calculation through step by step. Estimate warehouse racking throughput for finished gypsum board inventory based on pallets racked, available rack hours, and space utilization.

The inputs for this scenario

  • Pallets racked: 1,200 pallets (held at the documented default)
  • Available rack hours: 8 hr (held at the documented default)
  • Space utilization: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw racking rate = pallets racked / available rack hours.
  • Effective throughput works out to 97.5 pallets / hr at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 150 pallets / hr at these inputs.
  • Efficiency works out to 65 % at these inputs.
  • Runtime works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where space utilization sits at 90% and the headline result is 135 pallets / hr, this scenario comes in 27.78% below the baseline at 97.5 pallets / hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to space utilization, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Space utilization is a blunt single factor; it won't capture a specific congested aisle or a SKU that doesn't stack to full beam height.

Results at a glance

  • Effective throughput: 97.5 pallets / hr (headline result)
  • Raw throughput: 150 pallets / hr
  • Efficiency: 65 %
  • Runtime: 8 hr
