GMP Cleanroom Utilization Cost at 61% suite time assigned to this product or campaign: a worked example

This worked example runs the gmp cleanroom utilization cost numbers for a tougher week than the baseline: 61% suite time assigned to this product or campaign instead of the typical 85%. Estimate the cost of occupied GMP cleanroom suite hours for cell therapy or gene therapy production.

The inputs for this scenario

  • Occupied GMP cleanroom suite time: 240 suite hr (held at the documented default)
  • Fully burdened cleanroom cost: 650 $ / suite hr (held at the documented default)
  • Suite time assigned to this product or campaign: 61 % (the input this scenario stresses; the baseline uses 85)
  • Fixed gowning, clearance, or EM charge: 12,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable cleanroom suite cost = occupied GMP suite time × fully burdened cleanroom cost × assigned share.
  • Allocated cleanroom utilization cost works out to 107,160 $ / period at these inputs, and this is the headline figure for the scenario.
  • Cleanroom cost per occupied suite hour works out to 447 $ / suite hr at these inputs.
  • Variable cleanroom suite cost works out to 95,160 $ at these inputs.
  • Fixed cleanroom support charge works out to 12,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where suite time assigned to this product or campaign sits at 85% and the headline result is 144,600 $ / period, this scenario comes in 25.89% below the baseline at 107,160 $ / period.
  • Use it when building cost-of-goods, quoting a CDMO campaign, or allocating a shared suite across multiple products or runs. 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

  • Allocated cleanroom utilization cost: 107,160 $ / period (headline result)
  • Cleanroom cost per occupied suite hour: 447 $ / suite hr
  • Variable cleanroom suite cost: 95,160 $
  • Fixed cleanroom support charge: 12,000 $
