IGU Gas Fill Cost at 72% share of fills charged to this run: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop share of fills charged to this run to 72%, then walk the calculation through step by step. Estimate argon or krypton gas fill cost from filled IGU count, gas cost per unit, scope, and fixed setup adders.

The inputs for this scenario

  • Insulating glass units gas-filled: 155 IGUs (held at the documented default)
  • Argon/krypton fill cost per IGU: 7.8 $ / IGU (held at the documented default)
  • Share of fills charged to this run: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed gas line setup and fill-rate verification adder: 240 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable IGU gas fill cost = gas-filled IGUs × gas fill cost per IGU × gas fill scope included.
  • total IGU gas fill cost works out to 1,110 $ at these inputs, and this is the headline figure for the scenario.
  • gas fill cost per IGU works out to 7.16 $ / piece at these inputs.
  • variable gas fill cost works out to 870 $ at these inputs.
  • fixed gas setup and verification adder works out to 240 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of fills charged to this run sits at 100% and the headline result is 1,449 $, this scenario comes in 23.36% below the baseline at 1,110 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to share of fills charged to this run, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single average cost per IGU; krypton-filled and triple-pane units cost far more per fill than standard argon double-panes and should be modeled separately.

Results at a glance

  • total IGU gas fill cost: 1,110 $ (headline result)
  • gas fill cost per IGU: 7.16 $ / piece
  • variable gas fill cost: 870 $
  • fixed gas setup and verification adder: 240 $
