Agent Fill Cost at 72% chargeable agent-cost share: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop chargeable agent-cost share to 72%, then walk the calculation through step by step. Estimate suppression-agent fill cost from agent quantity, cost per unit, chargeable share, and fixed fill setup cost.

The inputs for this scenario

  • Suppression agent charged: 850 lb, kg, gal, or L (held at the documented default)
  • Agent price per unit: 22 $ / unit (held at the documented default)
  • Chargeable agent-cost share: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed fill setup and handling cost: 275 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Agent Fill Cost = suppression agent quantity × agent cost per unit × chargeable agent-cost share + fixed fill setup or handling cost.
  • Total agent fill cost works out to 13,739 $ at these inputs, and this is the headline figure for the scenario.
  • Average agent fill cost per unit works out to 16.16 $ / unit at these inputs.
  • Variable captured cost works out to 13,464 $ at these inputs.
  • Fixed fill setup or handling cost works out to 275 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where chargeable agent-cost share sits at 100% and the headline result is 18,975 $, this scenario comes in 27.59% below the baseline at 13,739 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to chargeable agent-cost share, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It models a single agent fill at one price point — it does not account for agent reclaim credits, scrap/boil-off loss, multi-agent blends, or vessel/valve hardware cost, which you add separately.
