Coating Cost per Pump at 72% share receiving full coating system: a worked example

Suppose share receiving full coating system falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate coating cost per pump for water and wastewater systems from run size, per-pump coating cost, the share needing the full system, and fixed booth adders.

The inputs for this scenario

  • Pumps to coat: 60 pumps (held at the documented default)
  • Coating cost per pump: 140 $ / pump (held at the documented default)
  • Share receiving full coating system: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed booth and prep cost: 1,200 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total coating cost = pumps to coat x coating cost per pump x share receiving full coating system + fixed booth and prep cost.
  • Total coating cost per pump cost works out to 7,248 $ at these inputs, and this is the headline figure for the scenario.
  • Coating cost per pump cost per unit works out to 121 $ / piece at these inputs.
  • Variable coating cost per pump cost works out to 6,048 $ at these inputs.
  • Fixed coating cost per pump adder works out to 1,200 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share receiving full coating system sits at 100% and the headline result is 9,600 $, this scenario comes in 24.5% below the baseline at 7,248 $.
  • It computes total coating cost as quantity times per-pump cost times the full-system share, plus fixed booth and prep, then divides to a per-pump figure. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
