Cartridge Replacement Cost at 72% share of cartridge bank being changed: a worked example

This worked example runs the cartridge replacement cost numbers for a tougher week than the baseline: 72% share of cartridge bank being changed instead of the typical 100%. Estimate cartridge replacement cost from cartridge count, cartridge price, replacement scope, and fixed labor or disposal charges.

The inputs for this scenario

  • Cartridges to replace: 96 cartridges (held at the documented default)
  • Cost per cartridge: 82 $ / cartridge (held at the documented default)
  • Share of cartridge bank being changed: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed labor and disposal cost: 1,800 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable cartridge replacement cost = cartridges to replace × cost per cartridge × replacement scope included.
  • Total cartridge replacement cost works out to 7,468 $ at these inputs, and this is the headline figure for the scenario.
  • Cost per cartridge works out to 77.79 $ / cartridge at these inputs.
  • Variable cartridge replacement cost works out to 5,668 $ at these inputs.
  • Fixed labor and disposal cost works out to 1,800 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of cartridge bank being changed sits at 100% and the headline result is 9,672 $, this scenario comes in 22.79% below the baseline at 7,468 $.
  • Use it when scheduling a filter change on differential-pressure trigger, quoting a service call, or comparing full versus partial bank replacement. 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

  • Total cartridge replacement cost: 7,468 $ (headline result)
  • Cost per cartridge: 77.79 $ / cartridge
  • Variable cartridge replacement cost: 5,668 $
  • Fixed labor and disposal cost: 1,800 $
