Commercial Pool Operating Cost with daily chemical program cost of 43 $ / day: a worked example

This worked example runs the commercial pool operating cost numbers for a tougher week than the baseline: daily chemical program cost of 43 $ / day instead of the typical 85 $ / day. Estimate daily commercial pool operating cost from chemicals, energy, labor, and fixed overhead.

The inputs for this scenario

  • Daily chemical program cost: 43 $ / day (the input this scenario stresses; the baseline uses 85)
  • Daily energy and water cost: 140 $ / day (held at the documented default)
  • Daily labor and service cost: 220 $ / day (held at the documented default)
  • Daily fixed overhead: 75 $ / day (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Daily operating cost = chemical cost + energy and water cost + labor cost + fixed overhead.
  • Daily operating cost works out to 478 $ / day at these inputs, and this is the headline figure for the scenario.
  • Element 1 works out to 43 $ / day at these inputs.
  • Element 2 works out to 140 $ / day at these inputs.
  • Element 3 + 4 works out to 295 $ / day at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where daily chemical program cost sits at 85 $ / day and the headline result is 520 $ / day, this scenario comes in 8.08% below the baseline at 478 $ / day.
  • Use it to build an operating budget, price memberships or rentals, or compare the daily cost of two facilities. 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

  • Daily operating cost: 478 $ / day (headline result)
  • Element 1: 43 $ / day
  • Element 2: 140 $ / day
  • Element 3 + 4: 295 $ / day
