Field Service Cost at 72% covered service scope: a worked example

This worked example runs the field service cost numbers for a tougher week than the baseline: 72% covered service scope instead of the typical 100%. Estimate annual or project field service cost for industrial heat pump systems from visit count, loaded visit cost, covered scope, and fixed mobilization or support cost.

The inputs for this scenario

  • Planned or corrective service visits: 12 visits (held at the documented default)
  • Average cost per service visit: 1,800 $ / visit (held at the documented default)
  • Covered service scope: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed mobilization and support cost: 3,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable field service cost = planned or corrective service visits × average cost per service visit × covered service scope.
  • Total field service cost works out to 19,052 $ at these inputs, and this is the headline figure for the scenario.
  • Average cost per service visit works out to 1,588 $ / visit at these inputs.
  • Variable field service cost works out to 15,552 $ at these inputs.
  • Fixed mobilization and support cost works out to 3,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where covered service scope sits at 100% and the headline result is 25,100 $, this scenario comes in 24.1% below the baseline at 19,052 $.
  • Use it to price a service agreement or forecast annual O&M for a heat pump or thermal plant. 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 field service cost: 19,052 $ (headline result)
  • Average cost per service visit: 1,588 $ / visit
  • Variable field service cost: 15,552 $
  • Fixed mobilization and support cost: 3,500 $
