Field Service Cost at 110% covered service scope: a worked example

This scenario runs the field service cost calculation on the strong side: 110% covered service scope, with every other input held at its documented default. Use it when service managers, aftermarket teams, or plant operators need to budget preventive and corrective service for installed heat pump assets.

The inputs for this scenario

  • Planned or corrective service visits: 12 visits (unchanged)
  • Average cost per service visit: 1,800 $ / visit (unchanged)
  • Covered service scope: 110 % (raised for this scenario; the documented default is 100)
  • Fixed mobilization and support cost: 3,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable field service cost = planned or corrective service visits × average cost per service visit × covered service scope) to the inputs above produces each figure below.
  • At this operating point the engine returns 27,260 $ for total field service cost, the number this scenario is built around.
  • At this operating point the engine returns 2,272 $ / visit for average cost per service visit.
  • At this operating point the engine returns 23,760 $ for variable field service cost.
  • At this operating point the engine returns 3,500 $ for fixed mobilization and support cost.

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 8.61% above the baseline at 27,260 $.
  • Use it to price a service agreement or forecast annual O&M for a heat pump or thermal plant. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total field service cost: 27,260 $ (headline result)
