Furnace Maintenance Cost at 110% maintenance cost capture: a worked example

What does the result look like when maintenance cost capture reaches 110%? The full calculation is worked below with real intermediate numbers. Use it when heating elements, burners, fans, belts, insulation, seals, pumps, thermocouples, or controls maintenance needs cost visibility.

The inputs for this scenario

  • Maintenance labor hours: 24 hr (unchanged)
  • Loaded maintenance rate: 95 $ / hr (unchanged)
  • Maintenance cost capture: 110 % (raised for this scenario; the documented default is 100)
  • Fixed parts or service cost: 1,800 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Captured furnace maintenance cost = maintenance hours × loaded maintenance rate × maintenance cost capture) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,308 $ for total furnace maintenance cost, the number this scenario is built around.
  • At this operating point the engine returns 180 $ / hr for maintenance cost per hour.
  • At this operating point the engine returns 2,508 $ for captured labor cost.
  • At this operating point the engine returns 1,800 $ for fixed parts or service cost.

How this compares with the baseline

  • Against the tool's baseline example, where maintenance cost capture sits at 100% and the headline result is 4,080 $, this scenario comes in 5.59% above the baseline at 4,308 $.
  • A figure at this level is achievable when maintenance cost capture is genuinely sustained, not just peaked for a shift. It costs a single event; it does not annualize PM frequency or fold in the downtime/lost-production cost of the furnace being offline.
