Maintenance Cost per Asset at 110% asset population included in budget scope: a worked example

What does the result look like when asset population included in budget scope reaches 110%? The full calculation is worked below with real intermediate numbers. a maintenance or asset-management team needs to benchmark maintenance spend, compare asset classes, and support budget or replacement discussions for a asset maintenance budget

The inputs for this scenario

  • maintained asset count: 540 assets (unchanged)
  • maintenance cost per asset: 4,200 $ / asset (unchanged)
  • asset population included in budget scope: 110 % (raised for this scenario; the documented default is 100)
  • fixed maintenance program cost: 185,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable maintenance cost per asset = maintained asset count × maintenance cost per asset × asset population included in budget scope) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,679,800 $ for total maintenance cost per asset, the number this scenario is built around.
  • At this operating point the engine returns 4,963 $ / piece for maintenance cost per asset.
  • At this operating point the engine returns 2,494,800 $ for variable maintenance cost per asset.
  • At this operating point the engine returns 185,000 $ for fixed maintenance program cost.

How this compares with the baseline

  • Against the tool's baseline example, where asset population included in budget scope sits at 100% and the headline result is 2,453,000 $, this scenario comes in 9.25% above the baseline at 2,679,800 $.
  • A figure at this level is achievable when asset population included in budget scope is genuinely sustained, not just peaked for a shift. It applies a single average per-asset cost; real fleets have wide cost dispersion, so a handful of bad actors can be hidden inside the average.

  • Total maintenance cost per asset: 2,679,800 $ (headline result)
  • maintenance cost per asset: 4,963 $ / piece
  • Variable maintenance cost per asset: 2,494,800 $
  • fixed maintenance program cost: 185,000 $
