Asset Lifecycle Cost at 110% lifecycle years or scope share included: a worked example

What does the result look like when lifecycle years or scope share included reaches 110%? The full calculation is worked below with real intermediate numbers. a maintenance or asset-management team needs to compare lifecycle cost, replacement timing, maintenance strategy, and capital planning options for a asset lifecycle plan

The inputs for this scenario

  • Assets in the lifecycle model: 34 assets (unchanged)
  • Annualized lifecycle cost per asset: 56,000 $ / asset-yr (unchanged)
  • Lifecycle years or scope share included: 110 % (raised for this scenario; the documented default is 100)
  • Fixed overhaul, replacement, or disposal cost: 480,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable asset lifecycle cost = asset count in lifecycle model × annualized lifecycle cost per asset × lifecycle years or scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,574,400 $ for total asset lifecycle cost, the number this scenario is built around.
  • At this operating point the engine returns 75,718 $ / piece for annualized lifecycle cost per asset.
  • At this operating point the engine returns 2,094,400 $ for variable asset lifecycle cost.
  • At this operating point the engine returns 480,000 $ for fixed overhaul, replacement, or disposal cost.

How this compares with the baseline

  • Against the tool's baseline example, where lifecycle years or scope share included sits at 100% and the headline result is 2,384,000 $, this scenario comes in 7.99% above the baseline at 2,574,400 $.
  • A figure at this level is achievable when lifecycle years or scope share included is genuinely sustained, not just peaked for a shift. It uses undiscounted nominal dollars, so for long horizons or formal capital approval you should run a net-present-value version alongside it.

Results at a glance

  • Total asset lifecycle cost: 2,574,400 $ (headline result)
  • annualized lifecycle cost per asset: 75,718 $ / piece
  • Variable asset lifecycle cost: 2,094,400 $
  • fixed overhaul, replacement, or disposal cost: 480,000 $
