Asset Lifecycle Cost at 72% lifecycle years or scope share included: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop lifecycle years or scope share included to 72%, then walk the calculation through step by step. Estimate asset lifecycle cost across owned assets using annualized cost per asset, included life-cycle scope, and fixed replacement or disposal costs.

The inputs for this scenario

  • Assets in the lifecycle model: 34 assets (held at the documented default)
  • Annualized lifecycle cost per asset: 56,000 $ / asset-yr (held at the documented default)
  • Lifecycle years or scope share included: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed overhaul, replacement, or disposal cost: 480,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable asset lifecycle cost = asset count in lifecycle model × annualized lifecycle cost per asset × lifecycle years or scope included.
  • Total asset lifecycle cost works out to 1,850,880 $ at these inputs, and this is the headline figure for the scenario.
  • annualized lifecycle cost per asset works out to 54,438 $ / piece at these inputs.
  • Variable asset lifecycle cost works out to 1,370,880 $ at these inputs.
  • fixed overhaul, replacement, or disposal cost works out to 480,000 $ at these inputs.

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 22.36% below the baseline at 1,850,880 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to lifecycle years or scope share included, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. 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: 1,850,880 $ (headline result)
  • annualized lifecycle cost per asset: 54,438 $ / piece
  • Variable asset lifecycle cost: 1,370,880 $
  • fixed overhaul, replacement, or disposal cost: 480,000 $
