Aftermarket Revenue per Installed Unit at 46% revenue capture share: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop revenue capture share to 46%, then walk the calculation through step by step. Estimate aftermarket revenue from installed units, revenue per unit, attach or capture share, and fixed revenue adjustment.

The inputs for this scenario

  • Active installed units: 4,200 units (held at the documented default)
  • Aftermarket revenue per unit: 390 $ / unit (held at the documented default)
  • Revenue capture share: 46 % (the input this scenario stresses; the baseline uses 64)
  • Fixed aftermarket revenue adjustment: 25,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Captured aftermarket revenue = active installed units × revenue per unit × revenue capture share.
  • Aftermarket revenue estimate works out to 778,480 $ aftermarket revenue at these inputs, and this is the headline figure for the scenario.
  • Aftermarket revenue per unit works out to 185 $ / unit at these inputs.
  • Captured aftermarket revenue works out to 753,480 $ aftermarket revenue at these inputs.
  • Fixed aftermarket revenue adjustment works out to 25,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where revenue capture share sits at 64% and the headline result is 1,073,320 $ aftermarket revenue, this scenario comes in 27.47% below the baseline at 778,480 $ aftermarket revenue.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to revenue capture share, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single average revenue-per-unit and capture rate; a fleet spanning new and end-of-life units will spend very differently, so a blended figure can mislead on either end.
