Aftermarket Revenue per Installed Unit at 74% revenue capture share: a worked example

What does the result look like when revenue capture share reaches 74%? The full calculation is worked below with real intermediate numbers. an aftermarket sales manager needs to estimate revenue potential from the active installed base

The inputs for this scenario

  • Active installed units: 4,200 units (unchanged)
  • Aftermarket revenue per unit: 390 $ / unit (unchanged)
  • Revenue capture share: 74 % (raised for this scenario; the documented default is 64)
  • Fixed aftermarket revenue adjustment: 25,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Captured aftermarket revenue = active installed units × revenue per unit × revenue capture share) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,237,120 $ aftermarket revenue for aftermarket revenue estimate, the number this scenario is built around.
  • At this operating point the engine returns 295 $ / unit for aftermarket revenue per unit.
  • At this operating point the engine returns 1,212,120 $ aftermarket revenue for captured aftermarket revenue.
  • At this operating point the engine returns 25,000 $ for fixed aftermarket revenue adjustment.

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 15.26% above the baseline at 1,237,120 $ aftermarket revenue.
  • A figure at this level is achievable when revenue capture share is genuinely sustained, not just peaked for a shift. 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.
