Seal Kit Cost at 110% installed base share being serviced: a worked example

This scenario runs the seal kit cost calculation on the strong side: 110% installed base share being serviced, with every other input held at its documented default. Use this when budgeting a planned valve maintenance turnaround, comparing seal kit suppliers, or forecasting spare parts spend for quarterly or annual budgets.

The inputs for this scenario

  • Seal kits required for the campaign: 120 kits (unchanged)
  • Average cost per seal kit: 85 $ / kit (unchanged)
  • Installed base share being serviced: 110 % (raised for this scenario; the documented default is 100)
  • Fixed procurement and freight charges: 1,200 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable seal kit cost = kits required x cost per kit x installed base share) to the inputs above produces each figure below.
  • At this operating point the engine returns 12,420 $ for total seal kit cost, the number this scenario is built around.
  • At this operating point the engine returns 104 $ / piece for effective cost per kit (with overhead).
  • At this operating point the engine returns 11,220 $ for variable seal kit cost (all kits).
  • At this operating point the engine returns 1,200 $ for fixed procurement and freight charges.

How this compares with the baseline

  • Against the tool's baseline example, where installed base share being serviced sits at 100% and the headline result is 11,400 $, this scenario comes in 8.95% above the baseline at 12,420 $.
  • Use it when planning a turnaround seal campaign, quoting an aftermarket rebuild contract, or comparing rebuild cost against full valve replacement. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total seal kit cost: 12,420 $ (headline result)
  • Effective cost per kit (with overhead): 104 $ / piece
  • Variable seal kit cost (all kits): 11,220 $
  • Fixed procurement and freight charges: 1,200 $
