Spare Parts Kit Cost at 110% kit inclusion share: a worked example

This scenario runs the spare parts kit cost calculation on the strong side: 110% kit inclusion share, with every other input held at its documented default. Use it when quoting commissioning kits, warranty kits, recommended spares, maintenance kits, or startup spare parts packages.

The inputs for this scenario

  • Spare parts kit count: 12 kits (unchanged)
  • Parts cost per kit: 6,400 $ / kit (unchanged)
  • Kit inclusion share: 110 % (raised for this scenario; the documented default is 100)
  • Fixed kitting and documentation cost: 3,800 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable spare parts kit cost = spare parts kit count × parts cost per kit × kit inclusion share) to the inputs above produces each figure below.
  • At this operating point the engine returns 88,280 $ for total spare parts kit cost, the number this scenario is built around.
  • At this operating point the engine returns 7,357 $ / kit for parts cost per kit.
  • At this operating point the engine returns 84,480 $ for variable spare parts kit cost.
  • At this operating point the engine returns 3,800 $ for fixed kitting and documentation cost.

How this compares with the baseline

  • Against the tool's baseline example, where kit inclusion share sits at 100% and the headline result is 80,600 $, this scenario comes in 9.53% above the baseline at 88,280 $.
  • Use it when quoting a recommended-spares package, planning aftermarket revenue, or budgeting customer inventory for a machine. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
