Spare Parts Kit Cost at 72% kit inclusion share: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop kit inclusion share to 72%, then walk the calculation through step by step. Estimate spare parts kit cost from kit count, parts cost per kit, inclusion share, and fixed kitting or documentation cost.

The inputs for this scenario

  • Spare parts kit count: 12 kits (held at the documented default)
  • Parts cost per kit: 6,400 $ / kit (held at the documented default)
  • Kit inclusion share: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed kitting and documentation cost: 3,800 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable spare parts kit cost = spare parts kit count × parts cost per kit × kit inclusion share.
  • Total spare parts kit cost works out to 59,096 $ at these inputs, and this is the headline figure for the scenario.
  • Parts cost per kit works out to 4,925 $ / kit at these inputs.
  • Variable spare parts kit cost works out to 55,296 $ at these inputs.
  • Fixed kitting and documentation cost works out to 3,800 $ at these inputs.

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 26.68% below the baseline at 59,096 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to kit inclusion share, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses one blended parts cost per kit; a package mixing cheap consumables and expensive critical spares needs that average chosen carefully.

Results at a glance

  • Total spare parts kit cost: 59,096 $ (headline result)
  • Parts cost per kit: 4,925 $ / kit
  • Variable spare parts kit cost: 55,296 $
  • Fixed kitting and documentation cost: 3,800 $
