Depot Repair Cost at 63% chargeable repair cost share: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop chargeable repair cost share to 63%, then walk the calculation through step by step. Estimate depot repair cost from repair orders, average repair cost, chargeable share, and fixed depot overhead.

The inputs for this scenario

  • Depot repair orders: 96 orders (held at the documented default)
  • Average depot repair cost: 740 $ / order (held at the documented default)
  • Chargeable repair cost share: 63 % (the input this scenario stresses; the baseline uses 87)
  • Fixed depot overhead: 11,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Chargeable depot repair cost = repair orders × average repair cost × chargeable share.
  • Depot repair cost works out to 56,255 $ depot repair cost at these inputs, and this is the headline figure for the scenario.
  • Average depot repair cost works out to 586 $ / order at these inputs.
  • Chargeable depot repair cost works out to 44,755 $ depot repair cost at these inputs.
  • Fixed depot overhead works out to 11,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where chargeable repair cost share sits at 87% and the headline result is 73,305 $ depot repair cost, this scenario comes in 23.26% below the baseline at 56,255 $ depot repair cost.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to chargeable repair cost share, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single blended average cost per order, so a depot handling very different repair complexities will need to segment by product or repair tier for accurate quoting.
