Electronics Repair, Refurbishment & Depot Operations worked example

Cost Per Repaired Unit at 92% repair scope included: a worked example

What does the result look like when repair scope included reaches 92%? The full calculation is worked below with real intermediate numbers. Use it when cost per repaired unit in electronics repair, refurbishment and depot operations is being put through a electronics repair, refurbishment and depot operations weighted-cost review.

The inputs for this scenario

  • Repaired units in estimate: 100 units (unchanged)
  • Variable cost per repaired unit: 45 $ / unit (unchanged)
  • Repair scope included: 92 % (raised for this scenario; the documented default is 80)
  • Fixed depot support cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable repair cost = repaired units in estimate × variable cost per repaired unit × repair scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total repaired-unit cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for cost per repaired unit.
  • At this operating point the engine returns 4,140 $ for variable repair cost.
  • At this operating point the engine returns 250 $ for fixed depot support cost.

How this compares with the baseline

  • Against the tool's baseline example, where repair scope included sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • A figure at this level is achievable when repair scope included is genuinely sustained, not just peaked for a shift. The model averages fixed cost evenly across all estimated units, so it understates per-unit cost on short runs and hides the spread between a fast no-fault-found unit and a hard board-level repair.

Results at a glance

  • Total repaired-unit cost: 4,390 $ (headline result)
  • Cost per repaired unit: 43.9 $ / piece
  • Variable repair cost: 4,140 $
