Depot Repair Yield Calculator

Depot repair yield shows how many returned units are successfully repaired, tested, and returned to stock or customers. It helps service centers find process, parts, test, or diagnostic issues that drive rework and turnaround delays.

What this calculator does

  • Calculate accepted depot repair yield from repaired units passing final test, total repair attempts, and the yield target.
  • a depot repair manager needs to measure successful repair output from the repair queue
  • Returns the percentage of repair attempts that produce accepted repaired units.

Formula used

  • Depot repair yield = repaired units passing final test ÷ depot repair attempts × 100
  • Repair yield gap = depot repair yield - target repair yield

Inputs explained

  • Repaired units passing final test: undefined
  • Depot repair attempts: undefined
  • Target depot repair yield: undefined

How to use the result

  • Use it for depot productivity, exchange stock readiness, technician training, test process improvement, and repair parts planning.
  • Separate no-fault-found, beyond-economic-repair, missing parts, test equipment failures, and repeat failures for root-cause action.

Common questions

  • What information do I need for depot repair yield? You need accepted repaired unit count, total repair attempt count, and the target repair yield.
  • Which units or time period should I use for depot repair yield? Use the units shown next to each input and keep all counts, costs, service calls, installed-base records, and labor hours in the same planning period. Convert mixed periods such as weeks, months, quarters, or years before entering the values.
  • What does the depot repair yield result tell me? It shows whether depot repair activity is producing accepted units at the expected rate.
  • When is this depot repair yield estimate only approximate? Use it to improve diagnostics, add repair training, stock repair parts, change test procedures, or shift units to replacement policy.
