Electronics Repair, Refurbishment & Depot Operations calculator

No-Fault-Found Rate Calculator

Measure the share of returned electronics that pass diagnostics with no confirmed defect, helping quantify avoidable RMA volume and customer support burden. Two counts and a target give you a rate plus how far you are from where you need to be.

What this calculator does

  • Measure the share of returned electronics that pass diagnostics with no confirmed defect, helping quantify avoidable RMA volume and customer support burden.
  • Use it when no-fault-found rate in electronics repair, refurbishment and depot operations needs a clean rate and gap-to-target you can put on a tier board.
  • Turns no-fault-found rma units, total diagnosed rma units, target no-fault-found rate into a rate for no-fault-found rate in electronics repair, refurbishment and depot operations.

Formula used

  • No-fault-found rate = no-fault-found RMA units ÷ total diagnosed RMA units × 100
  • No-fault-found gap to target = no-fault-found rate - target no-fault-found rate

Inputs explained

  • No-fault-found RMA units: undefined
  • Total diagnosed RMA units: undefined
  • Target no-fault-found rate: undefined

How to use the result

  • Use it when no-fault-found rate in electronics repair, refurbishment and depot operations is being reviewed against a KPI.
  • Trend matters more than a single snapshot; pull the result for the last several periods before you act.

Common questions

  • How does this no-fault-found rate calculator help my electronics repair, refurbishment and depot operations team? Measure the share of returned electronics that pass diagnostics with no confirmed defect, helping quantify avoidable RMA volume and customer support burden. You get a rate you can defend before quoting, scheduling, or sign-off.
  • Where do I get the inputs for this electronics repair, refurbishment and depot operations calculator? no-fault-found rma units, total diagnosed rma units, target no-fault-found rate usually move the rate most. Pull from measured electronics repair, refurbishment and depot operations runs, supplier data, and recent quotes rather than memory.
  • How should I use the result? Use the gap to target to prioritize the next electronics repair, refurbishment and depot operations kaizen or corrective action.
  • What can throw the result off? Confirm the counts came from the same time window and the same scope; mismatched scope is the most common error.
