Emergency Repair Cost with number of emergency repair jobs of 2.5 repair: a worked example

What does the result look like when number of emergency repair jobs reaches 2.5 repair? The full calculation is worked below with real intermediate numbers. Use it when showing the financial penalty of after-hours callouts, overtime, and expedited parts.

The inputs for this scenario

  • Number of emergency repair jobs: 2.5 repair (raised for this scenario; the documented default is 1)
  • Standard planned repair cost baseline: 12,000 $ / repair (unchanged)
  • Overtime and after-hours callout premium: 3,800 $ (unchanged)
  • Expedited parts and freight surcharge: 2,200 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Base emergency repair cost = emergency job basis × standard repair cost baseline) to the inputs above produces each figure below.
  • At this operating point the engine returns 36,000 $ / repair for emergency repair cost, the number this scenario is built around.
  • At this operating point the engine returns 14,400 $ / repair for cost per emergency job.
  • At this operating point the engine returns 30,000 $ for standard repair baseline.
  • At this operating point the engine returns 6,000 $ for emergency premium.

How this compares with the baseline

  • Against the tool's baseline example, where number of emergency repair jobs sits at 1 repair and the headline result is 18,000 $ / repair, this scenario comes in 100% above the baseline at 36,000 $ / repair.
  • A figure at this level is achievable when number of emergency repair jobs is genuinely sustained, not just peaked for a shift. It captures direct repair costs only; it does not include lost production, scrap, expedited-shipping penalties to your own customers, or safety and quality fallout, which often exceed the repair cost itself.
