Maintenance & Reliability worked example

Emergency Repair Cost with number of emergency repair jobs of 0.5 repair: a worked example

This worked example runs the emergency repair cost numbers for a tougher week than the baseline: number of emergency repair jobs of 0.5 repair instead of the typical 1 repair. Estimate the premium cost of emergency repair work compared with a standard planned repair baseline.

The inputs for this scenario

  • Number of emergency repair jobs: 0.5 repair (the input this scenario stresses; the baseline uses 1)
  • Standard planned repair cost baseline: 12,000 $ / repair (held at the documented default)
  • Overtime and after-hours callout premium: 3,800 $ (held at the documented default)
  • Expedited parts and freight surcharge: 2,200 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base emergency repair cost = emergency job basis × standard repair cost baseline.
  • Emergency Repair Cost works out to 12,000 $ / repair at these inputs, and this is the headline figure for the scenario.
  • Cost per Emergency Job works out to 24,000 $ / repair at these inputs.
  • Standard Repair Baseline works out to 6,000 $ at these inputs.
  • Emergency Premium works out to 6,000 $ at these inputs.

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 33.33% below the baseline at 12,000 $ / repair.
  • Use it right after a breakdown to cost the event, or in aggregate to compare reactive versus planned maintenance spend across a year. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Emergency Repair Cost: 12,000 $ / repair (headline result)
  • Cost per Emergency Job: 24,000 $ / repair
  • Standard Repair Baseline: 6,000 $
  • Emergency Premium: 6,000 $
