Corrective Maintenance Cost with repair event basis of 2.5 repair: a worked example

This scenario runs the corrective maintenance cost calculation on the strong side: repair event basis of 2.5 repair, with every other input held at its documented default. Use it when comparing corrective versus preventive work or when chronic failures need a true repair cost baseline.

The inputs for this scenario

  • Repair event basis: 2.5 repair (raised for this scenario; the documented default is 1)
  • Repair parts and labor cost: 9,200 $ / repair (unchanged)
  • Downtime production loss: 18,000 $ (unchanged)
  • Expediting and cleanup cost: 2,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Base corrective repair cost = repair event basis × repair parts and labor cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 43,500 $ / repair for corrective maintenance cost, the number this scenario is built around.
  • At this operating point the engine returns 17,400 $ / repair for cost per repair basis.
  • At this operating point the engine returns 23,000 $ for repair parts and labor.
  • At this operating point the engine returns 20,500 $ for downtime and expediting.

How this compares with the baseline

  • Against the tool's baseline example, where repair event basis sits at 1 repair and the headline result is 29,700 $ / repair, this scenario comes in 46.46% above the baseline at 43,500 $ / repair.
  • Use it after an unplanned failure, or when building a business case to show how much a single run-to-failure event really costs versus preventing it. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Corrective Maintenance Cost: 43,500 $ / repair (headline result)
  • Cost per Repair Basis: 17,400 $ / repair
  • Repair Parts and Labor: 23,000 $
  • Downtime and Expediting: 20,500 $
