PM Optimization Savings at 61% optimized pm tasks expected to stay reliability-compliant: a worked example

This worked example runs the pm optimization savings numbers for a tougher week than the baseline: 61% optimized pm tasks expected to stay reliability-compliant instead of the typical 85%. Estimate savings from optimizing preventive maintenance intervals, routes, and task lists across selected assets.

The inputs for this scenario

  • Preventive-maintenance labor hours eliminated per year: 1,450 labor hr / yr (held at the documented default)
  • Fully loaded maintenance technician labor rate: 82 $ / hr (held at the documented default)
  • Optimized PM tasks expected to stay reliability-compliant: 61 % (the input this scenario stresses; the baseline uses 85)
  • Fixed savings from avoided parts, downtime, and contractor work: 24,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable PM optimization savings = PM labor hours removed or avoided × loaded maintenance labor rate × optimized PM tasks expected to remain compliant.
  • Total PM optimization savings works out to 96,529 $ at these inputs, and this is the headline figure for the scenario.
  • loaded maintenance labor rate works out to 66.57 $ / piece at these inputs.
  • Variable PM optimization savings works out to 72,529 $ at these inputs.
  • fixed savings from avoided parts, downtime, or contractor work works out to 24,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where optimized pm tasks expected to stay reliability-compliant sits at 85% and the headline result is 125,065 $, this scenario comes in 22.82% below the baseline at 96,529 $.
  • Use it when justifying a PM optimization, RCM, or maintenance task analysis project to finance or plant leadership. 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

  • Total PM optimization savings: 96,529 $ (headline result)
  • loaded maintenance labor rate: 66.57 $ / piece
  • Variable PM optimization savings: 72,529 $
  • fixed savings from avoided parts, downtime, or contractor work: 24,000 $
