Maintenance & Reliability worked example

Maintenance ROI with maintenance savings of 450,000 $: a worked example

What does the result look like when maintenance savings reaches 450,000 $? The full calculation is worked below with real intermediate numbers. Use it when justifying predictive maintenance, redesign work, or shutdown scope based on avoided loss and maintenance savings.

The inputs for this scenario

  • Maintenance savings: 450,000 $ (raised for this scenario; the documented default is 180,000)
  • Maintenance investment: 60,000 $ (unchanged)
  • ROI reference basis: 60,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Net maintenance gain = maintenance savings - maintenance investment) to the inputs above produces each figure below.
  • At this operating point the engine returns 650 % for maintenance roi, the number this scenario is built around.
  • At this operating point the engine returns 390,000 $ for net maintenance gain.
  • At this operating point the engine returns 450,000 $ for maintenance savings.
  • At this operating point the engine returns 60,000 $ for maintenance investment.

How this compares with the baseline

  • Against the tool's baseline example, where maintenance savings sits at 180,000 $ and the headline result is 200 %, this scenario comes in 225% above the baseline at 650 %.
  • A figure at this level is achievable when maintenance savings is genuinely sustained, not just peaked for a shift. Savings from avoided failures are estimates, not invoiced amounts, so the ROI is only as defensible as your downtime and failure-cost data.
