Maintenance & Reliability worked example

Maintenance ROI with maintenance savings of 90,000 $: a worked example

Suppose maintenance savings falls to 90,000 $. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate return on maintenance investment by comparing maintenance savings against maintenance cost.

The inputs for this scenario

  • Maintenance savings: 90,000 $ (the input this scenario stresses; the baseline uses 180,000)
  • Maintenance investment: 60,000 $ (held at the documented default)
  • ROI reference basis: 60,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net maintenance gain = maintenance savings - maintenance investment.
  • Maintenance ROI works out to 50 % at these inputs, and this is the headline figure for the scenario.
  • Net Maintenance Gain works out to 30,000 $ at these inputs.
  • Maintenance Savings works out to 90,000 $ at these inputs.
  • Maintenance Investment works out to 60,000 $ at these inputs.

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 75% below the baseline at 50 %.
  • It computes maintenance ROI as a percentage by dividing net maintenance gain (savings minus investment) by a chosen reference basis. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
