Maintenance & Reliability worked example

Asset Replacement Payback with replacement project cost of 325,000 $: a worked example in maintenance & reliability

This worked example runs the asset replacement payback numbers for a tougher week than the baseline: replacement project cost of 325,000 $ instead of the typical 650,000 $. Estimate simple payback for replacing aging equipment using avoided maintenance and downtime savings minus new support cost.

The inputs for this scenario

  • Replacement project cost: 325,000 $ (the input this scenario stresses; the baseline uses 650,000)
  • Annual avoided maintenance and downtime cost: 240,000 $ / yr (held at the documented default)
  • Annual support cost for new asset: 40,000 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net annual savings = annual avoided maintenance and downtime cost - annual support cost for new asset.
  • Replacement Payback Period works out to 1.63 yr at these inputs, and this is the headline figure for the scenario.
  • Net Annual Savings works out to 200,000 $ / yr at these inputs.
  • Replacement Investment works out to 325,000 $ at these inputs.
  • Five-Year Net Benefit works out to 675,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where replacement project cost sits at 650,000 $ and the headline result is 3.25 yr, this scenario comes in 50% below the baseline at 1.63 yr.
  • Use it when an aging machine's maintenance and downtime costs are climbing and you need to justify a replacement against continued repair. 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.
