What does the result look like when asset replacement capital investment reaches 1,625,000 $? The full calculation is worked below with real intermediate numbers. a maintenance or asset-management team needs to screen replacement timing, justify capital requests, or compare repair-versus-replace scenarios for a asset replacement case

The inputs for this scenario

  • Asset replacement capital investment: 1,625,000 $ (raised for this scenario; the documented default is 650,000)
  • Annual maintenance and downtime savings: 185,000 $ / yr (unchanged)
  • Annual support cost for the replacement asset: 42,000 $ / yr (unchanged)

Working through the calculation

  • Applying the documented formula (Net annual asset replacement payback savings = annual maintenance and downtime savings - annual support cost for replacement asset) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.36 yr for asset replacement payback payback period, the number this scenario is built around.
  • At this operating point the engine returns 143,000 $ / yr for net annual asset replacement payback savings.
  • At this operating point the engine returns 1,625,000 $ for asset replacement investment.
  • At this operating point the engine returns -910,000 $ for five-year net asset replacement payback value.

How this compares with the baseline

  • Against the tool's baseline example, where asset replacement capital investment sits at 650,000 $ and the headline result is 4.55 yr, this scenario comes in 150% above the baseline at 11.36 yr.
  • A figure at this level is achievable when asset replacement capital investment is genuinely sustained, not just peaked for a shift. Simple payback ignores the time value of money, salvage value, and savings that change over time — use it to screen projects, then run NPV or IRR for the final capital decision.
