Optics Manufacturing ROI with total capital investment in optics line of 625,000 $: a worked example

What does the result look like when total capital investment in optics line reaches 625,000 $? The full calculation is worked below with real intermediate numbers. Use this when preparing a capital expenditure request for new optics production equipment, comparing competing investment options, or screening projects before building a full business case.

The inputs for this scenario

  • Total capital investment in optics line: 625,000 $ (raised for this scenario; the documented default is 250,000)
  • Expected annual savings from new line: 95,000 $ / yr (unchanged)
  • Annual support and operating cost: 18,000 $ / yr (unchanged)

Working through the calculation

  • Applying the documented formula (Net annual savings = expected annual savings - annual support cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.12 yr for payback period, the number this scenario is built around.
  • At this operating point the engine returns 77,000 $ / yr for net annual savings.
  • At this operating point the engine returns 625,000 $ for total capital investment.
  • At this operating point the engine returns -240,000 $ for five-year net value.

How this compares with the baseline

  • Against the tool's baseline example, where total capital investment in optics line sits at 250,000 $ and the headline result is 3.25 yr, this scenario comes in 150% above the baseline at 8.12 yr.
  • A figure at this level is achievable when total capital investment in optics line is genuinely sustained, not just peaked for a shift. Simple payback ignores the time value of money, salvage value, ramp-up time and savings that change year over year, so treat it as a screening number, not a full financial model.
