Optics Manufacturing ROI with total capital investment in optics line of 125,000 $: a worked example

Suppose total capital investment in optics line falls to 125,000 $. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate simple payback period for an optics manufacturing capital investment (new polishing machine, coating chamber, automated inspection system) by comparing the investment against net annual savings.

The inputs for this scenario

  • Total capital investment in optics line: 125,000 $ (the input this scenario stresses; the baseline uses 250,000)
  • Expected annual savings from new line: 95,000 $ / yr (held at the documented default)
  • Annual support and operating cost: 18,000 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net annual savings = expected annual savings - annual support cost.
  • Payback period works out to 1.62 yr at these inputs, and this is the headline figure for the scenario.
  • Net annual savings works out to 77,000 $ / yr at these inputs.
  • Total capital investment works out to 125,000 $ at these inputs.
  • Five-year net value works out to 260,000 $ at these inputs.

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 50% below the baseline at 1.62 yr.
  • It computes the payback period in years by dividing total capital investment by net annual savings (expected savings minus annual support cost). 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.
