Screw Feeder ROI with installed screw-feeder project cost of 80,000 $: a worked example

This scenario runs the screw feeder roi calculation on the strong side: installed screw-feeder project cost of 80,000 $, with every other input held at its documented default. Use it when evaluating bowl feeders, step feeders, escapements, screw presenters, or automated screw delivery for an assembly station.

The inputs for this scenario

  • Installed screw-feeder project cost: 80,000 $ (raised for this scenario; the documented default is 32,000)
  • Annual screw-feeder savings: 21,000 $ / yr (unchanged)
  • Annual feeder support cost: 3,500 $ / yr (unchanged)

Working through the calculation

  • Applying the documented formula (Net annual screw-feeder savings = annual savings - annual support cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4.57 yr for screw-feeder payback period, the number this scenario is built around.
  • At this operating point the engine returns 17,500 $ / yr for net annual screw-feeder savings.
  • At this operating point the engine returns 80,000 $ for installed feeder investment.
  • At this operating point the engine returns 7,500 $ for five-year net feeder value.

How this compares with the baseline

  • Against the tool's baseline example, where installed screw-feeder project cost sits at 32,000 $ and the headline result is 1.83 yr, this scenario comes in 150% above the baseline at 4.57 yr.
  • Use it when justifying a screw-feeder retrofit or comparing auto-feed options against the current manual or bit-pickup method on a fastening station. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Screw-feeder payback period: 4.57 yr (headline result)
