Screw Feeder ROI with installed screw-feeder project cost of 16,000 $: a worked example

Suppose installed screw-feeder project cost falls to 16,000 $. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate payback for an automatic screw feeder from installed project cost, annual labor or cycle-time savings, and annual support cost.

The inputs for this scenario

  • Installed screw-feeder project cost: 16,000 $ (the input this scenario stresses; the baseline uses 32,000)
  • Annual screw-feeder savings: 21,000 $ / yr (held at the documented default)
  • Annual feeder support cost: 3,500 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net annual screw-feeder savings = annual savings - annual support cost.
  • Screw-feeder payback period works out to 0.91 yr at these inputs, and this is the headline figure for the scenario.
  • Net annual screw-feeder savings works out to 17,500 $ / yr at these inputs.
  • Installed feeder investment works out to 16,000 $ at these inputs.
  • Five-year net feeder value works out to 71,500 $ at these inputs.

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 50% below the baseline at 0.91 yr.
  • It computes the payback period in years by dividing the installed screw-feeder project cost by net annual savings, where net savings equal gross annual savings minus the annual feeder 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.

Results at a glance

  • Screw-feeder payback period: 0.91 yr (headline result)
