Fastening Automation Payback with installed fastening automation investment of 62,500 $: a worked example

Suppose installed fastening automation investment falls to 62,500 $. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate payback for fastening automation from installed investment, annual savings, and annual support cost.

The inputs for this scenario

  • Installed fastening automation investment: 62,500 $ (the input this scenario stresses; the baseline uses 125,000)
  • Annual fastening automation savings: 72,000 $ / yr (held at the documented default)
  • Annual automation support cost: 9,000 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net annual fastening automation savings = annual savings - annual support cost.
  • Fastening automation payback period works out to 0.99 yr at these inputs, and this is the headline figure for the scenario.
  • Net annual automation savings works out to 63,000 $ / yr at these inputs.
  • Installed automation investment works out to 62,500 $ at these inputs.
  • Five-year net automation value works out to 252,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where installed fastening automation investment sits at 125,000 $ and the headline result is 1.98 yr, this scenario comes in 50% below the baseline at 0.99 yr.
  • It computes the payback period in years and five-year net value by dividing installed investment by annual savings net of 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.
