Manufacturing Project Portfolio & Capex worked example

Project Payback with project investment and implementation cost of 12,500 $: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop project investment and implementation cost to 12,500 $, then walk the calculation through step by step. Estimate project payback for manufacturing project portfolio and capex using production-ready inputs so teams can screen a capital project before a detailed business case.

The inputs for this scenario

  • Project investment / implementation cost: 12,500 $ (the input this scenario stresses; the baseline uses 25,000)
  • Annual savings delivered by the project: 18,000 $ / yr (held at the documented default)
  • Annual run / support cost: 2,500 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net annual project payback savings = annual project payback savings - annual project payback support cost.
  • Project payback payback period works out to 0.81 yr at these inputs, and this is the headline figure for the scenario.
  • Net annual project payback savings works out to 15,500 $ / yr at these inputs.
  • Project payback investment works out to 12,500 $ at these inputs.
  • Five-year net project payback value works out to 65,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where project investment and implementation cost sits at 25,000 $ and the headline result is 1.61 yr, this scenario comes in 50% below the baseline at 0.81 yr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to project investment and implementation cost, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It ignores discounting, benefit ramp-up, and the risk that projected savings never fully materialize, so verify the savings estimate before trusting the payback.

Results at a glance

  • Project payback payback period: 0.81 yr (headline result)
