Make-Buy, Outsourcing & Network Design worked example

Outsourcing ROI with one-time outsourcing transition investment of 12,500 $: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop one-time outsourcing transition investment to 12,500 $, then walk the calculation through step by step. Estimate outsourcing roi for make-buy, outsourcing and network design using production-ready inputs so teams can screen a capital project before a detailed business case.

The inputs for this scenario

  • One-time outsourcing transition investment: 12,500 $ (the input this scenario stresses; the baseline uses 25,000)
  • Gross annual savings from outsourcing: 18,000 $ / yr (held at the documented default)
  • Annual vendor management and 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 outsourcing roi savings = annual outsourcing roi savings - annual outsourcing roi support cost.
  • Outsourcing roi payback period works out to 0.81 yr at these inputs, and this is the headline figure for the scenario.
  • Net annual outsourcing roi savings works out to 15,500 $ / yr at these inputs.
  • Outsourcing roi investment works out to 12,500 $ at these inputs.
  • Five-year net outsourcing roi value works out to 65,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where one-time outsourcing transition investment 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 one-time outsourcing transition investment, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It treats savings and support cost as flat annual figures and ignores inflation, ramp-down of in-house cost, and the risk premium of depending on a single external supplier.
