Supplier Quote Comparison at 110% share of volume on a true like-for-like quote: a worked example

This scenario runs the supplier quote comparison calculation on the strong side: 110% share of volume on a true like-for-like quote, with every other input held at its documented default. choosing between supplier quotes for material, components, tooling, or outside services

The inputs for this scenario

  • Per-unit price gap between supplier quotes: 2.85 $ / unit (unchanged)
  • Annual buy quantity affected by the switch: 4,200 units (unchanged)
  • Share of volume on a true like-for-like quote: 110 % (raised for this scenario; the documented default is 100)
  • Confidence the quoted price will hold: 95 % (unchanged)

Working through the calculation

  • Applying the documented formula (gross supplier quote impact = supplier quote cost difference per unit × affected buy quantity) to the inputs above produces each figure below.
  • At this operating point the engine returns 12,509 $ for comparable supplier quote impact, the number this scenario is built around.
  • At this operating point the engine returns 11,970 $ for gross supplier quote impact.
  • At this operating point the engine returns -1,197 $ for supplier quote impact outside comparable scope.
  • At this operating point the engine returns 658 $ for supplier quote impact at risk from confidence.

How this compares with the baseline

  • Against the tool's baseline example, where share of volume on a true like-for-like quote sits at 100% and the headline result is 11,372 $, this scenario comes in 10% above the baseline at 12,509 $.
  • Use it during a quote bake-off or resourcing decision when two vendors are within a few dollars per unit and you need to know whether the gap is material after risk. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
