Supplier Payment Terms Impact at 58% fraction of terms change realized: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop fraction of terms change realized to 58%, then walk the calculation through step by step. Estimate payment terms cash impact from spend and working capital rate.

The inputs for this scenario

  • Annual spend with the supplier: 100 units (held at the documented default)
  • Cost of capital per dollar-year: 45 $ / unit (held at the documented default)
  • Fraction of terms change realized: 58 % (the input this scenario stresses; the baseline uses 80)
  • One-time transition cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Weighted cost = quantity × rate × capture factor + fixed adjustment.
  • Total supplier payment terms impact cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Supplier payment terms impact cost per unit works out to 28.6 $ / piece at these inputs.
  • Variable supplier payment terms impact cost works out to 2,610 $ at these inputs.
  • Fixed supplier payment terms impact adder works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where fraction of terms change realized sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to fraction of terms change realized, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It is a working-capital approximation, not a full NPV — it ignores the price increase suppliers often bake in for longer terms and the effect on supplier financial health, both of which can erase the paper gain.
