Supplier Lot Acceptance Rate at 71% contractual supplier acceptance target: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop contractual supplier acceptance target to 71%, then walk the calculation through step by step. Calculate supplier lot acceptance from accepted lots, received lots, and the required supplier quality target.

The inputs for this scenario

  • Supplier lots accepted at receiving inspection: 86 lots (held at the documented default)
  • Supplier lots received for inspection: 94 lots (held at the documented default)
  • Contractual supplier acceptance target: 71 % (the input this scenario stresses; the baseline uses 98)

Working through the calculation

  • The calculation starts from the formula this tool documents: Supplier lot acceptance rate = accepted supplier lots ÷ supplier lots received × 100.
  • Supplier lot acceptance rate works out to 91.49 % lot acceptance at these inputs, and this is the headline figure for the scenario.
  • Acceptance gap to target works out to -20.49 percentage points at these inputs.
  • Supplier lots accepted works out to 86 lots at these inputs.
  • Supplier lots received works out to 94 lots at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where contractual supplier acceptance target sits at 98% and the headline result is 91.49 % lot acceptance, this scenario lands almost exactly on the baseline at 91.49 % lot acceptance.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to contractual supplier acceptance target, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Lot count alone ignores lot size and defect severity — one rejected 5,000-piece lot of flight-critical fasteners is not equivalent to one rejected 12-piece lot of brackets.

  • Supplier lot acceptance rate: 91.49 % lot acceptance (headline result)
