Supplier Lot Acceptance Rate Calculator

Supplier lot acceptance rate shows whether incoming aerospace suppliers are delivering usable lots without added containment, source inspection, or MRB review. It helps supplier quality teams decide where to focus audits, corrective actions, and supplier development effort.

What this calculator does

  • Calculate supplier lot acceptance from accepted lots, received lots, and the required supplier quality target.
  • a supplier quality manager needs to compare accepted incoming lots against the supplier performance target
  • Returns the percent of supplier lots accepted without rejection or hold.

Formula used

  • Supplier lot acceptance rate = accepted supplier lots ÷ supplier lots received × 100
  • Acceptance gap to target = supplier lot acceptance rate - supplier acceptance target

Inputs explained

How to use the result
