Supplier Lot Acceptance Rate Calculator
Measure receiving acceptance for a closed group of supplier lots. Enter accepted lots, all received lots with completed inspection status, and your acceptance target.
What this calculator does
- Measure receiving acceptance across a closed supplier-lot cohort and compare it with your contractual target.
Formula used
- Acceptance rate (%) = accepted count ÷ total count × 100
- Shortfall to target = target percentage − acceptance rate
- Not accepted = total count − accepted count
Inputs explained
- Accepted Supplier Lots: Distinct lots accepted within the reviewed receiving cohort.
- Supplier Lots Received: Received lots in the same cohort after inspection disposition is complete.
- Lot Acceptance Target: Contractual or internal lot-acceptance target for this supplier scope.
How to use the result
- Best suited to supplier receiving Review, contractual acceptance tracking.
- A lot count gives equal weight to large and small lots. The rate does not measure defect frequency within accepted lots.
Current U.S. benchmarks
- Steel mill PPI stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. New factory orders are up 8.5% year over year (Census).
- The U.S. has 11,691 transportation equipment establishments employing about 1,682,910 workers (Census County Business Patterns, 2023).
Common questions
- Can a lot with one rejected part be accepted? Use your governing lot disposition rule. This calculator counts the final status of each lot and does not define an acceptance sampling plan.
- Should I count a resubmitted lot twice? No, use one consistent lot identifier and disposition rule. Duplicate entries would change the denominator without adding a distinct supplied lot.
- What happens to pending inspections? Keep the reporting cohort open until inspection status is complete, or report pending lots separately. Mixing pending and rejected lots distorts acceptance comparisons.
- Does this compare suppliers with different lot sizes? Only on a lot-count basis. Review part quantities and severity separately because a ten-part lot and a thousand-part lot each count once.
