Shipment Accuracy at 99% target shipment accuracy rate: a worked example

What does the result look like when target shipment accuracy rate reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when shipment accuracy in wms, warehouse labor and fulfillment needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Shipments with errors: 8 count (unchanged)
  • Total shipments audited: 250 count (unchanged)
  • Target shipment accuracy rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Shipment accuracy rate = shipment accuracy count ÷ total shipment accuracy population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for shipment accuracy rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for shipment accuracy gap to target.
  • At this operating point the engine returns 8 count for shipment accuracy count.
  • At this operating point the engine returns 250 count for total shipment accuracy population.

How this compares with the baseline

  • Against the tool's baseline example, where target shipment accuracy rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • A figure at this level is achievable when target shipment accuracy rate is genuinely sustained, not just peaked for a shift. The result is only as sound as the sample — a small or non-random audit of 250 shipments can badly misrepresent the true population rate, so widen the sample before acting on the number.
