Storeroom Inventory Accuracy at 99% target storeroom inventory accuracy: a worked example

This scenario runs the storeroom inventory accuracy calculation on the strong side: 99% target storeroom inventory accuracy, with every other input held at its documented default. a maintenance or asset-management team needs to identify count discipline, transaction, kitting, or issue-return problems that create stockout risk for a storeroom cycle count period

The inputs for this scenario

  • Cycle-count lines matching system on-hand balance: 920 count (unchanged)
  • Total MRO inventory lines counted: 1,000 count (unchanged)
  • Target storeroom inventory accuracy: 99 % (raised for this scenario; the documented default is 97)

Working through the calculation

  • Applying the documented formula (Storeroom Inventory Accuracy rate = cycle-count lines matching system balance ÷ MRO inventory lines counted × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 92 % for storeroom inventory accuracy rate, the number this scenario is built around.
  • At this operating point the engine returns 7 points for storeroom inventory accuracy gap to target.
  • At this operating point the engine returns 920 count for cycle-count lines matching system balance.
  • At this operating point the engine returns 1,000 count for mro inventory lines counted.

How this compares with the baseline

  • Against the tool's baseline example, where target storeroom inventory accuracy sits at 97% and the headline result is 92 %, this scenario lands almost exactly on the baseline at 92 %.
  • Use it after each cycle-count cycle or monthly storeroom audit to track whether record accuracy is trending toward your reliability target. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Storeroom Inventory Accuracy rate: 92 % (headline result)
  • Storeroom Inventory Accuracy gap to target: 7 points
  • cycle-count lines matching system balance: 920 count
  • MRO inventory lines counted: 1,000 count
