Understanding Inventory Accuracy Rate
How we calculate. Accuracy % = matched locations ÷ locations counted × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Inventory Accuracy Rate case uses correct locations 9700 and locations counted 10000. Enter the same figures below to reproduce the worked path.
What is Inventory Accuracy Rate?
A WMS data-quality KPI that drives fill rate and picking accuracy. Define “correct” as exact match or within tolerance.
- Location or SKU basis
- Publish match tolerance
- Higher is better
The Formula
Worked Example
Common Use Cases
- Cycle count programs: WMS trust
- Slotting QA: location integrity
- Audit readiness: book-to-floor
Pro Tips
- Separate variance value % if needed
- Root-cause mis-slots vs theft
- Pair with picking accuracy
Limitations: Inventory Accuracy Rate results are educational logistics and supply-chain planning aids—not SLAs, carrier contracts, or inventory valuation advice. Confirm definitions with your WMS/TMS and finance policies.
FAQ
Unit accuracy vs location accuracy?
This form is location (or SKU) match rate. Unit accuracy weights by quantity—use a labeled variant if required.
What if locations counted is 0?
Accuracy is undefined—enter a positive count of locations audited.
