Your numbers
Inventory value and velocity
Use the filled example first. Then replace each field with a measured value or your best current estimate.
Step 1Answer one question at a time. Your example values stay available.
Important limit
Inventory value is only as good as the count and costing method.
Separate obsolete, damaged, quarantined, sample, and consigned stock. Confirm whether labor and overhead belong in inventory under your accounting policy and use sellable velocity that reflects promotions and seasonality.
