Definition & Explanation

Inventory aging tracks how long individual stock items have been held since their receipt, purchase, or production date. Warehouse managers and logistics operators rely on this metric to detect obsolescence risk early and keep carrying costs in check. Once items cross defined age thresholds, the metric typically triggers concrete responses: accounting write-downs, markdown strategies to accelerate movement, or, for perishable goods, coordinated clearance actions. Inventory aging differs from average dwell time in that it is measured at the individual lot or SKU level rather than as a warehouse-wide average.
