Inventory turnover

Inventory turnover describes how often inventory is replenished or sold within a specific period. This metric thus shows how quickly goods move through the warehouse and how efficiently tied-up capital remains in circulation.

In many cases, a high inventory turnover indicates good inventory movement, short holding periods, and efficient use of warehouse space. A low inventory turnover, on the other hand, can indicate excess inventory, slow-moving items, or an inadequate inventory strategy. This metric is a particularly important indicator of the quality of inventory management in retail, distribution, and production supply.

However, inventory turnover cannot be evaluated in isolation. A very high turnover can also mean that inventory levels are being kept too low, thereby increasing the risk of stockouts. Conversely, a low turnover is not necessarily problematic in every case, for example when strategic buffer stocks are required. It is therefore crucial to assess it within the context of service levels, demand structure, and lead times.

In conjunction with metrics such as inventory coverage, capital tied up, and delivery capability, inventory turnover provides valuable insights into how economically inventory levels are actually managed.
