Inventory Shrinkage FAQs

Shrinkage is often considered unavoidable in the retail and supply chain sectors because of the numerous variables that can lead to loss. Despite best efforts, factors such as human error, theft, damage, and spoilage are realities of managing large inventories. Even with stringent control measures, some degree of loss is typically expected due to these unforeseen or uncontrollable events.

The average shrinkage rate in retail varies by industry and country, but it is commonly reported to be around 1-2% of sales. This figure can be influenced by multiple factors, including the type of merchandise sold, the effectiveness of loss prevention strategies, and the geographical location of the stores.

Controlling shrinkage is a collective responsibility that involves several roles within an organization. While loss prevention teams or security personnel may lead the efforts, employees at all levels contribute to minimizing shrinkage. Professional warehousing services can be used to help control shrinkage.

Inventory shrinkage is reported in the financial statements as a reduction in the value of inventory on hand, which directly affects the cost of goods sold (COGS) and, consequently, the net income. When shrinkage in warehouse occurs, the inventory asset account is decreased, and an expense account (such as “Shrinkage” or “Inventory Shortage”) is increased, which is then reflected in the income statement as part of COGS or a separate line item, depending on the accounting policies of the company.
