What is Inventory Shrinkage?

Inventory shrinkage refers to the loss of inventory that occurs due to theft, fraud, damage, miscounting, or supplier errors. It represents a significant problem for retailers, warehouses, and businesses as it directly affects profits.

📌 Example: A retail store records 1,000 items in stock, but only 950 items are actually available—this missing 50 items represent inventory shrinkage.

According to the National Retail Federation (NRF), retailers lose billions of dollars annually due to shrinkage, making it a major concern for businesses worldwide.

How to Calculate Inventory Shrinkage?

The Inventory Shrinkage Formula is:

$$\text{Shrinkage} = \left( \frac{\text{Recorded Inventory} - \text{Actual Inventory}}{\text{Recorded Inventory}} \right) \times 100$$

Example Calculation:

• Recorded Inventory Value: $10,000
• Actual Inventory (After Audit): $9,500
• Shrinkage Percentage:

$$\left( \frac{10,000 - 9,500}{10,000} \right) \times 100 = 5\%$$

A high shrinkage percentage indicates significant inventory losses, requiring urgent corrective actions.
