Shrinkage is a crucial metric that businesses need to track and understand. It refers to the difference between the amount of inventory that a business acquires and the actual amount available for sale. In retail, it’s vital to accurately calculate shrinkage to maintain inventory control, minimize losses, and improve overall operations. In this article, we will explore what affects shrinkage and provide a step-by-step guide to calculating it in your business operations.
Factors Affecting Shrinkage
Shrinkage can occur for various reasons, including but not limited to:
1. Theft: External theft (shoplifting) or internal theft (employee theft) are prevalent factors contributing to shrinkage.
2. Damage: Items can be damaged during shipping, stocking, or by customers, rendering them unsalable.
3. Clerical Errors: Accidental data entry mistakes or misplacement of items can cause discrepancies in inventory records.
4. Vendor Fraud: Suppliers might deliver fewer items than invoiced or provide counterfeit goods.
Step-by-Step Guide to Calculating Shrinkage
1. Conduct a Physical Inventory Count
A physical inventory count is essential to have accurate figures for calculating shrinkage. This process involves counting all items physically present in the storage area or warehouse and on sales floors. Record the total number of each item you have in stock during the count.
2. Compare the Physical Count with Recorded Inventory
Once you’ve completed the physical count, compare these numbers against what’s recorded in your inventory management system as on-hand inventory. Identify and make note of any discrepancies between the two data sets.
3. Determine the Cost of Goods Sold (COGS)
To calculate shrinkage, you’ll need to know your Cost of Goods Sold (COGS) over a specific period (e.g., monthly, quarterly, or yearly). COGS is calculated as follows:
COGS = Beginning Inventory + Purchases – Ending Inventory
4. Calculate Shrinkage
To determine shrinkage, you’ll need to compare the actual COGS (based on your physical inventory count) with the expected COGS (based on your recorded inventory). Use the formula below:
Shrinkage = (Expected COGS – Actual COGS) / Expected COGS x 100%
This formula will yield the shrinkage percentage.
Example:
Suppose your expected COGS is $40,000 and your actual COGS based on your physical inventory count is $36,000. The shrinkage can be calculated as follows:
Shrinkage = (($40,000 – $36,000) / $40,000) x 100% = 10%
Your shrinkage rate is 10% in this example.
Conclusion
Understanding and effectively calculating retail shrinkage is necessary for businesses to identify issues related to theft, damages, and inefficiencies. By consistently conducting physical inventory counts and comparing them against recorded inventory data, companies can proactively address problems resulting in shrinkage and take steps to improve their overall operational efficiency.
