How to calculate Share of Items Out of Stock ?
Explanation of the parts of the formula:
- Number of products that are out of stock represents the count of items that are unavailable for purchase due to lack of inventory. These are products that customers cannot order because they are not available.
- Total Items (SKU) refers to the total count of different stock keeping units (SKUs) or individual products that are listed as available in the inventory, irrespective of their stock status.
- The ratio of the number of products that are out of stock to the total items gives a proportion that represents the share of unavailable products.
- Multiplying the ratio by 100 converts the proportion into a percentage, giving the Share of Items Out of Stock as a percentage value which makes it easier to interpret and analyze.
In essence, the “Share of Items Out of Stock” is a metric to gauge the availability of products in an ecommerce store’s inventory. A high percentage indicates that a significant portion of the inventory is unavailable, which could lead to lost sales opportunities, while a lower percentage signifies better stock availability, enhancing the customer’s shopping experience.
Example Scenario
Imagine that an ecommerce store has:
- A total of 500 different items (SKUs) listed on its platform.
- Out of these 500 items, 50 are currently out of stock.
Insert the numbers from the example scenario into the above formula:
- Share of Items Out of Stock = 50/500 x 100
- Share of Items Out of Stock = 0.1 × 100
- Share of Items Out of Stock = 10%.
This means that 10% of the total items listed on the ecommerce store’s platform are currently unavailable for customers to purchase due to lack of stock.
Tips and recommendations for optimizing Share of Items Out of Stock
Maintain a safety stock level
It is important to maintain a safety stock level to account for unexpected spikes in demand. By having a buffer of inventory, you can ensure that products are not immediately out of stock when there is a sudden spike in customer orders.
Effective forecasting
Implementing effective forecasting techniques is critical to accurately predicting product demand. By analyzing historical data, market trends, and customer insights, you can make informed inventory management decisions. As a result, you can optimize inventory levels and avoid out-of-stock situations.
Vendor management
Building strong relationships with vendors and suppliers is essential to minimizing out-of-stocks. Maintaining clear lines of communication and establishing reliable partnerships will ensure timely replenishment of products. By working closely with your vendors, you can synchronize inventory levels and prevent out-of-stocks.
Real-time inventory tracking
Implementing real-time inventory tracking systems allows you to continuously monitor inventory levels. By leveraging technology solutions, you can proactively identify when products are running low and initiate reorder processes in a timely manner. This helps you maintain optimal inventory levels and reduce the risk of out-of-stocks.
Customer alerts
Offering customers the ability to subscribe to out-of-stock notifications is a proactive approach to managing out-of-stocks. By keeping customers informed of product availability, you can recapture lost sales when items are back in stock. This increases customer satisfaction and loyalty by providing transparency and convenience to their shopping experience.

Limitations of using Share of Items Out of Stock
While the Share of Items Out of Stock is a vital metric for understanding inventory effectiveness in an ecommerce setting, it comes with its own set of limitations when used in business analysis:
- Doesn’t Reflect Customer Demand: This metric indicates what percentage of products are out of stock, but it doesn’t provide insights into the demand for those products. High-demand products being out of stock is a more severe issue compared to low-demand products being unavailable.
- Not Always Indicative of Lost Sales: Just because an item is out of stock doesn’t necessarily mean a sale is lost. Customers may wait for the item to be restocked or may choose an alternative product available on the website.
- Lacks Granularity: “Share of Items Out of Stock” is a general metric and doesn’t differentiate between product categories or segments. The impact of a stockout can vary greatly depending on the specific product or category.
- No Insights into Duration: The metric doesn’t provide information on how long items have been out of stock. An item being out of stock briefly is different from an item being unavailable for an extended period.
- May Not Reflect Supplier Reliability: While it shows the share of items not available, it doesn’t necessarily reflect the reasons behind it, such as supplier delays or other supply chain issues.
- Not Directly Linked to Customer Satisfaction: This metric alone doesn’t tell us about customer satisfaction or dissatisfaction. An item might be out of stock, but if it’s not a high-demand product or if alternatives are available, it might not affect customer satisfaction significantly.
- Sensitive to External Factors: External factors such as supply chain disruptions, natural disasters, or global events can influence this metric, making it variable and at times unpredictable.
- Requires Regular Updates: For this metric to be meaningful, it requires regular, if not real-time, updates. Outdated information may lead to incorrect analysis and decision-making.
In summary, while out-of-stocks is a critical metric for measuring inventory effectiveness, it should not be used in isolation. It should be analyzed in conjunction with other relevant metrics and qualitative insights for a more complete understanding of business performance and customer satisfaction.
KPIs and metrics relevant to Share of Items Out of Stock
- Inventory Turnover Rate: It measures how often the inventory is sold and replaced over a period. A high turnover rate may sometimes lead to items being out of stock.
- Backorder Rate: The metric shows the frequency at which items are backordered and can be analyzed alongside the out-of-stock rate to optimize inventory.
- Sales Conversion Rate: This indicates the effectiveness of the sales strategy. A lower conversion rate might be linked with high out-of-stock situations.
Final thoughts
Managing out-of-stock rates is critical for e-commerce businesses to ensure revenue consistency, customer satisfaction, and overall operational efficiency. By carefully monitoring and optimizing this metric, companies can strike a balance in their inventory management to avoid excessive out-of-stocks and ensure a smooth shopping experience for customers.
