What does ITR – Inventory Turnover Ratio mean in Shopify?

If you are running an eCommerce business using the Shopify platform, you have probably heard of Inventory Turnover Ratio (ITR). But what does this term mean, and why is it important for your business? In this article, we will explore the definition of ITR, how to calculate it in Shopify, and its impact on your business performance. We will also discuss strategies to improve your ITR and benchmark it against industry standards. Let's get started!

Understanding Inventory Turnover Ratio (ITR)

Inventory Turnover Ratio is a financial metric used to measure how quickly a company is selling its inventory and replacing it with new stock. Essentially, it shows how efficiently a company is managing its inventory levels and cash flow. A high ITR indicates that the company is selling its inventory quickly, which is desirable, as it generates cash flow and reduces the risk of stock obsolescence or spoilage. On the other hand, a low ITR may indicate poor inventory management or slow sales, which can impact the company's profitability and growth.

Definition of Inventory Turnover Ratio

The Inventory Turnover Ratio formula is calculated by dividing the cost of goods sold (COGS) by the average inventory for the period:
ITR = Cost of Goods Sold / Average Inventory
The COGS includes all the direct costs associated with producing or acquiring the products sold. The average inventory is calculated by adding the beginning inventory and ending inventory for the period and dividing by two. The resulting ratio shows how many times the company's inventory is sold and replaced during the period.

Importance of ITR in eCommerce

ITR is a critical metric for eCommerce businesses, as it directly impacts their cash flow, profitability, and customer satisfaction. By tracking their ITR, businesses can identify trends in their sales and inventory levels and adjust their strategies accordingly. For example, if the ITR is decreasing, it may be a sign that the business is overstocking or not selling enough, indicating a need to adjust pricing or marketing efforts. Similarly, if the ITR is increasing, it may be a sign that the business is running out of stock or not ordering enough, indicating a need to optimize inventory management or supply chain.
Moreover, ITR can help businesses to make informed decisions about their inventory levels. By analyzing the ITR, businesses can determine the optimal inventory levels to maintain, which can help them to avoid stockouts or overstocking. Maintaining the right inventory levels can also improve customer satisfaction, as it ensures that products are available when customers want to buy them.
Another benefit of tracking ITR is that it can help businesses to identify inefficiencies in their supply chain. By analyzing the ITR, businesses can determine if there are any bottlenecks or delays in the supply chain that are impacting their inventory turnover. This information can help businesses to optimize their supply chain, reduce costs, and improve their overall efficiency.
Overall, ITR is a critical metric for any business that sells products. By tracking this metric, businesses can gain valuable insights into their inventory management, supply chain, and profitability. By optimizing their ITR, businesses can improve their cash flow, reduce costs, and increase customer satisfaction, which can help them to achieve long-term success.

Calculating Inventory Turnover Ratio in Shopify

Inventory turnover ratio (ITR) is a crucial metric for any business that deals with physical products. It measures how many times a company's inventory is sold and replaced over a given period, indicating how efficiently it manages its stock levels. A high ITR means that a company is selling its products quickly and replenishing them promptly, while a low ITR suggests that it's holding onto its inventory for too long, which can lead to waste, obsolescence, and cash flow problems.
Now that we know what ITR is and why it's important let's see how to calculate it in Shopify. The good news is that Shopify provides all the data you need to calculate your ITR automatically. Here's a step-by-step guide:

Step-by-step Guide to Calculate ITR

  1. Log in to your Shopify account and navigate to "Analytics" > "Reports."
  1. Select "Finance Report" and set the date range for the period you want to analyze.
  1. Scroll down to the "Cost of Goods Sold (COGS)" section and note the total COGS for the period.
  1. Scroll up to the "Inventory Value" section and note the beginning and ending inventory values for the period.
  1. Calculate the average inventory value by adding the beginning and ending values and dividing by two.
  1. Use the ITR formula to calculate your ratio for the period.
It's important to note that Shopify calculates your ITR based on the cost of goods sold, not the revenue. This is because the COGS reflects the direct cost of producing or acquiring the products, while the revenue includes all the overhead costs, such as marketing, shipping, and taxes. By using the COGS, you can get a more accurate and actionable ITR that reflects your inventory management performance.

Factors Affecting ITR Calculation

While calculating ITR in Shopify is relatively straightforward, there are some factors that can impact its accuracy. For example, if you sell different types of products at different margins, the COGS may not reflect the true cost of selling each product. Similarly, if you use a fulfillment center or dropshipping, the inventory value may not accurately reflect the actual stock levels. To mitigate these issues, it's important to review your ITR regularly and adjust your accounting practices and data sources accordingly.
In addition to these factors, there are other variables that can affect your ITR, such as seasonality, market trends, and competition. For instance, if you operate in a highly competitive market, you may need to adjust your pricing or marketing strategy to boost your sales and turnover. Similarly, if you sell seasonal products, you may need to adjust your inventory levels and ordering patterns to avoid stockouts or excess inventory.
Another factor to consider is the impact of external events, such as natural disasters, pandemics, or economic downturns. These events can disrupt supply chains, affect consumer demand, and lead to inventory imbalances. To mitigate these risks, it's important to have contingency plans in place, such as alternative sourcing options, safety stock levels, and flexible fulfillment options.
Ultimately, the key to optimizing your ITR is to have a holistic approach to inventory management that takes into account all the relevant factors and data sources. By using tools like Shopify's analytics and reports, you can get a comprehensive view of your inventory performance and make data-driven decisions to improve your business's efficiency, profitability, and resilience.

Analyzing Your ITR Results

Now that you have your ITR results let's see how to interpret them and take action based on them.

What is a Good Inventory Turnover Ratio?

There is no one-size-fits-all answer to what constitutes a good ITR, as it depends on various factors, such as the industry, the business model, and the product lifecycle. Generally, a high ITR is desirable, as it indicates that the company is selling its inventory quickly and efficiently. However, a very high ITR, such as above 10, may suggest that the company is not holding enough inventory to meet demand or missing out on opportunities to upsell or cross-sell. On the other hand, a very low ITR, such as below 1, may suggest that the company is overstocking or carrying obsolete inventory, tying up cash flow and storage space.

Benchmarking Your ITR Against Industry Standards

To get a better sense of how your ITR compares to your peers or competitors, you can use industry benchmarks or averages. For example, the National Retail Federation (NRF) reports an average ITR of 4.5 for general merchandise retailers. However, these benchmarks should be used with caution, as they may not reflect your specific business circumstances or strategies.

Strategies to Improve Inventory Turnover Ratio

If your ITR is lower than desired, or you want to further optimize your inventory management, here are some strategies to consider:

Streamlining Inventory Management

One of the most effective ways to improve ITR is to optimize your inventory management practices. This includes identifying your best-selling products, minimizing stock-outs and overstocking, and using tools such as inventory forecasting and replenishment. By having a better handle on your inventory levels and trends, you can prevent excess inventory, reduce waste, and improve cash flow.

Implementing Demand Forecasting

Demand forecasting is the process of predicting customer demand for your products based on historical data, market trends, and other factors. By using demand forecasting software or services, you can better plan your inventory levels and ordering cycles, avoiding stock shortages and surpluses. You can also use demand forecasting to identify new opportunities for product development or marketing.

Optimizing Pricing and Promotions

Pricing and promotions can also impact your ITR by affecting customer demand, order frequency, and product category mix. By using pricing and promotions tools, such as dynamic pricing, quantity discounts, and personalized offers, you can incentivize customers to buy more, buy faster, and buy different products. You can also use pricing and promotions to liquidate excess inventory, launch new products, and test new markets.

The Impact of ITR on Business Performance

Finally, it's important to understand how ITR affects your business performance beyond financial metrics. Here are some examples:

Cash Flow and Working Capital

A high ITR can lead to a positive cash flow cycle, as the company can convert inventory into cash faster and reduce the need for external financing. On the other hand, a low ITR can tie up cash flow and working capital in excessive inventory, reducing the company's flexibility and liquidity.

Customer Satisfaction and Retention

A high ITR can also lead to higher customer satisfaction and retention, as the company can fulfill orders faster and more reliably. This can result in positive word-of-mouth, repeat purchases, and brand loyalty. On the other hand, a low ITR can lead to stockouts, delayed shipments, and order cancellations, negatively impacting the customer experience and reputation.

Profitability and Growth

A high ITR can ultimately lead to higher profitability and growth, as the company can reinvest the cash generated from sales into product development, marketing, and expansion. This can result in increased market share, economies of scale, and competitive advantage. On the other hand, a low ITR can limit the company's profitability and growth potential, as it may lead to higher costs, lower margins, and missed opportunities.


In summary, Inventory Turnover Ratio (ITR) is a critical metric for eCommerce businesses using Shopify to manage their inventory levels and cash flow. By understanding ITR, calculating it, and analyzing its results, businesses can optimize their inventory management practices, improve customer satisfaction and retention, and ultimately drive profitability and growth. By implementing strategies such as streamlining inventory management, implementing demand forecasting, and optimizing pricing and promotions, businesses can further improve their ITR and gain a competitive advantage.
