It is calculated by dividing the gross margin by the average inventory cost and is used to help a company evaluate the effectiveness of their inventory investment. Higher GMROI values indicate a company has a strong ability to turn inventory into cash.

Key Takeaways


  1. Efficiency measurement: GMROI is a brilliant inventory profitability evaluation ratio that measures the return on investment from inventory. It helps businesses understand how efficiently they’re converting their inventory investment into profits.
  2. Business Improvement: By determining the GMROI, a business can identify less profitable products that tie up lots of money in inventory costs and can adjust their strategies to improve overall profitability. This could be done by investing more in inventory that produces higher GMROI.
  3. Calculation: The GMROI is calculated by dividing the gross margin by the average inventory cost. Essentially, it’s expressing the relationship between the total profit made from sold inventory and the cost of that inventory. This opens up avenues to understand the profitability of each product sold so managers can make informed business decisions.



Gross Margin Return on Investment (GMROI) is an important term in business/finance as it provides a useful, profitability-linked metric for inventory management. It measures the profitability or the gross margin return per dollar of investment in inventory. This evaluation is crucial as it assists businesses in understanding which products are yielding the highest returns per dollar invested. Hence, it guides decisions regarding inventory stocking and helps optimize profitability. A high GMROI indicates that a company is selling merchandise profitably and its inventory management is efficient, which is vital when it comes to managing cash flows and investment returns in any business.


Gross Margin Return on Investment (GMROI) is a profitability metric used primarily by businesses in retail or industries dealing with large volumes of inventory. Its purpose is to determine how profitably a business can convert its inventory investment into gross profit. In simpler terms, GMROI tells the business how much it earns for every dollar it has invested in the inventory. This indicator helps decision-makers understand the effectiveness of their inventory management and provides insight into whether inventory investments are generating competitive profits.Consider the GMROI as a tool that helps in merchandising decisions, price optimization, and inventory control. For instance, a higher GMROI indicates a company’s ability to turn inventory into cash above the cost of the inventory, reflecting efficient operations. A low GMROI, on the other hand, suggests a mismatch between inventory management and sales, prompting the need for strategy adjustment. Furthermore, when comparing different products, product lines or departments within the business, GMROI can also be used to identify which areas are driving more profitability and which areas may need attention or reform.


1. Retail Clothing Store: An upscale clothing store calculates its Gross Margin Return on Investment (GMROI) to assess the profitability of its various product lines. For instance, they sell designer jeans with a gross margin of 60% and the average inventory cost was $20,000. The annual sales was $60,000. Calculating the GMROI, they get 1.8 ($60,000 * 60% / $20,000), indicating each dollar invested in inventory yielded $1.8 in gross return. This helped them make decision on inventory management and buying patterns.2. Supermarket Chain: In a supermarket, management uses GMROI to optimize their product placement. They found their high GMROI items (like processed food with high margin and fast turnover) and place these products at prominent positions to boost sales. Lower GMROI items were still sold, but without prime placement, leading to an overall increase in profitability.3. Electronics Company: A consumer electronics firm uses GMROI to analyze the profitability of their distinct product categories, such as televisions, laptops, and cell phones. If the GMROI for laptops is higher compared to other product categories, the company might decide to invest more in that sector by increasing inventory, improving marketing and sales efforts for those products.
