For savvy retailers, that means treating inventory like an investment in the stock market. You try to buy at the lowest possible price and sell at a profit when demand is high. A simple calculation called Gross Margin Return on Investment (GMROI) can help you determine if you are getting the best return on that investment.<\/p>\n
Donaldson Brown, a young electrical engineer who began his career as a salesman with DuPont in 1912 and finished in 1946 as the vice president of finance for General Motors, introduced the concept of return on investment (ROI) in 1914. It worked so well, DuPont adopted the formula (ROI = (Gain from Investment \u2013 Cost of Investment)\/Cost of Investment) and used it to monitor the performance of virtually all the its investments. It became known as the DuPont Method, or Model, was taught in business schools across the country and used by many companies. GMROI has evolved from Brown\u2019s simple investment measurement.<\/p>\n
The North American Retail Hardware Association\u2019s Cost of Doing Business Study considers GMROI one of the most important tools in determining how profitable your business can be. And by knowing the GMROI of your store, a department, or a specific product, you can make decisions and take steps toward improving your business\u2019 bottom line.

Dividing gross profit by inventory investment and multiplying the result by 100 gives you the GMROI on a specific item. The calculation can be made simply from information pulled from your sales and inventory data, and it tells you if the products you buy are making money.

Gross Profit Dollars \u00f7\u00a0Inventory Investment\u00a0\u00d7\u00a0100\u00a0=\u00a0GMROI<\/strong><\/div><\/div> An inventory\u2019s monthly median value, also known as average inventory, is an item\u2019s price minus discounts, plus freight and taxes. It is determined by adding the beginning cost of inventory for each month to the ending cost inventory for the previous month and dividing by 2.<\/p>\n The GMROI for this drill is $150 divided by $75, or 2.00. Multiply that by 100 and it means the store is getting a 200% return on its investment. If items are being sold with a GMROI value of greater than 100%, the store is making a profit, however it is typical to see a well-run store with a GMROI over 300%. No matter how experienced you are at managing inventory, there are going to be times when some items won\u2019t move. Maybe you buy too much. Maybe demand drops for a historically strong item. Maybe an unusual cold snap or heatwave kills sales of seasonal items. How do you track thousands of items? Whatever happens, the time those products sit on your shelves ties up cash that could be used to purchase new inventory. So, the key for retailers comes down to a simple concept: You must have the right products at the right time to make productive sales.<\/p>\n Since up to 80% of a typical retailer\u2019s total assets are made up of inventory, knowing what a store\u2019s GMROI is crucial to understanding its inventory investment. Calculating the GMROI also allows retailers to see how the big-box practice of buying in bulk isn\u2019t always the prudent way to stock a store. Suppliers routinely offer lower per-item prices to retailers who place larger orders. But if those items aren\u2019t all sold in a typical sales cycle and remain in inventory, the money spent on getting a better deal could be a wasted investment, tying up cash that could be used on future orders. So, knowing a product\u2019s GMROI at various price points can make paying more for fewer items a wiser inventory investment strategy.<\/p>\n To illustrate the impact of order quantity on GMROI, consider an item that typically requires a $48 investment due to high order minimums, and how paying a slightly higher purchase price results in a higher GMROI.<\/p>\n Supplier 1 requires a minimum order of 24 units at $2.00 each. Supplier 2 has no minimum, and sells the same unit for $2.35 each. Supplier 3 requires a minimum order of 6 and a purchase price of $2.15 per unit. A higher purchase price more than doubled GMROI when using Supplier 2 or Supplier 3. Yes, the profit (in dollars) was lower. However, we have $33.90-$35.10 left to invest in another product in the two scenarios with higher purchase costs and lower order minimums. If we invest those dollars in another item that meets our required 300% GMROI, the profit dollars are recouped.<\/p>\n While the GMROI calculation can be used to measure the profitability of a single item, a department or an entire store, the Retail Owners Institute, a self-help financial management resource for retailers, says the use of GMROI to compare the productivity of different departments within a store is probably its most valuable use. For instance, in the example below, a department with low annual sales, low annual gross margins, and low average inventory costs but a high turn rate (Department D), could be as valuable to a retailer as a department with high annual sales, a higher gross margin, and higher average inventory costs, but a low turn rate (Department A). Comparing those two department\u2019s GMROI allows retailers to see how each one contributes to the success of a business. The same comparisons can be made on individual products or entire businesses.<\/p>\n Source: The Retail Owners Institute <\/em><\/span><\/p>\n For the past 100 years, the NRHA\u2019s Cost of Doing Business Study has analyzed the sales data of hardware stores, home centers and lumber yards.

You can even control inventory right at the cash register with point of sale systems. POS software records each sale when it happens, so your inventory records are always up to date.\u201d<\/p>\n Simply put, strong retail technology solutions help you calculate GMROI which allows you to predict future sales cycles and customize your inventory to meet consumer demand.

It is a tool to check on the health of your ordering and inventory processes. Much like when your doctor tells you that you have high blood pressure. It\u2019s up to you to take steps to remedy that issue. You eat a balanced diet, exercise more and have follow up exams. GMROI is a simple calculation that helps you determine your business\u2019 financial health.

\nHow does the GMROI calculation work? Let\u2019s say a hardware store buys an electric drill for $50 and sells the product for $150. The gross profit on the item is $100. Because of variables such as discounts, shipping costs and taxes, the inventory\u2019s median value throughout the year is $75.<\/p>\n
