Days Sales of Inventory DSI: Definition, Formula, Importance

If you ever want to know about the efficiency of inventory management of a firm, you should look at both – inventory turnover ratio and inventory days. The inventory turnover ratio helps us understand the company’s efficiency in handling the inventories. It shows how good the company is to reduce overspending on inventory and how well a company can convert the inventory into finished stocks. Since a major part of the “days in inventory formula” includes the inventory turnover ratio, we need to understand the inventory turnover ratio to comprehend the meaning of the inventory days formula.

One mistake to avoid, however, is to compare the inventory days of companies in completely different industries, as that would be an unfair comparison where the interpretation is likely to be incorrect (i.e. “apples-to-oranges”). Since Walmart is a retailer, it does not have any raw material, works in progress, and progress payments. Find out what you need to do to forecast demand accurately and maximise efficiency and profitability in your business. On top of all of this, one of the biggest factors of importance is that the longer a company keeps inventory, the longer it won’t have access to its cash equivalent. Therefore, the company wouldn’t be able to use these funds for other operations and opportunities. There are two different versions of the DSI formula that can be used, and it depends on the accounting practices of the company.

During that time, the cost of products sold was ₹1,50,000, while the average inventory was ₹30,000. The average inventory balance is thereby used to fix the timing misalignment. A low DSI suggests that a firm is able to efficiently convert its inventories into sales. This is considered to be beneficial to a company’s margins and bottom line, and so a lower DSI is preferred to a higher one.
