It’s the rate at which a company replenishes inventory in any given period due to sales. The figure is calculated by dividing the cost of goods by the average inventory. The days sales of inventory (DSI) is an important financial ratio and metric that helps indicate how much time in days that it takes a company to turn its inventory.

  • Days sales outstanding (DSO) and days payable outstanding (DPO) are the other two parts of CCC, which measure how long it takes to receive accounts receivable payments.
  • A company may change its method for calculating the cost of goods sold, such as by capitalizing more or fewer expenses into overhead.
  • This means Keith has enough inventories to last the next 122 days or Keith will turn his inventory into cash in the next 122 days.
  • Both investors and creditors want to know how valuable a company’s inventory is.
  • Each fridge, dishwasher, and other appliance takes up room, requires insurance, and risks damage.

The following two companies develop and sell semiconductor chips for diverse applications like phones, cars, and computers. Then, when we have the values for 3 to 5 years, we can conclude whether the efficiency increases or decreases. Both of them will record such items as inventory, so the possibilities are limitless; however, because it is part of the business’s core, defining methods for inventory control becomes essential.

Inventory turnover and DSI are similar, but they do not measure the same thing. DSI measures the average number of days it takes to convert inventory to sales, whereas the inventory turnover ratio shows the number of times inventory is sold and then replaced in a specific time period. This ratio is also known as Inventory turnover days, Days sales in inventory, etc. Thus from the above calculations, it has been found that the Business scenario is more or less in the same state. The rising inventory level suggests that there has been an increase in demand for the products but the efficiency of the business has been at the same level.

The variation could be because of differences in supply chain operations, products sold, or customer buying behavior. The more liquid the business is, the higher the cash flows and returns will be. Management is also interested in the company’s days sales in inventory to determine how fast inventory moves, which is important when taking storage and maintenance expenses of holding inventory into account.

How Change in Inventory Impacts Free Cash Flow (FCF)

Essentially, it measures how efficiently a company can turn the average inventory it has into sales. A low DII is a sign a company has a healthy cash flow, while a high DII can signal the company’s cash flow is slow. The days sales in inventory metric can give brands critical insight into how long it takes to sell through their inventory and discover ways to optimize their inventory management process.

The interested parties would want to know if a business’s sales performance is outstanding; therefore, through this measurement, they can easily identify such. But if the DSIs are different, it doesn’t necessarily mean one company’s inventory management is any less efficient than the other. The variation could be because of differences in supply chain operations, products sold, or customer buying behaviour. Demand forecasting can help brands stay ahead of trends—such as seasonal demand for certain products—and allow them to plan ahead to have extra stock on hand. To effectively increase profits and mitigate unnecessary costs, brands need to improve demand forecasting and optimize their supply chains.

Indications of Low and High DSI

While there is not necessarily one perfect DSI, companies typically try to keep low days sales in inventory. A lower DSI indicates that inventory is selling more quickly, which is usually more profitable than the alternative. Irrespective of the single-value figure indicated by DSI, the company management should find a mutually beneficial balance between optimal inventory levels and market demand.

What Is Days Sales of Inventory (DSI)?

However, a high DSI could also mean that the company’s management maybe has decided to maintain high inventory levels to achieve high order fulfillment rates. In this article, we will discuss the importance of days sales in inventories, how to calculate them and provide examples of using DSI in a business. A company could post financial results that indicate low days in inventory, but only because it has sold off a large amount of inventory at a discount, or has written off some inventory as obsolete.

Days Sales of Inventory (DSI): Definition, Formula, Importance

So for example say you started with $200,000 in a given period and ended with $150,000. If you decide to use that method, remember that your ending inventory might not be representative of other points of the year, especially if you experience seasonal fluctuations. To get an even more accurate average inventory you could also take more data points throughout the given time period and simply divide by the number of data points you choose. While DII is useful for helping you get a broad picture of your company’s inventory management, it’s only part of the story. While it’s true that a lower DII is typically better, there are plenty of situations in which a business may make a choice that increases its DII.

So, a low days sales of inventory ratio means a high turnover (because you can sell more times in a given period if each sale takes fewer days). The inventory days metric, otherwise known as days inventory outstanding (DIO), counts the number of days on average it takes for a company to convert its inventory on hand into revenue. The days sales of inventory (DSI) is a financial ratio that indicates the average time in days that a company takes to turn its inventory, including goods that are a work in progress, into sales. Finding the days in inventory for your business will show you the average number of days it takes to sell your inventory. The lower the number you calculate, the better return on your assets you’re getting. Calculating days in inventory is actually pretty straightforward, and we’ll walk you through it step-by-step below.

And when comparing yourself to others in the industry, there’s always the potential for dishonesty. A business could easily report a low DSI, but not declare it was because a large amount of stock was discounted – resulting in quick sales – or even written off. For example, a supermarket will have a low DSI for most products because they are perishable – hence the name FMCG, fast moving consumer goods. More commonly, though, the more days you have inventory, the more likely you will lose money on it, negatively impacting your overall ROI, as well as prospective investors and creditors.
