Days Sales of Inventory DSI: Definition, Formula, Importance
The Days Sales in Inventory (DSI) value gives an estimation of the time required for a business to turn its inventory into sales. Generally, a low DSI is preferred because it denotes quick inventory turnovers, although the ideal DSI will vary depending on the organization and its sector. This gives you the information you need to calculate and monitor DSI, as well as other critical metrics such as inventory turnover, COGS, and average inventory valuation. 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.

Order Cycle Time: What Is It, How to Measure & Improve It
Indicating the liquidity of the inventory, the figure represents how many days a company’s current stock of inventory will last. Generally, a lower DSI is preferred as it indicates a shorter duration to clear off the inventory, though the average DSI varies from one industry to another. Generally, a small average of days sales, or low days sales in inventory, indicates that a business is efficient, both in terms of sales performance and inventory management. A low DSI reflects fast sales of inventory stocks and thus would minimize handling costs, as well as increase cash flow.
Essentially, sales in inventory can look into how long the entire inventory a company has will last. It’s critical information for management to understand, as well, so they can monitor the rate of inventory turnover and inventory levels. Plus, analyzing these details can help prevent theft of obsolescence, increase cash flow, and reduce costs. A retail corporation, such as an apparel company, is a good example of a company that uses the sales of inventory ratio to determine the cost of inventory. 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.
Formula for Days Sales Inventory (DSI)
As well, this ratio can be important to plan for future demand, such as market demand and customer demand. This is because the final figure that’s determined can show the overall liquidity of a business. Investors and creditors want to know more about the business sales performance. The more liquid a company is, it will likely translate into having higher cash flows and bigger returns. The figure that you end up with helps indicate the liquidity of inventory management and highlights how many days the current inventory a company has will last. Typically, having a lower DSI is going to be preferred since it means it will take a shorter amount of time to clear inventory.
Generally, low DSI values are preferred since it indicates the smart conversion of inventories. Ideally, a good DSI is 30–60 days (depending on the entity’s size and industry). The average number of days to sell inventory really varies from business to business depending on the operating model, items being sold, the transit time, etc. ShipBob helps ecommerce companies manage inventory so that they can meet the increasing consumer demand without slowing down.

Inventory Turnover Days
Leveraging the information that these ratios provide allows you to make more informed decisions in the future. 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. A very low DSI, however, can indicate that a company does not have enough inventory stock to meet demand, which could be viewed as suboptimal. 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. You’ll walk away with a firm understanding of what inventory days is, why it’s an inventory management KPI you must pay attention to, and how to calculate ending inventory.
Why the DSI Matters
Days sales in inventory is also one of the measures used to determine the cash conversion cycle, which is the company’s average days to convert resources into cash flows. On the other hand, if the inventory turnover ratio is low, it indicates the company’s goods are slow to move or are not getting sold much in the market. As a result, it means higher holding costs, possible outdating of goods held, and naturally lowers profits. On the other hand, DSI shows the time frame the business can turn its inventory into sales. Therefore, inventory turnover and days sales in inventory concepts are related.

This is often important information that investors and creditors find valuable, and the company size doesn’t usually matter. In the second version, the average value of end-date inventory as well as start-date inventory is considered. The resulting figure would then represent the DSI value that occurs during that specific time period. A retail company is an example of a business that would use days sales inventory.
One must also note that a high DSI value may be preferred at times depending on the market dynamics. However, this number should be looked upon cautiously as it often lacks context. DSI tends to vary greatly among industries depending on various factors like product type and business model. Therefore, it is important to compare the value among the same sector peer companies. Companies in the self employment tax in seattle, washington technology, automobile, and furniture sectors can afford to hold on to their inventories for long, but those in the business of perishable or fast-moving consumer goods (FMCG) cannot.
The inventory that’s considered in days sales the historical cost principle and business accounting in inventory calculations is work in process inventory and finished goods inventory (see what is inventory). Days sales in Inventory (DSI) exhibits the average number of days a business requires to clear the inventory by selling it. So finding the average days sales in inventory is one way to measure inventory management. Generally, a decrease in DSI indicates an improvement in working capital, whereas an increase in DSI denotes a decline. On the other hand, a high DSI shows that the company has had trouble converting its inventory into revenues. However, the days sales in inventory is a metric that is also considered by investors, as it is part of the cash conversion cycle (CCC).
COGS is the entire cost of acquiring or producing the products sold during a specific period. By multiplying the ratio of inventory value (a valuation from inventory costing methods) to COGS, we see the number of days it typically takes to clear on-hand inventory. To use the inventory days formula, you need both your average inventory formula and your cost of goods sold, or COGS. For the year-end 2015 financial statements, Target Corp. reported an ending inventory of $1M and a cost of sales of $100M. Given the figures, the DSI for the year is 3.65 days, meaning it takes approximately 4 days for the company to sell its stock of inventory.
