Days Sales in Inventory: Formula + Best Practices

how to calculate days sales in inventory

By calculating the number of days that a company holds onto the inventory before it is able to sell it, this efficiency ratio measures the average length of time that a company’s cash is locked up in the inventory. Some retailers may employ open-to-buy purchase budgeting or inventory management software to ensure that they’re stocking enough to maximize sales without wasting capital or taking unnecessary risks. 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.

What Is a Good Inventory Turnover?

While COGS is a line item found on the income statement, the inventory line item is found in the current assets section of the balance sheet. In effect, there is a timing mismatch as the income statement measures performance across a period, but the balance sheet is a “snapshot” of a company’s assets, liabilities, and shareholder’s equity at a specific point in time. In conclusion, we can see how Broadcom has continuously reduced its inventory days compared to Skyworks, which has just only increased in the last five years.

Inventory Days

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. DSI is also known as the average age of inventory, days inventory outstanding (DIO), days in inventory (DII), days sales in inventory, or days inventory and is interpreted in multiple ways. 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. Essentially, sales in inventory can look into how long the entire inventory a company has will last.

The other two stages are days sales outstanding (DSO) and days payable outstanding (DPO).

If a company’s DSI is on the lower end, it is converting inventory into sales more quickly than its peers. Moreover, a low DSI indicates that purchases of inventory and the management of orders have been executed efficiently.
