Days sales in inventory (DSI) measures how long it takes to convert inventory into sales, calculated as (average inventory/cost of goods sold) x 365. A low DSI is an indicator of a healthy cash flow, while a high DSI can indicate slow cash flow. For a company that sells more goods than services, days sales in inventory is an important indicator for creditors and investors, because it shows the liquidity of a business. The interested parties would want to know if a business’s sales performance is outstanding; therefore, through this measurement, they can easily identify such.

If a company has a low DIO, it is converting its inventory to sales rapidly – meaning working capital can be deployed for other purposes or used to pay down debt.

However, a low DIO might also indicate that the company could struggle to meet a sudden increase in demand.

How is DSI calculated?

An increase in DSI alongside declining turnover may indicate that you are holding excess inventory, particularly of low-priority or slow-moving items.

Moreover, a high DSI signifies minimal risk of obsolescence or spoilage, positively impacting the company’s bottom line days sales in inventory formula and overall profitability.
