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.

Inventory Days Formula

A low DSI indicates that a business can effectively turn its stocks into sales. Since a company’s margins and bottom line are seen to benefit from this, a lower DSI is desired over a greater one. On the other hand, a very low DSI may suggest that a business is not meeting demand with its inventory stock, which might be considered subpar. The kind of product, company strategy, and time needed for replenishment are a few variables that impact how long it takes to sell inventory. When predicting client demand, scheduling inventory replenishment, and estimating the lifespan of an inventory lot, DSI is a helpful statistic. By calculating DSI, you may get a baseline for the average time it takes to sell all of your inventory.

Investing in a powerful forecasting tool can help you control your inventory size in relation to your rate of sales. You can find data for your average inventory and COGS on your annual financial statements. If you sell through Shopify, you can find your COGS in your inventory reports.

A financial ratio called days sales of inventory (DSI) shows how long it typically takes a business to sell the products in its inventory. Since DSI indicates the duration of time a company’s cash is tied up in its inventory, a smaller value of DSI is preferred. A smaller number indicates that a company is more efficiently and frequently selling off its inventory, which means rapid turnover leading to the potential for higher profits (assuming that sales are being made in profit). On the other hand, a large DSI value indicates that the company may be struggling with obsolete, high-volume inventory and may have invested too much into the same. It is also possible that the company may be retaining high inventory levels in order to achieve high order fulfillment rates, such as in anticipation of bumper sales during an upcoming holiday season.
