Adjusting prices to increase the turnover rate can help reduce DSI, thereby improving cash flow and reducing holding costs. 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. Days’ sales in inventory (DSI) indicates the average time required for a company to convert its inventory into sales. However, a large number may also mean that management has decided to maintain high inventory levels in order to achieve high order fulfillment rates.

• The denominator (Cost of Sales / Number of Days) represents the average per day cost being spent by the company for manufacturing a salable product.
• The carrying cost of inventory, which includes rent, insurance, storage costs, and other expenses related to holding inventory, may directly impact profit margin if not managed properly.
• Days’ sales in inventory (DSI) indicates the average time required for a company to convert its inventory into sales.

These businesses should calculate DSI for their peak and off-peak seasons separately to gain accurate insights. Understanding these seasonal variances helps in better inventory planning and ensures that the business is not caught off-guard during high-demand periods. To get this number, companies look at their inventory at the beginning and end of a period, usually a full year, and average these two numbers. This method is great because it smooths out any ups and downs that happen because of seasonal changes or normal business cycles. The days’ sales in inventory figure can be misleading, for the reasons noted below.

Days Sales in Inventory Formula

You just need to look at your inventory levels at the beginning and end of a specific period, which could be a month, a quarter, or a year. To find your average inventory, add these two figures together and divide by two. This average will give you a good estimate of the inventory you had during that period. For instance, luxury car manufacturers may have a higher DSI compared to fast-fashion retailers, similar to how software development timelines differ from rapid app rollouts.

But on its own, DSI allows you to have greater visibility over the inventory in your business, to see whether you have too much on hand, or aren’t carrying enough – which means you’re having to continually reorder. With your DSI, you have a benchmark for your own business and a figure you can use as a comparison to others in your industry.
