A financial ratio called days sales of inventory (DSI) shows how long it typically takes a business to sell the products in its inventory. To calculate days in inventory, you need data from your financial statements – cost of goods sold and average inventory value. We’ll explain how to determine these figures and do the calculation in the next sections. Inventory Days, also known as Days Sales of Inventory (DSI) or Days Inventory Outstanding (DIO), indicates the average time (in days) that a how long company takes to sell its inventory. This metric provides insights into inventory management efficiency and the liquidity of inventory assets.
These businesses generally have lower DSIs due to high inventory turnover and consistent demand. This means it takes your business, on average, 73 days to sell its entire inventory. A healthy DSI means your products are moving, cash flow is positive, and your warehouse isn’t overflowing with unsold stock.
In the formula inventory includes the total of raw materials, work in process, and finished goods that a business holds for the purpose of resale. A higher turnover ratio is ideal as it shows strong demand and inventory efficiency. Measures how many times inventory is sold and replaced in a given period. This involves taking beginning inventory, adding new purchases, and subtracting ending inventory. However, the projected inventory balances are equivalent under both approaches, as confirmed by our completed model. The switch toggle in the top right corner cycles between the two methods to forecast the inventory balance.

- Manually tracking your DSI on your own by using the number of days sales in inventory formula is a great start.
- This method is particularly beneficial for businesses prioritising high turnover rates.
- 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.
As well, this ratio can be important to plan for future demand, such as market demand and customer demand. There are two different versions of the DSI formula that can be used, and it depends on the accounting practices of the company. In the first version, the average amount of inventory is reported based on the end of the accounting period. Dig into patterns, seasonality, and trends to anticipate future demand for different products. Complex productsLengthy production times, specialized components, or supply chain disruptions can lead to higher DSIs. The inventory days calculator is available for download in Excel format by following the link below.
The denominator, on the other hand, will represent the average per day cost. This is how much the company would spend to manufacture the salable product. In order to manufacture a product that’s sellable, companies need to acquire raw materials as well as other resources.

Moreover, DOI can also be used to express how long it takes the company to sell its inventory of finished goods. Then, calculate the average inventory level and COGS using the AVERAGE and SUM functions, respectively. The DATEDIF function in Excel calculates the difference between two dates in a specified interval, such as days, months, or years. For example, costs can include the likes of labor costs and utilities, such as electricity. Ultimately, they’re defined as the costs incurred to acquire or manufacture any products that are created to sell throughout a specific period. DOH measures the number of days inventory remains in stock—or on hand.
Example of DSI
So if beginning inventory was $100,000, plus purchases of $150,000, minus ending inventory of $60,000, the COGS would be $190,000. ❌ Failing to update the cost of goods sold (COGS) can lead to outdated calculations. ❌ Using the selling price instead of the cost price skews the calculation.
Here are two alternative approaches based on average inventory and inventory turnover. This result indicates that, on average, the company’s inventory is held for 91.25 days before being sold, offering insight into stock movement efficiency and potential areas for improvement. Next, the company’s days inventory outstanding (DIO) can be calculated by dividing the $20mm in inventory by the $100mm in COGS and multiplying that by 365 days – which results in 73 days. The formula to calculate days inventory outstanding (DIO) consists of dividing the average (or ending) inventory balance by cost of goods sold (COGS) and multiplying by 365 days.
