Days Sales of Inventory (DSI) is a financial metric that measures the average number of days it takes a company to sell its inventory. It is calculated by dividing the total inventory by the average daily sales.
DSI is an important metric for businesses because it can help to assess their liquidity and financial health. A high DSI can indicate that a company is struggling to sell its inventory, which can lead to cash flow problems. However, a low DSI can indicate that a company is managing its inventory well and that it is generating cash flow from its sales.
The ideal days sales of inventory for a company will vary depending on its industry and its specific circumstances. However, a general rule of thumb is that a DSI of 30-60 days is considered to be healthy.

Some examples of Days Sales Of Inventory for different industries are:
- Retail: 30-60 days
- Manufacturing: 60-90 days
- Pharmaceuticals: 90-120 days
- Mining: 120-180 days
Here is the formula for calculating DSI:
DSI = (Inventory / Average Daily Sales) * 365
For example, if a company has $100,000 in inventory and an average daily sales of $2,000, its DSI would be 182.5 days.
Frequently Asked Questions
What does it mean when a days sales of inventory increases?
An increase in DSI means that the company is taking longer to sell its inventory, which may have several implications. Some possible reasons for a high DSI are:
- The company is experiencing a decline in sales due to economic or competitive factors, which reduces the demand for its products and leaves more inventory unsold.
- The company is overstocking its inventory, either because of poor forecasting, inefficient inventory management, or strategic reasons (such as anticipating future price increases or customer demand).
- The company is selling products that have a long production cycle, a seasonal demand, or a high degree of customization, which requires more time and resources to complete and deliver.

Is a higher days sales of inventory good?
No, a higher days sales of inventory (DSI) is not necessarily good. A higher DSI can indicate that a company is holding too much inventory, which can have a number of negative consequences for the business.
What is a good inventory turnover ratio?
A good inventory turnover ratio depends on the industry, the type of products, and the market conditions. Different industries have different inventory cycles and demand patterns, so there is no universal benchmark for a good ratio.
For example, according to some industry averages reported by CSIMarket in 2023, the inventory turnover ratio for grocery stores was 14.8, while for computer hardware companies, it was 8.9.
