1. What is Days Sales of Inventory (DSI)?

Days Sales of Inventory (DSI), also known as Average Days in Inventory, is a financial ratio that measures the average number of days a company holds its inventory before selling it. It indicates how efficiently a company manages its inventory.

2. How Does the Calculator Work?

The calculator uses the DSI formula:

\[ DSI = \frac{\text{Average Inventory}}{\text{COGS}} \times 365 \]

Where:

$ \text{Average Inventory} $ — Average value of inventory held during the period ($)
$ \text{COGS} $ — Cost of Goods Sold for the year ($/year)
$ 365 $ — Number of days in a year

Explanation: The formula calculates how many days it would take to sell the average inventory based on the current cost of goods sold rate.

3. Importance of DSI Calculation

Details: DSI is crucial for assessing inventory management efficiency. A lower DSI indicates faster inventory turnover and better liquidity, while a higher DSI may suggest overstocking or slow-moving inventory.

4. Using the Calculator

Tips: Enter average inventory in dollars, COGS in dollars per year. Both values must be positive numbers. Average inventory is typically calculated as (Beginning Inventory + Ending Inventory) / 2.

5. Frequently Asked Questions (FAQ)

Q1: What is a good DSI value?
A: Ideal DSI varies by industry. Generally, lower values are better, but compare with industry benchmarks. Retail typically has lower DSI than manufacturing.

Q2: How does DSI differ from inventory turnover?
A: DSI shows days to sell inventory, while inventory turnover shows how many times inventory is sold and replaced annually. DSI = 365 / Inventory Turnover.

Q3: What causes high DSI?
A: High DSI can result from overstocking, poor sales, obsolete inventory, or seasonal fluctuations in demand.

Q4: How can companies improve DSI?
A: Strategies include better demand forecasting, inventory optimization, supplier management, and sales promotion for slow-moving items.

Q5: Are there limitations to DSI?
A: DSI doesn't account for inventory quality, seasonal variations, or industry-specific factors. Should be used with other financial ratios for comprehensive analysis.
