1. What is Average Days In Inventory?

Average Days In Inventory is a financial metric that measures how long it takes for a company to turn its inventory into sales. It indicates the efficiency of inventory management and how quickly products are moving through the supply chain.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Days = \frac{(Beg + End\ Inv)}{2} \div \frac{COGS}{365} \]

Where:

\( Beg\ Inv \) — Beginning inventory value in USD
\( End\ Inv \) — Ending inventory value in USD
\( COGS \) — Cost of Goods Sold in USD

Explanation: The formula calculates the average inventory value, then divides it by the average daily cost of goods sold to determine how many days inventory typically remains in stock before being sold.

3. Importance of Inventory Days Calculation

Details: This metric is crucial for businesses to optimize inventory levels, improve cash flow, reduce holding costs, and identify potential issues with product demand or supply chain efficiency.

4. Using the Calculator

Tips: Enter beginning and ending inventory values in USD, along with the annual cost of goods sold. All values must be positive numbers, with COGS greater than zero.
