1. What is Days Inventory On Hand (DIO)?

Days Inventory On Hand (DIO) is a financial metric that measures the average number of days a company holds its inventory before selling it. It indicates how efficiently a company manages its inventory and provides insight into inventory turnover and cash flow management.

2. How Does the Calculator Work?

The calculator uses the DIO formula:

\[ DIO = \frac{\text{Average Inventory}}{\text{Cost of Goods Sold}} \times 365 \]

Where:

\( DIO \) — Days Inventory On Hand (days)
\( \text{Average Inventory} \) — Average inventory value over a period (currency)
\( \text{COGS} \) — Cost of Goods Sold for the period (currency/year)
\( 365 \) — Number of days in a year

Explanation: The formula calculates how many days it takes for a company to turn its inventory into sales. A lower DIO indicates more efficient inventory management.

3. Importance of DIO Calculation

Details: DIO is crucial for assessing inventory management efficiency, identifying potential cash flow issues, comparing performance with industry benchmarks, and making informed purchasing and production decisions.

4. Using the Calculator

Tips: Enter average inventory in currency units, COGS in currency per year. Both values must be positive numbers. The calculator will compute the number of days inventory remains on hand.

5. Frequently Asked Questions (FAQ)

Q1: What is a good DIO value?
A: Ideal DIO varies by industry. Generally, lower values are better, but it should be compared with industry averages. Retail typically has lower DIO than manufacturing.

Q2: How is average inventory calculated?
A: Average inventory = (Beginning Inventory + Ending Inventory) ÷ 2, usually calculated for a specific period (monthly, quarterly, or annually).

Q3: What does a high DIO indicate?
A: High DIO may indicate slow-moving inventory, overstocking, obsolete products, or poor sales performance, which can tie up working capital.

Q4: How does DIO differ from inventory turnover?
A: Inventory turnover measures how many times inventory is sold and replaced, while DIO converts this to days. DIO = 365 ÷ Inventory Turnover.

Q5: Can DIO be too low?
A: Yes, extremely low DIO may indicate stockouts, lost sales opportunities, or insufficient inventory to meet customer demand, potentially harming customer satisfaction.
