The Days Inventory Outstanding (DIO) is a metric that indicates the average number of days a company holds its inventory before selling it. DIO’s meaning also reveals an organization’s capability to convert stock into revenue. 

Furthermore, this method represents the company’s proficiency in managing inventory and selling products swiftly. It is also known as “Inventory Days of Supply, Days in Inventory, or the Inventory Period.” Enabling efficient bookkeeping services can automate receipt tracking and improve accuracy.

How Do You Calculate the Days Inventory Outstanding (DIO)?

You might be wondering about how to calculate inventory days for your business. Fear not — The methodology is straightforward and crucial for controlling operations smoothly. You just need to apply the Days Inventory Outstanding formula correctly.

The Days in Inventory formula is as follows:

Where:

• Average Inventory: It provides detailed information about a firm’s stock levels. A clear view of COGS often comes from detailed cost accounting analyses.

  Formula to calculate Average Inventory: (Beginning Inventory + Ending Inventory)/2 

• Cost of Goods Sold: It is a report that shows the direct costs incurred in generating revenue from sales.

• Number of Days: The period in the DIO formula is typically 365 days.   

An Example of DIO

Let’s understand the Days Sales in Inventory formula with a simple and quick example. 

For example, XYZ Company has a beginning inventory ($50,000) and an ending inventory ($60,000) with a COGS ($300,000) for the year. Calculate the Days in Inventory formula. 

Solution: Firstly, compute the Average Inventory.

Average Inventory= (Beginning inventory + Ending inventory)/2

                                     ($50,000 + $60,000)/2

                                     $55,000

Now, calculate the Days Inventory Outstanding with the formula.

DIO= (Average Inventory​/COGS)x 365

          ($55,000/$300,000)x 365

          67.17 days

In this instance, the XYZ company takes approximately 67.17 days to sell its products or convert its goods into cash—an approach as straightforward as handling a retro pay adjustment.

Why is a DIO Important for an Organization?

After acknowledging the DIO meaning and its formula, let’s move towards the importance of Days Inventory Outstanding for a business.

Here, I’ve jotted down some reasons why a DIO is beneficial for any company:

1. Inventory Management

One of the key advantages of the DIO formula is that it efficiently regulates and optimizes the company’s inventory system. A low Days Sales in Inventory indicates that products are selling quickly, allowing the business to convert stocks into cash successfully.

As a result, you can save the expense of storage, reduce the chances of voided products, and make profitable funds.    

2. Cash Flow Management

Whether you own a small business or a large company, most of the capital is invested in stocks. That’s why inventory plays a major role in maintaining cash inflow and outflow. 

By mastering the Days Inventory Outstanding formula, you will conveniently minimize the additional cost and maintain cash flow in a statement. This will result in freeing up funds for other investments to make profitable financial sources.

3. Operational Performance

A DIO signifies the financial and operational performance of a business. Therefore, a low DIO means that inventory management and business operations are running smoothly, according to the demand for the product. 

On the other hand, a high DIO suggests that there are some inventory issues, and sales are not up to par to earn profits. 

4. Risk Assessment

Days Inventory Outstanding allows you to detect possible issues in your inventory management, such as falling sales, surplus stock, and issues in the supply chain. 

That’s why you should take preventive measures to reduce the negative impact of cash flow by detecting problems at an early stage. Hence, days sales in inventory aid in reducing risks related to sales and stocks.   

5. Competitive Analysis

By comparing DIO with other companies, you can readily analyze the operational efficiency and success rates of your business. It will help to comprehend the competition in the same industry standards.

Moreover, with the aid of the Days in Inventory formula, you can implement better methods to compete with your rivals. It will assist you in earning maximum profits and increasing revenue.

Difference Between DIO and Inventory Turnover

Many people are baffled between DIO and Inventory Turnover, but the two terms are not the same.

Inventory Turnover is a metric that measures how many times inventory is sold and replaced. Hence, it tells you how inventory levels are restocked at a specific time. While inventory days formula calculates how many days a product is sold to customers.  

Let’s understand with a detailed breakdown of DIO and Inventory Turnover. 

Basis	Daily Inventory Outstanding	Inventory Turnover
Definition	It is a formula that measures the average number of days a company takes to sell its inventory.	It is a financial ratio that shows how many times a company sells and replaces its inventory.
Interpretation	A low DIO indicates that an organization can quickly convert its product into cash.	A higher inventory turnover ratio shows efficient inventory management, and a firm is selling and replacing stock speedily.
Formula	DIO = (Average Inventory/ COGS)*365	Inventory Turnover = COGS/Average Inventory
Example	If a company holds its inventory for an average of 60 days before selling it, then the days’ sales in inventory are 60.	If a company sells and replaces its inventory 5 times a year, then its inventory management is 5.

High DIO Vs. Low DIO: What’s the Difference?

You may wonder how DIO serves as a measurement tool for inventory management. In addition to being an inventory indicator, a low DIO means selling of stocks at a high speed, and a high DIO shows slower inventory turnover and poor sales. 

Take a look at the difference between a high DIO and a low DIO. 

A Low DIO

As a general thumb rule, a low DIO is also termed as good Days Inventory Outstanding. It signifies that an organization is selling its inventory quickly, which is viewed as a favorable condition. 

Moreover, the fastest sales eliminate the chances of obsolete products and increase profits. A low inventory days also represents that working capital is free to be invested in other purposes or used to meet other expenses. 

However, a low DIO also hints that a firm could face some consequences to combat the sudden increase in demand, especially in the case of physical products. 

A High DIO

On the contrary, a high DIO displays the firm’s inefficiency in selling inventory rapidly. If the DIO is high, it means that products are stored for a longer period in the company’s warehouse. It is associated with overstocking, extra storage costs, and a high level of outdated stock that never sells. 

As a result, an organization might encounter insufficient cash flow to meet other expenses. Therefore, a high inventory days reduces a company’s liquidity, as it takes a longer time to convert stock into revenue. 

Besides this, it also depicts the poor sales, which negatively impact the financial health of a business.

As an entrepreneur, if you struggle with a high DIO, you have to monitor potential delays in your business operations. By implementing better anticipation and methods in your organization, you can cover discrepancies for favorable outcomes.

1. Establish Robust Planning

Focusing more on increasing the accuracy of actual figures rather than predicted sales. This will reduce the problem of overstocking. By examining accurate demand, you can save expenditure on irrelevant inventory.
