Conclusively, the days’ inventory outstanding encapsulates critical aspects of a company’s inventory management practices and overall business performance. We’ll assume the average inventory days of our company’s industry peer group is 30 days, which we’ll set as our final year assumption in 2027. The average inventory balance is thereby used to fix the timing misalignment. An Inventory Management System provides real-time insights into stock levels, inventory turnover ratio rates, and demand patterns—crucial for reducing DIO.
Everything You Need To Master Financial Modeling
If a company maintains a healthy DIO, it shows an impressive operating efficiency and good credit terms with its suppliers and vendors. The first step is to calculate the average inventory figure that is the numerator of the DOI formula. Average inventory can be calculated by adding the beginning and ending inventory figure and dividing the sum by two. A step-by-step calculation of days inventory outstanding is an easy approach that offers accurate figures and detailed analysis. A comparative benchmarking analysis of a company’s inventory turnover and DIO relative to its industry peers provides useful insights into how well inventory is being managed. The days inventory outstanding indicator, or DIO, is a key financial indicator that provides insights into this question.
- For instance, Company A could be in the business of selling furniture while Company B manufactures ships and the duration of manufacture is 180 days alone.
- It means the average inventory figure can fluctuate during the accounting period.
- Usually, the shorter the cash conversion cycle the better it is for a business.
- The point is, business operations in different industries vary, and to get a valid interpretation, you need to compare businesses in the same industry.
- Days Inventory Outstanding (DIO) represents a critical financial metric that measures the average number of days a company holds inventory before selling it.
Deciphering the secrets of days inventory outstanding (DIO) can feel like a quest for the Holy Grail. When operations improve, financial performance is often bolstered as a result. If they’re not important to your business, transferring the focus from these laggards to more high-demand, cost-effective products can greatly improve DIO and revenue over time. Going lean in business means trimming the fat from wasteful activities. A lean business can operate effectively and efficiently while holding very little stock, which minimises the total costs of your inventory.
Companies that master this aspect of financial management position themselves for sustainable success regardless of market conditions. The most successful organizations view DIO optimization as an ongoing process rather than a one-time initiative. This approach requires regular monitoring, cross-functional collaboration, and a willingness to challenge established practices. These systems automate inventory calculations, provide alerts for potential issues, and offer analytical tools for continuous improvement. Each of these approaches can reduce the need for buffer inventory while maintaining service levels.
Having good days of inventory levels will vary based on the company size, the industry, and other factors. And a great way to lower it is to start automating your inventory management and online marketplace presence with software like BlueCart.

COGS is the entire cost of acquiring or producing the products sold during a specific period. By multiplying the ratio of inventory value (a valuation from inventory costing methods) to COGS, we see the number of days it typically takes to clear on-hand inventory.
Calculate Days Inventory Outstanding (DIO)
Below is a break down of subject weightings in the FMVA® financial analyst program. As you can see there is a heavy focus on financial modeling, finance, Excel, business valuation, budgeting/forecasting, PowerPoint presentations, accounting and business strategy. The switch toggle in the top right corner cycles between the two methods to forecast the inventory balance.

- So if a company wants to find out whether its DIO value is OK, it should look at the values of other companies in the sector and compare itself with them.
- Generally, a quicker DIO also means a company has an efficient operating capacity.
- Therefore the above are some important differences between the two concepts.
How to Calculate Days Inventory Outstanding
John’s Pharmacy wants to calculate its DIO for the last financial year. The beginning inventory value was $100,000 and the ending inventory value was $200,000. This means the average inventory value for John’s Pharmacy is $150,000. Where a company has a low DIO, it means it is converting its inventory into sales speedily. It also implies that working capital can be diverted for other pending purposes or even used to repay outstanding debt. DIO is affected by how quickly stock arrives and how efficiently it is replenished.
If stock isn’t rotated correctly, older inventory sits longer, increasing Days Inventory Outstanding. First In, First Out (FIFO) and First Expiry, First Out (FEFO) methods prevent stagnation.

For example, include only direct labor, direct material, and other direct inventory costs. Access and download collection of free Templates to help power your productivity and performance.
Formula for Calculating Average Days Inventory Outstanding Ratio
That means we can easily say that day sales of inventory are one of the cash conversion cycle stages, which translates raw materials into cash. Another name of “days inventory outstanding (DIO)” is “days sales of inventory (DSI).” Most companies use an annual period and use 365 days in the DIO formula. Cost of sales or cost of goods sold can be calculated by using the beginning inventory figure. Also, a company must use the relevant cost of goods sold that directly relate to the inventory costs. For clarity, a company can separate labor and overhead costs from the inventory costs to get accurate inventory figures.
This approach provides expert financial guidance specifically when needed, allowing businesses to access senior-level expertise without the commitment of a full-time executive.

While seemingly straightforward, DIO analysis reveals complex operational dynamics that extend beyond the warehouse to impact multiple business functions. Inventory management software like Unleashed can automatically calculate DIO for a business and create reports for comparing average DIO between different products, accounting periods, and more. Days Inventory Outstanding (DIO) is a liquidity metric which measures the average number of days inventory is held in a business before it is sold. DIO can also be used to assess how well a product is selling and what the inventory efficiency is in general.
DIO is therefore important in liquidity management because the less capital is tied up in inventory, the more cash the company has available. To have a point of reference to base our operating assumptions upon, our first step is to calculate the historical inventory days in the historical periods (2020 to 2022). For example, a company that is anticipating a significant increase in demand may choose to maintain higher levels of inventory. The demand for some products also fluctuates seasonally and this translates into the DIO being high during the off-season periods. As earlier indicated, what is considered a good or bad DIO may vary from industry to industry. Regardless, a low day’s inventory outstanding is generally accepted as an indication that a company is able to quickly turn its inventory into sales.
As always, it is essential to remember to be consistent when using periods to calculate DIO. Multiply by 365 days for yearly data; for quarterly data, use 91.25 days; and for monthly analysis, always use 30.4. This means Company A takes approximately 91 days to sell its inventory. Average inventory represents the typical value of inventory maintained during a specific period. This component of DIO reflects the company’s inventory holding patterns and serves as the numerator in the DIO formula.
Let’s analyze the day’s inventory outstanding example data below using ChartExpo. These improvements reduce work-in-process inventory and enable more responsive manufacturing. Leading companies continuously benchmark their DIO against competitors and industry standards to maintain operational excellence. Many financial analysts consider DIO trends when evaluating management effectiveness and business sustainability.
So, this business holds inventory for an average number of 73 days before selling it. In addition to inventory days, there are other important financial ratios that you might be interested in.

In this example, it takes Company XYZ approximately 91.25 days, on average, to sell its inventory.
Usually, the shorter the cash conversion cycle the better it is for a business. The Days Inventory Outstanding (DIO) is the number of days it takes on average before a company needs to replace its inventory. Visual management through well-designed dashboards helps maintain focus on inventory performance. Analyzing DIO alongside other metrics like gross margin return on investment (GMROI) and sell-through rates provides a more comprehensive picture of inventory performance.
Both DIO and DSO are critical for assessing overall cash flow and efficiency average days inventory outstanding formula in managing inventory and receivables. Factors that can affect days inventory outstanding include sales trends, inventory management practices, production schedules, and seasonal fluctuations in demand. Effective DIO management requires a combination of accurate measurement, thoughtful analysis, and strategic action.
