Best Practices to Optimize Inventory DOH

Calculating days in inventory is actually pretty straightforward, and we’ll walk you through it step-by-step below. 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. If you want to minimize costs within your inventory management system and have the perfect number of products in stock, you’ll want to use economic order quantity forecasting, or EOQ. As a business owner, you need to ensure you have enough funds allocated to inventory management in your yearly budget. Looking at past historical data and pairing it with machine learning can help you make better predictions for your budgets in the next year. As Zalzal told me, inventory forecasting is the foundation for demand forecasting.

• It’s also a commodity that likely won’t see a spike in demand unless something crazy happens, like panic buying because of a global pandemic.
• One reason your company might struggle with low inventory is vendor delivery times.
• Uncover common challenges businesses face when optimizing inventory days.
• This is why they’ll often outsource inventory management to an experienced third-party logistics provider.
• Ultimately, you have to weigh the risk of missed sales opportunities against the increased profit potential to make the best decision for your business.

Step 2: Calculate Cost of Goods Sold

• The best way to reduce inventory days is to take control of your inventory management.
• A higher DSI ties up cash in unsold inventory, affecting liquidity.

• We must remember that typically the cost of storing an item is represented as a percentage of its valuation (in the previous example, 24%).
• This means that, on average, it will take your business 82 days to sell the inventory you have on hand.

Once I place my order, it takes 15 days to receive the bottles, and I typically sell five water bottles a day. Let’s compare high and low ratio turnover rates to see what they might indicate about the efficiency of your inventory strategy. For example, during the Holiday season, retailers tend to see spikes in demand as people shop for gifts. To prepare for this, you use year-over-year sales data to forecast the demand increase you can expect to see. You conclude that you’ll see an average sales increase of 50% through November and December. Secondly, we need to determine our COGS for the specified period of time.

Businesses aim to balance supply with demand, minimize costs, and maximize profits. A key metric in this domain is Inventory Days, which measures the average number of days a company holds inventory before selling it. Understanding and optimizing this metric can significantly enhance operational efficiency and financial performance. In fact, an increase in efficiency is why 51% of businesses opt to use inventory management software. Business owners who use inventory management tools can better manage their orders. Using these tools, you can get a good idea of when to order or move products, helping you stay more efficient, organized, and on top of product demand.

What does days in inventory measure?

While you won’t necessarily earn your investment back, you can still write it off, and many customers will appreciate your company’s charitable efforts. Finance professionals in distribution businesses face a persistent challenge. That is to effectively blend operational and financial data to gain a complete picture of company performance. Traditional financial ratios often exist in isolation, making it difficult to assess the broader impact of operational decisions on financial outcomes. Overall, having less inventory can also mean lower taxes since some taxes depend on how much stock you have at certain times, like the end of the year.

Reduce Holding Costs

This is considered a fairly high turnover rate, which is a good thing for most businesses. Adaptable, efficient businesses have a few things in common with one another. First, determine the time how to calculate inventory days period you want to calculate days in inventory for. This is usually your accounting period – which could be a month, quarter or year. Uncover common challenges businesses face when optimizing inventory days. Gain valuable insights into overcoming obstacles and streamlining your inventory management processes.

If you sell through Shopify, you can find your COGS in your inventory reports. The cost of goods sold (or COGS) is the cost of products you sold over the course of the year. To calculate COGS for your business, take the cost of your beginning inventory, add any additional inventory purchases you made during the year, and then subtract your ending inventory. A higher turnover ratio is ideal as it shows strong demand and inventory efficiency. The projection of the cost of goods sold (COGS) line item finished, so the next step is to repeat a similar process for our forward-looking inventory days assumptions that’ll drive the forecast.

Investing in a powerful forecasting tool can help you control your inventory size in relation to your rate of sales. Demand is often subject to consumer interests, seasonality, economic trends, and more. By understanding and predicting these fluctuations, you can maintain an inventory size responsive to trends in demand, avoiding unnecessary storage or obsolescence. You can find data for your average inventory and COGS on your annual financial statements.

Inciflo provides real-time visibility of your inventory on hand, helping businesses reduce excess stock and avoid stockouts. Inventory days and inventory turnover are very similar measurements. Inventory turnover shows how fast you sell and replace all your stock. If your inventory days metric is low, your inventory turnover should be high, and vice versa. We can derive the formula for Days in Inventory by including the number of days of the year with the inventory turnover ratio. EOQ models factor in your demand rate, order, and holding costs to help you optimize your inventory.

That is why stocks are your riskiest investment and you never know when they will pay off. Understanding how much time you will spend on selling goods will allow you to minimize it. The number of days for which your power will bring profit is the most accurate indicator. Of course, this number varies by industry—a business in the high-end jewelry industry typically sees slower sales rates (and therefore will have a higher DSI) than a business selling t-shirts.

For example, if you’re stocking up for the holidays or a big promotion, your days on hand will be inflated. However, a general rule of thumb is that the lower your inventory days on hand, the more efficient your cash flow is and, therefore, the more efficient your business. Inventory days help you forecast ideal inventory levels, to uphold sales and maintain cash flow. If your inventory days creep up, it could mean sales are slowing or you’re over-ordering. Lowering your inventory days means you’re getting closer to just-in-time ordering, meaning you hold the stock you need to fulfil orders without tying up too much cash in inventory or storage costs. If you ever want to know about the efficiency of inventory management of a firm, you should look at both – inventory turnover ratio and inventory days.

Zalzal confirmed that security breaches are a big concern for companies since most businesses work with private and sensitive data. However, if those warehouses are hacked, sensitive data can become public information. By applying this metric, you’re able to order enough inventory to address increased demand without overspending. To answer that question, let’s examine some ways we can apply this metric to create an inventory strategy that meets demand without reducing profits excessively. Since the cost of each SKU is $10.00, you can also determine the average inventory value by multiplying 750 x 10, which comes up to $7,500.
