The Ideal Inventory Turnover Ratio for Your Business Goals
The answer to the question, "What is a good inventory turnover ratio?" is the midpoint between two extremes. You don't want your merchandise gathering dust; however, you don't want to have to restock too often. The golden ratio is somewhere in between.
In this article, we'll discuss how to find the ideal turnover ratio considering your industry and size and share practical tactics for reaching that goal.
Your inventory turnover ratio (ITR) is the number of times you sell all your inventory over a year. You can calculate it using the turnover ratio formula:
Cost of goods sold (COGS) / average inventory value.
So, if your COGS for 2019 totaled $300,000 and your inventory was worth $60,000, your ITR would be 5.
We will help you interpret that number and target the optimal inventory level for your business and industry.
What Is a Good Inventory Turnover Ratio?
Some organizations, such as ReadyRatios, track the median ITR in various industries. But while those numbers are good to know, your industry's average ITR isn't necessarily a good inventory turnover ratio for your business.
For most industries, a good inventory turnover ratio is between 5 and 10. This ratio indicates you sell and restock your inventory every 1-2 months.
Optimizing inventory turnover is one of the most critical parts of inventory control. You'll want to look a bit deeper into inventory turnover differences based on industry, the size of the business, and other factors.
Differences in Inventory Turnover by Industry
The industry influences what the ideal inventory turnover ratio will be because of the nature of the products and markets available. Here are a few circumstances in which your industry can affect your optimal ITR:
Low-margin industries, such as grocery stores and discount retailers, need to maintain high turnover to sustain a profit. In general, moving inventory as quickly as possible is the most efficient path for low-margin companies.
Industries with an exceptionally high holding cost, such as the automobile and consumer electronics industries, need to sustain a higher turnover ratio. That's because holding onto goods in these highly competitive, rapidly evolving areas can be exceptionally costly.
Luxury industries, including the jewelry industry, tend to see a high-profit margin with low turnover. That's natural because of the niche markets in which these industries operate.
That said, companies within the same industry can also vary in their turnover rates. Inefficient supply chains and other operational inefficiencies can lead to stagnant inventory. In other cases, it's a matter of scale. For example, a local business offering the same products as a national franchise might sell a lower volume of products less quickly.
Can an Inventory Ratio Be Too High?
In a word, yes. Contrary to some inventory management myths, extremely high turnover can be a bad thing.
If you're continually restocking inventory right as you're running out of it, your inventory levels could get dangerously low. The slightest hitch in your supply chain can lead to a shortage, which means you might not be able to meet customer demand.
Also, a company might have an ultra-high ITR while going bankrupt because the company isn't making enough profit on each sale. Although it's usually not a good idea to sacrifice profit for turnover, it's sometimes necessary—for example, when it's more costly to store "dead stock" in your warehouse than sell it off quickly.
The good news is that a high inventory turnover ratio can be a good thing. There's usually a simple fix: adjust your ordering cycle to better match demand.
The Ideal Inventory Turnover Ratio
The ideal ITR for your business depends on the size of your operation, how quickly you can liquidate your assets, and which products you're selling. When you're just getting your feet wet, you can use the average ITR in your industry as a benchmark.
Over time, though, you'll want to move past industry averages to maximize your company's profits. Sorry, there's no silver bullet for this — you need to dive into your data to find out what's best for your profitability and growth.
The old-fashioned approach involves running calculations in spreadsheets. What many businesses have found, though, is that spreadsheets are better for displaying data than harvesting insights.
Today, you can use software to track your inventory and automate the calculation of your ITR and other vital metrics. Using software will allow you to track your ITR against your profits and discover the healthiest ratio for your business.
With the right software, you'll also be able to find cost-saving opportunities that would otherwise lie dormant in your data.
Solutions for Improving Inventory Turnover
If you've found that your turnover rate is too low, several tried-and-true approaches are worth exploring right off the bat.
"Bundling is a rather easy way of putting new product offerings together to complement the product line. There's more potential to get it right than to get it wrong." - Vineet Kumar, professor at Harvard Business School
Product bundles are a way to harness a simple fact: People are often willing to buy related products together. It seems like such a basic idea, but it's powerful. Almost every business has opportunities to bundle products. That means every company can offer a pathway for consumers to help them clear out a chunk of the inventory at once.
While there's more potential to get it right than to get it wrong as Professor Kumar said, it's best to take a quantitative, data-driven approach to a product bundling strategy. For example, the data suggests that it's not a good idea to offer a bundle without also offering the option to buy each product individually.
Order management systems, including Skubana, equip brands to develop and offer the right product bundles at the right price to increase both turnover and profit.
Changes to Marketing and Promotions
Promotions and discounts are a quick way to turn specific items and increase sales overall. Customers love them, and you can also use discounts to incentivize referrals.
A well-executed marketing campaign can also do great things for inventory turnover. Some tools, such as Bold Upsell, can get more products in front of customers through upselling and cross-selling. For example, Bold Upsell can offer customers shoelaces that go with the shoes in their cart, but it can also suggest a more premium pair of shoes in a compatible or similar style.
Capitalizing on seasonality is another way to craft a marketing strategy to increase your inventory turnover rate. We recommend observing customers' existing purchasing patterns to determine natural seasonality. Include the relative seasonal performance of different sales channels as you examine these trends. That way, you can drive quicker sales with targeted promotions that ride your existing waves.
Ecommerce has made it easy to compare prices from multiple sellers, and shoppers take advantage of that opportunity before they buy. Fortunately, the web has also made it easier for sellers to adjust their prices in real-time to undercut competitors by a small margin.
For example, Repricer.com offers a tool that automatically re-prices your Amazon listings according to flexible rules that you control. Repricer.com reacts to competitors' changes within 90 seconds, eliminating the need to adjust prices manually.
More broadly, it can be smart to review your pricing strategy. This doesn't necessarily mean reducing prices across the board; lower prices don't always increase turnover. Instead, explore the well-established pricing strategies that you may not have considered, such as premium pricing, seasonal pricing, rush delivery, cost-plus pricing, etc.
Improving Inventory Replenishment
Sometimes, your ordering cycle* is the culprit. Fortunately, if you have your historical data, this is a simple problem to fix. There are automated tools that will reorder inventory for you based on sales data, preventing both overstocking and under-ordering. This process limits excess inventory that's hard to turn over.
*The Order Cycle is the length of time needed before you would use up supply to meet your supplier’s target order requirement.
Skubana includes a feature that creates purchase orders automatically (we call it auto-POS) for real-time inventory upkeep. Based on sales velocity data, the inventory optimization software recommends when and how many units of a product to order.
Reviewing Product Portfolio
Above all, to improve inventory turn, you want to stock what sells. Determining profitability by SKU is critical. Many companies get so caught up in increasing revenue that they compromise profits. If the time for a single SKU to turn over is too long, then it's draining your resources, even if it eventually sells.
It's amazing how many business owners don't know which SKUs are generating profit. The first step is to calculate your inventory turnover by individual SKU. Don't do this manually, especially if you have thousands of SKUs; you can automate this process with inventory optimization software.
Bottom Line: Find Your Sweet Spot and Move Toward It
Now that you have some ballpark numbers and you know the kinds of factors that affect ideal inventory turnover, it's time to find the perfect turnover rate for your business. When determining your goal ITR, consider your profit margins; the lower the margin, the faster you need to turn your stock. Also, consider the seasonality of your products and examine the profitability of each SKU.
If you're off target, consider incorporating the supply chain and customer-facing solutions we recommended for your business. You won't reach your ideal ratio overnight. Still, with reliable processes in place and a long-term inventory management strategy, you'll be able to strike that balance sooner than you think.
