Inventory turnover ratio

Stock Turns
Stock turnover is a measure of operational efficiency. Specifically, it tells you how many times stock or inventory is being sold and purchased over a given time period. A low turnover rate may point to overstocking, obsolescence, or deficiencies in the product line or marketing effort. A high turnover rate may indicate inadequate inventory levels, which may lead to a loss in business.
What is the 'Norm' for Stock Turns? It varies by industry and comparisons should only be made against similar industries. For example a supermarket sells fast moving consumer goods so the stock turnover will be higher (say) 50; whereas a white-ware Retailer would have a lower turnover of (say) 6. In manufacturing a reasonable Stock Turn would be 8. You should compare your industry's stock turns against other – similar – industries to determine a realistic value. If that cannot be done then simply improve your own Stock Turns to make it as effective as possible.
Stock Turns are calculated in a variety of ways. However, one of the most common ways is to divide total sales COGS by average inventory value.
The formula therefore is:
cTurnover = Total Cost of Goods Sold / Average Inventory
Where
Average Inventory = (Beginning Stock + End Stock) / 2

  • Run the Inventory Value "As At" based on today minus 365 days
  • Run the Inventory Value "As At" based on today
  • Determine the Average Inventory
  • Determine the COGS over the past 365 days
  • Calculate the Stock Turns.

The inventory turnover ratio measures the number of times inventory has been turned over (sold and replaced) during the year. It is a good indicator of inventory quality (whether the inventory is obsolete or not), efficient buying practices and inventory management. It is calculated by dividing total purchases by average inventory in a given period.
Assessing your inventory turnover is important because gross profit is earned each time such turnover occurs. This ratio can enable you to see where you might improve your buying practices and inventory management. For example, you could analyze your purchasing patterns as well as those of your clients to determine ways to minimize the amount of inventory on hand. You might want to turn some of your obsolete inventory into cash by selling it off at a discount to specific clients. This ratio can also help you see if your levels are too low and if you're missing out on sales opportunities.

Average inventory is the median value of an inventory at a specific time period. It is calculated by adding current inventory and previous inventory, then dividing by two.
The same concept is also used to calculate the average inventory over a full year. That requires summing each month’s inventory and then dividing by 13, which is the number of months in the year plus a base month.
For example, a clothing retailer may require more inventory on hand near the end of a calendar year as the holidays approach.
It totals its inventory for each month, which started at $10,000 in January and climbed to $20,000 in December. It divides by 13 points, including the base month of the current January, and gets an average of $13,153.
If that same retailer wanted to calculate its average inventory for July and August, when back-to-school shoppers were busy, it could add its $14,000 figure for July and its $15,000 for August and divide by two to get $14,500.
Since two points do not always accurately represent changes in inventory, many businesses calculate their average inventory month-to-month for a year plus a base month, providing 13 points. Businesses that see their sales fluctuate by seasons may prefer calculating their average inventory for a solid year to reveal a more accurate picture.

What is 'Inventory Turnover'

Inventory turnover is a ratio showing how many times a company has sold and replaced inventory during a period. The company can then divide the days in the period by the inventory turnover formula to calculate the days it takes to sell the inventory on hand. It is calculated as sales divided by average inventory.

BREAKING DOWN 'Inventory Turnover'

Inventory turnover measures how fast a company sells inventory and analysts compare it to industry averages. Low turnover implies weak sales and, excess inventory. A high ratio implies either strong sales or large discounts.
The speed with which a company can sell inventory is a critical measure of business performance. It is also one component in the calculation of return on assets — the other component is profitability. The return a company makes on its assets is a function of how fast it sells inventory at a profit. High turnover means nothing unless the company is making a profit on each sale.

Inventory Turnover Example

Companies calculate inventory turnover as sales divided by average inventory. One can calculate average inventory as: (beginning inventory + ending inventory)/2. Using average inventory accounts for any seasonality effects on the ratio. Inventory turnover is also calculated using the cost of goods sold, which is the total cost of inventory. Analysts divide COGS by average inventory instead of sales for greater accuracy in the inventory turnover calculation because sales include a markup over cost. Dividing sales by average inventory inflates inventory turnover.

Approach 1: Sales Divided By Average Inventory

As an example, assume company A has $1 million in sales and $250,000 in COGS. The average inventory is $25,000. Using the first equation, the company has an inventory turnover of $1 million divided by $25,000 in average inventory, which equals 40 turns per year. Translate this into days by dividing 365 by inventory turns. The answer is 9.125 days. This means under the first approach, inventory turns 40 times a year and is on hand approximately nine days.

Approach 2: COGS Divided By Average Inventory

Using the second approach, inventory turnover is calculated as the cost of goods sold divided by average inventory, which in this example is $250,000 divided by $25,000, which equals 10. You can then calculate the number of inventory days by dividing 365 by 10, which is 36.5. Using the second approach, inventory turns over 10 times a year and is on hand for approximately 36 days.
The second approach gives a more accurate measure because it does not include markup. Only compare inventory turnover that uses the same approach for an apples-to-apples comparison.

Managing inventory is very important in a company that sells products to make a profit. Calculating inventory days is an indicator of how well the business is doing in terms of inventory. With this information, you can compare your business's inventory days with that of your competitors. A lower inventory days measurement means that you are achieving higher inventory turnover and a better return on assets. Calculating inventory days involves determining the cost of goods sold and average inventory in a given period. To calculate the days in inventory, you first must calculate the inventory turnover ratio, which comprises the cost of goods sold and the average inventory. Then, you'll need to divide the number of days in the period by this inventory turnover ratio to determine days in inventory.
Learn the definition of inventory turnover ratio. Inventory turnover means how many times a business sells and replaces its inventory in a given period of time. A low turnover rate indicates unproductive assets and lower profits. The company is holding on to too much excess inventory because it is not selling fast enough. A high turnover rate may be an indication of lost sales as products may be out of stock when a customer wants to buy them. [1]
  • The components of the formula are cost of goods sold (COGS) and average inventory.
  • The formula for calculating the inventory turnover ratio is .
  • Inventory can also be calculated by dividing sales by inventory.[
  • Determine the cost of goods sold. The cost of goods sold is the direct expense associated with providing a service or producing a product. For the service industry, cost of goods sold includes labor expenses, including wages, taxes and benefits. In retail or wholesale, the cost of goods sold is comprised of merchandise that was purchased from a manufacturer, plus the expenses associated with acquiring, storing, and displaying inventory items.[3]
    • The cost of goods sold is recorded on the income statement. It is recorded as a deduction of revenue and determines the company’s gross margin.
    • It is typically calculated with the formula 
    • For example, suppose in a 12 month period, a company has a beginning inventory of $9,000, $20,000 in purchases and an ending inventory of $3,000.
    • Calculate the COGS with the formula .
    • The COGS for that 12 month period is $26,000, and it would be recorded as an offset to revenue on the income statement.
  • Determine the average inventory. Average inventory is the median value of inventory within an accounting period.[4] The value of inventory may change significantly within an accounting period. Therefore, it makes sense to calculate the average inventory when comparing inventory to total sales or cost of goods sold. This calculation eliminates confusion from spikes in the inventory level.[5]
    • The formula for average inventory is .
    • For example, suppose in a 12 month period, a company had a beginning inventory of $9,000 and an ending inventory of $3,000.
    • Calculate the average inventory with the formula .
Apply the formula to calculate the inventory turnover ratio. Once you know the COGS and the average inventory, you can calculate the inventory turnover ratio. Using the information from the above examples, in this 12 month period, the company had a COGS of $26,000 and an average inventory of $6,000. To calculate the inventory turnover ratio, you would divide the COGS by the average inventory.
Calculating Days in Inventory

Learn the meaning of days in inventory. Once you know the inventory turnover ratio, you can use it to calculate the days in inventory. Days in inventory is the total number of days a company takes to sell its average inventory. It also determines the number of days for which the current average inventory will be sufficient. Companies use this metric to evaluate their efficiency in using their inventory.

Apply the formula to calculate days in inventory. You calculate the days in inventory by dividing the number of days in the period by the inventory turnover ratio. In the example used above, the inventory turnover ratio is 4.33. Since the accounting period was a 12 month period, the number of days in the period is 365.
  • Calculate the days in inventory with the formula .
  • It takes this company 84.2 days to sell its average inventory.
Apply an alternate formula. If you have not calculated the inventory turnover ratio, you could simply use the cost of goods sold and the average inventory figures. You would divide the average inventory by the COGS. Then you would multiply that number by the number of days in the accounting period.[7]
  • In the example used above, the average inventory is $6,000, the COGS is $26,000 and the number of days in the period is 365.
  • Calculate the days in inventory with the formula 
  • You still get the same answer. It takes this company 84.2 days to sell its average inventory.
Analyzing Days in inventory

Examine the cash conversion cycle. The cash conversion cycle measures the number of days it takes a company to convert its resources into cash flow.[8] Days in inventory is the first of three parts for this calculation. The second is the days sales outstanding, which is the number of days it takes the company to collect on accounts receivable. The third part is the days payable outstanding, which states how many days it takes the company to pay its accounts payable.[9]
  • The cash conversion cycle follows cash as it is first turned into inventory and accounts payable, then into sales and accounts receivable, and finally back into cash again.[10]
  • It measures the effectiveness of the company’s management. Having a quick cash conversion cycle shows that management has devised ways to reduce time wasted by the business by keeping items in inventory for a short time and getting payment for goods quickly. Doing both of these requires tightly managed and carefully planned systems.

Evaluate inventory effectiveness. The number of days in inventory expresses how long a company holds on to its inventory. This clarifies how long a company’s cash is tied up in its inventory. The longer a company holds on to its inventory, the more chances it has of losing money on that investment. Items in inventory can become outdated or they can expire. Also, prices can fall, which devalues the inventory.[11]
  • Holding inventory for a long period also educes return on investment, as excess capital is tied up in inventory during this time.
  • Compare your company’s days in inventory with other businesses in the same industry. The number of days in inventory makes more sense as a measure of effectiveness if you compare it with that of other businesses in the same industry. Different kinds of businesses sell their inventory at different rates. Retailers who sell perishable items have a smaller number of days in inventory than a company that sells cars or furniture. Therefore, compare your days in inventory with other businesses in the same industry to determine if you are selling your inventory efficiently.[12]
    • You can also compare your days in inventory with your own historical inventory days calculations. This will help you identify trends, positive or negative, that might be affecting your cash conversion cycle duration.
