It is the type of cost which is not dependent on the business more or factory overhead, which are directly used for producing those goods.

Example #1

Suppose Company C had an average inventory during the year $1,145,678, and the cost of goods sold during the same period was $10,111,987. You have required to calculate the stock turnover ratio.


Use the following data –

  • Cost of Goods Sold: 10111987.00
  • Average Inventory: 1145678.00
Example 1.1png
  • =  10,111,987 /1,145,678
Example 1.2png
  •  = 8.83 times

It means the stock rotates for 8 times.

Example #2

Stock Turnover Ratio Formula Example 2

Based on the above details, you are required to calculate the Inventory Turnover Ratio.


In this example, we are given a profit and loss statement, and we need to figure out the cost of goods sold and average inventoryAverage InventoryAverage Inventory is the mean of opening and closing inventory of a particular period. It helps the management to understand the inventory that a business needs to hold during its daily course of more as well.

Calculation of  Cost of Goods Sold

Stock Turnover Ratio Formula Example 2.1png

Cost of Goods Sold=Opening Stock + Net Purchases – Closing Stock

= 3,500,000 + ( 21,350,000 – 320,250 ) – 4,200,000

  • Cost of Goods Sold = 20,329,750

Calculation of Average Stock

Stock Turnover Ratio Formula Example 2.2png

Average Stock = ( Opening Stock + Closing Stock ) / 2

=  ( 3,500,000 + 4,200,000 ) / 2

  • Average Stock  = 3,850,000

Calculation can be done as follows,

  • =20329750.00/3850000.00

Stock Turnover Ratio will be –

Example #3

Company X is trying to evaluate 3 products that its currently selling in the market. It wants to analyze which one of the products is slow-moving and which one is the fast-moving good. On reviewing the detail of the three products, below is the summary created by the finance department.

ParticularsProduct 1Product 2Product 3
Average Revenue Earned42000000.0056000000.0049000000.00
Gross Profit Margin25.00%20.00%22.00%
Closing Stock5250000.005000000.006625000.00

Based on the above information, you are required to advise the management which goods are fast-moving and which is slow-moving?


In this example, we are given Average Revenue and closing stock. Since there is no opening stockOpening StockOpening Stock is the initial quantity of goods held by an organization during the start of any financial year or accounting period. It is equal to the previous accounting period's closing stock, valued in accordance with appropriate accounting standards based on the nature of the more information provided, we can take closing stock as a proxy for our computation purposes. Further, we are also not given purchases, and hence we cannot calculate the cost of goods sold with that formula. Still, instead, we are given a Gross profit marginGross Profit MarginGross Profit Margin is the ratio that calculates the profitability of the company after deducting the direct cost of goods sold from the revenue and is expressed as a percentage of sales. It doesn’t include any other expenses into account except the cost of goods more, so if we deduct the gross profit margin from revenue, we will get the cost of sales, which we shall we use in the below formula.

Stock Turnover Ratio formula = Cost of goods sold or cost of sales /Average Inventory or Closing stock

Cost of Sales Margin For Product 1

Stock Turnover Ratio Formula Example 3.1png


  • Cost of Sales Margin = 75.00%

Similarly, we can calculate the cost of sales margin for product 2 and 3

Example 3.5png

Cost of Sales

Stock Turnover Ratio Formula Example 3.2png
  • =42000000.00*75.00%
  • Cost of Sales = 31500000.00

Likewise, we can calculate the cost of sales for product 2 and 3

Stock Turnover Ratio Formula Example 3.6png

Calculation can be done as follows,

Example 3.3png


Example 3.4png
  •  = 6.00

Similarly, we can calculate the stock turnover ratio for product 2 and 3

Example 3.7png

Using this ratio, it appears that product 2 is fast-moving as it has the highest turnover ratio and product 3 is comparatively slow-moving goods, which is 5.77 verses 6 for product 1. Further, the gross profit margin of product 1 is better than product 3; henceforth, it is a wise decision to chose to shut down product 3 if at all, the company is taking such a decision.

How to Interpret Stock Turnover Ratio?

  • The higher the stock turnover ratio, the better it is, and it means the company sells that product very quickly, and demand also exists for that product. It might also mean that the company is frequently purchasing. It can also put the business in difficulty if prices from the suppliers’ end rise. A higher ratio may also mean that the company is missing sales opportunities as it’s not carrying adequate stock.
  • When the stock turnover is low, it would mean outdated inventory or slow-moving goods. It can be a signal toward inefficient working capital management. Nevertheless, it can be a strategy of stock building done knowingly.


Stock turnover ratio is a critical measure for a company and is widely used in financial analysis; however, it has certain limitations;

  1. Stock turnover can not be relied upon completely to draw comparisons among peers without regard to certain similarities. A manufacturing business can find its inventory turning over at a slower pace than a restaurant business.
  2. A high turnover, which is, on the one hand, good for analysts, can have a discerning side when the firm sees more cash tied-up in the system than a low turnover operation.
