Inventory Turnover Ratio Formula
Inventory Turnover Ratio Formula helps you in finding a balance that is right for your business which will lead to making a profit in business.
Inventory turnover ratio is important as well as efficient ratio formula. It shows how fast can a company replaces a current period batch of inventories and transforms it into sales to find a balance that is right for your business.
Inventory turnover ratio is a ratio that shows how many times a company has replaced and sold inventory during a period, say one year, five years, or ten years.
The inventory turnover ratio is a simple ratio that helps to show how effectively inventory can be managed by comparison between average inventory and cost of goods sold for a particular period. This helps you to measure how many times the average inventory ratio is sold or turned during a particular period.
In simple words, it shows how many times a company can be sold the company’s total average inventory amount during one year. A company with $2,000 of average inventory and sales of $40,000 effectively sold its 20 times over.
The company can be able to divide the number of days in the period by the inventory turnover formula to calculate the days it takes to sell the inventory on hand. It can be calculated as sales divided by average inventory. For a oneyear period following formula can be used.
Examples of Inventory Turnover Ratio Formula
Luxurious Company sells industrial furniture for the office buildings Infrastructure During the current year; Luxurious Company reported the cost of goods sold on its income statement of $1,000,000. Luxurious’s beginning inventory was $3,000,000, and its ending inventory was $4,000,000.
Luxurious’s turnover can be calculated like the following
First, we calculate Average Inventories
 Average Inventories = Beginning Inventories + Ending Inventories) / 2
 Average Inventories = ($3,000,000 + $4,000,000)/2
 Average Inventories = $3500000
Then, we calculate Inventory Turnover Ratio using Formula
 Inventory Turnover Ratio = Cost of Goods Sold/ Average Inventory
 Inventory Turnover Ratio = $1,000,000 / $3500000
 Inventory Turnover Ratio = 0.29
As you can see, Luxurious Furniture Company turnover is .29. This means that Luxurious Furniture Company only sold roughly a third of its inventory during the current year. It also states that it would take Luxurious Furniture Company approximately 3 years to sell its entire inventory or complete one turn. In simple words, Luxurious Furniture Company does not have very good inventory control, so Luxurious Furniture Company has to Improve Inventory Control.
The same can be observed from the below formula –
 Days in Inventory = 365 / Inventory Turnover Ratio
 Days in Inventory = 365 / 0.29
 Days in Inventory = 1278 days
Another Example of Inventory Turnover Ratio Formula
Calculation of inventory turnover and days inventories outstanding for XYZ, Inc. based on the information provided as below:

 Cost of goods sold = Beginning Inventories + Cost of Goods Manufactured in a company – Ending Inventories
 Cost of goods sold = $15,000 + $250,000 – $30,000
 Cost of goods sold = $235,000
First, we calculate Average Inventories
 Average Inventories = Beginning Inventories + Ending Inventories) / 2
 Average inventories = ($15,000 + $30,000) ÷ 2
 Average inventories = $22,500
Then, we calculate Inventory Turnover Ratio using Formula
 Inventory Turnover Ratio = Cost of Goods Sold/ Average Inventory
 Inventory turnover ratio = $235,000 ÷ $22,500
 Inventory turnover ratio = 10.44
after Inventory Turnover Ratio, we calculate Days in Inventory
 Days in Inventory = 365 / Inventory Turnover Ratio
 Days inventories outstanding = 365 ÷ 10.44
 Days inventories outstanding = 34.96
Explanation of Inventory Turnover Ratio Formula
The inventory turnover ratio can be calculated by dividing the cost of goods sold for a particular period by the average inventory for the same period of time.
Cost of goods sold = Beginning Inventories + Cost of Goods Manufactured in a company – Ending Inventories
Average Inventories = Beginning Inventories + Ending Inventories) / 2
It is always a good method to use average inventory instead of taking only ending inventory because many companies’ inventory fluctuates greatly throughout the year. For instance, a company might purchase a large number of quantities of inventory on January 1 and sell that for the rest of the whole year. By December, almost the entire inventory is sold, and the ending balance does not accurately reflect the company’s actual inventory during that year. Average inventory can be calculated by adding the beginning and ending inventories of a company and dividing it by two. The cost of goods sold is reported on the profit & loss statement of a company.
Significance and Use of Inventory Turnover Ratio Formula
Inventory Turnover Ratio plays a very important role because total turnover depends on two main components of performance that is stock purchasing and sales. The first main component is stock purchasing. If a large number of amounts of inventories are purchased during the year, the company will have to sell its greater amounts of inventory to improve its turnover. If the company is failed to sell these greater amounts of inventory, it will incur storage costs and other holding costs as well.
The second component is sales. Sales must have to be matched with inventory purchases; otherwise, the inventory will not turn effectively that will make Inventory void. That’s why the sales and Purchasing departments must be in touch with each other. So, it is relevant to know the importance of Stock Purchasing and sales.
Inventory Turnover Ratio is the ratio of Cost of Goods Sold / Average Inventory during the same time period. The higher the Inventory Turnover Ratio, the more likely it is that a business is carrying too much inventory. Overstocking means that cash is being tied up in inventory assets for a prolonged period.
