What is the Inventory Turnover Ratio (ITR)?

In inventory turnover, the number of times a company sells its inventory in a year is used to measure how effectively it manages inventory. A successful business will typically have several inventory turnovers per year. In other words, the ITR is a crucial metric for businesses that sell products. The formula calculates the number of times a company has sold and replenished its inventory over a specific amount of time. This calculation can also calculate the number of days it will take to sell the inventory. 

Furthermore, the formula for calculating the ratio is derived from a mathematical calculation where the cost of goods sold (COGS) is divided by the average inventory for the same period. A higher ratio is more desirable than a low one, as a high ratio tends to point to solid sales. Knowing ITR depends on effective inventory control, also known as stock control, where the company has good insight into what it has on hand.

How to Improve Inventory Turnover Ratio?

The inventory turnover ratio is crucial for measuring how well a business sells its products. Not only it shows how often the company’s inventory is sold in a given period but also helps businesses make more intelligent decisions in various areas, including pricing, manufacturing, marketing, purchasing, and warehouse management. Ultimately, the inventory turnover ratio measures how well the company generates sales from its stock. The higher the number, the more inventory is sold, and vice versa.

One way to increase this number is by reducing average inventory levels. This is typically done by even out spikes and dips from outlier changes represented in one segment of time, like a day or month. Using centralized inventory software will help you to do so and improve your company’s inventory turnover ratio. 

3 Easy Formulas to Calculate Inventory Turnover Ratio

the formulas to calculate inventory turnover ratio

You will need to draw data from the balance sheet, so you should understand what these terms and numbers mean.

1. The cost of goods sold (COGS)

A company’s cost of goods sold, or COGS is the direct cost of producing goods for sale (including raw materials).

2. The average inventory (AI)

Over two or more specified time periods, average inventory smooths out the amount of inventory on hand.

Average inventory = beginning inventory + ending inventory/number of months

3. The inventory turnover ratio 

Over a given period, the ITR measures how often inventory is sold and replaced.

ITR = Cost of Goods Sold / Average Inventory

Inventory Turnover Ratio Example

The inventory turnover ratio is a calculation used to measure the number of times a company’s inventory is sold and replaced over a period of time. To understand how the formula works, let’s take a look at an example using XYZ Inc. According to their annual report, XYZ Inc. reported the following figures in financial statements:

  • Cost of sales of $429 billion
  • Year-end inventory of $56.5 billion, up from $44.9 billion a year earlier

To calculate ITR, we need to first find the average inventory by taking the average of the beginning and end-of-year inventories. This gives us an average inventory of:

Beginning inventory + ending inventory ($56.5 billion + $44.9 billion)

Number of months (2)

The average inventory would be $50.7 billion. Next, we can then calculate the inventory turnover ratio as:

ITR = Cost of Goods Sold / Average Inventory

= $429 billion ÷ $50.7 billion, or 8.75.

We can also use this formula to calculate the days’ inventory for XYZ Inc. . This is done by dividing the number of days in the period (in this case, 365) by the inventory turnover ratio. This gives us a days inventory for XYZ Inc. of:

= (365 ÷ 8.75), or 42 days. 

This means that, on average, XYZ Inc. turns over its inventory every 42 days during the year.

The inventory turnover ratio is the average number of how much you sell inventory items within a specified period of time. There are many benefits to maintaining a high inventory turnover ratio. The lower your ratio, the more product is likely to be on hand and ready for sale at any given moment. In this way, the ITR acts as a buffer against overstocking and allows you to respond quickly to changes in the market.
