How Inventory Turnover Ratio Works

We have established that the inventory turnover ratio is the amount of time a business takes to sell and replenish goods. It works by simply providing insight into how well your business is doing in terms of inventory management, which is critical to the success of any retail company.

A high ratio usually indicates high sales and may also mean that your stock levels are low and you cannot meet demands. A low ratio suggests poor sales and may also imply that you have too much inventory, are stocking goods nobody wants, or not putting in enough effort in marketing.

How Do You Calculate Inventory Turnover Ratio (ITR)?

The inventory turnover ratio is calculated by dividing the cost of goods sold by the average inventory available. The cost of goods here is how much is expended to produce or purchase a product sold within a particular time, for example, a month.

The cost of goods sold is calculated by summing up the cost of goods you had at the beginning of the month with any other inventory costs you made within that same month. After this, you subtract your inventory at the end of the month from the total sum to determine your cost of goods sold.

The average inventory, in this case, is the value of all the goods you have in stock. However, since the value can vary over a year, it is essential to use an average sum, not the exact value at the end of that year or whatever period.

It is important to note that the average inventory does not have to be calculated every year. It could be quarterly or monthly, for whatever period is needed for analysis.

For example, if your goods or inventory value were $1000 at the beginning of a year and $3000 at the end, your average inventory value would be $2000. If the cost of goods sold were $3000, your inventory turnover ratio would be 1.5.

A higher inventory ratio means you were able to make more sales and you understood the varying demands of consumers. On the other hand, a low ratio shows poor sales and a decline in the need for your products.

The inventory turnover ratio can show how well your sales and buyers are in sync. If their relationship is seamless, it would improve sales and increase turnover.
