The inventory turnover ratio is used in fundamental analysis to determine the amount of times a company sells and replaces its inventory over a fiscal period. The inventory turnover ratio compares a company's sales and its inventory. To calculate a company's inventory turnover, divide its sales by its inventory. Similarly, the ratio can be calculated by dividing the company's cost of goods sold (COGS) by its average inventory.
