How to Calculate Stock Turnover

Updated March 23, 2017

Stock turnover ratio is also known as inventory turnover ratio. Stock turnover ratio measures how many times inventory is sold and then replaced in a given period. The period depends on the user, but is normally either monthly, quarterly or yearly. Stock turnover ratio is important because it will give management and investors an idea of how quickly a firm moves its inventory.

Determine a company's sales. Company's disclose their sales numbers on the income statement of their financial statements. An analyst can also use cost of goods sold, which is also on the company's income statement.

Divide either sales by inventory or cost of goods sold by average inventory to determine stock turnover ratio.
