Inventory Turnover measures how fast the company turns over its inventory within a year. A higher inventory turnover means the company has light inventory.

Usually retailers pile up their inventories at holiday seasons to meet the stronger demand. Therefore, the inventory of a particular quarter of a year should not be used to calculate inventory turnover. An average inventory is a better indication.
