Inventory Turnover Ratio:
This ratio is a relationship between the cost of goods sold during a particular period of time and the cost of average inventory during a particular period. It is expressed in number of times. Stock turnover ratio/Inventory turnover ratio indicates the number of time the stock has been turned over during the period and evaluates the efficiency with which a firm is able to manage its inventory.
The formula for calculating inventory turnover ratio is as follows:
Inventory Turnover Ratio = Cost of Goods SoldAverage Inventory at Cost
Cost of Goods Sold = Opening Stock + Purchase + Direct Expenses – Closing Stock
Alternatively, Cost of Goods Sold = Net Sales – Gross Profit
Average Inventory = Opening stock + Closing Stock2
From the above formula, it is clear that this ratio reveals the average length of time for which the inventory is held by the firm.
