Inventory Turnover Formula
Managing inventory proves to be a challenging task for many managers and requires knowledge of inventory accounting basics. While the level of inventory varies from business to business, a reliable way to tell your inventory turnover rate is to utilize inventory turnover calculation measures.
The inventory turnover ratio tells you how liquid your inventory is- or how quickly your inventory can be converted into cash.
This ratio measures the number of times (on average) that your inventory is sold during a given period. It also measures how quickly your inventory can be converted into cash.
The inventory turnover ratio is calculated one of two ways. The most common way to calculate the ratio is:
The second and more accurate way to calculate the inventory turnover ratio is:
The second calculation is more accurate because "cost of goods sold" reflects your inventory's book value, and by averaging the inventory, you can reduce seasonal factors that influence the flow of inventory.
Generally, a high inventory turnover ratio means that your products are selling well. But before you get too excited about a high ratio, you need to compare it to the industry standards. If your ratio is higher than other companies in your industry, it could mean that your inventory management systems are ineffective.
