Inventory turnover rate (also called stock turn rate for resellers) is the number of times an inventory turns over or is sold during a specified time period (often one year). This rate tells how quickly a business is moving inventory through the organization. Higher rates indicate that lower investments in inventory are made, thus freeing up funds for other investments. It may e computed on a cost, selling price, or unit basis. The formula based on cost is:
Inventory turnover rate = Cost of goods sold ÷ Average inventory at cost
