Stock turnover time, also known as inventory turnover time, is a measure of how quickly a company’s inventory is sold and replaced within a given period of time. It is calculated by dividing the cost of goods sold by the average inventory value during that time period. A high stock turnover time indicates that a company is efficiently managing its inventory and selling products at a fast pace, while a low stock turnover time may suggest that a company is struggling to sell its inventory and may have excess stock on hand. This metric is important for businesses to track as it can impact cash flow, profitability, and overall business operations.
