What is Inventory Turnover Rate

Inventory Turnover is a key performance indicator (KPI) that measures how many times a company sells and replaces its entire inventory within a specific time period, typically a fiscal year. It is a critical efficiency metric that helps businesses assess the effectiveness of their inventory management, pricing strategies, and product demand forecasting. A higher turnover rate often indicates strong sales and effective inventory control, while a lower rate may suggest overstocking, weak demand, or supply chain issues. Inventory turnover varies by industry, with fast-moving consumer goods typically having higher turnover than luxury or specialty products. Monitoring this ratio enables companies to optimize purchasing, manufacturing, and marketing decisions to better align with market demand.
