What is Inventory Turnover and Why Does it Matter?
Inventory turnover is a crucial efficiency metric that measures how many times your business sells and replaces its inventory over a specific period. It's a key indicator of operational efficiency, demand forecasting accuracy, and cash flow management.
A high inventory turnover ratio typically indicates strong sales performance and efficient inventory management, while a low ratio may suggest overstocking, poor sales, or obsolete inventory. Understanding this metric helps optimize stock levels, reduce carrying costs, and improve cash flow.
For most retail businesses, a healthy inventory turnover ratio ranges from 4-6 times per year, though this varies significantly by industry. Fast-moving consumer goods may turn over monthly, while luxury items might turn over just once or twice annually.
