Formula
How it works: Inventory turnover measures how many times you sell and replace inventory per year. Higher is generally better (faster cash conversion). Days on hand = 365 / turnover ratio tells you how long stock sits before selling.
Worked Example
What Is Inventory Turnover and Why Is It a Key Business Metric?
Inventory turnover is a vital financial ratio that reveals how many times a company has sold and replaced its inventory within a specific period, usually one year. Calculated by dividing the Cost of Goods Sold (COGS) by the average inventory value, this metric offers a direct insight into the efficiency of a business's stock management.\n\nA high inventory turnover generally suggests strong sales, effective purchasing, and minimal risk of obsolete or expired stock, indicating that products are moving quickly through the supply chain. Conversely, a low turnover may point to weak sales, excessive inventory levels, poor purchasing decisions, or outdated products, all of which can tie up capital and incur additional storage costs.\n\nUnderstanding this ratio is fundamental for optimizing inventory levels, preventing stockouts or surplus inventory, and ultimately enhancing cash flow and profitability. It is a critical performance indicator for any business dealing with physical goods.
- It measures how fast inventory is sold and replaced, directly affecting cash flow.
- A higher ratio typically signals efficient sales, reduced holding costs, and less capital tied up in stock.
- A lower ratio can indicate slow sales, overstocking, or potentially obsolete inventory.
- Helps businesses optimize purchasing, pricing, and marketing strategies for better operational efficiency.

Frequently Asked Questions
What is a good inventory turnover ratio?
It varies by industry. Grocery: 14-20x. Fashion: 4-6x. Electronics: 6-8x. Generally, 4-6x is healthy for most retail businesses. Higher means faster sales but risk of stockouts.
What are "days on hand"?
Days of inventory on hand = 365 / turnover ratio. It tells you how many days your current stock will last. Lower is better for cash flow but too low means stockout risk.
How do I improve inventory turnover?
Identify and liquidate slow-moving stock, improve demand forecasting, reduce order quantities and order more frequently, negotiate faster supplier lead times, and run promotions on aging inventory.
