What is Inventory Turnover?

The Inventory Turnover Ratio shows how efficiently a company manages its inventory. A higher ratio generally implies strong sales or effective inventory management, while a low ratio may indicate overstocking, obsolescence, or deficiencies in the product line. To calculate it, we divide the Cost of Goods Sold (COGS) by the Average Inventory for that period.

  • Efficiency: High turnover means you aren't letting cash sit idle on shelves in the form of unsold goods.
  • Storage Costs: The faster you turn over inventory, the less you spend on warehouse rent, insurance, and handling.
  • Perishability: For businesses selling food or fashion, a high turnover is critical to avoid waste or "out-of-style" stock.
What is a "Good" Turnover Ratio? +
It varies by industry. A grocery store might have a ratio of 15-20 (very high), while a car dealership might have a ratio of 2-3. Compare your ratio with industry averages to see where you stand.
How do I calculate Average Inventory? +
This tool does it for you! It takes the (Beginning Inventory + Ending Inventory) and divides it by 2. This smooths out any seasonal spikes.
Is a very high ratio always good? +
Not necessarily. If your turnover is *too* high, you might be keeping too little stock, which can lead to frequent "Out of Stock" messages and lost customers.
