Inventory Turnover Calculator FAQ

What is inventory turnover?
Inventory turnover shows how many times inventory is sold and replaced during the period. It is an efficiency ratio used to evaluate stock management.

What is the inventory turnover formula?
Inventory turnover = Cost of goods sold / Average inventory. This calculator can also solve for cost of goods sold or average inventory.

What does a high inventory turnover mean?
A high inventory turnover may indicate strong sales or lean inventory management, but it can also signal understocking. The right level depends on the business model and product type.

Why use average inventory instead of ending inventory?
Average inventory usually gives a more stable picture because inventory balances can move significantly during the year. Using only ending inventory can distort the ratio.

How should I interpret inventory turnover?
Higher turnover often suggests faster stock movement and less capital tied up in inventory, but too high a ratio can mean stockouts or under-ordering. The best interpretation depends on margins, product mix, and supply chain strategy.
