Inventory Turnover

Inventory turnover tells you how many times you sold and replaced your stock in a period. This topic covers how to calculate it without fooling yourself, how to read it against your sector, and the operational levers that move it for real rather than on paper.

Turnover is a cash-efficiency metric: how hard your inventory dollars are working. A higher ratio generally means less cash tied up per dollar of sales, but pushed too far it becomes a stockout machine. The skill is raising turns while holding service level.

This topic covers the correct calculation, the traps that flatter the number, sector-aware reading, and the operational changes that move turns without quietly degrading availability.

Frequently asked questions

How do you calculate inventory turnover?

Inventory turnover equals cost of goods sold divided by average inventory at cost over the same period. Using sales (which include margin) instead of COGS, or a single point-in-time inventory instead of an average, are the two most common ways the ratio gets inflated.

What is a good inventory turnover ratio?

It is sector-dependent. Grocery and fast fashion turn many times a year; heavy equipment and luxury turn slowly by design. Compare against your own trend and close competitors, not a universal benchmark.

How do you improve inventory turnover?

Real levers are tighter demand forecasting, smaller and more frequent replenishment, faster clearance of dead stock, and trimming the long tail of slow SKUs. Simply cutting stock raises the ratio but risks stockouts; the goal is higher turns at a held service level.
