Inventory Turnover

How many times inventory is sold and replaced over a period.

Definition

How many times inventory is sold and replaced over a period.

Why it matters

Turns link working capital to sales volume and show how efficiently inventory converts to revenue.

Formula

Cost of Goods Sold / Average Inventory Value

Example

COGS of $12M with average inventory of $3M gives 4 turns per year.

How to interpret it

Higher turns generally mean leaner inventory, but very high turns can signal stockout risk.

How to improve it

Improve forecast accuracy, reduce lot sizes, tighten safety stock policy, and clear excess stock.

Common mistakes

Comparing turns across very different product categories, or using ending instead of average inventory.
