Inventory Management KPIs

Inventory can play a key role in the health of your business; the right management of a company’s stocks affects the business’s flourishing.

likely, using key performance indicators (KPIs) can improve stocks management, inventory tracking, and making better decisions about it.

Inventory management software allows businesses to manage their KPIs efficiently, giving you a look in-depth at your business, as well as evaluating your supply chain performance at different levels of your business.

There are multiple KPIs used to assess the supply chain performance, here are some of them:

Inventory Turnover

It is the most basic business performance indicator; it shows you the number of times inventory has been sold and replaced in a given time period.

This KPI tells you how fast a company is making sales from its inventory.

If the turnover is low, it indicates the company has either weak sales or excess inventory. On the contrary, the high rate shows that the company has strong sales.


Inventory turnover rate = Sales / inventory.

Inventory Turnover kpi


Inventory turnover rate = cost of goods sold / average inventory.

Days Sales in Inventory (DSI)

This KPI measures the time period that it takes for your inventory to turn into sales.

It is one of the most important metrics that determine the company ability to quickly sell its goods and it reflects the good management of your inventory.

if the number is high, it points to inventory management problems or inefficient sales strategy. On the other hand, the lower the number, the better as it indicates the quick selling of inventory which means, lower inventory storing cost and less time.


DSI= (Average Inventory ÷ Cost of Sales) x 365.
