Inventory management KPIs

Inventory management ensures optimal stock levels and efficient resource utilization. It encompasses a range of KPIs, each measuring a different aspect of inventory control, from accuracy and turnover to carrying costs and shrinkage. 

1. Inventory accuracy

Inventory Accuracy is defined as the degree to which the inventory data—quantity and location—matches the actual physical inventory in the warehouse. It is typically expressed as a percentage, where a higher percentage denotes a closer match between the records and the physical count.

(Number of Accurate Inventory Records / Total Inventory Records) X 100 = Inventory Accuracy Percentage.

This KPI measures how well a warehouse tracks and maintains its stock and is also a crucial indicator of the health and efficiency of the entire supply chain.

To effectively monitor and optimize inventory accuracy, establish a baseline, set target accuracy levels, and track performance over time. This involves regular analysis of discrepancies and identifying root causes for inaccuracies.

2. Inventory turnover rate

The Inventory Turnover Rate measures how often a company's inventory is sold and replaced over a specific period, typically a year. This KPI is central to evaluating the efficiency of inventory management practices and sales health.

Total Cost of Goods Sold / Average Inventory = Inventory Turnover Rate

Use this KPI to gain insights into the balance between inventory levels and sales performance, indicating whether inventory is being used effectively or if improvements are needed.

To effectively monitor and optimize the Inventory Turnover Rate, businesses should regularly compare it against industry benchmarks, assess trends over time, and adjust inventory strategies accordingly. This includes reviewing purchasing patterns, sales strategies, and inventory management practices.

3. Carrying cost of inventory

The carrying cost of inventory refers to the total costs of holding and storing unsold goods. These costs typically include storage fees, insurance, employee wages, depreciation, and opportunity costs.
