Understanding Inventory Turnover in E-commerce

Quick Definition

Inventory Turnover is a critical financial metric measuring how many times a company sells and replaces its inventory during a specific period. It reveals the efficiency of inventory management, indicating how quickly products are sold and restocked. A higher turnover rate suggests strong sales and effective inventory control, while a lower rate may signal overstocking or weak demand.

Understanding Inventory Turnover

Calculating Inventory Turnover

Inventory Turnover = Cost of Goods Sold ÷ Average Inventory Value

Example Calculation:

Annual Cost of Goods Sold: $500,000

Beginning Inventory: $100,000

Ending Inventory: $150,000

Average Inventory: ($100,000 + $150,000) ÷ 2 = $125,000

Inventory Turnover = $500,000 ÷ $125,000 = 4 times per year

Why Inventory Turnover Matters

•
