MANUFACTURING – LEAN MANUFACTURING & PRODUCTION PLANNING CALCULATOR
Inventory Turnover
A precise tool.
What is the Inventory Turnover & How does it work?
Inventory turnover measures how efficiently a company converts its inventory into sales. A higher ratio indicates that inventory is sold and replenished quickly, reducing holding costs and the risk of obsolescence. In lean manufacturing, monitoring turnover helps identify bottlenecks and excess stock, enabling continuous improvement and just‑in‑time production. By aligning production schedules with actual demand, firms can maintain low inventory levels without sacrificing service. The standard calculation divides the Cost of Goods Sold (COGS) by the average inventory over the period. This ratio provides a clear, comparable metric across periods and competitors, supporting strategic decisions on purchasing, pricing, and capacity planning.
\text{Inventory Turnover}=\frac{\text{COGS}}{\text{Average Inventory}}
COGS = Cost of Goods Sold, Average Inventory = (Beginning Inventory + Ending Inventory)/2
