What is Inventory Turnover? How to Spot Good Inventory Management
Inventory turnover reveals how fast a company sells its stock of goods.
Inventory turnover ratio divides cost of goods sold by average inventory. It measures how many times a company sells and replaces its inventory in a year. Higher turnover means inventory moves quickly. Lower turnover means stock sits in warehouses longer.
If COGS is Rs.10,000 crore and average inventory is Rs.2,000 crore, turnover is 5x. The company sells its entire inventory roughly every 73 days (365/5). A competitor with 8x turnover sells every 46 days, holding less capital in unsold goods.
Inventory Turnover = COGS / Average Inventory
If COGS Rs.15,000 Cr and Average Inventory Rs.3,000 Cr: Inventory Turnover = 15,000 / 3,000 = 5x (73 days)
What does low inventory turnover signal?
Slow-moving goods, potential obsolescence, overproduction, or weak demand. Low turnover ties up cash in inventory. In worst cases, inventory must be written down if it becomes unsaleable (common in fashion and electronics). Declining turnover over multiple quarters is an early warning.
Is very high inventory turnover always good?
Usually yes, but excessively high turnover might mean the company frequently runs out of stock, losing sales. The optimal level balances holding costs against stockout risk. Industry context matters enormously.

Frequently Asked Questions
Which industries have highest inventory turnover?
Grocery retail (DMart: 15-20x), FMCG distribution, and perishable goods. Which have lowest? Real estate (below 1x), luxury goods, and heavy equipment. Compare only within the same industry.
How does inventory turnover affect cash flow?
Faster turnover means less cash locked in inventory. If a company reduces inventory days from 90 to 60, it frees up 30 days worth of COGS as cash. This directly improves operating cash flow.
Can seasonal businesses have misleading turnover?
Yes. A company building inventory before peak season has low turnover in Q2 and high turnover in Q3. Use full-year data for meaningful comparison rather than individual quarters.
What is the difference between inventory turnover and days?
Inventory days = 365 / inventory turnover. If turnover is 5x, days are 73. Days is more intuitive: it tells you how long inventory sits before being sold. Both convey the same information differently.
Is just-in-time inventory always better?
JIT reduces holding costs but increases supply chain risk. COVID exposed JIT vulnerabilities when supply chains broke down. Companies now balance efficiency with resilience by holding strategic buffer stock.
