Inventory Turnover Ratio

How fast goods move off the shelf

The Inventory Turnover Ratio tells you how many times a company sold through and replenished its entire stock during a year. It is calculated as Cost of Goods Sold ÷ Average Inventory. A turnover of 8 means the company cycled through its inventory eight times, roughly once every six weeks.

Generally, higher is better: fast-moving inventory means strong demand, efficient operations and less cash tied up in unsold goods sitting in warehouses. Slow turnover signals overstocking, weak sales, or products at risk of becoming obsolete, dead capital gathering dust.

Why it varies so much by business

The right level depends entirely on the industry. FMCG companies and grocery retailers turn inventory many times a year, their products are cheap, perishable and in constant demand. Big-ticket, slow-selling goods, jewellery, heavy machinery, real estate, luxury items, naturally turn over far fewer times, and that is normal, not a problem.

Comparing a jeweller's turnover to a biscuit-maker's is meaningless; the ratio only makes sense within a sector.

The link to working capital and quality

Inventory turnover is a key piece of the cash conversion cycle. Inventory days (365 ÷ turnover) show how long goods sit before sale; combined with receivable and payable days, they reveal how efficiently a company runs its working capital. A business that turns inventory quickly and collects fast needs less borrowed money to operate, a structural advantage.

The trend is the most useful signal. Falling turnover can warn of weakening demand, poor demand forecasting, or a pile-up of unsellable stock before it shows up in profits, a red flag for retailers, auto companies and consumer-durables makers. Rising turnover suggests sharpening operations and healthy demand.

For Indian investors, watching inventory turnover alongside revenue growth distinguishes companies genuinely selling their products from those stuffing channels or overproducing. A retailer or manufacturer improving turnover while growing sales is running a tight, demand-led operation, exactly the kind of operational discipline that compounds into durable returns.
