Inventory Turnover
Inventory turnover counts how many times a company sells through its entire stock in a year: cost of goods sold divided by average inventory. A turnover of 6 means the shelves clear out six times annually, roughly every 61 days.
Fast turnover is capital efficiency — less money parked in warehouses per dollar of sales, less exposure to fashion cycles, spoilage, and obsolescence. But the metric rewards different things in different models: a discount grocer at 15x and a luxury jeweler at 1.5x can both be excellent businesses, because the jeweler's fat gross margin pays for the slow shelf.
Falling turnover with rising gross margin can flag trouble ahead: the company is holding price while product piles up, and the correction usually arrives as one big markdown quarter.
COGS for the year is $600M. Inventory started at $90M and ended at $110M, so average inventory = (90 + 110) / 2 = $100M. Turnover = 600 / 100 = 6.0x, which works out to 365 / 6 = 60.8 days of inventory on hand.
