Days in Inventory is a measurement of the number of days an item spends in inventory.
Days in Inventory = (Inventory / Cost of Sales) x 365
A company has inventory of $4,000 and cost of sales of $2,000.
Days in Inventory = ($4,000 / $2,000) x 365 = 2 x 365 = 730
Therefore, an item will spend 730 days in inventory.
