Days in inventory(DII) is an efficiency ratio that measures the average number of days the company holds its inventory before selling it.

The formula for DII is:

DII=averageinventoryCOGS/Days

where the average inventory is the average of inventory levels at the beginning and end of an accounting period, and COGS/day is calculated by dividing the total cost of goods sold per year by 365 days.[1]
