Inventory Days of Supply


Indicates how many days the current inventory will last at the current sales rate without new stock. A critical metric for ensuring stock availability.


(End Inventory / Cost of Goods Sold) * Days in Period


If the end inventory is $200,000, COGS is $1,000,000, and the period is 365 days, the days of supply is 73 days.
