Days Inventory Outstanding (DIO)

Definition

Days Inventory Outstanding (DIO) is a financial metric that indicates the average number of days a company takes to sell its entire inventory during a specific period. This measure helps assess inventory management efficiency and is closely linked to cash flow since longer inventory holding periods can strain working capital. Companies aim for a lower DIO, as it signifies quicker sales and reduced holding costs, which are vital for effective cash and marketable securities management.
