Average Inventory - This value is the average amount of inventory in storage. It assumes that usage is a constant rate and that new inventory comes when the old inventory is totally used.
EOQ - EOQ (Economic Order Quantity) is the ideal number of units to buy at one purchase. This minimizes the sum of the costs to purchase the goods. It also depends on the annual usage.
Holding Cost - Holding Cost is the cost to hold one unit for one year in inventory.
