EOQ Quantity Discount Formula
The economic order quantity with quantity discount formula is:
EOQ = √ (2DS) / (IC)
where,D is the Demand of the product per unit of time
S is the cost of placing the order
I represents annual inventory holding cost as percent of item total cost
C is unit cost of the item
**Note that D and H must be for the same period of time (i.e. months, years, etc).
What is Economic Order Quantity with Quantity Discount
When considering quantity discounts to determine the EOQ, it is essentially the same formula, but rather than H (holding cost) you evaluate the cost of the item (C) and multiply it by the inventory holding cost of the item as a percent of the cost on an annual basis.
