Why do the basic EOQ model variations not include the price of an item?

The basic Economic Order Quantity (EOQ) model focuses on minimizing total inventory costs, which include ordering costs and holding costs, rather than the purchase price of the item. This is because the model assumes a constant purchase price and is primarily concerned with optimizing the order quantity to balance these two types of costs. By excluding the price, the EOQ model simplifies the analysis, allowing businesses to focus on the dynamics of ordering and holding without the complexities introduced by price fluctuations. Additionally, in many cases, the price may not significantly impact the optimal order quantity when compared to the costs associated with ordering and holding inventory.
