The economic order quantity, or EOQ, is the optimal number of units a business should purchase when replenishing inventory while minimizing inventory costs that could eat into profit margins. EOQ takes into account the timing of reordering, the cost incurred to place an order, and the cost to store merchandise. If a company is constantly placing small orders to maintain a specific inventory level, the ordering costs are higher, and there is a need for additional storage space. The goal of the EOQ formula is to identify the optimal number of product units to order.
