By optimizing order quantities for various components, the manufacturer can reduce storage costs, minimize production interruptions, and maintain efficiency. By finding the optimal balance between these two costs, companies can minimize their total inventory-related expenses. Additionally, the economic order interval8 can be determined from the EOQ and the economic production quantity model (which determines the optimal production quantity) can be determined in a similar fashion. Mismanaged inventory is a supply chain nightmare for any retailer. It can lead to understocked stores, lost revenue, and — worst of all — unhappy customers who never return.
Understanding your business’s EOQs is crucial for creating a positive customer experience and saving your company money on inventory costs. It can be difficult to forecast the exact optimal number of stock to have on hand at your business and may result in cautious calculations that cause you to order smaller amounts. This under-ordering may cause inventory shortages, which can lose your business money. Economic order quantity is important because it helps companies manage their inventory efficiently.
The limitations of the EOQ model are based on the assumptions made in the formula derivation. The EOQ assumes consumer demand, ordering costs, and holding costs to be constant. The economic order quantity model is an important consideration because it helps to find the optimal number of units per order. The firms can minimize their material acquisition costs by applying the EOQ model. Since the inventory demand is assumed to be constant in EOQ, the annual holding cost is calculated using the formula.
What Is Economic Order Quantity and How Can I Calculate It?
Retailers miss out on $1 trillion every year due to stockouts alone. Selling out of a popular product could result in lost sales and lost shoppers, because they’ll go to another store to find the desired product. Determining EOQ is one of the most efficient ways to guarantee you’ll have enough stock available. By determining a reorder point, the business avoids running out of inventory and can continue to fill customer orders. If the company runs out of inventory, there is a shortage cost, which is the revenue lost because the company has insufficient inventory to fill an order. An inventory shortage may also mean the company loses the customer or the client will order less in the future.
By applying EOQ principles, the restaurant can reduce food waste, ensure ingredient freshness, and keep costs under control. This illustrates that the economic order quantity is always in the best interests of the firm. If you have more inventory than you need, you are wasting money, space, and personnel dedicated to caring for that inventory.

- The EOQ systematises warehouse stock procurement, defining when to place orders with suppliers and in what quantities.
- Having too much inventory results in higher costs that take away from profits due to the cost of maintaining inventory and sometimes having to discard old inventory.
- This number is different for every item, as each item will have a unique EOQ.
- Too much of one product can increase storage costs and reduce available cash flow.
- You can’t simply measure EOQ at the beginning of the year and expect it to hold true.
- There is an inverse relationship between ordering cost and holding cost.
The most important costs incurred in any manufacturing operation are material, labor, and factory overhead. Assume, for example, a retail clothing shop carries a line of men’s jeans and the shop sells 1,000 pairs of jeans each year. It costs the company $5 payroll fraud per year to hold a pair of jeans in inventory, and the fixed cost to place an order is $2. Ordering is the cost of placing an order to the supplier for inventory. The annual quantity calculates the number of orders demanded divided by the volume per order. Malakooti (2013)10 has introduced the multi-criteria EOQ models where the criteria could be minimizing the total cost, Order quantity (inventory), and Shortages.
Example of How to Use Economic Order Quantity (EOQ)
The concept of economic order quantity equation helps in cash flow management by bringing a balance in the quantity of orders and funds required for the same. It is necessary to strike this balance because inventory is extremely essential because it is the main asset that helps to run the business.

- Economic order quantity helps ensure companies manage their inventories efficiently.
- By determining a reorder point, the business avoids running out of inventory and is able to fill all customer orders.
By adding the holding cost and ordering cost gives the annual total cost of the inventory. For calculation of the EOQ, that is, optimal quantity, the first derivative of the total cost with respect to Q is taken. Assume that a company has steady demand of 12,000 units per year for one of its products.
By using your EOQ calculations, you’ll be better able to take advantage of these perks. 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. Conversely, if the business firm buys smaller quantities in too many orders during a year, the ordering cost goes up. The John Sports Inc. purchases tennis balls at $20 per dozen from its suppliers. The John Sports will sell 34,300 dozen of tennis balls evenly throughout the year.
By applying EOQ, you can keep your store stocked with the right amount of inventory, reducing the risk of stockouts during peak times or being stuck with excess inventory when demand drops. By keeping the above values in the below tabular equation, we get the total cost with different volumes. An annual ordering cost is the number of orders multiplied by ordering costs.
Based on the variables mentioned above, EOQ is represented by the annual demand for the product in question (D), the cost of placing an order (K) and the cost of holding one unit in inventory throughout the year (G). Retailers and e-commerce companies have to be particularly careful with their inventory. While overstock can drive up costs, stockouts could result in missed sales opportunities.

When you use economic order quantity (EOQ), you eliminate the need for guesswork as you order stock, and ensure you don’t over-order or run out too quickly. The EOQ formula is data-driven, and when combined with expense and inventory management software, makes it simple to stay on top of your company’s inventory needs.
Importance of calculating EOQ
This is important, as holding inventory on-site results in additional real estate costs, security fees, utility bills, insurance premiums, and other related costs. Economic order quantity will be higher if the company’s setup costs or product demand increases. On the other hand, it will be lower if the company’s holding costs increase. EOQ might not be a 100% accurate tool to calculate the optimal order quantity, but it helps the business improve its inventory management. Despite its limitations, EOQ is a powerful production-scheduling technique to make inventory-related decision-making more smooth.

For many companies, inventory is the largest asset owned by the company, and these businesses must carry sufficient inventory to meet the needs of customers. If EOQ can help minimize the level of inventory, the cash savings can be used for some other business purpose or investment. It helps to find a production volume or order that the company should add to minimize the holding cost and order cost.
And if you lack space to store your EOQ, we’ll explore how to optimize it with storage systems. The carrying costs and ordering costs are the two most important considerations in EOQ. When a company is using EOQ, its overall efficiency of handling the inventory is increased. You can smartly calculate the EOQ by taking into consideration of all important cost variables. The economic order quantity is the optimum quantity of an item to be purchased at one time in order to minimize the combined annual costs of ordering and carrying the item in inventory. This concept arises from the fact that the cost remains under control but the required demand is met.
