The insurance, property tax and rent for each dozen tennis balls in the average inventory is $0.40. Notice that both ordering cost and holding cost are $60 at economic order quantity. The economic order quantity is the level of quantity at which the combined ordering and holding cost is at the minimum level. In my experience, many businesses struggle with order management basics. In that case, adding simple inventory principles can be a game-changer.
During peak seasons, such as holidays or back-to-school periods, demand for certain products can surge dramatically. To accommodate this, businesses must recalibrate their EOQ calculations to ensure sufficient stock levels. This often involves increasing the order quantity to prevent stockouts and capitalize on heightened consumer interest.
Also, it leads to high holding costs as the inventory tends to spend a long time in the warehouse since the supply exceeds demand for the product. One of the biggest mistakes businesses make is treating EOQ like a “set it and forget it” formula. But markets shift, customer demand evolves, and supplier prices change. That’s why it’s essential to review your EOQ inputs regularly—especially during seasonal spikes, supply chain disruptions, or changes in storage costs. Assuming all of the above, calculating inventory costs under the EOQ involves finding a balance between inventory carrying costs and order costs. Ordering a large amount at one time will increase inventory carrying costs.
Can EOQ be used for multiple products?
EOQ helps e-commerce businesses balance the need for quick shipping with the costs of warehousing and potential obsolescence in the fast-moving tech world. 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. EOQ assumes constant demand and lead times, making it less effective in volatile markets or where demand fluctuates greatly. EOQ alone doesn’t cover your back against supply and demand fluctuations.
Key takeaways
BATheories is where we talk about the various business theories and models for BA (Business Administration) students. While the Economic Order Quantity (EOQ) formula is conceptually simple, calculating and applying it consistently across a wide product range—especially in fast-paced retail environments—is anything but. By revisiting your EOQ every quarter or during major inventory reviews, you’ll ensure it continues to serve your business goals—not hold you back. We are always ready to help small businesses optimize their processes. Companies can also adapt the EOQ formula and model it according to the specifics of their business and industry.
Demand
The EOQ formula is one of several inventory calculations that small businesses can use to make their inventory management workflows more efficient. By finding the optimal balance between these two costs, companies can minimize their total inventory-related expenses. There is an inverse relationship between consignment sale definition ordering cost and holding cost. Keeping the annual demand constant if for example the number of orders decreases, the ordering cost will also decrease but the holding cost will rise and vice versa.
How to Better Manage Your Company’s Cash Flow
Here is a breakdown of its ordering cost, holding cost, and annual demand for the year. After identifying the optimal number of products, the company can minimize the costs of buying, delivering, and storing products.

Ordering costs refer to all the costs incurred each time an order is placed for inventory with the company. Using EOC helps the company stay ahead of demands and not run out of stocks.

- Economic Order Quantity is the ideal size of order that reduces the cost of holding adequate inventory and ordering costs to a minimum.
- Manufacturing companies compute it to find the optimal order size of raw materials inventory and merchandising companies compute it to find the optimal order size of ready to use merchandise inventory.
- Economic Order Quantity represents the optimal amount of inventory a company should order each cycle to keep costs as low as possible.
- The formula does not account for things like seasonality trends, bulk order discounts or the supply chain disruptions that we are facing during the pandemic.

How do you calculate EOQ?
When this balance is off, it can lead to a range of cost-related issues that impact everything from cash flow to customer satisfaction. The EOQ model also includes the term total cost (TC), which, as shown in figure below, is a non-variable value. In general, TC should be understood as the sum of fixed costs of order placement (order placement cost) and variable costs of inventory storage (inventory storage cost). Whatever the size of your organisation, having effective inventory management will help reduce costs and stockholding.
While Economic Order Quantity (EOQ) is a valuable tool for optimizing inventory, it’s not a one-size-fits-all solution. There are certain business scenarios where relying solely on EOQ may not deliver the desired results. Today, there are many ERP/MRP systems available that are designed specifically for small businesses.

By arriving at an optimal number of products to order, the company can minimize the costs for the buying, delivery, and storage of items. It reduces the likelihood of a company having excess inventory in its warehouse or store. Too much inventory means that the company is taking on unnecessary holding costs while also running the risk of increased costs due to damaged goods. On the other hand, too little inventory can lead to stock-outs which will cause you to lose sales. Having to reorder goods frequently also racks up transportation costs.By calculating EOQ, a business can determine when an order is to be placed and how much is to be ordered. This allows the company to make strides towards being as cost-efficient as possible while ensuring that production and sales continuity is guaranteed.
EOQ is part of inventory management that ensures the inventory is always monitored. It ensures that a company orders a fixed quantity every time the inventory attains a specific reorder point. Economic order quantity is important because it helps companies manage their inventory efficiently. Without inventory management techniques such as these, companies will tend to hold too much inventory during periods of low demand while also holding too little inventory during periods of high demand. When inventory falls to a certain level, the EOQ formula, if applied to business processes, triggers the need to place an order for more units. For many companies, inventory is its largest asset other than its human resources, and these businesses must carry sufficient inventory to meet the needs of customers.
- This allows the company to make strides towards being as cost-efficient as possible while ensuring that production and sales continuity is guaranteed.

- For multiple products, adjustments or different inventory management techniques may be required.
- By optimizing order quantities for various components, the manufacturer can reduce storage costs, minimize production interruptions, and maintain efficiency.
- When used effectively, economic order quantity in inventory management can help businesses reduce holding costs, improve order planning, and optimize stock levels without guesswork.

As a result, you will hardly ever experience any inventory shortages or high carrying costs. Inventory management experts use an EOQ formula to calculate the reorder quantity and ensure constant replenishment of stock. Seasonal demand fluctuations present unique challenges for inventory management, necessitating how to sue a business in small claims court adjustments to the EOQ model.

To minimize holding and order costs, the furniture company should order 26 units. The EOQ is designed to help companies or small businesses strategize to minimize their overall costs by learning the trends of their production. The Economic Order Quantity determines the inventory reorder point of a company. By doing so, the company continues to fill orders and does not run out of inventory.
