That’s why EOQ is rarely used alone; it must be part of a full inventory control strategy. In this example, we’re using a percentage of the item’s purchase price for what is amortization and why do we amortize simplicity. For accurate values, I recommend talking to your Finance Department, as they’ll have precise data on these cost factors. Sometimes it makes sense for a retailer to buy a product in bulk from the vendor to get a discount.
Holding cost
- This formula aims at striking a balance between the amount you sell and the amount you spend to manage your inventory.
- Calculating the cost of placing an order (Transaction Costs ) can be tricky because it’s more than a single expense.
- Beyond administrative expenses, freight and shipping costs constitute a major piece of your ordering cost puzzle, especially for physical goods.
- By ordering 110 items each time, you can reduce your overall inventory expenditures.
A next-gen inventory software can help you calculate this economic order quantity automatically, helping you make informed business decisions. Economic order quantity is a threshold value that helps businesses determine the ideal inventory that needs to be ordered while minimizing the total cost of inventory. Businesses can utilize this economic order quantity formula to optimize their inventory levels. EOQ calculation is likely to become more integrated with supply chain networks, allowing for a more holistic approach to inventory management. For instance, if the laptop business has a long production lead time of 6 months, it may need to place larger orders to ensure sufficient inventory during this period.
Example of How to Use Economic Order Quantity (EOQ)
Manufacturers also leverage EOQ calculation to optimize their inventory management processes. EOQ calculation helps manufacturers strike a balance between maintaining sufficient inventory levels and avoiding excessive holding costs. In the retail industry, EOQ calculation is crucial for optimizing inventory management, especially for fast-moving consumer goods. Retailers use EOQ to determine the optimal order quantity for products like groceries, household items, and fashion accessories.
The frequency of updates may vary depending on the industry and the business’s specific circumstances, but as a general guideline, quarterly or semi-annual reviews are recommended. EOQ calculation aims to balance ordering and holding costs, but it may not always align with a business’s service level objectives. For example, a business may prioritize customer service and rapid delivery, which could lead to higher holding costs. In such cases, the EOQ calculation may need to be adjusted to accommodate these service level requirements.

Fresh produce, dairy, meat, and bakery items can see spoilage-related shrinkage ranging from 20% to a staggering 50%. Remember that fashion retailer that got stuck with thousands of fidget spinner-themed t-shirts after the trend suddenly died? Or the grocery store that had to discard pallets of lettuce during a summer power outage? These are perfect examples of the twin inventory villains we’ll explore now. Your EOQ results directly depend on the accuracy of your cost parameters.
Calculating EOQ assists businesses in lowering inventory costs, increasing cash flow, and optimizing order sizes to meet demand efficiently. 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 assists businesses in finding the equilibrium between ordering and holding costs to avoid both overstocking and stockouts. By optimizing the order quantity, businesses can reduce the need for excessive inventory, freeing up cash that would otherwise be tied up in stock. This improved cash flow can be reinvested into other areas of the business, such as research and development or marketing efforts.
Can EOQ calculation be applied to all types of inventory?
Having precise figures isn’t just helpful—it’s the difference between optimization and missed opportunities. This formula is used to finds the expected period of time between your orders. Following these steps will give you a strong foundation whom may i claim as a dependent for optimizing inventory.
Many POS systems allow you to set reorder points, or inventory thresholds that indicate when to order more stock. When your product inventory levels reach their reorder points, you’ll be prompted to place another order. 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. But you can always make tweaks to the inputs based on your own situation.
Economic order quantity helps ensure companies manage their inventories efficiently. 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. If EOQ can help minimize the level of inventory, the cash savings can be used for some other business purpose or investment. The Economic Order Quantity is a set point sales register designed to help companies minimize the cost of ordering and holding inventory. The cost of ordering inventory falls with the increase in ordering volume due to purchasing on economies of scale. However, as the size of inventory grows, the cost of holding the inventory rises.
The EOQ model assumes constant demand and cost structures, which may not reflect real-world scenarios where demand and costs fluctuate. EOQ also assumes a fixed purchase price, but suppliers often offer quantity discounts. Sometimes, these discounts can make a larger order quantity more cost-effective than the EOQ. Economic order quantity is important because it helps companies manage their inventory efficiently. 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.
Reports from 2023 to 2024 showed capacitor lead times ranging from 10 to 26 weeks, with some electronic components extending beyond a year in certain cases. For domestic sourcing within the US, lead times vary based on your supplier, transportation mode, and product complexity. Recent data from late 2024 and early 2025 shows shippers’ tender lead times (the time between load tendering and requested pickup) averaging around 3 to 4 days. This built-in loss must factor into your holding cost calculations. The materials you purchase aren’t all destined to become finished products—some percentage will inevitably be lost during production.

While EOQ calculation is a powerful tool for inventory management, it does come with certain challenges and limitations that businesses should be aware of. Your inventory management is a living system—not a one-time calculation. Accurate lead time data, whether for domestic or international sourcing, is essential for setting appropriate reorder points. Lead time directly dictates how far in advance you must place orders to ensure that new inventory arrives before existing stock depletes. Because it directly determines when you need to place your next order.
Order quantity is not a minor issue — ordering too many items increases your holding cost, and ordering too little can result in an out-of-stock situations. Both are unfavourable for any business and should be avoided to keep your business operations viable. EOQ calculation is most effective for inventory with stable and predictable demand patterns. While it can be applied to various types of inventory, it may not be as beneficial for products with highly volatile or unpredictable demand. In such cases, alternative inventory management strategies, such as Just-In-Time (JIT) or Vendor-Managed Inventory (VMI), may be more suitable. As businesses continue to embrace digital transformation and adopt advanced technologies, the future of EOQ calculation holds exciting possibilities.
