Economic Order Quantity 

  • Posted On: January 27, 2025

Efficient inventory management is crucial for every business, and the EOQ formula is one of the most powerful tools to help achieve this.  

Whether you’re a small business or a large-scale operation, understanding how to optimize your inventory orders can significantly reduce costs and streamline operations. 

At Teamship, we’ve seen how smart inventory practices can make a difference for brands and warehouses alike.  

Let’s get into the key aspects of economic order quantity EOQ and how it helps manage inventory effectively. 

What is Economic Order Quantity? 

The Economic Order Quantity (EOQ) is a fundamental inventory management concept that helps businesses determine the ideal order size.  

It ensures the perfect balance between ordering too often (which increases ordering costs) and ordering too much (which increases holding costs). 

By using the EOQ equation, businesses can minimize these costs and ensure smooth operations without overstocking or stockouts. 

The EOQ Model Formula 

The EOQ model formula is straightforward: 

EOQ = √2SD/H 

Here’s what the components mean: 

  • D: Annual demand (units required per year) 
  • S: Ordering cost (per order) 
  • H: Holding cost (per unit per year) 

Using this formula, you can calculate the optimal order quantity to save costs and improve efficiency. 

Benefits of Using the EOQ Formula 

1. Cost Reduction 

The EOQ formula minimizes the total cost of inventory by finding the balance between ordering and holding costs.  

For instance, fewer orders mean lower ordering costs, while optimal stock levels reduce storage expenses. 

2. Improved Efficiency 

With the right order quantities, businesses avoid delays caused by stockouts and prevent overloading warehouses with excess inventory. This leads to smoother operations across the supply chain. 

3. Better Cash Flow 

By maintaining optimal stock levels, businesses free up cash that would otherwise be tied up in excess inventory.  

It can be reinvested in other areas of growth. 

4. Enhanced Decision-Making 

The EOQ model provides a data-driven approach to inventory management, making it easier to forecast needs and allocate resources effectively. 

When paired with tools like a WMS, such as Teamship, applying the EOQ equation becomes even more straightforward and actionable. 

Why EOQ Matters for Your Business? 

Understanding what is economic order quantity can help businesses make smarter decisions about how much to order and when.  

This insight is especially valuable for businesses managing large inventories or working with multiple warehouses.

Frequently Asked Questions 

1. Can the EOQ formula be used for seasonal products? 

Yes, but you’ll need to adjust the variables based on seasonal demand.  

For example, during peak seasons, the demand (D) will increase, leading to higher order quantities.  

Conversely, in off-peak seasons, the formula will recommend smaller orders to avoid overstocking. Regular reviews of the EOQ variables are essential for seasonal businesses. 

2. How does EOQ work for perishable goods? 

For perishable goods, holding costs (H) are typically higher because of their limited shelf life and storage requirements, such as refrigeration.  

The EOQ formula can still be used but will often suggest smaller, more frequent orders to minimize the risk of spoilage while balancing costs. 

3. Is the EOQ model formula accurate for businesses with fluctuating demand? 

The EOQ formula works best when demand is stable, but it can still be applied to fluctuating demand if the variables are regularly updated.  

For businesses with frequent demand changes, incorporating technology like a WMS can automate EOQ calculations and adapt them in real time
