What Is Economic Order Quantity (EOQ)?
Economic Order Quantity (EOQ) is a formula used by businesses to determine the optimal order quantity that minimizes the total inventory costs, including ordering and holding costs.
This model helps in deciding the most efficient number of units in order to reduce overall costs and streamline inventory management.
Economic Order Quantity (EOQ) Explained
The EOQ formula considers several factors, including demand rate, ordering costs, and holding costs, to calculate the ideal order size. The formula is expressed as:
Where:
- DDD is the annual demand for the product
- SSS is the ordering cost per order
- HHH is the holding cost per unit per year
Why Is Economic Order Quantity (EOQ) Important?
EOQ is crucial because it helps businesses:
- Minimize Costs: Reduces the combined costs of ordering and holding inventory.
- Optimize Inventory Levels: Prevents overstocking and stockouts.
- Improve Efficiency: Streamlines ordering processes and inventory management.
What Does Economic Order Quantity (EOQ) Tell Businesses?
EOQ provides businesses with the ideal order size to minimize costs and maximize efficiency. It tells businesses how much inventory to order and when to reorder, ensuring a balance between holding too much or too little inventory.
Benefits of Economic Order Quantity (EOQ)
- Cost Savings: Reduces overall inventory costs by balancing ordering and holding expenses.
- Improved Cash Flow: Optimizes inventory levels, freeing up capital for other uses.
- Efficient Operations: Streamlines inventory management and reduces administrative workload.
- Better Supplier Relationships: Facilitates consistent and predictable ordering patterns.
Challenges of Economic Order Quantity (EOQ)
- Accuracy of Inputs: EOQ relies on accurate estimates of demand, ordering costs, and holding costs, which can be challenging to determine.
- Dynamic Market Conditions: EOQ assumes constant demand and costs, which may not be realistic in volatile markets.
- Implementation: Requires integration with inventory management systems and processes, which can be complex and resource-intensive.
- Calculating Economic Order Quantity (EOQ) To calculate EOQ, you need to know:
- Annual Demand (D): The total quantity of a product needed over a year.
- Ordering Cost (S): The cost incurred every time an order is placed.
- Holding Cost (H): The cost to hold one unit of inventory for a year.

EOQ Examples
- Example 1: A company has an annual demand of 10,000 units, an ordering cost of $50 per order, and a holding cost of $2 per unit per year. The EOQ is:
- Example 2: A retailer needs 5,000 units of a product annually, with an ordering cost of $100 per order and a holding cost of $5 per unit per year. The EOQ is:
How to Use EOQ to Improve Inventory Management
- Implement Just-in-Time Ordering: Use EOQ to order inventory just in time to meet demand without overstocking.
- Automate Reordering: Integrate EOQ calculations into inventory management systems for automatic reordering.
- Monitor and Adjust: Regularly review and adjust EOQ calculations based on changing demand, costs, and market conditions.
- Supplier Coordination: Work closely with suppliers to ensure timely deliveries that align with EOQ recommendations.
FAQs
What is the economic order quantity?
EOQ is a formula used to determine the optimal order quantity that minimizes the total costs of ordering and holding inventory.
When is economic order quantity high and low?
EOQ is high when demand and ordering costs are high, and holding costs are low. Conversely, EOQ is low when demand and ordering costs are low, and holding costs are high.
Why is economic order quantity important?
EOQ is important because it helps businesses minimize total inventory costs, optimize inventory levels, and improve operational efficiency.
