Understanding EOQ Basics in Ecommerce Inventory Management:
Part 1

Introduction to EOQ

EOQ stands for Economic Order Quantity. It's a fundamental formula used in inventory management to determine the optimal order quantity that minimizes the total cost of inventory, including holding and order costs. This concept has been around for over a century and remains a cornerstone of effective inventory management.

However, having said that, the EOQ best acts as a sounding board for third party ecommerce sellers. Sellers who are purchasing finished goods from factories, rebranding them, and then selling on their own websites and other ecommerce platforms. The EOQ helps inventory managers find the perfect mathematical balance between the cost of ordering inventory and the cost of holding it. By optimizing order sizes,as the theory goes, businesses can reduce excess inventory, minimize storage costs, and avoid stockouts. However, that based on perfect spreadsheet math, not real life for a third party ecommerce seller.

Importance of EOQ in Inventory Management

EOQ is crucial for inventory management as it helps in maintaining an optimal balance between ordering costs and holding costs. By determining the ideal order quantity, businesses can significantly reduce excess inventory, lower storage costs, and prevent stockouts. This optimization leads to more efficient operations and increased profitability.

In the fast-paced world of ecommerce, where customer expectations are high, having the right inventory at the right time is paramount. EOQ helps businesses to avoid the pitfalls of running out of products or holding too much inventory, which can lead to cost savings and improved customer satisfaction.

How to Calculate EOQ

To calculate EOQ, you need the following data:

• Annual Demand (A): The total number of units required per year.
• Order Cost (B): The cost of placing an order, including freight forwarder fees.
• Annual Holding Cost (C): The cost to hold one unit of inventory for a year.

The EOQ formula is:

Where:

• A is the annual demand
• B is the order cost
• C is the annual holding cost per unit

Example Calculation

Let's walk through an example:

• Annual Demand (A): 22,500 units
• Order Cost (B): $3,000
• Annual Holding Cost (C): $2.40 per unit

Plugging these values into the formula:

EOQ = sqrt((2 * 22,500 * 3,000) / 2.40) = sqrt(56,250,000) = 7,500 units

This means the optimal order quantity is 7,500 units.
