What is Economic Order Quantity (EOQ)?

Economic Order Quantity (EOQ) is a formula used to determine the optimal order quantity that minimizes the total inventory costs, including ordering costs and holding costs.

It helps organizations find the right balance between ordering too much (resulting in higher holding costs) and ordering too little (resulting in higher ordering costs).

What is Period Order Quantity?

Period Order Quantity is the quantity of items that should be ordered during a specific time period to maintain an optimal inventory level.

You can calculate the number of weeks the ordered quantity is intended to meet the requirements by dividing the Economic Order Quantity by the average weekly usage.
