Assumption of Constant Ordering and Holding Costs

The EOQ assumes that holding and ordering cost remain constant, which may not always be the case. An increase or decrease in your transport charges, a change in the salary of your employees, or rising rent for your warehouse can all impact your costs and affect the calculations that go into the EOQ. The Economic Order Quantity (EOQ) formula helps to avoid these mis-stocking situations. It calculates the ideal number of units you should order, such that the cost involved is minimal and number of units is optimal. It is a measurement used in the field of Operations, Logistics, and Supply Management.

  • Without inventory management techniques such as these, companies will tend to hold too much inventory during periods of low demand while also holding too little inventory during periods of high demand.

Ordering costs refer to all the costs incurred each time an order is placed for inventory with the company.

In essence, EOQ is a tool used to determine the volume and frequency of orders required to satisfy a given level of demand while minimizing the cost per order. So a business would see it needs to reorder new materials soon based on its EOQ figure, but usually it’s not able to purchase less than the MOQ set by the company from which it makes that order.
