EOQ assumes you won’t see a supplier price increase in the calculated period. To find this number, check your inventory system or order records to see how many units you sold last year. This simple Economic Order Quantity (EOQ) calculator can be used for computing the economic (optimal) quantity of goods or services a firm needs to order.
This makes it hard, or nearly impossible, for businesses to account for changes in consumer demand or seasonality. If you don’t have correct, real-time data on holding or order costs, you’ll have the wrong amount what is adjusting entries of inventory, which can quickly lead to a stockout.
