How do you calculate ideal stock holding?

To calculate ideal stock holding, you can use the Economic Order Quantity (EOQ) model, which determines the optimal order quantity that minimizes total inventory costs, including ordering and holding costs. Additionally, consider factors such as lead time, demand forecast, and safety stock to accommodate variability in sales and supply. The formula for EOQ is: (EOQ = \sqrt{\frac{2DS}{H}}), where (D) is annual demand, (S) is the ordering cost per order, and (H) is the holding cost per unit per year. This approach helps ensure you maintain sufficient stock levels without over-investing in inventory.
