This is a management baseline. Combine it with MOQ, case packs, variability and actual supplier lead times.
What does EOQ help decide?
EOQ provides a starting point for an efficient order quantity when demand, ordering cost and holding cost are known. Then adjust for MOQ, case packs and budget constraints.
EOQ = √(2 × annual demand × order cost ÷ annual holding cost per unit)
