EOQ — Economic Order Quantity

Find the optimal order quantity that minimises total ordering and holding costs.

EOQ Inputs

Enter your demand, ordering cost, and holding cost to find the optimal batch size.

Demand & Cost Parameters

Annual Demand — D (units/year)

Ordering Cost per Order — S (BDT per order)

Holding Cost per Unit per Year — H (BDT/unit/year)

Unit Purchase Price (BDT — for total cost reference)

Reorder Point Inputs (Optional)

Lead Time (days from order to delivery)

Safety Stock (extra buffer units you keep)

EOQ Formula: EOQ = √( 2 × D × S / H ) D = Annual Demand
S = Ordering Cost / Order
H = Holding Cost / Unit / Year

Reorder Point: ROP = (D/365 × Lead Time) + Safety Stock
