FAQ

What is Economic Order Quantity?

EOQ is the order size that minimises the combined cost of ordering and holding inventory: √(2DS ÷ H).

How many times should I order per year?

Orders per year = annual demand ÷ EOQ. Days between orders = 365 ÷ orders per year.

What are the assumptions of EOQ?

Constant demand, fixed ordering cost and holding cost, and no stock-outs or quantity discounts.
