About this free economic order quantity tool
Estimate an order size from annual demand, ordering cost and annual unit holding cost. Calculators answer a defined arithmetic question using the values you supply. Keep units and currencies consistent, choose the correct starting amount and inspect the assumptions before using a result. Estimates do not replace a lender quotation, an official tax rate, a medical assessment or a jurisdiction-specific deadline rule.
A practical example
