How this works
Estimate an order size balancing ordering and holding costs.
Formula
EOQ = square root of (2 × annual demand × order cost ÷ annual holding cost per unit).
Assumptions and limits
Classic EOQ assumes steady demand, instant replenishment and no quantity discounts. Rounded order size is illustrative.
Worked example
Replace the example with your own figures, then compare scenarios. Include all relevant costs and use records from matching periods.
