economic order quantity
The optimal order quantity minimizing total inventory costs — balancing ordering costs against holding costs to determine the most efficient reorder amount.
Example
“The EOQ formula determined the optimal order size was 500 units — minimizing combined ordering and storage costs.”
Memory Tip
EOQ = the sweet spot order size that minimizes total inventory costs. Not too much, not too little.
Why It Matters
Understanding economic order quantity helps businesses and individuals reduce unnecessary spending on inventory management. By finding the sweet spot between ordering too frequently and holding excess stock, you can save significant money that would otherwise be wasted on storage, handling, or obsolete inventory.
Common Misconception
Many people assume that ordering in larger quantities always saves money because of bulk discounts, but this ignores the real cost of storing excess inventory. In reality, larger orders can actually increase total costs when storage, insurance, and potential waste are factored in.
In Practice
A coffee shop sells 100 cups of beans monthly and pays 50 dollars per order plus 2 dollars yearly to store each unit. Using the EOQ formula, the shop might find that ordering 20 units at a time five times per year minimizes total costs better than ordering 50 units twice yearly, even though the larger orders seem more efficient.
Etymology
ECONOMIC (cost-optimal) ORDER (purchase order) QUANTITY (amount). The most ECONOMICAL QUANTITY to ORDER.
