How to calculate EOQ?

The economic order quantity formula requires a bunch of data to work correctly:

  • Yearly demand for the product which EOQ is calculated;
  • Holding cost, which is the cost of keeping one unit of the product in the inventory;
  • Order cost, which is how much you have to pay to order the product;
  • Ordering and holding costs, as well as demand, which should remain constant during the year; and
  • That's it - you have gathered all the data for the EOQ formula!

In the next section, you may input your data into the economic order quantity formula, or follow the example provided below.

The EOQ formula

Follow the economic order quantity formula below to calculate your optimized order:

EOQ = (2 * Demand * Order costs / Holding costs)0.5

Let's go through an example to learn more about the EOQ meaning. Imagine that you have a company that sells notepads. The demand for your product throughout the year is 500,000 units. Each order costs you $10. On average, you have to pay $4 for keeping one notepad in your inventory.

EOQ = (2 * 500,000 * $10 / $4)0.5

EOQ = (2,500,000)0.5

EOQ = 1,581.14 units

Based on the provided information, we have calculated that you should order 1,581 units to keep your inventory costs their lowest. As inventory costs are optimized, you may consider changes in the product's price policy.
