The economic order quantity (EOQ) is the order quantity that helps minimize holding costs and order costs for your business. Use the EOQ formula to start optimizing your inventory costs.
Economic order quantity (EOQ), refers to the optimum amount of an item that should be ordered at any given point in time, such that the total annual cost of carrying and ordering that item is minimized. EOQ is also sometimes known as the optimum lot size. Simply put – how much product should you purchase to maintain a cost-efficient supply chain?
The EOQ helps companies minimize the cost of ordering and holding inventory. As explained by the economic concept known as economies of scale, the cost per unit of ordering a product falls, the larger the total quantity of the order. However, the larger the total quantity of an order, the higher the cost to hold and carry your inventory.
In short: EOQ = square root of (2 x D x S/H) or √ (2DS / H)
Example of calculating EOQ
Meet Matt. Matt runs a men’s clothing line. Matt needs to buy 12,000 shirts per year to fulfill demand (D). He incurs a setup cost of $100 (S) and a holding fee (H) of $16 per shirt. He needs to know his EOQ.
Plugging those numbers into the EOQ formula, you get:
EOQ = √ (2 x 12,000 x 100/16)
EOQ = √ $3,456,000 / $16
EOQ = √216,000
EOQ = 465 units (rounded up to the nearest whole unit)
The EOQ is usually used to set the reorder point within your inventory management workflows. Together, these metrics tell you when to place an order (reorder point) and how much order to place (EOQ formula). This prevents you from carrying too much deadstock or facing stockouts.
Minimize inventory cost.
Although the formula to calculate EOQ is simple when applied to a single product, calculating it manually for a whole inventory can be time-consuming and there is a margin for human error. Using inventory tools such as QuickBooks Commerce’s free EOQ calculator can help you save valuable time and what’s more- it's free!
