Inventory & Warehousing
EOQ, or Economic Order Quantity, is a formula used to calculate the ideal order quantity that minimizes total inventory costs, balancing the costs of ordering and holding inventory.
Full Definition
The EOQ formula helps CPG brands determine the optimal quantity of a specific ingredient or packaging material to order at one time. It seeks to find a sweet spot where the costs associated with placing orders (like administrative fees, shipping, and processing) are balanced against the costs of holding inventory (such as warehousing, spoilage, and capital tied up). By ordering the EOQ, brands can avoid ordering too frequently (which increases ordering costs) and avoid ordering too much at once (which increases holding costs and potential waste, especially for perishable CPG items).
Why It Matters for CPG Brands
For CPG brand operators, mastering EOQ is crucial for maintaining healthy cash flow and minimizing waste. Ordering the right amount at the right time prevents stockouts that disrupt production and avoids excess inventory that ties up capital and risks spoilage, which is critical for food and beverage products.
In CPG Operations
In CPG manufacturing, applying EOQ helps manage raw material inventory, like ordering a specific type of sugar or packaging film. It ensures that a snack brand doesn't run out of a key ingredient mid-production, nor does it overstock, leading to expiration or storage issues in their limited warehouse space.
Example
A small artisan jam brand producing 5000 jars of strawberry jam per month needs to order strawberry purée. Using the EOQ formula, considering their annual demand for purée, the cost to place an order, and the cost to hold the purée in their refrigerated storage, they determine the most cost-effective quantity to order from their supplier is 1000 kg every two months, rather than 500 kg monthly or 2000 kg quarterly.

Frequently Asked Questions
How does EOQ account for seasonal demand in CPG?
EOQ is based on average annual demand, so for highly seasonal CPG products, it's often used as a baseline. You might adjust your order quantities upward during peak seasons and downward during off-peak, using demand planning forecasts to fine-tune orders beyond the standard EOQ calculation.
Is EOQ still useful for perishable CPG ingredients?
Yes, but with an even stronger emphasis on holding costs. For perishable items, the holding cost component of EOQ will include a higher risk of spoilage or obsolescence, which can significantly reduce the optimal order quantity to prevent waste. It helps you find the smallest cost-effective batch.
What information do I need to calculate EOQ for my CPG brand?
You'll need three main pieces of information: your total annual demand for the item (in units), the cost to place a single order (including administrative and shipping fees), and the annual holding cost per unit (including storage, insurance, and spoilage risk).
