Holding cost (also known as carrying costs) refers to the total cost of holding inventory. How much do you spend on holding and storing inventory, per unit, per year? In order to properly calculate EOQ, you’ll first need to determine your holding cost. You probably noticed that some of the variables require information on an annual timeline. That’s because the EOQ formula makes certain assumptions that demand, setup costs, holding costs and goods prices are always constant. Holding cost is the total costs a company incurs to hold inventory in a warehouse or store.

  1. Holding costs would also be defined as opportunity costs of investing money elsewhere rather than putting it in buying inventory.
  2. This means that the optimal number of inventory units for your brand to purchase in a given restocking order is 3,652 units.
  3. Conversely, if the business firm buys smaller quantities in too many orders during a year, the ordering cost goes up.
  4. Using EOQ to balance your inventory can be challenging, but logistics partners like ShipBob can take some of the heavy lifting off your plate.
  5. The economic order quantity, or EOQ, is the optimal number of units a business should purchase when replenishing inventory while minimizing inventory costs that could eat into profit margins.

EOQ is based on ordering products from a third party, while EPQ refers to products being manufactured by the business, and therefore takes rate of production into account. Inventory managers use EPQ to determine optimum lot sizes during production in order to minimise equipment setup and product storage costs. Generally speaking, EOQ assumes that all things remain constant all year. It doesn’t take account of the fact that there are variables that can fluctuate at different times of year, such as demand, costs, lead times, discounts and part shipments.

You can check inventory counts in real-time, set automatic reorder points, and better forecast demand. No formula can account for all the unforeseeable surprises that affect your inventory balance. Unexpected supply chain blockages, theft, spoilage, and more can mess with your inventory levels, and cause your EOQ merchant service website1 calculations to be less effective. The EOQ formula can be paired with the reorder point formula, which helps a business identify when it should order more inventory. Using these calculations together can help a business avoid running out of stock for its products without carrying more inventory than it needs to.

The second assumption is about the invariability of ordering and holding costs. The model supposes that the costs such as transportation expenses and warehouse rent either do not change or do not affect the ordering and handling costs, which is not entirely realistic. It has become a cash flow tool that can minimize the amount of cash and the inventory cost integrated into the inventory balance.
