Reordering Point- This formula is used to calculate the reordering point, i.e., point at which one gets a trigger to order inventory.

However, as the size of inventory grows, the cost of holding the inventory rises. Therefore, this method is only advisable for certain organizations in which demand and cost remain relatively stable over the course of the year. If, for example, the cost of the raw material varies according to seasonality, the EOQ formula would be ineffective, as it doesn’t consider that variable.

The economic order quantity, also called optimal order quantity, is the optimal number of products a business should include per order to reduce order costs, shortage costs, and storage costs. The EOQ is a company’s optimal order quantity that minimizes its total costs related to ordering, receiving, and holding inventory. These costs play a big part in determining the economic order quantity of an item, since they contribute to total inventory costs and influence several important components of order fulfillment.

Number of orders – Number of orders is determined by dividing annual quantity demanded with a volume per order. The EOQ is usually used to set the reorder point within your inventory management workflows.

## What is safety stock level?
