  2. The reorder quantity is the inventory a business should order when the reorder level is reached.

What is the Reorder Level?

The reorder level, also known as the reorder point, is the inventory level at which a business decides to replenish its stock. It is the point at which you initiate a new purchase order to ensure a continuous supply of products. Calculating the reorder level accurately is essential for maintaining a balance between carrying costs and the risk of stockouts.

The time it takes for an order to be delivered significantly determines the reorder level. Longer lead times require higher safety stock to prevent stockouts. Businesses with fluctuating demand may set a higher reorder level to account for unexpected spikes in sales.

The desired service level, expressed as a percentage, determines how frequently a business is willing to risk stockouts. Higher service levels require higher reorder levels.

What is Reorder Quantity?

The reorder quantity, also known as the order quantity or economic order quantity (EOQ), is the amount of inventory a business should order when the reorder level is reached. Determining the right reorder quantity is essential for minimizing holding costs and ordering costs while ensuring a consistent supply of products.

The economic order quantity (EOQ) formula minimizes total inventory costs, including holding and ordering costs. By finding the optimal order quantity, businesses can reduce unnecessary expenses associated with excess inventory or frequent small orders. Maintaining the right reorder quantity ensures that the product moves through the supply chain efficiently.

  4. The reorder level focuses on mitigating the risk of stockout situations, while reorder quantity addresses the balance between holding excess inventory (costs) and ensuring sufficient stock.
  5. The reorder level is calculated using the formula: Reorder level = Lead Time Demand + Safety Stock. In contrast, reorder quantity is calculated based on factors like EOQ (Economic Order Quantity) or a predetermined amount.
