Hello,
I have a blog with information on reorder dates. I have a few posts that discuss EOQ.
This is my post from Feb 28th, 2008(http://excelevolution.wordpress.com/2008/02/28/eoq-economic-order-quantity/) I hope this information will be somewhat useful to you. The EOQ (Economic Order Quantity) is the most cost effective amount to order each time stock needs to be replenished. EOQ is, for all intents and purposes, an accounting formula that determines the point at which the combination of order costs and inventory carrying costs are the least. In purchase-to-stock scenarios, this is known as the order quantity and in make-to-stock manufacturing situations, known as the production lot size. While the EOQ may not be relevant in every inventory situation, most companies will find it beneficial in at least some aspect of their operation. The optimal EOQ result in this table does not affect the EOQ section in the main part of the algorithm and may benefit from some adjustment. The rationale for this is that the optimal EOQ is just the mathematical figure. Please read the EOQ notes at the base of the algorithm to get an idea of how the optimal EOQ can be further refined by taking into account other factors. Once established, this 'corrected' figure can be put into the 'Number of pallets (units) per container (EOQ)' section. The EOQ notes are as follows: *The optimal EOQ will be further refined by taking into account the following factors: If the number of units is too large, these issues may arise: Additional storage space requirements, financial outlay may be too high, risk of spoilage, risk of obsolescence, lost opportunities with invested capital, higher insurance costs & more inventory available to be stolen & damaged. If the number of units is too small, these issues may arise: Inability to benefit greatly from current pricing, quantity discounts may not be offered, more risk of damage whilst in transit if not full multiples, shipping & receiving costs per unit may be higher.

What else can I help you with?
How can EOQ be used to control inventory?
Economic Order Quantity (EOQ) is a formula used to determine the optimal order size that minimizes total inventory costs, including ordering and holding costs. By calculating EOQ, businesses can maintain an efficient inventory level, ensuring they order the right amount of stock at the right time, which reduces excess inventory and stockouts. Implementing EOQ helps streamline inventory management, leading to improved cash flow and reduced operational costs. Ultimately, it aids in balancing supply and demand effectively.
What lot-sizing technique is preferred when inventory holding costs are high?
When inventory holding costs are high, the preferred lot-sizing technique is the Economic Order Quantity (EOQ) model. EOQ minimizes total inventory costs by determining the optimal order quantity that reduces both ordering and holding costs. This approach helps to maintain lower inventory levels while ensuring that stock is replenished efficiently, thereby minimizing the burden of high holding costs. Additionally, techniques like Just-In-Time (JIT) may also be considered to further reduce excess inventory.
What are two types of inventory control methods?
Two common types of inventory control methods are the Just-In-Time (JIT) method and the Economic Order Quantity (EOQ) model. JIT focuses on minimizing inventory levels by receiving goods only as they are needed in the production process, reducing holding costs. In contrast, the EOQ model calculates the optimal order quantity that minimizes total inventory costs, including ordering and holding expenses. Both methods aim to enhance efficiency and reduce costs in inventory management.
How do you find total holding cost using EOQ method?
To find the total holding cost using the Economic Order Quantity (EOQ) method, first, calculate the EOQ using the formula ( EOQ = \sqrt{\frac{2DS}{H}} ), where ( D ) is the annual demand, ( S ) is the ordering cost per order, and ( H ) is the holding cost per unit per year. Once you have the EOQ, determine the average inventory level, which is ( \frac{EOQ}{2} ). Multiply this average inventory by the holding cost per unit to get the total holding cost: ( \text{Total Holding Cost} = \frac{EOQ}{2} \times H ).
How to reduce ordering cost?
To reduce ordering costs, organizations can consolidate orders to minimize shipping fees and take advantage of bulk discounts. Implementing an inventory management system can enhance demand forecasting, reducing excess stock and associated holding costs. Additionally, negotiating better terms with suppliers and exploring alternative sourcing options can help lower prices. Streamlining the ordering process through automation can also improve efficiency and reduce administrative costs.

What is Economic Order Quantity (EOQ) and how is EOQ calculation helpful for businesses?
Economic Order Quantity (EOQ) is a formula used by businesses to determine the optimal order quantity that minimizes total inventory costs, which include ordering costs and holding costs. By calculating EOQ, businesses can ensure they don’t overstock or understock their inventory, leading to cost savings. The EOQ calculation helps determine the ideal order quantity, taking into account factors such as demand, ordering cost, and holding cost. To calculate EOQ, the formula is: EOQ = √(2DS/H) Where: D = Demand rate (units per year) S = Ordering cost per order H = Holding cost per unit per year By using this formula, businesses can efficiently manage their inventory, reduce unnecessary expenses, and maintain optimal stock levels, improving overall supply chain management. Cloud-based ERP systems can automate EOQ calculations to streamline operations.

When inventory holding costs are high, the preferred lot-sizing technique is the Economic Order Quantity (EOQ) model. EOQ minimizes total inventory costs by determining the optimal order quantity that reduces both ordering and holding costs. This approach helps to maintain lower inventory levels while ensuring that stock is replenished efficiently, thereby minimizing the burden of high holding costs. Additionally, techniques like Just-In-Time (JIT) may also be considered to further reduce excess inventory.
What are the primary variables being balanced in the EOQ inventory model?
The primary variables being balanced in the EOQ model are carrying costs and ordering costs. The more frequent orders are placed the lower the firm's carrying costs and the higher its ordering costs.
How do you calculate ideal stock holding?
To calculate ideal stock holding, you can use the Economic Order Quantity (EOQ) model, which determines the optimal order quantity that minimizes total inventory costs, including ordering and holding costs. Additionally, consider factors such as lead time, demand forecast, and safety stock to accommodate variability in sales and supply. The formula for EOQ is: (EOQ = \sqrt{\frac{2DS}{H}}), where (D) is annual demand, (S) is the ordering cost per order, and (H) is the holding cost per unit per year. This approach helps ensure you maintain sufficient stock levels without over-investing in inventory.
Can eoq answer be in points?
Yes, the Economic Order Quantity (EOQ) can be presented in points for clarity. Key points to consider include: EOQ minimizes total inventory costs by balancing ordering and holding costs. It determines the optimal order quantity that minimizes waste and maximizes efficiency. The formula for EOQ is ( \sqrt{\frac{2DS}{H}} ), where ( D ) is demand, ( S ) is ordering cost, and ( H ) is holding cost. This concise format helps in quick understanding and application of the EOQ concept.
How lead time is related to EOQ?
Lead time is the time it takes for an order to be delivered once it is placed, while Economic Order Quantity (EOQ) is the optimal order quantity that minimizes total inventory costs. Lead time influences the reorder point in EOQ calculations – a longer lead time may require a higher reorder point to avoid stockouts. It is important to consider lead time variability and safety stock when calculating EOQ to ensure continuous supply chain operations.
What caused many firms to abandon the EOQ model for JIT?
Hello, I have a blog with information on reorder dates. I have a few posts that discuss EOQ. EOQ actually works hand in hand with JIT.

Criticism to Economic order quantity?
The assumptions included in the EOQ models are simplistic;The real cost of stock in operations are not as assumed in EOQ models;The models are really descriptive and should not be used as prescriptive devices.
How do you use EOQ to determine when to order items how many and how to order a specific number?
The Economic Order Quantity (EOQ) model helps determine the optimal order quantity that minimizes total inventory costs, including holding and ordering costs. To use EOQ, you first calculate the EOQ using the formula: (EOQ = \sqrt{\frac{2DS}{H}}), where (D) is the annual demand, (S) is the ordering cost per order, and (H) is the holding cost per unit per year. Once you have the EOQ, you can establish reorder points based on lead time and usage rates to determine when to place orders. To order a specific number, simply place an order for the EOQ amount whenever the inventory reaches the reorder point.
Compare ABC analysis with eoq method?
ABC analysis classifies items based on their importance, while EOQ (Economic Order Quantity) method calculates the optimal order quantity to minimize total inventory costs. ABC analysis helps prioritize items for inventory management, whereas EOQ helps determine the quantity of each item to order to balance holding and ordering costs efficiently.
