Download the Wilson Formula Excel here, Test it first with a few products, the most important for your business.

If you wait for 90%, in most cases, you’re probably slow. Most decisions should probably be made somewhere around 70% of the information you wish you had. I like this quote from Jeff Bezos, Amazon’s CEO: In those cases, implementing simple inventory management principles step-by-step can often bring great results. I have seen so many businesses where order management was lacking the most basic rules or processes. By trying to implement it in your inventory management, you will be more aware of your own supply chain challenges. The EOQ formula is an overly simplistic solution to a very broad problem (as with any problem in Supply Chain). The objective of the economic order quantity (EOQ) model is to minimize the total costs associated with the carrying and ordering costs as the mount ordered gets larger, average inventory increases and so do carrying costs. The last two problems can be partially solved using a reorder point policy with safety stocks.

No Safety Stock: using EOQ doesn’t cover any risk.

We will also assume a constant, continuous, production rate.

We will assume that demand is constant and continuous over an innite horizon. time each EOQ arrives, and the average number on backorder during the order cycle is 3.18. The EPQ balances the average xed ordering cost (that decreases with large orders) and the average inventory holding cost (that increases with large orders). Demand & Lead time not steady: need to vary the frequency and group orders. and safety stocks to meet a variety of customer service goals.Then, the quantities per order can be bigger than the EOQ. Purchase price discounts: it can be more attractive in comparison to the EOQ savings.

We saw how to use the EOQ formula in Excel through various examples, and we deducted the corresponding frequency to order. The Economic Order Quantity is a good tool to minimize total costs, as it is the theoretical optimal quantity to order in Inventory Management.
