By using the reorder point formula, you know that when your inventory reaches 175 red bandanas, you need to replenish your inventory so you don’t experience shortages. Even if there are production shortages or shipping delays, Archon Optical’s safety stock ensures they can sell Ghost glasses for two more weeks before running out of stock. For a quick rundown of reorder points and safety stock and their importance in inventory management, check out this short clip from our new podcast. Calculating reorder points may not seem like fun, but they can help you get the most value out of your inventory.
So let’s talk about how to figure out these essential stock management metrics. The main difference is that you must calculate your reorder point for a product each day. This will update your data and let you determine the most optimal time for reordering. It also allows you to notice sudden shifts in demand and react accordingly to avoid causing the bullwhip effect in your supply chain.
If you want to learn about other key performance indicators and strategies, like inventory turnover ratio or the retail inventory method, check out our inventory management guide. From the above formula it can be easily deduced that an order for replenishment of materials be made when the level of inventory is just adequate to meet the needs of production during lead-time. To mitigate these risks, it’s essential to have contingency plans in place, such as identifying alternative suppliers or increasing safety stock during periods of known supply chain volatility.
It is normally calculated as the forecast usage during the replenishment lead time plus safety stock. In the EOQ (Economic Order Quantity) model, it was assumed that there is no time lag between ordering and receipt of materials. By accurately predicting when stock needs replenishing, businesses can maintain efficient operations, meet customer demand consistently, and manage storage costs effectively. Assume that a company has determined that the reorder point for its Product X is 80 units and its economic order quantity is 400 units. When the inventory level of Product X drops to 80 units, the company places an order for 400 units.
This will effectively warn you when you need to start on a new purchase order. Safety stock is similar to a reorder point, but it’s a surplus quantity to ensure you don’t run completely out of stock if there are delays. It’s based on your purchase and sales cycles, and it varies which one of these would not be a factor in determining the reorder point? by product. However, once you have a handle on the patterns of a product, you’re ready to start putting the variables together. If your baseball bat supplier is in China, for example, your order lead times in January or February are likely to be thrown off by Chinese New Year.
For example, real-time inventory tracking allows staff to see what’s in stock, what’s on order, and where each item is located. Software tools can also collect and present data on purchase orders, sales fulfillment, and demand forecasting on a single user dashboard. The reorder point calculation takes into account delivery lead time from suppliers. By keeping track of average delivery lead time, you can identify your most reliable and least reliable suppliers and make more informed procurement decisions.
Many business owners and managers view ROP as a somewhat mystical figure, hard to pinpoint accurately, potentially leading to either overstocking or understocking. This ambiguity arises from the challenges in accurately predicting market demand and supply chain inconsistencies. If you have at least one procurement cycle and one sales cycle worth of data, you can start using the reorder point formula to improve your inventory operations. Therefore, the manufacturer should reorder this component when stock falls to 150 units. By doing so, the company can prevent stockouts and avoid dipping into safety stock while they wait for new stock to arrive.
This is easily done using inventory management software that tracks everything you need to know about your inventory. Let’s say a manufacturer used 10 units of a component on their busiest day of production. The longest time it would take the supplier to deliver this component is 15 days.

Remember, the goal of setting safety stock is to strike a balance between the cost of carrying extra inventory and the risk of stock outs. By carefully considering these factors and balancing them against each other, you can determine an optimal level of safety stock that minimizes risks without unnecessarily tying up capital and resources. The manufacturer should hold 132 safety stock units to avoid bottlenecks in production. By reordering a predetermined amount of replenishment inventory according to demand forecasts, you can avoid sunk costs from inventory shrinkage and obsolescence.
