Reorder Point Guide: Formula + How to Calculate 3 ROPs
Unpredictable changes in the supply chain, such as delays or disruptions, can impact the effectiveness of your ROP strategy. While understanding ROP offers numerous benefits for inventory management, implementing it is not without its challenges. Below, we delve into the multiple benefits of utilizing ROP, highlighting how this approach can streamline your operations, reduce costs, and enhance customer satisfaction. Lead time demand is the amount of stock you use during the time it takes to receive a new order. However, by demystifying ROP, we can transform it from an enigmatic concept into a powerful, practical tool for inventory management. It’s the secret ingredient to ensuring you always have just the right amount of stock at the right time without overfilling your storeroom, or worse, running out.
First you want to determine your demand during lead time by multiplying your daily sales by the lead time. Calculating reorder points goes hand in hand with having a clear idea of purchasing trends over a given time period. You should look into customer demand so you can understand when customers are more likely to purchase your products and you can forecast demand correctly.
Advantages of the Reorder Point
Next, you need to know your delivery lead time, which simply means how long it takes for the shipment to get to you from the time you place the order. Cross reference vendors’ estimated shipping speeds with how long past deliveries have taken to reach you for the most accurate data. This figure represents how many units of this product you sell each day, on average. You should be able to find this rate, or information that can help you find it, in your point-of-sale (POS) system’s retail analytics reports. If you don’t have enough supply to meet demand, then your business will miss out on the opportunity to maximize revenue. While you can create a waitlist or pre-order system for incoming products, that creates a logistical challenge for your team.
Safety stock, as the name suggests, is the extra “just in case” inventory you keep on hand to anticipate variability in demand or supply. Inventory management software will track your inventory and alert you when you reach your SOP. For example, here is what setting up reorder points in the ShipBob which one of these would not be a factor in determining the reorder point? dashboard looks like. Unlike spreadsheets, inFlow was designed specifically for working with inventory. If you’re a spreadsheet user, you can use conditional formatting for the quantity value of specific cells. You can set Excel or Google Sheets so that cells turn red when they hit a reorder point.
Reorder point formula
Holding too much inventory ties up capital and eats into business profits with increased carrying costs. At the same time, not enough stock causes slow order fulfillment, the potential for missed sales, and lost revenue. Your ROP will be greater than your EOQ if you’re bulking up on safety stock. You may experience this prior to holiday sales or periods of seasonal demand.

If your store doesn’t maintain safety stock, then this part of the reorder point formula is optional. Overstocking also means that you’re spending more than you need to to store extra inventory. When you know your reorder point, you can have just enough inventory on hand to meet customer demand, without overspending on safety stock or holding costs. The reorder point (ROP), also reorder level (ROL) or “optimal re-order level”,[1] is the level of inventory which triggers an action to replenish that particular inventory. It is a minimum amount of an item which a firm holds in stock, such that, when stock falls to this amount, the item must be reordered.
Average daily sales
Then, subtract your lead time demand (which is average daily sales multiplied by average lead time). For starters, seasonality can drastically affect demand for your product. For example, you’re likely to sell more baseball bats right before your community’s youth baseball program starts.
For instance, a retail store might see a spike in sales during the holiday season, while a beachwear shop may experience its peak during summer months. When it comes to practical application, implementing the ROP in your business is a strategic move that can significantly enhance your inventory management. The reorder point is the quantity of units in inventory at which time an order should be placed to purchase additional units. An effective reorder point ensures that your business keeps flowing— it helps you fulfill orders quickly, protects your margins, and keeps customers happy. When the reorder point is reached, a new order of product is necessary to avoid stockouts, depending on seasonality and forecast demand. It’s important to keep adequate safety stock on-hand as demand can increase suddenly or problems with a supplier can prevent you from restocking inventory as quickly as you expected.
