Reorder Point What Is It? Formulas and Examples

Then multiply it by the days it takes between ordering a  product from your supplier and receiving it. When your inventory reaches a reorder point, it’s time to replenish that stock. By reordering before you’ve run out of inventory, you ensure you don’t have a gap in the products and services you can offer customers. “Setting a reorder point is a simple but effective way to keep inventory at a safe level. With a carefully determined reorder point, retailers can not only lower the risk of stockout, but also reduce inventory holding costs,” Miao says. First you want to determine your demand during lead time by multiplying your daily sales by the lead time.

It’s critical to recognize that your reorder point is simply a measure of the number of units needed in a replenishment order. For figuring out an optimal amount of units – and to help improve operations and reduce costs – figure out your economic order quantity. Regular audits spot trouble sooner and identify opportunities for improvements. Be mindful of increased delivery times or growing quality control issues.

Delivery notifications and tracking improve customer satisfaction by 27%.

The daily sales velocity, or the average number of units you sell per day, differs for everything you sell. Add the total delivery time (15 days ) and divide it by the number of orders (3). This means that when the t-shirt inventory drops to 250 units, the store should place a new order to replenish its stock. By using new stock following this reorder point, the store ensures that it has enough inventory to cover the lead time and any unexpected demand fluctuations. In this guide, we’ll break down the reorder point formula step-by-step, with real-world examples to help you margin of safety formula calculation example and faqs master this essential concept.

How Cross-Docking Enhances Supply Chain Efficiency

1. Based on your historical sales data, you need to determine an average of how many products you can sell in a week.
2. Check out this short clip from our new podcast for a quick rundown of reorder points and safety stock and their importance in inventory management.
3. If the lead time demand and times are inconsistent or subject to delays, businesses may need to adjust their reorder points accordingly.
4. Setting a reorder point can help you reorder in time to avoid this availability gap.

Ordering at the correct time can ensure you always meet demand, helps with inventory reduction, and streamline your inventory control. When the inventory level reaches 350 units an order should be placed for material. By the time the inventory level reaches zero towards the end of the seventh day from placing the order materials will reach and there is no cause for concern. To capture safety stock, you can input “buffer days,” which are additional days factored in with a vendor’s lead time to increase the number of units ordered. Once you have your safety stock number, you can then plug it into the reorder point formula for insight into your reorder levels.

Optimal Reorder Point & Optimal Reorder Point Formula

While it might be challenging to reach the scale of these retail giants, they provide excellent lessons in managing current stock, improving forecasting, and meeting demand. 88% of customers trust user reviews and personal recommendations in equal measure.

It means that in a normal week, the store would sell around two washing machines per day. The reorder point formula shows what happens in an ideal scenario, but things may work out differently in practice than they do in theory. Now we’ll plug the figures from our example into the reorder point formula. Knowing your ROP helps you place an order with enough time to receive, process, and restock it. Customers come around, they’re checking the shelves, they’re looking for a certain product, but you don’t have it because you didn’t order enough or didn’t receive them on time. Either you have to carry that inventory, let’s say from today to tomorrow, or let’s say from this week to next week, or this month to next month – and inventory holding is always costly.

This reorders point accounts for the daily usage during the lead time and the safety stock to buffer against any supply chain disruptions or unexpected increases in demand. The store needs to maintain an optimal inventory reorder level to avoid stockouts while minimizing holding costs. By applying the reorder point formula, the store can determine when to place a new order for t-shirts. By setting an appropriate RP, businesses can ensure they always have sufficient stock on hand to meet customer demand without tying up excessive capital in inventory.

Calculating the reorder point one day and then not revisiting it for months is unproductive. The benefit of maintaining a reliable reorder point is that it is always in line with the actual behaviour of the products. The value lies not only in the quality of its calculation but also in the frequency with which it is updated. Products stored for a long time can become obsolete , especially in industries where technology or trends change rapidly.

This automation saves time, reduces manual data entry, and minimizes the risk of errors. Additionally, some inventory management systems offer real-time visibility into supplier lead times and order status, allowing you to track your orders and plan accordingly. To help you stay on top of your inventory levels, inventory management software can generate automated reorder alerts when stock quantities reach their predetermined reorder points. These alerts notify managers or purchasing staff, prompting them to initiate the reordering process and prevent potential stockouts. Inventory management software often includes advanced analytics tools that help you optimize your inventory levels and safety stock based on your desired service level goals.

Or, in some cases, such as fresh food, you will have to literally throw away the food at the end of the day, because you cannot keep it tomorrow or next week or next month,” Nasiry says.

Conversely, it can be costly to replenish inventory when you completely run out.

Having visibility into your inventory and set reorder points helps you know when to replenish inventory to prevent stockouts before it’s too late. Using an inventory management system can provide a holistic view of your inventory and keep track of reorder points for your SKUs. Lead time can also be calculated for the product using a simple formula or by using a lead time calculator. With these three numbers in hand, it’s as simple as plugging them into the formula above to determine that product’s reorder point. This formula considers costs related to setup, production, and storage, as well as other factors that include demand. The aim is to specify the most favorable product quantity for your business that goes beyond your replenishment schedule.

This includes the time required for the supplier to take economic order quantity process the order, manufacture or prepare the goods, and ship them to the company. Lead time can vary depending on the supplier, transportation method, and other factors. But if the lead time is three days, and you know sales are on weekends, then you’d be better off using your expected sales over the next three days in your calculations. Your lead time will be higher if your supplier is overseas than in a domestic or in-house production facility. The delivery time of your shipment may vary based on the quality of your order.

For example, if you sell and deliver 10 t-shirts on average, but during weekends, you can sell as many as 15 t-shirts. Beyond overstocking or understocking, we can identify other risks that also need to be taken into account. Product shortages can destabilise distribution and marketing plans, affecting the company’s long-term planning. If demand cannot be met, opportunities to generate revenue and reach new markets or customer segments are lost. Use POS data and empirical evidence to determine when to reevaluate your ROP.
