Reorder Point Formula: How Your Business Can Use It



reorder point formula calculator

In other words, setting a reorder point can help you reduce holding costs. For example, if your ROP for a certain chair is 15, you should order more chairs from your supplier when you have only 15 left in stock. By the time you sell the remaining chairs, your stock will be replenished. An accurate ROP allows you to avoid both a stockout and overstocking.

  • It’s a vital part of calculating your optimal economic order quantity.
  • Now we’ll plug the figures from our example into the reorder point formula.
  • For example, if your ROP for a certain chair is 15, you should order more chairs from your supplier when you have only 15 left in stock.
  • The your vendor takes to supply the items, the more sales you’ll be losing.
  • It is a vital number for any inventory control manager (see inventory control manager salary) to calculate.
  • It’s based on your purchase and sales cycles, and it varies by product.
  • This reorder point calculator is used to calculate the level to which inventory is allowed to fall before a purchase order for further supplies is placed.

Businesses with a limited number of products can start with excel spreadsheets and format cells to turn red when inventory levels reach the reorder point. ShipBob helps ecommerce brands manage inventory, forecast demand, pack orders, reduce shipping costs, and deliver on customer expectations. Safety stock, as the name suggests, is the extra “just in case” inventory you keep on hand to anticipate variability in demand or supply. For example, if there’s a supply chain interruption, you may need to rework your formula, give more lead time, and order more often. If sales are unusually slow or impacted by seasonality, you may need to hold off on reordering.

Calculating Reorder point and Safety stock

ShipBob is an order fulfillment solution that features built-in inventory management software, giving you precise control over your inventory. You can check inventory counts at each fulfillment center and set automatic reorder levels, so you are notified when stock is running low. The purpose of calculating reorder points is to ensure you keep enough stock to satisfy your orders and never have to dip into your safety stock. In essence, there is no ideal reorder point because the formula tells you when to reorder stock for every product in your inventory. You’ll find that as you scale, implementing the formula throughout your entire product line is necessary to keep inventory levels in check. If your business doesn’t operate with a safety stock or has a high day-to-day variable with sales, don’t worry.

Setting accurate reorder points allows businesses to avoid having products out of stock while waiting for new inventory. Lead time is the second issue that may interfere with calculating your optimal reorder point. Unfortunately, you don’t have much control over lead time as it is dependent on the supplier and shipper. However, there are two ways you can prepare yourself for any issues in average lead time. That way you can still fulfill new orders and use batch picking while awaiting products in shipment. Second, calculate your reorder point daily to notice any fluctuations in lead time demand as they occur.

What Is a Reorder Point (ROP)?

Second, calculate your reorder point daily to notice any changes in lead time as they occur. This way you can order product earlier if you discover any issues when inventory forecasting. It is a vital number for any inventory control manager (see inventory control manager salary) to calculate. Reorder points help to ensure products and cash flow in the right direction, at the right time. With accurate reorder points for all of your product SKUs, you can meet customer demand in a timely fashion to improve cash flow and avoid the bloated costs of overstock.

I had to click several times, then export it, and try to make sense of it. Once the reorder point is met, some point-of-sale systems will alert you that the item is low on stock, and automatically fill a purchase order form for that item. So, calculating the reorder point for inventory is crucial to replacing orders and fulfilling the other requirements.

Benefits of Using the Reorder Point Formula (ROP)

The end result will produce an inventory quantity that will indicate when it’s time to order more. If you wait to order until you have run out of inventory, then there will be a lag between when you place the order and when you can sell your new inventory. Setting a reorder point can help you reorder in time to avoid this availability gap. No matter what your category, if you have products you can’t sell, you either have to keep paying to store them, or you need to dispose of them, which also comes with a cost. In other words, if you want to run an efficient business, you can’t rely on intuition to determine when to reorder stock. ROP is expressed as a quantity, such as 20 t-shirts or 50 apples.

An effective reorder point ensures that your business keeps flowing— it helps you fulfill orders quickly, protects your margins, and keeps customers happy. The manufacturer should hold 132 safety stock units to avoid bottlenecks in production. Next, determine the safety stock the company wishes to have on hand. In cases of emergency, this store would like 200 candy bars in safety stock.

Using the Reorder Point Calculator

Average daily usage x lead time shows you how many unit sales you can expect, which shows you how much stock you need for any given amount of time. The Reorder Point is the threshold at which you should order more products to prevent shortages while also avoiding
overstock. But remembering the reorder point formula isn’t always convenient. 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. 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.

To maintain an accurate reorder point, check the underlying metrics — average daily sales/usage and average lead time — at least once per quarter. If you have a high season and low season, or seasonal bad weather that slows down deliveries, factor this in. To accurately calculate reorder points, you’ll need to have strong records on sales volume and trends over a certain time period.

One of those decisions is when you should order more supplier stock. Reorder point is just one of many critical inventory metrics you need to keep track of when you run a store. InFlow Cloud has a Recommended Reorder Point report that examines your sales data and recommends reorder points for your products. It also factors in goods in transit (GIT), which are reorder point formula calculator products that have been ordered from a vendor but haven’t been received yet. 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. Manual inventory tracking and reorder point calculation can be time-consuming, tedious, and error-prone.

  • Lead time can also be calculated for the product using a simple formula or by using a lead time calculator.
  • Your reorder point for black ballet flats in a size 7 could be 30 units, while your reorder point for black flats in a size 11 is 10 units.
  • A healthy safety stock level will help keep your business moving in these situations.
  • Recalculate your ROP whenever you experience major changes to maintain optimal stock levels.
  • 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.
  • You’ll find that as you scale, implementing the formula throughout your entire product line is necessary to keep inventory levels in check.

At the same time, not enough stock causes slow order fulfillment, the potential for missed sales, and lost revenue. But when you know your reorder point, you’re less likely to have too much cash wrapped up in inventory. You can order just enough as you need it, instead of stockpiling and spending on storage costs and inventory.

For growing retailers, manufacturers, or wholesalers, working with dozens or hundreds of spreadsheets can be time-consuming and error-prone. If your business falls into this category, consider the benefits of inventory management software. 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.
