What Is the Reorder Point and How Do You Calculate It?

The reorder point is the stock level that tells you to order again. Learn the reorder point formula, how lead time drives it, and how it uses safety stock.

What Is the Reorder Point and How Do You Calculate It?

TL;DR: The reorder point is the stock level at which you place a new order. Work it out by adding two things: the demand you expect during your supplier’s lead time, plus your safety stock. Hit that level and it is time to reorder, so fresh stock arrives before you run dry.

Knowing how much buffer to hold is only half the job. You also need to know the moment to act. That moment is the reorder point: the line on the shelf that says “order now”. Set it well and stock flows without gaps or pile-ups, whether you are dispatching parcels to shoppers or fulfilling bulk orders for trade buyers.

What is a reorder point?

A reorder point is the stock level that triggers a new purchase order. Netstock explains that it tells planners exactly when to replenish, so you neither reorder too late and cause a stockout nor too early and tie up cash. Each product has its own reorder point, because each one sells at its own pace and comes from a supplier with its own lead time.

What is the reorder point formula?

The formula is simple: reorder point = (average daily demand x lead time) + safety stock. As inFlow sets out, you multiply how much you sell per day by how many days a refill takes, then add your safety buffer on top. The first part covers normal sales while you wait for stock; the safety stock covers the days that do not go to plan.

Here is a quick example. If you sell 12 units a day, your supplier takes 7 days, and you hold 30 units of safety stock, your reorder point is (12 x 7) + 30, which is 114 units. When stock drops to 114, you place the order.

How is the reorder point different from safety stock?

Safety stock and the reorder point work together but do different jobs. Safety stock is a quantity: the cushion you hold for bad weeks. The reorder point is a trigger: the level that tells you to act. Netstock notes the two are not interchangeable, since the reorder point includes safety stock inside it but also adds the sales you expect during the wait. If you want to size the cushion itself, that is a separate safety-stock calculation in its own right.

Why does lead time drive your reorder point?

Lead time is the gap between placing an order and receiving it, and it is the biggest lever in the formula. A longer lead time means more sales happen while you wait, so the reorder point climbs and you must act sooner. This is why imported goods and long supplier chains push reorder points higher. It also explains why a shorter, more reliable supply route lets you hold less and reorder later, freeing up cash and space.

What happens if you set your reorder point wrong?

Getting the level wrong cuts both ways. Set it too low and stock runs out before the refill lands, so you miss sales and leave trade orders unfilled. Set it too high and you reorder too early, stacking up stock that ties up cash and fills shelf space you could use for faster lines. The aim is a level that lands fresh stock just as the old stock runs low. Because demand and lead times drift, a reorder point that was right last quarter can be wrong this one, which is why the figure needs a regular look rather than a single setting.

How do reorder points work across a large catalogue?

Setting one reorder point is easy. Setting hundreds, and keeping them current as demand and lead times shift, is where it gets hard. A high-SKU catalogue needs each line watched and each trigger updated, or the maths quietly goes stale. This is a real strain for any team managing a deep catalogue, online or B2B, and it is where system support earns its keep.

Reorder points when you outsource fulfilment

A reorder point is only as good as the numbers behind it. You need live stock counts and accurate lead times, or the trigger fires at the wrong moment. A logistics partner that receives, stores and dispatches your goods in one connected system keeps those figures current, so reorder points reflect what is actually on the shelf. Juvo holds your stock across a French warehouse network and shows real-time levels through a single platform, which is exactly the visibility a reliable reorder point needs. Day-to-day topping up then sits with your stock management setup.

Frequently asked questions

What is a reorder point? A reorder point is the stock level that tells you to place a new order. When on-hand stock falls to that level, you reorder so that fresh inventory arrives before you run out.

What is the reorder point formula? Reorder point = (average daily demand x lead time) + safety stock. You multiply daily sales by the supplier’s lead time to cover normal demand during the wait, then add safety stock for demand spikes and delays.

Does the reorder point include safety stock? Yes. Safety stock is one of the two inputs. The reorder point adds it to the demand expected during lead time, so the trigger already accounts for the buffer you want to keep in reserve.

How does lead time affect the reorder point? A longer lead time raises the reorder point, because more sales happen while you wait for stock. Shorter, steadier lead times let you hold less and reorder later.

How often should reorder points be updated? Update them whenever demand or supplier lead times change, and review the whole catalogue each season. Triggers based on outdated figures cause both stockouts and overstocking.
