What’s Safety Stock Level?

As its name implies, safety stock, sometimes referred to as buffer inventory, is the emergency additional stock that a company uses in the event of unforeseen circumstances that disrupt the supply chain. Safety stock level is an inventory formulation retailers use to ascertain how much extra their stock needs along with regular quantities. Retailers do so to make sure they have enough to keep on their shelves for a particular period, usually enough time to weather the storm. While the most obvious approach is to stock more products generally, determining safety stock is significantly more complex than that. When finishing safety stock calculations, the tricky part is deciding on an amount that’s just right, not too high or too low. Too much in stock will result in a strain on finances since it ties up company capital. Too little stock might wind up being inadequate for the length of the interruption. Not to an increase in stock may lead to all manner of logistic issues like lack of storage and insufficient transportation methods Inventory typically includes two kinds of inventory: Cycle inventory and safety stock. Cycle inventory is rather straightforward, providing the buffer between when inventory is sold and sold. By way of instance, a store will often have some extras in storage just in case there’s a surge in demand for a product. This differs from a safety stock formula that covers both changes in demand and lead times.

How To Determine Safety Stock Levels

Several formulations can be used, but finally how to calculate safety stock will depend on your particular business. The two simplest calculation techniques which may be used for many retail companies are: 1. Fundamental Safety Stock FormulaThis method is based on the amount of days that a company would like to be catered for in the event of a distribution breakdown. It’s an easy method showing how to calculate safety stock with direct time.

The formula is:

Average Revenue * x Security Days = Safety Stock *Average earnings are attained by dividing sale amounts by the direct time The purpose of this calculation is to ascertain how much you’ll have to purchase from the supplier generally, i.e, your reorder inventory. So in the event that you’ve got a normal sale of 100 quantities each day for a commodity, and you wish to have 5 times of the typical sale in safety stock with a lead time of 10 times: Your security inventory will be 5 x 100 amounts: 500 quantities. Your reorder quantity is the Safety Stock + Typical Revenue x Lead time so in this case, you will reorder 500+100 x 10= 1,500 quantities.

2. Typical — Max Formula

This simple security stock formula, also called”stock equation”, is a bit more complicated than the simple system of how to calculate safety stock.

The formula used here is: Safety stock = (Maximum daily use x Maximum lead time in days) — (Typical daily use x Typical lead time in days)

By way of instance, if you have earnings over 12 months with a total of 12,000 pieces, an average per month of 1000, this means you sell about 33 pieces each day. On a good day, you can move a maximum of 39.5 pieces. For these items to be sent to you it requires your provider about 35 days, but occasionally can delay up to 40 days. Maybe they had transport difficulties, or their production is not as efficient is not as it needs to be, thus the excess time.

The formulation of the security stock: [ maximum sale (39.5 bits ) x maximum lead time (40 days) ] [ average sale (33 pieces) x average lead time(35 times ) ] Your security inventory will be 427 pieces. But remember that you must calculate stock, AKA, your purchase stage, which is always the same formula: Security stock + typical sale (or average prediction ) x average lead time: 1578

For this, we could determine your store would have to carry about 1578 bits as safety stock at all times.

The Benefits of Safety Stock

While many retailers understand how to determine safety stock level for their organization, the practice isn’t common particularly among small and midsize companies. However safety stock is essential for many businesses for several reasons:

1. Protects Against Supply Variations

We have discussed this at length, but it does not hurt to mention more ways your supply chain can break down.

Having security stock ensures that your business operations continue smoothly in spite of such hitches in the rear end.

With the excess stock in place, companies can replenish shelves without missing a beat or a client.

Frequent Pitfalls of Safety Stock Management

In spite of the formulas that simplify the way to calculate safety stock levels, setting the right inventory can be complicated.

1. Setting Safety Stock into Zero will Reduce Inventory

Having additional inventory means more capital is tied up, so sometimes business owners reduce their security stock entirely. This frees up money for other business processes. While it might seem like a simple solution for when money is tight, a supply interruption could cost your organization a whole lot more than the cost of the surplus inventory. Retailers worldwide lose $984 billion worth of earnings as a result of unavailable items.

2. With a Textbook Safety Stock Formula

There are many safety stock formulas, what you use for your company is set by your business, business size, nature of goods, etc. 1 problem inventory managers do would be to use oversimplified stock formulas without accounting for their inadequacies. By way of instance, the”Typical — Max” formula doesn’t take into account the sort of product. Additionally, it does not account for the degree of danger that comes with a few products such as perishable goods.

3. Reducing Safety Stock When Typical Supplier Lead Time Reduce

whilst safety stock is intended to prevent shortages when there’s an interruption in supply and demand, how slow or fast your provider replenishes your inventory should not change your security stock. These modifications can be interpreted to your cycle inventory but the quantity you purchase for safety stock should stay the same.

4. Safety Stock Covers for many Interruptions

there are lots of reasons for stock-outs, and anticipating your security stock to cover for each and every situation could result in inaccurate calculations. Overshooting your levels could result in excess inventory while underestimating contributes to shortages. Business owners need to attempt to balance between the two, but also accept that stock-outs are inevitable from time to time and have back up plans in place.
