What is the significance of safety stock?

3. Prevent disruptions in manufacturing or deliveries – The purpose of safety stock is to make sure your customer service levels stay high – and your supply chain runs smoothly.

Manage and Calculate Safety Stock With Inventory Management Software – Many supply chain managers rely on inventory management software and built-in or complementary demand planning tools to calculate optimal safety stock levels and reduce the chances of having too much — or not enough — buffer inventory.

  • Businesses can also centralize supply chain functions on an enterprise resource planning (ERP) system for better planning and collaboration between operational units.
  • Advanced analytics capabilities offered by leading ERP software can improve forecasts’ reliability, accounting for demand and supply fluctuations.

That reduces the chances of holding excess safety stock and can reduce the need for safety stock by optimizing inventory management across the board. In short, this software can perform every task required to calculate and manage safety stock accurately and improve overall operational efficiencies.

How do you analyze a safety stock?

To calculate safety stock, work out your average daily use for a product and multiply it by its average lead time – how long it takes, in days, to arrive once you place an order. Then subtract this number from your maximum daily use times your maximum lead time. The result is the safety stock number for that product.

Inventory = Lead-time Demand + Safety Stock.

As the customer is waiting for you to make the product, you carry no inventory other than the work-in-process over the waiting time. And definitely no safety stock other than the raw material needed to make the product. So Finished goods inventory is nearly always zero.

  • Negative Safety stock does not mean negative inventory.
  • That could be an accounting mistake and a nightmare.
  • The tax authorities and the Accounting regulators may come after you if you show negative inventory in your books.
  • Negative Safety stock implies you are carrying an order backlog or unfilled orders.

Orders ready to be filled and waiting perhaps with a check ready to be deposited in the bank like in the case of Boeing. Customer service costs money. Higher service levels require more precision in your demand signals and/or higher safety inventory. Inventory is not cheap and can burn cash and make you less profitable.

If your targeted service level is 95% and you are providing 100% service level already, it may be time to stock out for some time to average down. right? Here is an invitation to the supply chain planners who want to learn the details of this challenge and understand Inventory Optimization.

Is a high or low margin of safety good?

Compute the margin of safety

The margin of safety is the difference between actual sales and the break even point. Now that we have calculated break even points, and also done some target profit analysis, let’s discuss the importance of the margin of safety. This amount tells us how much sales can drop before we show a loss.

A higher margin of safety is good, as it leaves room for cost increases, downturns in the economy or changes in the competitive landscape. If you remember back to our example with our friends at Monte Corporation and the widgets, when a new competitor came into the market, it created a crisis! The formula used to calculate the margin of safety \text =\text -\text We can take this formula one step further to figure the margin of safety percentage \text =\dfrac } } Now let’s look at an example: Let’s go back to our kayaks.

Remember our basic information:

Price per kayak $500
variable costs per kayak $225
Contribution margin per kayak $275
Fixed costs/month $7,700

Also, remember, Minnesota Kayak Company needs to sell 28 kayaks at $500 each to break even. So in this example, $14,000 in sales is their break even point. Let’s assume their current sales of kayaks is 50 kayaks per month at $500 each, so $25,000. Using the formulas above, what is their margin of safety? \$25,000-\$14,000=\$11,000 is their margin of safety.

What is their margin of safety percentage? \dfrac =44\% is their margin of safety percentage. We can check our calculations, by multiplying the margin of safety percentage of 44% by actual sales of $25,000 and we end up with $11,000. So the margin of sales percentage tells us that Minnesota Kayak Company can sell 44% fewer dollars worth of kayaks and still break even.

The higher the margin of safety percentage, the better!

Is having a high margin of safety good?

What is a good margin of safety percentage? – Generally speaking, the higher your margin of safety, the better. The value represented by your margin of safety is your buffer against becoming unprofitable, which will vary depending on your business. For example, if your margin of safety is around $10,000 but your selling price per unit is $5,000, that means you can only lose a sale of two units before your business is in serious trouble.

This means if Company A is selling a unit at $100 each, the formula might look like this:

($200,000 – $100,000) / $100 = 1000 That gives a buffer of 1000 units before the business becomes unprofitable, i.e., Company A could lose 1000 sales and still break even, and those 1000 sales above break even directly translate into profit. Businesses can use this information to decide if they want to expand or reevaluate their, it can also help them decide how secure they are moving forwards.

What is another name for safety stock?

Buffer Stock vs Safety Stock – The terms ‘safety stock’ and ‘buffer stock’ are often used interchangeably. Both describe the extra stock retailers use as a cushion for unexpected demand or uncertainties within the supply chain. Still, in some cases, there is a slight difference between the two.

For instance, buffer stock can refer to inventory that’s specifically held for an abrupt increase in demand (like when your marketing brings in even more business than you’d anticipated). Safety stock, on the other hand, can refer to inventory that’s held in case of supplier delays (like when there’s a manufacturing shutdown or a shortage of raw materials).

Despite these nuanced definitions, safety stock and buffer stock share the same end goal: to ensure you have enough available inventory to meet demand and ship on-time orders.

What is the disadvantage of holding too much safety stock?

Excess inventory can lead to poor quality goods and degradation – If you’ve got high levels of excess stock, the chances are you have low inventory turnover, which means you’re not turning all your stock on a regular basis. Unfortunately, excess stock that sits on warehouse shelves can begin to deteriorate and perish.

Advantages of Safety Stock – Safety stock can minimize the impact of a shortage. When you have a shortage but do not have enough safety stock, you will face a severe problem. In other words, safety stock works as an “insurance” against shortages. Safety stock makes it easier to respond to changing demand levels because you have more flexibility when orders are placed.
