Why is Safety Stock Important? The principal goal of safety stock is to ensure that there is sufficient product available to the customer.

P model There are two general types of multi-period inventory systems: fixed-order quantity models (alsocalled the economic order quantity, EOQ, and Q-model) and fixed-time period models (also referred to variously as the periodic system, periodic review system, fixed order interval system, and P-model).

To provide a safeguard for variation in raw material delivery time To take advantage of economic purchase-order size To maintain independence of operations To meet variation in product demand All of the above are reasons to carry inventory.

Safety stock is an additional quantity of an item held in the inventory to reduce the risk that the item will be out of stock. It acts as a buffer stock in case sales are greater than planned and/or the supplier is unable to deliver the additional units at the expected time.

Safety stock formula: How to calculate safety stock?

1. Multiply your maximum daily usage by your maximum lead time in days.
2. Multiply your average daily usage by your average lead time in days.
3. Calculate the difference between the two to determine your Safety Stock.

Even with all the AI and big data technology you invest, your forecasts will not be 100% accurate. That’s where safety stock comes in. It acts as a buffer between what you planned and what the real world sends your way. It increases the chances that you’ll meet your customer service levels consistently.

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.

The holding cost are those cost that add up when the business has finished goods in the ready to ship status but has yet to be shipped to the customer. Its important to manage this cost holding cost because the un-sold inventory is taking up space, the labor and insurance cost.

There are four main components to the carrying cost of inventory:

• Capital cost.

• Inventory service cost.

It can help you determine if production should be increased or decreased, in order to maintain the current or desired balance between income and expenses. 3. Carrying costs are typically 20 – 30 percent of your inventory value. This is a significant percentage, making it an essential cost factor to account for.

Although we have identified a number of costs associated with inventory decisions in the chapter, only two categories, carrying cost and ordering cost, are considered in the basic EOQ model.

Stockout cost is the lost income and expense associated with a shortage of inventory. When a customer wants to place an order and there is no inventory available to sell to the customer, the company loses the gross margin related to the sale.
