Understanding Marginal Cost

The term ‘marginal cost’ is pivotal for any business, particularly when it comes to making critical decisions related to production and pricing. Marginal cost simply refers to the expense incurred by a business to produce one additional unit of a product or service. Understanding the concept of marginal cost is essential to maximizing profitability and establishing an optimal production level.

The Dynamics of Marginal Cost

Marginal cost is essentially an economic principle that is founded on the law of increasing costs. This law states that as production expands, the cost to create an additional unit will eventually rise. The rationale behind this is that, as production increases, companies tend to use resources less efficiently. Business owners and managers need to understand that the key to profitability isn’t just about increasing sales volume always. At times, producing more can lead to decreasing returns. But why is that?

When businesses produce beyond their optimal capacity, they encounter additional costs. Companies often need to buy additional machinery or hire more workers, leading to additional costs that surpass the earnings generated from selling the extra output. Therefore, the marginal cost of production rises as businesses expand their output beyond the optimal level.

Let’s understand this with an example. Consider a bakery specializing in cakes. It currently produces 50 cakes a day. If the bakery decides to produce 51 cakes, the additional cost to produce that one extra cake is the marginal cost. However, if to ramp up production to 55 cakes a day, the bakery needs to buy a new oven and hire an extra worker, then the marginal cost of each of those additional cakes will be substantially higher.

Marginal Cost in Action

LinkedIn, as a popular professional networking platform, uses the concept of marginal cost in its business model. LinkedIn primarily offers two types of services to its users- free and premium. The business strategy of providing free services actually rests largely on their understanding of marginal cost.

In digital businesses like LinkedIn, the marginal cost of adding a new user to the platform is virtually zero as the digital infrastructure to support one more user is already in place. Each new user doesn’t significantly burden LinkedIn’s existing digital resources. Moreover, these additional users enhance the overall value of the network, driving more and more people to LinkedIn’s platform. This results in increased profitability largely due to the firm’s ability to keep its marginal costs low.

However, LinkedIn also offers premium, fee-based services like Premium Career, Premium Business, or LinkedIn Learning to its users. Since these services provide upgraded features and benefits that go beyond the free version, they come with a significant cost. To manage and support these additional features and ensure superior customer experience, LinkedIn needs to invest in advanced technologies, hire more specialists, and spend more on customer service. This means that the marginal cost for these premium services is significantly higher than the marginal cost for their free services. Nonetheless, the revenues generated from premium clients who are willing to pay for these high-value services more than adequately offset the increased marginal costs.

In essence, the marginal cost is a critical aspect of business strategy, helping companies make informed decisions about production, pricing, and profitability. Businesses that understand the implications of marginal cost, like LinkedIn, can use it as a graphic tool to navigate the complex business landscape and gain the upper hand over their competitors. Yet, while marginal cost can guide businesses towards profitability, it is only one piece of the puzzle. A comprehensive understanding of all aspects of a business’s costs and revenues is crucial for the sustained profitability and success of any enterprise.
