# Marginal Analysis in Business and Microeconomics, With Examples (2023)

## What Is Marginal Analysis?

Marginal analysis is an examination of the additional benefits of an activity compared to the additional costs incurred by that same activity. Companies use marginal analysis as a decision-making tool to help them maximize their potential profits. Marginal refers to the focus on the cost or benefit of the next unit or individual, for example, the cost to produce one more widget or the profit earned by adding one more worker.

### Key Takeaways

• Marginal analysis is an examination of the additional benefits of an activity compared to the additional costs incurred by that same activity.
• Marginal refers to the focus on the cost or benefit of the next unit or individual, for example, the cost to produce one more widget or the profit earned by adding one more worker.
• Companies use marginal analysis as a decision-making tool to help them maximize their potential profits.
• When a manufacturer wishes to expand its operations, either by adding new product lines or increasing the volume of goods produced from the current product line, a marginal analysis of the costs and benefits is necessary.
• The primary takeaway of marginal analysis is to operate until marginal benefit equals marginal cost; this is often the most efficient use of resources.

## Understanding Marginal Analysis

Marginal analysis is also widely used in microeconomics when analyzing how a complex system is affected by marginal manipulation of its comprising variables. In this sense, marginal analysis focuses on examining the results of small changes as the effects cascade across the business as a whole.

Marginal analysis is an examination of the associated costs and potential benefits of specific business activities or financial decisions. The goal is to determine if the costs associated with the change in activity will result in a benefit that is sufficient enough to offset them. Instead of focusing on business output as a whole, the impact on the cost of producing an individual unit is most often observed as a point of comparison.

Marginal analysis can also help in the decision-making process when two potential investments exist, but there are only enough available funds for one. By analyzing the associated costs and estimated benefits, it can be determined if one option will result in higher profits than another.

### Marginal Analysis and Observed Change

From a microeconomic standpoint, marginal analysis can also relate to observing the effects of small changes within the standard operating procedure or total outputs. For example, a business may attempt to increase output by 1% and analyze the positive and negative effects that occur because of the change, such as changes in overall product quality or how the change impacts the use of resources. If the results of the change are positive, the business may choose to raise production by 1% again, and reexamine the results. These small shifts and the associated changes can help a production facility determine an optimal production rate.

### Marginal Analysis and Opportunity Cost

Managers should also understandthe concept of opportunity cost. Suppose a manager knows that there isroom in the budget to hire an additional worker. Marginal analysis tells the manager that an additional factory worker provides net marginal benefit. This does not necessarily make the hire the right decision.

Suppose the manageralso knows that hiring an additional salesperson yields an even larger net marginal benefit. In this case, hiring a factory worker is the wrong decision because it is sub-optimal.

Because marginal analysis is only interested in the effect of the very next instance, it pays little attention to fixed start-up costs. Including those costs in a marginal analysis is incorrect and produces the so-called "sunk cost fallacy".

## How to Perform a Marginal Analysis

Marginal analysis is as simple as taking the margin benefit of an outcome and subtracting the marginal cost. However, this analysis may be difficult to assess as there are many variables and moving parts to consider. To perform a marginal analysis, you should first understand the fixed and variable costs of an activity. Because the fixed costs are not likely to change, your marginal cost will often be equal to your variable expenses.

Next, you can begin marginal analysis by finding the marginal cost and the marginal expense of an activity. Each will simply be the change in cost or benefit for every unit consumed or acquired. Note that while one aspect may remain the same (either the benefit or the cost may be constant), one aspect will often be variable.

Consider the example of consuming pizza at \$2/slice. In this example, marginal cost is easy to quantify, as every additional slice of pizza has a marginal cost equivalent to \$2. On the other hand, marginal benefit may be more difficult to quantify. If you haven't eaten all day and are hungry, you may state that the first slice of pizza you eat is worth \$10 to you. If this is the case, marginal analysis has led you the net benefit equal to the value of \$8.

To continue performing marginal analysis, consider how both the benefit and the cost will change with each slice of pizza consumed. If each slice costs \$2, your marginal cost will always be \$2. However, as you eat more pizza, you'll become full. In fact, there will be a point where you may get sick and begin to have negative marginal benefit for each additional slice eaten.

## Rules of Marginal Analysis

When performing marginal analysis, there are two profit maximization rules to consider. These two rules dictate the point at which companies should manufacture goods and allocate resources.

Do not confuse the many marginal terms used in economics; be mindful that the best quantity to operate at is when (marginal) revenue equals cost.

### Rule #1: Operate Until Marginal Cost Equals Marginal Revenue

The overarching rule of marginal analysis is that it is usually in a company's best interest to perform an activity as long as the marginal revenue is greater than the marginal cost. When marginal revenue and marginal cost are equal, there is theoretically no financial incentive for the company to continue the activity, though there may be non-financial factors to consider.

Consider a manufacturing example where it costs \$2 to make a good whose marginal revenue is \$5. For this unit, the company makes \$3. If the next unit costs \$4 to make, the company still earns a marginal profit because marginal revenue of \$5 is greater than the marginal cost. If the next unit were to cost \$6 to make, it would no longer be financially feasible to make and sell the good.

The point at which marginal revenue and marginal cost intersect is often called marginal equilibrium. It is the point at which total company profit is maximized, even if unit profit is not at its highest. In more simple terms using the pizza example above, you should continue to consume pizza as long as you think the marginal benefit you receive of each slice is worth at least the \$2 you're paying per piece.

### Rule #2: Equalize Marginal Return Across Products

Another important rule related to marginal analysis relates to companies that have different products. If a company chooses to only dedicate resources to one product, the potential marginal revenue of the other products is foregone in favor of a product likely with a diminishing marginal profit. To avoid this, every product should have an equal marginal revenue to maximize the amount of benefit obtained, especially if there are resource constraints at play.

Consider the table below outlining the marginal return received from two products. If one unit of Product A is consumed, the consumer receives a marginal benefit of 100. If a third unit of Product B is consumed, the consumer receives a marginal benefit of 30 for that third unit.

What is marginal analysis in business? ›

Marginal analysis refers to a technique of comparing the additional benefit and costs produced by an activity. The analysis result discloses whether the activity, change, or new addition is favorable to the business. It is common in decision-making and aligns with maximizing satisfaction, income, or profit.

What is marginal example? ›

Marginal cost is the added cost to produce an additional good. For example, say that to make 100 car tires, it costs \$100. To make one more tire would cost \$80. This is then the marginal cost: how much it costs to create one additional unit of a good or service.

What is marginal product in Economics with example? ›

The marginal product of a business is the additional output created as a result of additional input placed into the company. It is also referred to as marginal physical product, or MPP. In practical terms, this might mean the additional donuts produced at a donut shop once they hire an extra employee.

How do you do marginal analysis in economics? ›

This is equal to the change in total benefits divided by the change in quantity, or: Marginal benefits = (new total benefit - old total benefit) / (new quantity / old quantity) with Total benefit = sum of all marginal benefits.

What are marginal benefits examples? ›

For example: Let's say a pair of pants is being sold for \$50. However, you're willing to pay \$60 for the pair. The marginal benefit in this instance is \$60 because that's the most you're willing to pay for that pair of pants. This means the marginal benefit is \$10 higher than the actual selling price.

What is the best example of a marginal change? ›

Marginal change refers to the change that is not so vast or huge concerning the components in concern. The price of housing in Denver increased by 6 percent is a marginal change as it is the minute change compared to the changes witnessed in other options.

### How do you solve marginal analysis problems? ›

Use the marginal benefit and marginal cost you calculated to determine the marginal analysis. By subtracting the marginal costs from the marginal benefits, you can determine the net marginal benefit, which indicates whether or not the additional value of an extra unit or activity outweighs the additional costs.

What is marginal benefits and cost example? ›

For example, a marginal cost would be how much it would cost a company to produce 1 more of a good. Their marginal benefit would be the extra revenue they get from producing that one extra good.

What is managerial decision with example? ›

Managerial decisions are decisions made with regard to the operations of an organization. Some of these decisions include setting organizational goals, hiring and firing of employees and determining which products to produce and sell.
