What Is Marginal Resource Cost? Explanation & 7 Facts

The Marginal Resource Cost (MRC) is a measure used to determine the average cost of using a resource in comparison with the maximum value that could be produced by the resource over its lifetime. It is an important tool for determining the marginal cost of resources such as capital, labor, and energy.

What Is Marginal Resource Cost?

The marginal resource cost is the expense incurred by a corporation to acquire one unit of the resources utilized to manufacture a product. In the majority of circumstances, these additional resources are considered sources of labor, and the associated expenses are employee pay.

What Is Marginal Resource Cost?

Companies attempt to structure their operations such that their marginal resource cost, or MRC, is equal to or less than the cost of producing one more unit of output, often known as the marginal physical product, or MPP. Only when the market is regarded completely competitive does this occur.

Based on Marginal Resource Cost , How does the Company Make a Profit?

In order to generate a profit, businesses must maintain a balance between the expenses of producing their goods and the revenues generated by those items. Failure to do so is an illustration of inefficiency in business, which may cripple any prospects of success.

As a result, businesses must be aware of what it takes to acquire the labor that serves as their primary resource, particularly in terms of how the cost of labor relates to revenues. Consequently, management must be aware of the marginal resource costs incurred.

Understanding Marginal Resource Cost and Example

Simply expressed, the marginal resource cost is the cost of acquiring a single unit of resource. For example, if it costs a business $500 US Dollars (USD) to recruit a person for one hour of labor, the MRC is $500 USD. The employer would next need to determine whether or not the employee created a minimum of $500 USD worth of goods.

Obviously, it is uncommon for a corporation to be able to recruit every employee at the same salary. Therefore, the marginal resource cost must account for the various wages provided to its workers. The company’s financial health may be determined by adding together all of these factors and comparing them to the total marginal product resulting from their effort.

What Is Marginal Resource Cost?

Economists like analyzing the marginal resource costs of various businesses to determine the impact of market forces on these costs. As a result of the dominance of one or a small number of large companies, a number of marketplaces are not competitive.

For these markets, the slope of the MRC, when plotted on a graph, will swiftly increase or decrease based on product demand. This illustrates how these companies may recruit fewer workers at lower compensation than companies in a completely competitive market.

What is Marginal Cost?

Marginal cost is the extra expense spent while manufacturing more units of a product or service. It is determined by dividing the overall change in the cost of producing additional items by the total change in the number of goods produced.

The variable costs often included in the calculation include labor and materials, as well as any expected increases in fixed costs, such as administration, overhead, and selling expenditures. In financial modeling, the marginal cost formula may be used to maximize cash flow creation.

How Important is Marginal Cost in Business Operations?

When doing a financial analysis, it is essential for management to examine the price of each commodity or service given to customers; marginal cost analysis is one component to consider.

If the selling price of a product is higher than its marginal cost, then profits will continue to exceed the increased expense, which is a good justification to continue manufacturing.

What Is Marginal Resource Cost?

If, however, the price is less than the marginal cost, losses will be incurred and extra production should not be pursued; alternatively, prices may need to be raised. This is a crucial piece of analysis to consider for corporate operations.

What Jobs Use the Marginal Cost Formula?

As part of normal financial analysis, the incremental cost of manufacturing is determined by a variety of corporate finance professionals. Accountants in the valuations division may make this calculation for a client, while investment banking analysts may incorporate it as part of their financial model’s output.

What is the Formula for Marginal Cost?

The Marginal Cost Formula is:

Marginal Cost =  (Change in Costs) / (Change in Quantity)

1. What is “Change in Costs”?

Costs of production may grow or decrease at each level of production and throughout each time period, particularly when the need arises to create a greater or lesser amount of output. If the production of more units necessitates the employment of one or two additional employees and a rise in the price of raw materials, the total cost of production will be affected.

To ascertain the change in costs, just subtract the production costs incurred during the first production run from the production costs spent during the subsequent production run when output has risen.

2. What is “Change in Quantity”?

Variable production levels will inevitably result in an increase or reduction in output volume. Typically, the quantities involved are substantial enough to analyze cost changes. An increase or reduction in the number of products produced corresponds to a change in the costs of items produced (COGM).

What Is Marginal Resource Cost?

To calculate the changes in quantity, the quantity of items produced during the first production run is subtracted from the amount of goods produced during the subsequent production run.

Economies of Scale (or Not)

If a company has economies of scale, it may produce more things for less money. For a corporation with economies of scale, the production of each new unit becomes less expensive, and the organization is driven to achieve the point where marginal income equals marginal cost.

An example would be a plant that has a large amount of space capacity and gets more efficient as output volume increases. In addition, the company is able to negotiate cheaper material prices with suppliers at bigger quantities, resulting in a gradual reduction in variable expenses.

For certain firms, the cost per unit increases when more products or services are produced. These businesses are referred to as having diseconomies of scale. Imagine a business that has reached its production volume maximum.

If it wanted to manufacture additional units, the marginal cost would be very high due to the substantial expenditures necessary to increase the plant’s capacity or lease space from another business at a high price.


Marginal Resource Cost (MRC) is a measure of the value of resources used in producing output. In short, it’s the additional cost of the resource over and above what it would have cost to produce it using alternative means.

For example, if you know that the average cost of hiring someone to complete a project is $40 per hour, but you are getting paid $50 per hour for your services, you can quickly calculate the MRC on this job to find out how much you should be charging.
