## What is Marginal Cost?

Marginal cost represents the incremental costs incurred when producing additional units of a good or service. It is calculated by taking the total change in the cost of producing more goods and dividing that by the change in the number of goods produced.

The usual variable costs included in the calculation are labor and materials, plus the estimated increases in fixed costs (if any), such as administration, overhead, and selling expenses. The marginal cost formula can be used in financial modeling to optimize the generation of cash flow.

Below we break down the various components of the marginal cost formula. Image: CFI’s Budgeting & Forecasting Course.

### 1. What is “Change in Costs”?

At each level of production and during each time period, costs of production may increase or decrease, especially when the need arises to produce more or less volume of output. If manufacturing additional units requires hiring one or two additional workers and increases the purchase cost of raw materials, then a change in the overall production cost will result.

To determine the change in costs, simply deduct the production costs incurred during the first output run from the production costs in the next batch when output has increased.

### 2. What is “Change in Quantity”?

It’s inevitable that the volume of output will increase or decrease with varying levels of production. The quantities involved are usually significant enough to evaluate changes in cost. An increase or decrease in the volume of goods produced translates to costs of goods manufactured (COGM).

To determine the changes in quantity, the number of goods made in the first production run is deducted from the volume of output made in the following production run.

How do you calculate the marginal cost? Download CFI’s free Marginal Cost Calculator. If you want to calculate the additional cost of producing more units, simply enter your numbers into our Excel-based calculator and you’ll immediately have the answer.

Begin by entering the starting number of units produced and the total cost, then enter the future number of units produced and their total cost.  The output of that equation is the marginal cost. Below is a screenshot of the calculator. ### An Example of the Marginal Cost Formula

Johnson Tires, a public company, consistently manufactures 10,000 units of truck tires each year, incurring production costs of \$5 million. However, one year finds the market demand for tires significantly higher, requiring the additional production of units, which prompts management to purchase more raw materials and spare parts, as well as to hire more manpower.

This demand results in overall production costs of \$7.5 million to produce 15,000 units in that year. As a financial analyst, you determine that the marginal cost for each additional unit produced is \$500 (\$2,500,000 / 5,000).

### How Important is Marginal Cost in Business Operations?

When performing financial analysis, it is important for management to evaluate the price of each good or service being offered to consumers, and marginal cost analysis is one factor to consider.

If the selling price for a product is greater than the marginal cost, then earnings will still be greater than the added cost – a valid reason to continue production. If, however, the price tag is less than the marginal cost, losses will be incurred and therefore additional production should not be pursued – or perhaps prices should be increased. This is an important piece of analysis to consider for business operations.

### What Jobs Use the Marginal Cost Formula?

Professionals working in a wide range of corporate finance roles calculate the incremental cost of production as part of routine financial analysis.  Accountants working in the valuations group may perform this exercise calculation for a client, while analysts in investment banking may include it as part of the output in their financial model.

### Video Explanation of Marginal Cost

Below is a short video tutorial that explains what marginal cost is, the formula to calculate it, and why it’s important in financial analysis.

Video: CFI’s Financial Analysis Courses.

### Economies of Scale (or Not)

Businesses may experience lower costs of producing more goods if they have what are known as economies of scale.  For a business with economies of scale, producing each additional unit becomes cheaper and the company is incentivized to reach the point where marginal revenue equals marginal cost.

### Marginal Costing Question 1 Detailed Solution

Marginal Costing: Marginal cost is a technique of cost analysis wherein the marginal cost i.e. the variable cost is charged to units of cost, while the fixed cost for the period is completely written off against the contribution.

Note that variable costs are those which change as output changes - these are treated under marginal costing as costs of the product. Fixed costs, in this system, are treated as costs of the period.

Marginal costing is a technique of analysis and presentation of costs that helps management in taking many managerial decisions and is not an independent system of costing such as process costing or job costing.

Marginal cost implies the additional cost involved in producing an extra unit of output, which can be reckoned by the total variable cost assigned to one unit.

In marginal costing, all costs are divided into fixed and variable.

Break-even analysis is an integral and important part of marginal costing.

When valuing the finished goods and work in progress, only variable costs are taken into account but the variable selling and distribution overheads are not included in the valuation of inventory.

It is calculated as Marginal cost = Direct Material + Direct Labour + Direct Expenses + Variable Overheads.

Therefore, statements (ii) and (iv) are true.

### Marginal Costing Question 2:

When labour is plotted on X-axis and capital is plotted on Y-axis and an iso-quant is prepared, then which of the following statements is/are false ?

(a) Marginal rate of technical substitution of labour for capital is equal to the slope of the iso-quant.

(b) Marginal rate of technical substitution of labour for capital is equal to change in the units of capital divided by the change in the units of labour.

(c) Marginal rate of technical substitution of labour for capital is the ratio of marginal productivity of capital to marginal productivity of labour.

(a) and (b) statements

Only (c) statement Only (a) statement Only (b) statement

Option 2 : Only (c) statement

### Marginal Costing Question 2 Detailed Solution

The marginal rate of technical substitution:

The marginal rate of technical substitution (MRTS) is an economic theory that illustrates the rate at which one factor must decrease so that the same level of productivity can be maintained when another factor is increased.

The marginal rate of technical substitution shows the rate at which you can substitute one input, such as labor, for another input, such as capital, without changing the level of resulting output.

The MRTS is equal to the slope of isoquants.The marginal rate of technical substitution of labor for capital is equal to change in the units of capital divided by the change in the units of labor. ​​MRTS = - ΔK / Δ, Where K = Capital and L = Labor.The marginal rate of technical substitution of labor for capital is the ratio of marginal productivity of labor to the marginal productivity of capital.MRTS = MPL / MPK .Thus, statement C is incorrect.

### Introduction to Marginal Cost and Marginal Costing

Marginal Cost: The term Marginal cost means the additional cost incurred for producing an additional unit of output. It is the addition made to total cost when the output is increased by one unit. Marginal cost of nth unit = Total cost of nth unit- total cost of n-1 unit.

E.g. When 100 units are produced, the total cost is Rs. 5000.When the output is increased by one unit, i.e., 101 units, total cost is Rs.5040. Then marginal cost of 101th unit is Rs. 40[5040-5000]

Marginal Costing: It is the technique of costing in which only marginal costs or variable are charged to output or production. The cost of the output includes only variable costs.

Fixed costs are not charged to output. These are regarded as ‘Period Costs’. These are incurred for a period. Therefore, these fixed costs are directly transferred to Costing Profit and Loss Account.

### Introduction to Absorption costing

As the name suggests, absorption costing is the method of costing in which the entire cost of manufacturing a product or providing a service is absorbed in it.

In contrast to the variable costing (Activity based costing) method, it includes both fixed and variable costs for absorption in addition to the direct costs.

As all the costs incurred are absorbed, this method is also sometimes referred to as Full absorption costing or Total absorption costing (TAC).
