- COST AND REVENUE ANALYSIS
Cost Analysis
Cost analysis is the process of examining the different costs associated with a business or product. It can be used to identify areas where costs can be reduced, improve profitability, and make better pricing decisions.
There are three main types of cost analysis:
Cost Breakdown Structure (CBS): A CBS is a hierarchical breakdown of all the costs associated with a project or product. It is typically used in project management and engineering.
Cost Breakdown Structure (CBS)
Value Chain Analysis: A value chain analysis is a tool that helps businesses identify the activities that add value to their products or services. It can be used to identify areas where costs can be reduced or efficiency can be improved.

Activity-Based Costing (ABC): ABC is a costing method that assigns costs to activities rather than to products or services. It can be used to improve the accuracy of cost estimates and make better pricing decisions.
Revenue Analysis
Revenue analysis is the process of examining the different sources of revenue for a business. It can be used to identify areas where revenue can be increased, improve profitability, and make better marketing decisions.
There are three main types of revenue analysis:
Sales Trend Analysis: A sales trend analysis is a study of the historical sales data of a business. It can be used to identify trends and patterns in sales, such as seasonal fluctuations or the impact of marketing campaigns.

Customer Profitability Analysis: A customer profitability analysis is a study of the profitability of different customer segments. It can be used to identify the most profitable customers and to target marketing efforts accordingly.
Customer Profitability Analysis
Product Profitability Analysis: A product profitability analysis is a study of the profitability of different products or services. It can be used to identify the most profitable products and to make pricing and product development decisions.
By understanding the different types of cost and revenue analysis, businesses can make better decisions about how to improve their profitability.
1.1 Meaning of Cost
The word “cost” can have different meanings depending on the context in which it is used.
Economic cost: The economic cost of something is the value of the resources that are sacrificed in order to produce it. This includes both the explicit costs, such as the money paid for labor and materials, and the implicit costs, such as the opportunity cost of using those resources for something else.
Accounting cost: The accounting cost of something is the amount of money that is spent on it, as recorded in the financial statements of a business. This can be different from the economic cost, because it may not include all of the implicit costs.
Opportunity cost: The opportunity cost of something is the value of the next best alternative that you could have chosen to do with your time or resources. For example, the opportunity cost of going to college is the money that you could have earned if you had gone to work instead.
Sunk cost: A sunk cost is a cost that has already been incurred and cannot be recovered. For example, the money that you paid for a plane ticket is a sunk cost, even if you decide to cancel your trip.
Marginal cost: The marginal cost of something is the cost of producing one additional unit of it. This is important for businesses to know, because it can help them to decide how much to produce in order to maximize their profits.
Transaction cost: The transaction cost of something is the cost of making a deal or exchange. This can include things like the cost of finding a buyer or seller, the cost of negotiating a price, and the cost of paying taxes.
Types of Cost Diagram
- Concepts of Cost – Money Cost, Real Cost, Opportunity Cost
Fixed costs: These are costs that do not change with the level of production or output. Examples of fixed costs include rent, insurance, and salaries.
fixed cost diagram
Variable costs: These are costs that change with the level of production or output. Examples of variable costs include raw materials, labor, and utilities.
variable cost diagram
Total costs: These are the sum of all fixed and variable costs.
Average cost: This is the total cost divided by the level of production or output.
Marginal cost: This is the additional cost of producing one more unit of output.
Direct costs: These are costs that can be easily traced to a particular product or service. Examples of direct costs include raw materials and labor.
Indirect costs: These are costs that cannot be easily traced to a particular product or service. Examples of indirect costs include rent and utilities.
Outlay costs: These are costs that involve a cash payment. Examples of outlay costs include the purchase of equipment or the payment of wages.
Implicit costs: These are costs that do not involve a cash payment. Examples of implicit costs include the opportunity cost of using your own time and resources.
Sunk costs: These are costs that have already been incurred and cannot be recovered. Examples of sunk costs include the purchase of equipment that is no longer being used.
The different types of costs can be used to calculate different measures of profitability, such as profit margin and return on investment. They can also be used to make a variety of business decisions, such as pricing, production, and marketing.
The concept of cost is multifaceted and can be categorized in different ways depending on the context
1. Explicit vs. Implicit Costs:
Explicit costs: These are the actual monetary outlays incurred by a business or individual, such as wages paid to employees, rent for office space, or raw materials purchased for production. They are directly recorded in the accounting books.
Explicit Cost
Implicit costs: These are the opportunity costs associated with using resources that could have been used for other purposes. For example, the owner of a business who works for free incurs an implicit cost in the form of the salary they could have earned elsewhere. Implicit costs are not recorded in the accounting books.
Implicit Cost
2. Fixed vs. Variable Costs:
Fixed costs: These are costs that remain constant regardless of the level of production or activity, such as rent, insurance, and salaries for administrative staff. They are depicted as a horizontal line on a graph.
Fixed Cost
3. Total, Average, and Marginal Costs:
Total cost (TC): This is the sum of all fixed and variable costs at a given level of production or activity. It is represented by a curve on a graph, starting from the fixed cost level and increasing as production or activity increases.
Total Cost
Average cost (AC): This is the total cost divided by the level of production or activity. It is represented by a U-shaped curve on a graph, initially decreasing as production or activity increases due to economies of scale, and then increasing as production or activity continues to increase due to diseconomies of scale.
Average Cost
Marginal cost (MC): This is the additional cost of producing one more unit of output. It is represented by the slope of the total cost curve at any given point.
4. Accounting vs. Economic Costs:
Accounting costs: These are the costs that are explicitly recorded in the accounting records of a business, such as the purchase price of equipment or the wages paid to employees.
Accounting Cost
Economic costs: These are the total costs of production, including both accounting costs and implicit costs. They represent the true opportunity cost of using resources in a particular activity.
5. Direct vs. Indirect Costs:
Direct costs: These are costs that can be easily traced to a specific product or service, such as the raw materials used to produce a chair or the wages of a salesperson who sells only one product.
Direct Cost
Indirect costs: These are costs that cannot be easily traced to a specific product or service, but are necessary for the overall operation of the business, such as rent, utilities, and administrative salaries. They are allocated to products or services based on some method, such as the number of units produced or the amount of revenue generated.
Indirect Cost
This is not an exhaustive list of all the different types of cost concepts, but it provides a basic framework for understanding the different ways in which costs can be categorized. The specific types of costs that are relevant to a particular situation will depend on the context and the purpose of the analysis.
There are many different ways to categorize costs, depending on the context and purpose.
By how they are measured:
Explicit costs: These are costs that involve a cash outlay, such as wages, rent, and materials.
Implicit costs: These are costs that do not involve a cash outlay, but represent the value of something that is given up. For example, the opportunity cost of starting your own business is the salary you could be earning if you were working for someone else.
By their relationship to production:
Fixed costs: These are costs that do not change with the level of production, such as rent, insurance, and salaries of administrative staff.
fixed cost graph
Variable costs: These are costs that vary with the level of production, such as raw materials, direct labor, and utilities.
variable cost graph
Semi-variable costs: These are costs that have both fixed and variable components, such as electricity bills, which may have a fixed monthly charge plus a variable charge based on usage.
By their traceability:
Direct costs: These are costs that can be easily traced to a specific product or service. For example, the cost of the raw materials used to make a chair is a direct cost of the chair.
Indirect costs: These are costs that cannot be easily traced to a specific product or service. For example, the cost of rent for a factory is an indirect cost of the products that are made there.
Other important cost concepts:
Marginal cost: The marginal cost of producing one more unit of output.
Average cost: The total cost of producing a given level of output divided by the number of units produced.
Sunk cost: A cost that has already been incurred and cannot be recovered.
Opportunity cost: The benefit that is given up when one choice is made over another.
The concept of “real cost” is a bit more complex. It refers to the total cost of something, including both the explicit and implicit costs. For example, the real cost of driving a car includes not only the cost of gas, oil, and maintenance, but also the cost of insurance, depreciation, and the time you spend driving.
cost concept diagram
Types of Cost Concepts:
Outlay Costs vs. Opportunity Costs:
Outlay Costs: These are the actual monetary expenses incurred when producing or purchasing a good or service. They are easily quantifiable and directly measurable. Examples include the cost of raw materials, labor, rent, and utilities.
Opportunity Costs: These are the potential benefits or profits that are sacrificed when one choice is made over another. They are not directly measurable but represent the value of the best forgone alternative. For example, the opportunity cost of going to college is the income you could have earned if you had entered the workforce instead.
Opportunity Cost vs Outlay Cost
Accounting Costs vs. Economic Costs:
Accounting Costs: These are the costs that are recorded in a company’s financial statements. They follow Generally Accepted Accounting Principles (GAAP) and may not reflect the full economic cost of production. For example, depreciation of equipment is an accounting cost, but the equipment’s full value is not used up in one year.
Economic Costs: These are the total costs of production, including both accounting costs and implicit costs (opportunity costs). They represent the true value of all resources used in production, regardless of whether they are explicitly paid for.
Direct/Traceable Costs vs. Indirect/Untraceable Costs:
Direct/Traceable Costs: These are costs that can be easily identified and assigned to a specific product or service. For example, the cost of the wood used to make a table is a direct cost of the table.
Indirect/Untraceable Costs: These are costs that are shared by multiple products or services and cannot be easily assigned to any one of them. For example, the cost of rent for a factory is an indirect cost of all the products produced in the factory.
Incremental Costs vs. Sunk Costs:
Incremental Costs: These are the additional costs that are incurred when making a decision. They are relevant to future decisions and should be considered when evaluating alternatives. For example, the incremental cost of adding a new product line is the additional cost of production, marketing, and distribution.
Sunk Costs: These are costs that have already been incurred and cannot be recovered. They are irrelevant to future decisions and should not be considered when evaluating alternatives. For example, the cost of developing a new product that has not yet been launched is a sunk cost.
Private Costs vs. Social Costs:
Private Costs: These are the costs that are borne by the producer of a good or service. They include outlay costs and opportunity costs.
Social Costs: These are the costs that are borne by society as a whole, in addition to the private costs. They include the negative externalities associated with production, such as pollution or traffic congestion.
Opportunity Cost Diagram:
An opportunity cost diagram can be used to visualize the trade-off between two choices. The X-axis represents the amount of one resource used, and the Y-axis represents the amount of the other resource that could be obtained. The curve on the graph shows the maximum amount of the second resource that can be obtained for each level of the first resource.
Opportunity Cost Diagram
The point where the two lines intersect is the efficient point, where the marginal benefit of each resource is equal. Any other point on the graph represents an inefficient allocation of resources, where more of one resource could be obtained without giving up any of the other resource.
- Types of Cost – Total Cost, Average Cost and Marginal Cost
Types of Costs:
Fixed Costs (FC): These are costs that remain the same regardless of the level of output. Examples include rent, salaries, insurance, and depreciation. In the diagram, fixed costs are represented by a horizontal line at the top of the graph.
fixed cost graph
Variable Costs (VC): These are costs that change with the level of output. Examples include raw materials, labor, and utilities. In the diagram, variable costs are represented by an upward-sloping line that starts at zero and increases as output increases.
variable cost graph
Total Cost (TC): This is the sum of fixed costs and variable costs. In the diagram, total cost is represented by a curve that starts at the level of fixed costs and increases as output increases, eventually intersecting the average total cost curve at the minimum point.
total cost graph
Average Total Cost (ATC): This is the total cost divided by the level of output. In the diagram, average total cost is represented by a U-shaped curve that starts at a high point, falls to a minimum point, and then rises again.
average total cost graph
Marginal Cost (MC): This is the additional cost of producing one more unit of output. In the diagram, marginal cost is represented by a curve that starts below the average total cost curve, intersects it at the minimum point, and then rises above it.
marginal cost graph
Here’s a diagram that shows the relationship between fixed costs, variable costs, total cost, average total cost, and marginal cost:
total cost curve with all labels
As you can see, the different types of costs interact with each other in different ways. Understanding these relationships can help businesses make better decisions about pricing, production, and other important areas.
Fixed costs are costs that do not change with the level of production or output. Examples of fixed costs include rent, salaries of permanent employees, and depreciation of equipment.
Variable costs are costs that vary with the level of production or output. Examples of variable costs include raw materials, labor costs for temporary workers, and utilities.
Average cost is a measure of the cost per unit of production or output. It is calculated by dividing the total cost by the total quantity produced.
Average fixed cost (AFC) is the fixed cost per unit of production. It is calculated by dividing the total fixed cost by the total quantity produced. AFC decreases as the level of production increases, because the same fixed cost is spread over a larger number of units.
Average fixed cost diagram
Average variable cost (AVC) is the variable cost per unit of production. It is calculated by dividing the total variable cost by the total quantity produced. AVC may increase or decrease as the level of production increases, depending on the relationship between the variable cost and the level of production.
Average variable cost diagram
Average total cost (ATC) is the sum of AFC and AVC. It is the total cost per unit of production. ATC is U-shaped, meaning it first decreases and then increases as the level of production increases. The point at which ATC is at its minimum is called the economies of scale.
Average total cost diagram
Average cost is an important concept in business, because it can be used to determine the profitability of a product or service. If the average selling price of a product is greater than the average total cost of producing it, the business will make a profit. Conversely, if the average selling price is less than the average total cost, the business will make a loss.
- Concept of Revenue – Total revenue, Average revenue and Marginal Revenue
Total Revenue:
This is the most basic concept of revenue and refers to the total amount of money a company earns from selling its goods or services in a given period.
It is calculated by multiplying the price of each unit sold by the number of units sold.
For example, if a company sells 100 widgets for $10 each, its total revenue would be $1,000.
Total Revenue diagram
Average Revenue:
This is the revenue earned per unit of output sold.
It is calculated by dividing the total revenue by the number of units sold.
For example, if a company has a total revenue of $1,000 and sells 100 widgets, its average revenue would be $10 per widget.
Average Revenue diagram
Marginal Revenue:
This is the additional revenue earned from selling one more unit of output.
It is often used to help companies decide how much to produce and sell, as it shows how much each additional unit will contribute to the bottom line.
Marginal revenue is typically not constant, and it can be positive, negative, or zero.
Marginal Revenue diagram
Operating Revenue:
This is the revenue generated from a company’s core business activities.
It includes sales of goods and services, as well as any other income that is directly related to the company’s operations.
Operating revenue is typically the most important type of revenue for a company, as it is what drives its profitability.
Operating Revenue diagram
Non-Operating Revenue:
This is revenue generated from sources outside of a company’s core business activities.
It can include things like investment income, interest income, and gains from the sale of assets.
Non-operating revenue is often less predictable than operating revenue, and it may not be recurring.
NonOperating Revenue diagram
Types of Revenue:
Operating Revenue: This is the income generated from a company’s core business activities, such as sales of goods or services. Examples include product sales, service fees, and commissions.
Non-Operating Revenue: This is income generated from activities outside of a company’s core business, such as interest income, dividend income, and asset sales. Examples include investment gains, rental income, and proceeds from the sale of a subsidiary.
NonOperating Revenue
Average Revenue:
Average revenue is the total revenue earned divided by the number of units sold. It is a measure of the average price a company receives for each unit of its product or service.
Average Revenue Diagram
The blue line represents the demand curve, which shows the relationship between the price of a product or service and the quantity demanded. The red line represents the marginal cost curve, which shows the additional cost of producing one more unit of output. The point where the two lines intersect is the equilibrium point, where the price is equal to the marginal cost. The average revenue is represented by the shaded area above the marginal cost curve.
Understanding Revenue and Marginal Revenue
Revenue and marginal revenue are two key concepts in economics and business, but they often get confused. Let’s break down the differences and see how they fit together.
Revenue
Revenue is the total amount of money a company earns from selling its products or services. It’s calculated by multiplying the price of a product or service by the quantity sold.
Here’s the formula:
Revenue = Price x Quantity
For example, if a bakery sells 100 cupcakes at $2 each, its revenue would be:
Revenue = $2/cupcake x 100 cupcakes = $200
Marginal Revenue
Marginal revenue is the additional revenue earned by selling one more unit of a product or service. It’s different from average revenue, which is the total revenue divided by the number of units sold.
Marginal revenue is important because it helps businesses decide how much to produce and sell to maximize their profits. If the marginal revenue is greater than the marginal cost of producing an additional unit, the business should increase production. However, if the marginal revenue is less than the marginal cost, the business should decrease production.
Here’s the formula for marginal revenue:
Marginal Revenue = Change in Total Revenue / Change in Quantity
Relationship between Revenue and Marginal Revenue
The relationship between total revenue and marginal revenue is not always straightforward. In a perfectly competitive market, where there are many buyers and sellers and each seller has a small market share, the marginal revenue curve is equal to the demand curve. This means that the price a company charges for its product or service is also the marginal revenue it earns from selling one more unit.
However, in most markets, companies have some degree of market power. This means that they can influence the price of their product or service by adjusting the quantity they supply. As a company increases its production, the price it can charge for its product will typically decrease. This is because there are more buyers competing for the same product, which puts downward pressure on the price.
As a result, the marginal revenue curve will typically be below the demand curve. This means that the marginal revenue earned from selling one more unit will be less than the price of the product.
Total Revenue, Marginal Revenue
As you can see, the total revenue curve starts off increasing at a decreasing rate, reaches a maximum point, and then starts to decrease. The marginal revenue curve starts off above the average revenue curve, but eventually intersects it and falls below it.
Revenue and marginal revenue are both important concepts for understanding how businesses operate. By understanding the relationship between these two concepts, businesses can make better decisions about pricing, production, and marketing.
