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.

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 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 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 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.

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.

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.

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.

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.

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 Revenu
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.
