# What is Revenue?

## What is Revenue?

Definition: Revenue is the total amount of money received by an organisation in return of the goods sold or services provided during a given time period.

In other words, revenue of a firm refers to the amount received by the firm from the sale of a given quantity of a commodity in the market.

For example, if a firm obtains 2, 50,000 from the sale of 10 computers, the received amount of 2, 50,000 is its revenue earned during the time period.

## Types of Revenue

What is Revenue Types? There are mainly three types of revenue:

### Total Revenue

Definition: Total Revenue (TR) of a firm refers to total receipts from the sale of a given quantity of a commodity. In other words, total revenue is the total income of a firm. Total revenue is calculated by multiplying the quantity of the commodity sold with the price of the commodity.

Formula: Total Revenue = Quantity × Price

#### Total Revenue Example

For example, if a firm sells 10 fans at a price of ₹ 2,000 per fan, then the total revenue would be calculated as follows: 10 fans × ₹ 2,000 = ₹ 20, 000

### Average Revenue

Definition: Average Revenue (AR) of a firm refers to the revenue earned per unit of output sold. It is calculated by dividing the total revenue of the firm by the total number of units sold.

Formula: Average Revenue = Total revenue / Total number of unit sold

#### Average Revenue Example

For example, if total revenue from the sale of 10 fans at the rate of 2000 per fan is ₹ 20, 000, then:

Average Revenue = 20000 / 10 = ₹ 2,000

Here, it is important to note that AR and price of a commodity are equal in value. This can be explained as follows

TR = Quantity × Price……………………..(1)
AR = TR / Q ………………………………………….(2)

Substituting the value of TR from equation (1) in equation (2),
AR = Quantity Price / Quantity
Therefore, AR = Price

### Marginal Revenue

Marginal Revenue (MR) of a firm refers to the revenue earned by selling an additional unit of the commodity. In other words, the change in total revenue resulting from the sale of an additional unit is called marginal revenue.

MRn = TRn – TRn-1

Where MRn = marginal revenue of nth unit (additional unit), TRn = total revenue from n units, TRn-1 = Total revenue from (n – 1) units and n = number of units sold.

#### Marginal Revenue Example

if the total revenue realised from the sale of 10 fans is 2,000 and that from sale of 11 fans is ₹ 2,500, then MR of the 11th fan will be calculated as follows:

MR11 = TR11 – TR10
MR11 = ₹ 2,500 – ₹ 2,000 = ₹ 500
