Demand vs Quantity Demanded: Difference and Comparison

We all read economics in our early school days. The concept of functions of banks, demand and supply, and many more were taught to develop a basic understanding of the person with respect to the economic system of a country.

But some of these concepts become really confusing if not explained well. 

The prime examples of such concepts are the concept of Demand and Quantity Demanded. While these two are widely used interchangeably, their wrong use can create havoc in certain situations.

Non-arguably, these terms are very related to one another but still carry a lot of distinctions. Therefore, it becomes crucial for one to know the exact differences that lie between these two. 

Key Takeaways

  1. Demand represents the overall relationship between the price of a good and the quantity consumers are willing to buy. In contrast, quantity demanded refers to the specific amount purchased at a given price.
  2. Demand is depicted as a curve on a graph, while quantity demanded is a single point on that curve.
  3. Changes in demand result from factors such as consumer preferences or income, whereas changes in quantity demanded are primarily caused by price fluctuations.

Demand vs Quantity Demanded 

The difference between Demand and Quantity Demanded is that the former refers to the intention or willingness showed by a buyer with respect to buying any goods or service at any price as determined by the market or the seller, but on the contrary, Quantity Demanded refers to the exact number or amount that the customer intends to buy for a particular price only.

Demand, in simple words, denotes the quantity or amount of any goods or service which the customer intends to buy at any given price. This is counted for a specific period of time, like a month or a year.

It can be shown on a graph in which the two axes happen to be the price of the goods and the quantity of the goods. 

On the contrary, the Quantity Demanded is just a point on the demand graph that we mentioned earlier. It is the one point at which a specific quantity is being demanded a specific amount at a specific time period.

Unlike Demand, this is a more definite concept and clarifies the on-point willingness and capacity of a person to buy a certain thing.

What is Demand? 

Demand, in simple words, denotes the quantity or amount of any goods or service which the customer intends to buy at any given price.

This can be affected by many features such as income, inflation, etc., and makes it really easy for one to understand the economic dynamics of a certain place. 

It appears like a line on which multiple quantities for different prices exist. The Quantity Demanded is a point that exists in this concept.

It reflects all the available quantities demanded at different price levels and time periods. It also defines in what way people are ready to spend their money on the destined goods. 

This concept is mostly affected by things other than price, such as the income, etc. of the buyer. Not only this, but the change in the taste and preferences of the consumer brings a change in demand as well. If the demand changes, it will affect the shape of the demand curve eventually.

What is Quantity Demanded? 

Quantity Demanded is just a point on the demand graph that we mentioned earlier. It is the one point at which a specific quantity is being demanded a specific amount at a specific time period.

This point denotes the exact amount that is desired by the consumer and the exact price that the consumer is willing to pay. 

It appears like a dot on the demand graph and represents only one particular quantity. This point exists on a line called Demand.

It reflects only one particular quantity for a particular price and specific time period. This point happens to be a tiny piece of the puzzle. 

As far as the effects of this concept are concerned, this can be affected by the price of the goods or services only. Change in the Quantity Demanded will bring not only a difference in shape but a movement in the demand curve also.

And all these changes, as a result, alter the demand graph from its original position.
