When it comes to economics, the terms “supply” and “quantity supplied” are often used interchangeably, but they actually refer to two different concepts.
Supply is the amount of a good or service that is available in the market, while quantity supplied refers to the amount of a good or service that a producer is willing and able to provide at a certain price. We will explore the key differences between supply and quantity supplied.
Supply vs. Quantity Supplied
| Supply | Quantity Supplied |
|---|---|
| Supply refers to the amount of a good or service that producers are willing and able to offer for sale at a given price and time. | Quantity supplied refers to the specific amount of a good or service that producers are willing and able to offer for sale at a particular price and time. |
| It is determined by factors such as the cost of production, technology, the price of related goods or services, taxes and subsidies, and the number of producers in the market. | It is determined solely by the current price of the good or service being sold. |
| Supply can be elastic, inelastic, or unit elastic, depending on how responsive producers are to changes in price. | Quantity supplied is always elastic, meaning that as the price of the good or service increases, the quantity supplied will also increase, and vice versa. |
| The supply curve is upward sloping, indicating that as the price of the good or service increases, the quantity supplied will also increase. | The quantity supplied is represented by a single point on the supply curve, corresponding to the specific price and time at which the good or service is offered for sale. |
| Changes in the price of a good or service will cause a movement along the supply curve, as producers adjust the quantity supplied in response to the new price. | Changes in the price of a good or service will cause a change in the quantity supplied, as producers adjust the amount of the good or service offered for sale in response to the new price. |
| An example of supply is the amount of apples that farmers are willing and able to sell at a given price and time. | An example of quantity supplied is the 500 apples that farmers are willing and able to sell at a price of $1.50 per apple in a particular market. |

What is supply?
Supply is a term that refers to the amount of goods and services that are available in a market at a given price. It is typically measured over a period of time, such as a month or year. Supply is usually determined by the level of production, the number of sellers, and the cost of production.
Supply is the total amount of a good or service that producers are willing and able to offer for sale at a given price and within a given period. It represents the quantity of a product that producers are able to supply to the market at different price levels, holding other factors constant such as the cost of production, technology, and availability of resources.
The law of supply states that as the price of a product increases, the quantity supplied will also increase, all else being equal. Conversely, as the price of a product decreases, the quantity supplied will also decrease. The concept of supply is fundamental in understanding how prices are determined in a market economy, as it represents the willingness of producers to offer goods and services at different prices.
What is the quantity supplied?
Quantity Supplied is the amount of a good or service that producers are willing to provide at a given price in a given period of time.
Quantity supplied refers to the specific amount of a good or service that a producer is willing and able to supply at a particular price point, within a given time period. It represents the quantity of a product that a producer is willing to offer for sale at a specific price level, assuming that other factors such as the cost of production, technology, and availability of resources remain constant.
Quantity supplied is determined by the law of supply, which states that as the price of a product increases, the quantity supplied will also increase, all else being equal. Conversely, as the price of a product decreases, the quantity supplied will also decrease.
The concept of quantity supplied is important in understanding how producers respond to changes in market conditions, particularly changes in price, as it helps to determine the amount of a good or service that producers are willing and able to offer for sale at a given price level.
Differences between supply and quantity supplied
The major difference between supply and quantity supplied is that supply is the amount of goods and services a producer is willing to offer at different prices, while the quantity supplied is the exact amount of goods and services producers are willing to offer at a given price.
Supply is a theoretical concept, because it doesn’t take into account what people are actually willing to pay for goods and services. On the other hand, quantity supplied refers to the actual amount of goods and services a producer is willing to offer at a given price.
Supply can change due to numerous factors, including changes in production costs, availability of resources, and demand from customers. In contrast, quantity supplied is determined by the specific price of a product or service. For example, if the price of a product increases, producers will likely be more willing to increase the quantity supplied.
In short, the difference between supply and quantity supplied can be summed up as follows: Supply is the amount of goods and services a producer is theoretically willing to offer at different prices, while the quantity supplied is the actual amount of goods and services producers are willing to offer at a given price.

Examples of supply and quantity supplied
A key difference between the supply and quantity supplied is the amount of goods that are available for purchase. Supply refers to all the goods and services that are available in a market at any given time, while quantity supplied refers to the exact amount of goods that a seller is willing to put out on the market.
To better understand this difference, let’s look at some examples.
If a store has 200 computers in stock, then the store’s supply of computers is 200. This means that there are a total of 200 computers available to be purchased at any given time.
If the store only decides to put 10 of those computers out on display at any given time, then the store’s quantity supplied is 10. This means that only 10 of the available 200 computers are actually available for sale at any given time.
Another example of this distinction can be seen in agriculture. A farmer may have a supply of 100 apples but decide to sell only 50 of them at any given time. In this case, the farmer’s supply is 100 apples but his quantity supplied is only 50 apples.
It’s important to note that the amount of supply and quantity supplied can change over time depending on factors such as demand, production costs, and price. As such, supply and quantity supplied must be monitored regularly to ensure that buyers and sellers can benefit from efficient transactions.
Factors that influence supply and Quantity Supplied
Several factors can affect both the supply and the quantity supplied of a good or service.
One of the most important factors is the price of the good or service. An increase in price leads to an increase in the quantity supplied, as producers will try to capitalize on higher profits by producing more goods or services.
On the other hand, a decrease in price leads to a decrease in the quantity supplied, as producers may not be able to make enough money to justify producing the same amount of goods or services.
In addition, the cost of production can also have an impact on supply and quantity supplied.
An increase in production costs leads to a decrease in the quantity supplied, as producers cannot afford to produce as much at higher prices. Similarly, a decrease in production costs can lead to an increase in the quantity supplied, as producers can produce more at a lower cost.
Finally, consumer demand is also a major factor that affects supply and quantity supplied. When consumer demand increases, producers are incentivized to increase production, leading to an increase in the quantity supplied. On the other hand, when consumer demand decreases, producers may reduce their production, leading to a decrease in the quantity supplied.
These are just a few of the many factors that influence supply and quantity supplied. By understanding how each of these factors affects supply and quantity supplied, businesses can better plan for their production needs and ensure they are meeting the demands of their customers.
