Supply vs Demand: Difference and Comparison

There are many Economic factors on which any country is based. They are the basic factors that help in regulating the market as well as the exports and imports.

Such two macro-economic factors are Supply and Demand; bankers use economists and are a discussion point. They are interrelated to each other yet very different from each other.

Key Takeaways

  1. Supply refers to the amount of a product or service available in the market, while demand refers to the desire or need for that product or service.
  2. When the supply of a product is high and the demand is low, the price decreases, while when the supply is low, and demand is high, the price increases.
  3. The equilibrium point is where supply and demand are equal, and the market balances.

Supply vs Demand

The difference between supply and demand is that supply refers to the amount of the products required by the customers, and Demand refers to the need for the products which the suppliers are expected to supply. Supply and Demand are inversely related, and when one goes up, the other goes down.

Supply vs Demand

Supply is supplying the products and commodities for the customers to use on their demand. They are increased when the price increases, and usually, when the demand increases, the supplies go down.

This shows how much suppliers can give and make available the products to the customers and their willingness about the product.

Demand is the needs and wants of the customers and buyers for products at a specific period. The more the customers like the products, the more the demand will be.

If the price increases, then the demand will also decrease. Demand represents how much the buyer likes the product and their preferences.

Laws regarding the Supply of products state that the higher the price of the goodwill is, the higher the quantity of the products to be supplied. The supply is positively proportional to the price of the goods.

When talking about the supply curve, there remains an upward-sloping curve. The supply increases when the demand is high and goes down with the decrease in demand, leading to a shortage.

There are certain factors on which the supply is based, such as the price of the commodities or services, the number of suppliers in the market, any changes made in the technology, status of nature, price increment in the future, etc.

Usually, the bargaining power of the suppliers in the market drives the supply of the products. Supply not only represents the willingness of the suppliers but also tells about how much the products are able to be supplied for the given period of time.


What is Demand?

Following the opposite from that of the supply, Demand is the willingness of the customers to buy any product and service that they want.

The laws about Demand say that the higher the price of the products, the lower will be the demand for that product and good. They are inversely and negatively related to the price as less demand will be there.

If the supply of the products is the same and demand increases, there will be shortages and vice versa. The sloping curve is always downward for demands.

There are also some factors that influence the demand, such as how much income the customers have, the buyer’s taste and preferences, the price of other and related goods in the market, the population of the area, the number of substitutes that can be used in place of the original, etc.
