Difference Between Supply and Demand (With Table)

There are many Economic factors on which any country is based off. They are the basic factors which help in regulating the market as well ad the export and import. Such two macro-economic factors are Supply and Demand that are often used by bankers, economists and are a discussion point. They are interrelated to each other yet very different from each other.

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 of 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 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 need and want 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 also will get decreased. Demand usually represents how much the buyer likes the product and their preferences.

Parameters of ComparisonSupplyDemand
DefinitionSupply refers to the number of products or services provided to the clients and customers who are willing to buy them in an open market.When the clients or customers want to receive or buy products or services in a given period of time in an open market.
Inter-relationship When the supply becomes surplus, the demand gets decreased.When the demand is high, the supply goes less.
RepresentsIt represents that how much are sellers are willing.It represents that how much the customers and buyers are willing for the products.
Effects of priceWhen the price increases, the supply also increases and is related positively to the price.When the price falls, the quantity of demand increases and is inversely related to price.
CurveIt is always represented as upward sloping.It is always represented as downward sloping.

What is Supply?

Supply is the amount and quantity of commodities and products to be given and sold to the buyers and customers at a specific period of time. Laws regarding the Supply of products states 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 generally remains an upward sloping curve. The supply increases when the demand is high and goes down with the decrease in demand which leads to a shortage. There are certain factors on which the supply is based on 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 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 which influences the demand such as how much incomes do the customers have, the buyer’s taste and preferences, price of other and related good in the market, the population of the area, the number of substitutes that can be used in place of the original, etc. It all deepens the bargaining power of the customer for the given product.

Main Differences Between Supply and Demand

  1. Supply is termed as making available the products or services to the user and customers for them to use, whereas Demand is termed as the need of the product or services by the customers to the sellers for them to use.
  2. Supply is positively related to price and increases as the price increases, whereas Demand is inversely related to price and the demand becomes lower when the price goes high.
  3. The supply curve is an upward slope, whereas Demand is represented as a downward slope.
  4. Supply represents the willingness of the sellers and firms to sell the products, whereas Demand expresses the willingness of the customers and buys for the products.
  5. Both supply and demand are inversely related, and when one goes high, the other one goes low.
  6. Supply is derived by the bargaining power of the one who supplies the product, whereas Demand is derived by the bargaining power of the buyer of the products.
  7. Supply is the representation of the stock availability of the product by the seller in the market, whereas Demand is the representation of the tastes and preferences of the customers and buyers for the products.

Conclusion

The difference mentioned above is clearly showing how both terms Supply and Demands are different yet interrelated to each other. Supply is somewhere related to a time factor. It is very important for the suppliers to react to the sudden change in demand and price that will help them to determine whether the changes in price are temporary or permanent. Demand, unlike supply, has no such time factor impact on their demand relationship.
