Price Elasticity Formula
Price elasticity of demand can be regarded as a reflection of the customer or the consumer behavior because of a change in the price; on the other hand, the price elasticity of supply will measure the behavior of the producer. Both metrics are feeding into the other. Each of them is important while analyzing the marketplace economics, but at the end of the day, it is the price elasticity of demand that most of the entities or the companies will look to while establishing their sales strategy.
So, in order to calculate the price elasticity of demand following formula can be used.
Examples of Price Elasticity Formula (With Excel Template)
Let’s take an example to understand the calculation of the Price Elasticity formula in a better manner.
Price Elasticity Formula – Example #1
Let’s take a simple example to understand the same, suppose that the price of oranges will fall by 6%, say from $3.49 a bushel to $3.29 a bushel. Responding to that, the grocery shoppers will increase their oranges purchases by 15%. So what is its price elasticity?
Solution:
Price Elasticity of Demand for Oranges is calculated using the formula given below
Price Elasticity of Demand = % Change in the Quantity Demanded (ΔQ) / % Change in the Price (ΔP)
 Price Elasticity of Demand = 15% / 6%
 Price Elasticity of Demand = 2.6
and hence the elasticity will be 2.6 times, which shall be indicating that the oranges are quite elastic in relation to their demand.
Price Elasticity Formula – Example #2
Uber is one of the online platforms or an application to book rides at consumer’s choice and can ride anywhere from his initial place within the city. Uber has the concept of demand and price, which is where its price keeps on changing based on demand. Specifically, it has one contentious surge pricing feature that will use big troves of data on demand (i.e., by riders) and supply (i.e., of drivers) and regulate the prices in realtime and maintain the equilibrium from each and every moment. But, on the other hand, it also has the concept of surging the prices, which will ultimately dampen the demand.
According to data available, when one would go from nil surge to a 1.2x surge, one would notice a consistently precise dropin demand for about 27%. So, what is the price elasticity of uber surge pricing?
Solution:
As one can see, there is a drastic decline in demand when the price surges. So let’s calculate its price elasticity:
Price Elasticity of Demand is calculated using the formula given below
Price Elasticity of Demand = % Change in the Quantity Demanded (ΔQ) / % Change in the Price (ΔP)
Price Elasticity of Demand = 27% / 20%
Price Elasticity of Demand = 1.35
Therefore, from the above figure, we can conclude that Uber’s consumers are relatively priced elastic.
Price Elasticity Formula – Example #3
Taking another example of the mobile industry in India, say JIO, which launched its network at very cheap data rates where it provided a plan of 399 where consumers will get 1 GB of data daily until 80 days period and along with free calling and roaming whereas the market was offering 1 GB of data at a price of 249 for 1gb which only lasted a month. Reliance Jio had launched its mobile services commercially in early September 5 in 2016, and the service provider crossed the 130 million mark in 1 year of its operations and further at the end of March 2018, Jio (RIL) reported a subscriber base of 187 million which means, the company or the firm added close to 9 million users in the months of April, May, and June.
Solution:
% Change in the Price (ΔP) is calculated as:
% Change in the Quantity Demanded (ΔQ) is calculated as:
Price Elasticity of Demand is calculated using the formula given below
Price Elasticity of Demand = % Change in the Quantity Demanded (ΔQ) / % Change in the Price (ΔP)
Price Elasticity of Demand = 43.85% / 98%
Price Elasticity of Demand = 0.45
Explanation of the Price Elasticity formula
The law of demand states that as the price of the commodity or the product increases, the demand for that product or the commodity will eventually decrease, all conditions being equal. Consequently, as the price of a product or the commodity decreases, the demand for that product or the commodity as well increases. Therefore, the law of demand defines an inverse relationship between quantity factors of a product and the price, which is what the elasticity of the formula tries to say. The first part brings the change in quantity, and the second one is the change in price.
On the other hand, the law of supply states that an increase in the price of the product will cause an increase in the quantity supplied, all factors being constant. That is, the quantity that is being supplied will move in a similar direction as that of the price. Production units or the company will invest more in production and supply more products for sale at an increased price to generate a higher product. Therefore, the law of supply will define a direct relationship between the quantity and the price. That was the second formula that tries to say changes in quantity supplied by changes in price.
Relevance and Uses of Price Elasticity Formula
The product or the commodity would be considered highly elastic if it has a score higher than 1, meaning that the change greatly influences the demand in price.
A score between 0 to 1 can be considered as inelastic since the variation or the change in price has only a small impact on the product’s demand. A product or the commodity with an elasticity of 0 would be considered perfectly inelastic, as the change in price will have no impact on demand. Many bare necessities or household items have very lowprice elasticity of demand, as people need them regardless of price. E.g., Gasoline. Luxury items, such as airline tickets, bigscreen televisions, generally will have higher price elasticity because they are not essential in routine life.
