Price elasticity of demand is a measure of how sensitive customers are to changes in the price of a product. It can help you determine the optimal price for your products that maximizes your revenue and profit. In this article, you will learn what price elasticity of demand is, how to calculate it, and how to use it to set optimal prices for your products.
Price elasticity of demand (PED) is the ratio of the percentage change in the quantity demanded of a product to the percentage change in its price. It indicates how responsive customers are to price changes. A high PED means that customers are very sensitive to price changes and will buy more or less of a product depending on the price. A low PED means that customers are not very sensitive to price changes and will buy a similar amount of a product regardless of the price.
Price elasticity of demand is a measurement of the change in the demand for a product in relation to a change in its price. Elastic demand is when the change in demand is large when there is a change in price. Inelastic demand is when the change in demand is small when there is a change in price. For example if the price of the product increase by 5% this increase effect decease the sales by 10 % that is mean the price elasticity .This can be measured by the equation Price Elasticity of Demand = Percentage Change in Quantity Demanded ÷ Percentage Change in Price PED= 10%/5%=2% .
You can use price elasticity of demand to set optimal prices for your products by understanding how sensitive consumers are to price changes. If demand is elastic, lowering prices can increase revenue, while for inelastic demand, raising prices may lead to higher profits without significant loss in sales volume.
To calculate PED, you need to know the initial and final prices and quantities of a product. The formula for PED is: PED = (Q2 - Q1) / Q1 / (P2 - P1) / P1 where Q1 and P1 are the initial quantity and price, and Q2 and P2 are the final quantity and price. The PED can be positive or negative, depending on whether the product is a normal good or an inferior good. A normal good is a good that customers demand more of as their income increases, such as clothing or entertainment. An inferior good is a good that customers demand less of as their income increases, such as public transportation or generic brands. For normal goods, the PED is usually negative, meaning that as the price increases, the quantity demanded decreases, and vice versa. For inferior goods, the PED is usually positive, meaning that as the price increases, the quantity demanded increases, and vice versa.
The Price Elasticity of Demand (PED) can be classified into five categories which describe how customers respond to price changes and how this affects the total revenue and profit of a product. Perfectly elastic PED is equal to negative infinity, meaning customers will only buy a product at a certain price and not any other. With elastic PED less than negative one, customers are very sensitive to price changes with the percentage change in quantity demanded being greater than the percentage change in price. Unitary PED is equal to negative one, meaning customers are moderately sensitive to price changes with the percentage change in quantity demanded being equal to the percentage change in price. Inelastic PED is greater than negative one, meaning customers are not very sensitive to price changes and the percentage change in quantity demanded is less than the percentage change in price. Lastly, perfectly inelastic PED is equal to zero, meaning customers are completely insensitive to price changes and will buy the same amount of a product regardless of the price.
PED can be categorized according to the number calculated by dividing the percentage change in quantity demanded by the percentage change in price. 1-( Infinity) Perfectly elastic Changes in price result in demand declining to zero. 2- Elastic PED >1Changes in price yield a significant change in demand 3- Unitary PED=1 Changes in price yield equivalent (percentage) changes in demand 4- Inelastic PED<1Changes in price yield an insignificant change in demand. 5- Perfectly inelastic PED=0 Changes in price yield no change in demand.
In order to set optimal prices using PED, you need to estimate the PED of your product and compare it with your marginal cost. If the PED is elastic, you should lower your price until it is equal to the marginal cost or until the PED becomes unitary, which will increase your quantity demanded, total revenue, and profit. If the PED is inelastic, you should raise your price until it is equal to the marginal cost or until the PED becomes unitary, which will decrease your quantity demanded but increase your total revenue and profit. If the PED is unitary, you have already reached the optimal price and should not change it. However, if the PED is perfectly elastic or perfectly inelastic, you cannot change your price without losing all or some of your customers. In this case, you should focus on reducing costs or increasing value proposition to increase profit.

To use price elasticity of demand to set optimal prices for your products, first identify, through an economic analysis, the point at which demand gets static when prices are changed. This point will assist in setting an optimal price that the market would be willing to pay.
There are several methods to estimate PED, such as using historical data, conducting surveys, running experiments, or applying economic models. However, these methods have their limitations and challenges, such as data availability, accuracy, reliability, validity, and applicability. Therefore, you should use a combination of methods and test your assumptions and results regularly. You should also consider other factors that may affect the demand for your product, such as income, preferences, substitutes, complements, seasonality, and trends. You should monitor the changes in these factors and adjust your prices accordingly.
