How to calculate price elasticity of demand
Price elasticity of demand measures the responsiveness of the quantity demanded to a change in price. It helps us understand how sensitive consumers are to price changes and the impact of these changes on demand.
The formula for price elasticity of demand is:
Price elasticity of demand = (Percentage change in quantity demanded) / (Percentage change in price)
To calculate the price elasticity of demand, follow these steps:
-
Determine the initial price and quantity demanded: Note down the initial price of the product and the corresponding quantity demanded.
-
Determine the new price and quantity demanded: Identify the new price at which you want to calculate the elasticity, and the corresponding quantity demanded at that price.
-
Calculate the percentage change in quantity demanded: Subtract the initial quantity demanded from the new quantity demanded. Divide the result by the initial quantity demanded and multiply by 100 to get the percentage change.
Percentage change in quantity demanded = ((New quantity demanded - Initial quantity demanded) / Initial quantity demanded) * 100
-
Calculate the percentage change in price: Subtract the initial price from the new price. Divide the result by the initial price and multiply by 100 to get the percentage change.
Percentage change in price = ((New price - Initial price) / Initial price) * 100
-
Use the formula to calculate price elasticity of demand: Divide the percentage change in quantity demanded by the percentage change in price.
Price elasticity of demand = (Percentage change in quantity demanded) / (Percentage change in price)
-
Analyze the result: The result of the calculation will be a number, and its interpretation depends on its magnitude.
-
If the price elasticity of demand is greater than 1, it means that demand is elastic. A change in price will lead to a proportionally larger change in quantity demanded.
-
If the price elasticity of demand is less than 1, it means that demand is inelastic. A change in price will lead to a proportionally smaller change in quantity demanded.
-
If the price elasticity of demand is equal to 1, it means that demand is unit elastic. A change in price will lead to a proportionally equal change in quantity demanded.
-
If the price elasticity of demand is infinity (or undefined), it means that demand is perfectly elastic. Any change in price will result in an infinite change in quantity demanded.
-
By calculating price elasticity of demand, businesses can make informed decisions about pricing strategies and understand how changes in price will impact demand for their products or services.
