什么是 Price Elasticity?
Price elasticity of demand measures how quantity demanded responds to price changes. Elastic demand (|elasticity| > 1) means quantity changes more than price. Inelastic demand (|elasticity| < 1) means quantity changes less than price. Understanding elasticity helps businesses optimize pricing strategies, predict revenue changes, and make informed decisions about price adjustments.
How to use
输入 the initial and final prices, along with initial and final quantities sold. 选择 the calculation method (Arc elasticity is recommended for larger changes, Point elasticity for small changes). The 计算器 displays elasticity value, classification (elastic/inelastic), and shows how revenue would respond to various price changes.
常见问题
What is Price Elasticity of Demand?
Price Elasticity of Demand (PED) measures how the quantity demanded of a good responds to a change in its price. It calculates the percentage change in quantity demanded divided by the percentage change in price.
How is Price Elasticity calculated?
The standard formula is: Price Elasticity = (% Change in Quantity Demanded) / (% Change in Price). If you are using the Midpoint Method, the formula uses the average of the initial and final prices and quantities to calculate the percentage changes.
Why is the result usually negative?
According to the law of demand, as the price of a good increases, the quantity demanded usually decreases. Because price and quantity move in opposite directions, the ratio is typically negative.
What is the difference between elastic and inelastic?
Demand is considered 'elastic' if the absolute value is greater than 1 (quantity changes significantly with price). It is 'inelastic' if the absolute value is less than 1 (quantity is relatively unresponsive to price changes).
What does 'Unit Elastic' mean?
Unit Elastic occurs when the Price Elasticity is exactly -1 (or 1 in absolute terms). This means the percentage change in quantity demanded is exactly equal to the percentage change in price.
Why use the Midpoint Method?
The Midpoint Method provides the same elasticity value regardless of whether you go from the lower price to the higher price or vice versa. It avoids the confusion of having a different result when calculating price increases versus decreases.
