Price Elasticity of Demand Calculator | PED Formula & Examples

Price Elasticity of Demand Calculator

Calculate how price changes affect demand using the midpoint method formula. Essential tool for economics students and pricing strategists.

Understanding PED

Price Elasticity of Demand measures how much the quantity demanded responds to price changes:

  • Elastic (|PED| > 1): Demand changes more than price (luxuries)
  • Inelastic (|PED| < 1): Demand changes less than price (necessities)
  • Unitary (|PED| = 1): Proportional changes

Practical Applications

PED is crucial for:

  • Pricing strategy optimization
  • Tax incidence analysis
  • Revenue forecasting
  • Market structure evaluation
  • Government policy making

Frequently Asked Questions

Why is PED usually negative?

PED is negative due to the law of demand – inverse relationship between price and quantity demanded. However, we often use absolute values when interpreting elasticity.

What factors affect price elasticity?

  • Availability of substitutes
  • Necessity vs luxury
  • Time horizon
  • Percentage of income
  • Brand loyalty

How does elasticity affect pricing decisions?

For elastic products (PED > 1), lowering prices may increase revenue. For inelastic products (PED < 1), price increases typically raise revenue as demand doesn't fall proportionally.

What is Price Elasticity of Demand (PED)?

Price Elasticity of Demand (PED) is a fundamental concept in economics that measures how much the quantity demanded of a good or service changes in response to a change in its price. This metric helps economists, businesses, and policymakers understand consumer behavior and market sensitivity. A high elasticity means consumers are highly responsive to price changes, while low elasticity means demand remains relatively stable regardless of price fluctuations.

Why Use a PED Calculator?

Accurately calculating price elasticity of demand can be time-consuming without the proper tools. Our free online PED calculator streamlines this process, allowing you to quickly determine how price changes impact demand. Whether you’re a student working on an economics assignment, a teacher demonstrating concepts in class, a business professional planning pricing strategies, or a researcher analyzing market trends, this tool is invaluable for making data-driven decisions.

  • Students: Visualize and understand elasticity for exams or projects
  • Teachers: Create hands-on learning experiences in the classroom
  • Businesses: Forecast how price adjustments affect sales volumes and revenues
  • Researchers: Analyze consumer responsiveness in various markets

The PED Formula Explained

The standard formula for price elasticity of demand is:

PED = (% Change in Quantity Demanded) ÷ (% Change in Price)
Or, using the midpoint method:
PED = [(Q2 – Q1) / ((Q2 + Q1)/2)] ÷ [(P2 – P1) / ((P2 + P1)/2)]

For example, suppose the quantity demanded decreases from 100 to 80 units when the price increases from $10 to $12. The percentage change in quantity is (-20/90), and the percentage change in price is (2/11). Using the formula, the PED would be -1.22, indicating elastic demand.
