Price Elasticity Of Demand Calculator – Free Tool

This tool calculates the price elasticity of demand to help you understand how changes in price affect the quantity demanded.

How to Use this Price Elasticity of Demand Calculator

To use the calculator, please follow these steps:

  1. Enter the Initial Price of the product in the first field.
  2. Enter the New Price of the product in the second field.
  3. Enter the Initial Quantity demanded at the initial price in the third field.
  4. Enter the New Quantity demanded at the new price in the fourth field.
  5. Click the “Calculate” button to get the Price Elasticity of Demand.

How It Calculates the Results

The Price Elasticity of Demand (PED) measures the responsiveness of the quantity demanded of a good to a change in its price. It is calculated using the formula:

PED = (percentage change in quantity demanded) / (percentage change in price)


  • Percentage Change in Quantity Demanded = ((New Quantity – Initial Quantity) / Initial Quantity) * 100
  • Percentage Change in Price = ((New Price – Initial Price) / Initial Price) * 100

The resulting value indicates the elasticity. Values greater than 1 indicate elastic demand, values less than 1 indicate inelastic demand, and a value of 1 indicates unitary elasticity.


While this calculator provides a quick way to estimate the price elasticity of demand, it’s important to recognize its limitations:

  • The calculator assumes ceteris paribus—other factors affecting demand (like income, tastes, and the price of substitutes) remain constant.
  • The measurement is based on the point-to-point method and may not reflect minute incremental changes.
  • The accuracy depends on the quality of the input data.

Use Cases for This Calculator

Calculate the Price Elasticity of Demand

Enter the initial price, final price, initial quantity, and final quantity to determine the price elasticity of demand. The calculator will provide you with insights on how changes in price affect the quantity demanded.

Assess Elastic or Inelastic Demand

Upon entering the relevant data, the calculator will categorize the demand as elastic, inelastic, or unitary based on the calculated price elasticity value. This helps you understand consumer behavior and adjust pricing strategies accordingly.

Optimize Pricing Strategies

By analyzing the price elasticity of demand, you can tailor your pricing strategies to maximize revenue. Identify price points where demand is most responsive to changes, allowing you to make informed decisions to increase sales and profits.
