In this method, the elasticity of demand is calculated as the percentage change in quantity demanded divided by the percentage change in price. The formula for calculating the elasticity of demand is given below: Interpreting Elasticity of Demand using Percentage Elasticity of Demand  Case Description Degree of elasticity Numerically, E d 1. If the calculated value is more than 1   More than Unitary Elastic or Elastic Demand   E d >1 2. If the calculated value is equal to 1 Unitary Elastic Demand   E d =1 3. If
