How the Price Elasticity of Demand Calculator works
Elasticity = % change in quantity ÷ % change in price, using the midpoint method. Values above 1 (ignoring the sign) mean demand is elastic. Example: with Old price $10, New price $11, and Old quantity sold 1,000, the result is Price elasticity = -0.88; Demand type = Inelastic (not very sensitive); Revenue change = $120.
