Cross-Price Elasticity of Demand

`"Cross-Price Elasticity of Demand" = ( CDA )/( CPB )`
`(CDA) % Delta " in the Quantity Demanded of the first product"`
`(CPB) % Delta " in the Price of the second product"`

The Cross-Price Elasticity of Demand calculator computes the ratio that indicates how the demand change in one product responds to the price change in another.  

INSTRUCTIONS Enter the following:

  • (CDA) Percent change in the demand of Product 1
  • (CPB) Percent change in the price of Product 2 

Cross-Price Elasticity of Demand (EXY): The calculator computes the Cross-Price Elasticity of Demand.  Note elasticity is rounded to the nearest 1/1000th

The Math / Science

The formula for Cross-Price Elasticity of Demand is:

    EXY = (%ΔQX) / (%ΔPY)
