# Cross-Price Elasticity of Demand (E_{c}-PED) Calculation

(Step by step calculation)

# Cross-Price Elasticity of Demand (E_{c}) Calculator

E_{c} measures the demand of Product A when price of unrelated Product B is changed.

Step by step calculation

#### Cross-Price Elasticity of the Demand Formula 1

Cross-Price Elasticity of the Demand (E_{c}) = P1 / P2

Where,

E_{c} is Cross-Price Elasticity of the Demand

P1 is Percent Change in a Quantity of Good A

P2 is Percent Change in the Price of Good B

#### Cross-Price Elasticity of the Demand Formula 2

Where

E_{c} is the cross-price elasticity of the demand

P_{1}^{A} is the price of good A at time 1

P_{2}^{A} is the price of good A at time 2

Q_{1}^{B} is the quantity of good B at time 1

Q_{2}^{B} is the quantity of good B at time 2
