Using Cross price elasticity calculator
Compare the target product’s quantity change with another product’s price change using midpoint percentages.
Uses two different products. A positive or negative estimate is an association in these inputs, not proof of substitution, complementarity or causality. Fixed assumptions only: no taxes, fees, changing returns, guarantees or product eligibility. Amounts share one currency.
A worked example
Example inputs: other product initial price = 10, other product new price = 12, target product initial quantity = 100, target product new quantity = 120. Cross-price elasticity = 1.
Before you use the result
Uses two different products. A positive or negative estimate is an association in these inputs, not proof of substitution, complementarity or causality. Fixed assumptions only: no taxes, fees, changing returns, guarantees or product eligibility. Amounts share one currency.
Example results for other product initial price
These examples use Other product new price: 12; Target product initial quantity: 100; Target product new quantity: 120. They are reference calculations, not recommended settings.
