Open calculatorCross-Price Elasticity Calculator is an educational economics tool for exploring a standard quantitative relationship.
Enter the requested values using the stated definitions. The calculator validates the numerical domain and applies XED = midpoint %ΔQx / midpoint %ΔPy.
Variables: Qx₁ = Old quantity of good X; Qx₂ = New quantity of good X; Py₁ = Old price of good Y; Py₂ = New price of good Y.
Example: Qx: 100 → 90 and Py: 20 → 25 gives XED ≈ -0.4737.
It is intended for study, classroom exercises and quick exploration of the stated economic relationship.
No. Real economic outcomes depend on assumptions, institutions, expectations, market structure, policy settings, measurement choices and other factors beyond a simplified formula.
