Open calculatorPrice Elasticity of Demand 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 PED = midpoint %ΔQd / midpoint %ΔP.
Variables: Q₁ = Old quantity demanded; Q₂ = New quantity demanded; P₁ = Old price; P₂ = New price.
Example: Q: 100 → 120 and P: 10 → 9 gives PED ≈ -1.7273 and |PED| ≈ 1.7273.
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.
