Income Elasticity Of Demand Calculator

Estimate income elasticity of demand from percentage changes in income and quantity demanded.

How the income elasticity of demand calculator works

Simple percentage method: elasticity = percentage change in quantity demanded ÷ percentage change in income. Results can differ from midpoint-method elasticity, especially for large changes.

Example and useful facts

Example: Estimate income elasticity of demand from percentage changes in income and quantity demanded. Enter the sample values above, then change one input at a time to see how the result changes.

Formula and assumptions: Simple percentage method: elasticity = percentage change in quantity demanded ÷ percentage change in income. Results can differ from midpoint-method elasticity, especially for large changes.

Did you know? Positive income elasticity often indicates a normal good; negative elasticity often indicates an inferior good, holding other factors constant.
