Income/Price Elasticity of Demand

This calculator can solve for any of the 5 aspects of the income/price elasticity of demand formula which is denoted below as:

Income elasticity of Demand = (Starting Income Amount * Change in Quantity Demanded) / (Starting Quantity Demanded * Change in Income Earned)

EXAMPLE:  You currently earn 8 dollars an hour.  At this salary, you consume 6 dozen eggs.  You get a raise.  You now make 12 dollars per hour.  At this salary, you consume 12 dozen eggs.  Calculate the income elasticity of demand.

First, Press income elasticity of demand and enter 6 for start quantity, 12 for end quantity, 8 for start income, and 12 for end income and press Calculate.  Your answer is 2.00.
