How to Calculate, and Examples How to Calculate Elasticity of Demand There are three main types of price elasticity of demand elastic, unit elastic, and inelastic. Before delving deeper into this subject, it's best to have a good understanding of the law of supply and demand. To calculate the elasticity of demand or Price Elasticity of Demand PED, we use the following equation elasticity formula Where Change in Quantity Demanded Qd New Quantity Old Quantity Average Quantity Change in Price P New Price Old Price Average Price PED is always given as an absolute value, or positive value, because we are interested in its magnitude. Midpoint Method for Elasticity Some economic resources will instead calculate price elasticity using the following formula Change in Quantity Demanded Qd.
New Quantity Old Quantity Old Quantity Price Change P New Price Old Price Old Price Note that the denominator for both is the old quantity and price as opposed to the average price and quantity shown above. Using this formula is not ideal because the direction of changes in price or quantity can affect the figures calculated for price elasticity. Here is an example to illustrate this. The price Panama mobile number list of a pair of pants falls from $ to $ and the quantity demanded from to pairs of pants. The price elasticity of demand calculation for this is as follows elasticity formula However, if we reverse this example and the price of a pair of pants goes up, we get this calculation instead elasticity formula In this example, the numbers mentioned are the same, and the changes are exactly the same.
The only difference is the direction of change is different, leading to different demand elasticities. To solve this, the formula we used above uses the midpoint method for elasticity. The midpoint method uses the average quantity and price as the denominator for the percentage change formula as follows Change in Quantity Demanded Qd New Quantity Old Quantity Average Quantity Change in Price P New Price Old Price Average Price This solves a different elasticity problem, as we can see using the following calculations for the previous example elasticity formula Elasticity of demand According to the Investopedia page , elasticity of demand occurs when changes in price cause a disproportionately large change in the quantity demanded.
