Price elasticity of demand refers to how much the sales of a product change when the price of that product changes. If the price of the product goes up and there is a great decrease in the sales of the product, we say that the demand for the product is elastic. If the price increases and there is not a great decrease in the sales of the product, we say that the demand for the product is relatively inelastic.

Here is an actual formula for finding elasticity more formally:

**PEoD = (% Change in Quantity Demanded)/(% Change in Price)**

If the price elasticity of demand is greater than 1 and less than infinity, we say that demand for that good is relatively elastic.

Price elasticity of demand is a measure of the extent to which demand for a product changes in response to the price of the product. It is calculated as the ration the ratio of percentage change in demand of the product in response to percentage change in price of the product. This measure of price elasticity of demand is also called the elasticity coefficient. Demand for a product is said to be price elastic when the elasticity coefficient is more than 1. For a product with price elastic demand, the percentage increase in price is more than the resulting percentage increase in price. For products like this any increase in price leads to reduction in the total revenue, while decrease in price leads to increase in total revenue.
