When a firm changes prices‚ the effect on profits is more important than the effect on revenue. There is a simple formula to calculate the critical Price Elasticity of demand which is just sufficient to maintain the contribution to overheads and profits. This will be greater than that required to maintain revenue. A common issue in business and in business studies is whether a firm should change the prices at which products are offered. The calculations begin with estimates of the reaction of

Price elasticity of demand (PED) is a measure of how much the quantity demanded changes when there is a change in the price of the product. It can be calculated using the formula: PED= Percentage change in Qd of the product/ Percentage change in price of the product. When determining the price elasticity of demand‚ there are many possible outcomes which range from zero to infinity. If the PED value is between zero and one‚ then elasticity is said to be “Inelastic”‚ meaning there would be less

1. In order for Apple to calculate the estimated price elasticity of demand between the market prices of $2.99 versus $1.99‚ Apple must first estimate the percentage change in quantity demanded. Once the company can determine what effect each price will have on the quantity demanded‚ they can apply price elasticity of demand formula which is calculated by dividing the percent change in quantity demanded by the percent change in price. With the price information given‚ the percent change in price
