Price Elasticity of Demand is a financial calculator that helps you calculate price elasticity of demand values from your input data. The formula used is: % Change in Qty = (New Qty − Old Qty) / Old Qty × 100\n% Change in Price = (New Price − Old Price) / Old Price × 100\nElasticity = |% Change Qty / % Change Price|. Enter monetary values in your local currency. Enter interest rates as plain numbers (e.g. enter 5 for 5 %).

Formula

% Change in Qty = (New Qty − Old Qty) / Old Qty × 100 % Change in Price = (New Price − Old Price) / Old Price × 100 Elasticity = |% Change Qty / % Change Price|

Example Calculation

Inputs
  • Original Price (PKR): 100 PKR
  • New Price (PKR): 120 PKR
  • Original Quantity Sold: 1000
  • New Quantity Sold: 800

Suppose you enter: Original Price (PKR) = 100, New Price (PKR) = 120, Original Quantity Sold = 1000, New Quantity Sold = 800. The calculator applies the formula (% Change in Qty = (New Qty − Old Qty) / Old Qty × 100\n% Change in Price = (New Price − Old Price) / Old Price × 100\nElasticity = |% Change Qty / % Change Price|) and shows all output values below. Change any input field to immediately see how the result changes.
