Price elasticity of supply relates to the responsiveness to the quantity supplied of a product or service to a change in the price. This price elasticity of supply calculator was created to facilitate the simple calculation of PES. This calculator will show you both the formula for working out price elasticity of supply as well as each of the steps through the calculation. This calculator uses the midpoint method for calculating elasticity which is more accurate than using the simple percentage variances for quantity supplied and price. By using the midpoint method the elasticity result is the same for a price decrease or increase as the midpoint is literally between supply1 and supply2 as well as price1 and price2. Please note the results have been applied an absolute value (always positive) for ease of understanding.
