Elastic vs. Inelastic? Elasticity = (Change in quantity/Average quantity) / (Change in price/Average price) Elasticity = ((Q1 - Q2) / (Q1 + Q2)/2 )) / ((P1 - P2)/( (P1 + P2)/2)) This formula will give you an approximation of the elasticity over a range, instead of a point- specific elasticity, but as the range gets larger, the result becomes less and less accurate, which is why many economists prefer to use the traditional measure of elasticity. It is a little difficult to visualize why elasticity is not constant on a straight-line graph without looking at a diagram. In , the slope of this hypothetical straight-line supply curve is constant (slope = 2), but the elasticity changes as you move along the graph. Let's assume that the price of this good is initially \$3, and then increases to \$5. In this case, the elasticity for the good can be calculated as follows: Elasticity = (% Change in Quantity) / (% Change in Price) Elasticity = [(2 - 1)/1] / [(5 - 3)/3] = 3/2
