Calculation Formula

Implements the economic Midpoint (Arc) Elasticity formula: $E_d = \frac{(Q_2 - Q_1) / ((Q_1 + Q_2)/2)}{(P_2 - P_1) / ((P_1 + P_2)/2)}$. Classification: $|E_d| > 1$ Elastic, $|E_d| < 1$ Inelastic, $|E_d| = 1$ Unitary Elastic.

How to Use the Price Elasticity of Demand Calculator

  1. 1 Enter the Initial Price ($) and New Price ($).
  2. 2 Enter the Initial Quantity Sold and New Quantity Sold.
  3. 3 Review your Price Elasticity Coefficient ($E_d$) and economic classification (Elastic, Inelastic, Unitary).
  4. 4 Inspect the Total Revenue Impact analysis ($) showing whether price changes increased or decreased overall revenue.

Methodology & Algorithmic Standards

Implements the economic Midpoint (Arc) Elasticity formula: $E_d = \frac{(Q_2 - Q_1) / ((Q_1 + Q_2)/2)}{(P_2 - P_1) / ((P_1 + P_2)/2)}$. Classification: $|E_d| > 1$ Elastic, $|E_d| < 1$ Inelastic, $|E_d| = 1$ Unitary Elastic.

Frequently Asked Questions

What does an "Inelastic" demand coefficient mean? ▼

If $|E_d| < 1$, demand is inelastic: consumers are relatively insensitive to price changes. Raising prices will increase total revenue because the percentage decrease in sales volume is smaller than the percentage price increase.

Why use the Midpoint formula instead of standard percentage change? ▼

The midpoint formula yields the exact same elasticity coefficient regardless of whether price moves up or down between two price points, avoiding directional asymmetry.
