Demand Elasticity Formula:
| From: | To: |
Elasticity of demand measures the responsiveness of quantity demanded to changes in price. It indicates how sensitive consumers are to price changes for a particular good or service.
The calculator uses the elasticity of demand formula:
Where:
Explanation: The formula calculates the ratio of the percentage change in quantity demanded to the percentage change in price, providing a measure of demand sensitivity.
Details: Understanding demand elasticity is crucial for pricing strategies, revenue optimization, market analysis, and economic forecasting. It helps businesses determine optimal price points and predict consumer behavior.
Tips: Enter the percentage change in quantity demanded and percentage change in price as decimal values (e.g., 10% as 10). The price change cannot be zero as division by zero is undefined.
Q1: What do different elasticity values mean?
A: |E_d| > 1 = elastic demand, |E_d| < 1 = inelastic demand, |E_d| = 1 = unit elastic, E_d = 0 = perfectly inelastic, E_d = ∞ = perfectly elastic.
Q2: How is percentage change calculated?
A: %Δ = [(New Value - Old Value) / Old Value] × 100%. Use the same formula for both quantity and price changes.
Q3: What factors affect demand elasticity?
A: Availability of substitutes, necessity vs luxury, time horizon, proportion of income spent, and brand loyalty.
Q4: Why is elasticity important for businesses?
A: It helps determine pricing strategies - if demand is elastic, lowering prices may increase revenue; if inelastic, raising prices may increase revenue.
Q5: What's the difference between elastic and inelastic demand?
A: Elastic demand means consumers are very responsive to price changes (luxury goods), while inelastic demand means consumers are less responsive (essential goods).
