Price Elasticity Calculator

Use this calculator to estimate price elasticity of demand based on changes in price and quantity sold.

What this calculator does

The price elasticity calculator helps measure how sensitive demand is to price changes.

It is useful for:

• pricing strategy
• demand forecasting
• revenue modeling
• market analysis

Price Elasticity Formula

Elasticity = % Change in Quantity ÷ % Change in Price

Where:

• % Change in Quantity = change in quantity sold relative to old quantity
• % Change in Price = change in price relative to old price
• Elasticity = sensitivity of demand to price

Example calculation

If price increases by 10% and quantity sold falls by 20%:

• Elasticity = −20% ÷ 10%
• Elasticity = −2.0

What is price elasticity?

Price elasticity measures how much customer demand changes when price changes.

It helps show whether customers are highly price-sensitive or relatively insensitive.

Why price elasticity matters

Price elasticity helps businesses:

• set better prices
• forecast demand changes
• understand customer behavior
• improve revenue strategy

When to use this calculator

Use this calculator when you want to:

• evaluate a price increase
• model demand response
• compare pricing strategies
• understand market sensitivity

Common mistakes

Common mistakes include:

• using short-term data only
• comparing unrelated time periods
• ignoring outside factors like seasonality
• assuming elasticity is constant in all situations

Elastic vs inelastic demand

Elasticity results are often interpreted like this:

• Elastic demand means quantity changes strongly when price changes
• Inelastic demand means quantity changes only slightly
