Cómo funciona

  1. 1

    Enter the initial and new quantities demanded.

  2. 2

    Enter the initial and new prices.

  3. 3

    The calculator computes the percentage change in quantity and price using the midpoint method.

  4. 4

    The elasticity is the ratio of these percentage changes.

((q2 - q1) / ((q1 + q2) / 2)) / ((p2 - p1) / ((p1 + p2) / 2))

Preguntas frecuentes

What does a negative elasticity mean?

It reflects the law of demand: as price rises, quantity demanded falls. The negative sign is often ignored in absolute value.

Why use the midpoint method?

It gives the same elasticity whether price rises or falls, avoiding the problem of different results depending on the direction of change.

How do I interpret the magnitude?

If |elasticity| > 1, demand is elastic (quantity responds strongly). If < 1, demand is inelastic. If = 1, it is unit elastic.

Midpoint Elasticity

E = ((Q2 - Q1) / ((Q1 + Q2)/2)) / ((P2 - P1) / ((P1 + P2)/2))

This formula calculates the percentage change in quantity relative to the percentage change in price, using averages to avoid direction bias.

Casos de uso reales

Dónde aparece este cálculo en la vida cotidiana.

Pricing Strategy

Determine whether a price increase will increase or decrease total revenue based on elasticity.

Example: If demand is elastic, a price cut increases revenue.

Market Analysis

Assess how sensitive consumers are to price changes for a product or service.

Example: Compare elasticity across different customer segments.

Tax Incidence

Understand how the burden of a tax is shared between buyers and sellers.

Example: More inelastic side bears more of the tax.

Consejos y errores comunes

Tips

  • Use the midpoint method for consistent results.
  • Elasticity is unit-free, so it can be compared across products.
  • For small changes, the point elasticity formula is a good approximation.
  • Remember that elasticity can vary along the demand curve.

Common Mistakes to Avoid

  • Using the initial values instead of averages for percentage changes.
  • Ignoring the negative sign and misinterpreting the magnitude.
  • Confusing elasticity with slope; slope is not unit-free.

Supuestos y limitaciones

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
