The Coefficient of Elasticity is an important economic concept used to measure how demand or supply reacts to changes in price. It is a fundamental principle in microeconomics, helping businesses and economists understand market behavior.
Formula
The Coefficient of Elasticity is given by:
E = P / Q
Where:
- E = Coefficient of Elasticity
- P = Price change
- Q = Quantity change
How to Use
- Enter the price change value.
- Enter the quantity change value.

- The calculator will display the Coefficient of Elasticity.
Example
Suppose the price increases by $10, and the quantity demanded decreases by 20 units.
Using the formula:
E = 10 / 20 = 0.5
This means that the demand is relatively inelastic.
FAQs
1. What does the Coefficient of Elasticity indicate?
It measures how much quantity demanded or supplied responds to price changes.
2. What does an elasticity greater than 1 mean?
It means the demand or supply is elastic, meaning it is sensitive to price changes.
3. What does an elasticity of 0 mean?
It means the demand or supply is perfectly inelastic, meaning price changes have no effect on quantity.
4. Why is elasticity important in economics?
It helps businesses set prices and governments implement taxation policies effectively.
5. What is price elasticity of demand?
It measures how the quantity demanded of a good changes in response to price changes.
6. Can elasticity be negative?
Yes, in the case of demand elasticity, where an increase in price leads to a decrease in demand.
7. How does elasticity affect revenue?
If demand is elastic, increasing prices can decrease total revenue, and vice versa.
8. What factors influence elasticity?
Availability of substitutes, necessity of the product, and proportion of income spent on the good.
9. How is elasticity different for luxury and necessity goods?
Luxury goods tend to have higher elasticity, while necessity goods have lower elasticity.
10. What is unitary elasticity?
When E = 1, meaning percentage changes in price and quantity are equal.
11. How does time affect elasticity?
Over time, elasticity tends to increase as consumers find alternatives.
12. Can supply elasticity be negative?
No, supply elasticity is always positive because higher prices usually encourage higher production.
13. How do governments use elasticity in taxation?
They tax inelastic goods (like gasoline) more, as demand remains stable despite price increases.
14. What is cross-price elasticity?
It measures how the demand for one good changes in response to the price change of another good.
15. What is income elasticity of demand?
It measures how demand for a good changes with consumer income.
16. Why do some goods have perfectly inelastic demand?
Essential goods like life-saving medicine have almost zero responsiveness to price changes.
17. What industries rely on elasticity calculations?
Retail, transportation, healthcare, and agriculture all use elasticity data for pricing strategies.
18. How does elasticity affect competition?
Highly elastic markets tend to have stronger competition since customers can switch products easily.
19. Can elasticity change over time?
Yes, as consumer preferences and market conditions shift, elasticity also changes.
20. What role does advertising play in elasticity?
Effective advertising can reduce elasticity by increasing brand loyalty.
Conclusion
The Coefficient of Elasticity Calculator is a valuable tool for businesses, economists, and policymakers. Understanding elasticity helps in making better pricing, marketing, and taxation decisions. Use this simple calculator to quickly determine elasticity for your economic analysis.
