What is Price Elasticity of Demand (PED)? Let's say you own a business that sells a product. You decide to increase the price of the product to see how it affects sales. Whether the quantity demanded for your product increases or decreases in response to a change in price is known as the price elasticity of demand (PED). The proper definition of Price Elasticity of Demand (PED) is:
Price Elasticity of Demand (PED) measures the responsiveness of the quantity demanded of a product to a change in its price.
Price Elasticity of Demand (PED) is a critical concept in economics and business. It helps businesses understand how changes in price can impact demand for their products. By calculating the PED for a product, businesses can make informed decisions about pricing strategies, revenue management, and market positioning.
The Price Elasticity of Demand formula is used to calculate the PED value based on the percentage change in quantity demanded and the percentage change in price. The PED value can help businesses determine whether demand for their product is elastic, inelastic, unitary elastic, perfectly elastic, or perfectly inelastic.

If the calculated PED value is greater than 1, it indicates that demand is elastic and sensitive to price changes i.e., a small change in price leads to a larger change in quantity demanded. If the PED value is less than 1, it indicates that demand is inelastic and less sensitive to price changes i.e., a change in price leads to a smaller change in quantity demanded. If the PED value is equal to 1, it indicates that demand is unitary elastic and the percentage change in quantity demanded equals the percentage change in price.

The midpoint formula is used to calculate the Price Elasticity of Demand (PED) by taking the average of the initial and final price and quantity values. This method provides a more accurate measure of elasticity by accounting for changes in both price and quantity. The Price Elasticity of Demand formula using the midpoint formula is:
Price Elasticity of Demand (PED) = [(Q₁ - Q₀) / ((Q₀ + Q₁) / 2)] / [(P₁ - P₀) / ((P₀ + P₁) / 2)]
In most of the cases, the PED value will be negative. This is because the law of demand states that as the price of any product increases, the quantity demanded for the product will decrease. However, the absolute value of PED is taken to determine the elasticity of demand.
When a product's demand is perfectly elastic, even the smallest price change causes demand to drop to zero. This typically occurs in markets with identical products where consumers can easily switch between alternatives. For example, generic medications show this behavior - if two identical drugs are available, consumers will always choose the cheaper option. Similarly, commodity products like grain see buyers immediately switching to cheaper alternatives when prices increase. In online retail, where price comparison is easy, even a slight price increase can cause customers to move to competitors.
Products with elastic demand see larger changes in quantity demanded compared to price changes. Consider luxury cars - a 10% price increase might trigger a 20% decrease in sales as buyers can postpone purchases or choose cheaper alternatives. Restaurant meals also show elastic demand since people can easily switch to home cooking when prices rise. Entertainment services like cinema tickets or streaming subscriptions typically show elastic demand due to the availability of numerous alternatives.
In unit elastic demand, the percentage change in quantity demanded exactly matches the price change. Mid-range electronics often exhibit this behavior - a 15% price increase leads to a proportional 15% decrease in demand. This also applies to certain clothing items and household appliances, where consumers carefully balance necessity with price sensitivity.
Products with inelastic demand see smaller changes in quantity demanded relative to price changes. Gasoline is a classic example - even a 20% price increase might only reduce consumption by 5% as people still need to commute. Basic food items and cigarettes also show inelastic demand due to their nature as necessities or addictive products.
With perfectly inelastic demand, quantity demanded remains constant regardless of price changes. Life-saving medications like insulin show this pattern - diabetics must purchase their prescribed amount regardless of price. Water in areas with limited supply and essential items like salt also demonstrate perfectly inelastic demand due to their fundamental necessity.
Using a price elasticity calculator or price elasticity of demand calculator helps businesses understand these patterns. Whether you're using the midpoint method calculator or an online price elasticity calculator, understanding your product's elasticity is crucial for pricing decisions and revenue optimization.
| Type of Elasticity | PED Value | Real-World Example | Price-Demand Relationship |
|---|---|---|---|
| Perfectly Elastic | ∞ | Generic medications with identical alternatives | Any price increase results in zero demand |
| Elastic | > 1 | Luxury cars, entertainment, designer clothing | % change in quantity > % change in price |
| Unit Elastic | = 1 | Mid-range electronics, restaurant meals | % change in quantity = % change in price |
| Inelastic | < 1 | Gasoline, basic food items, utilities | % change in quantity < % change in price |
| Perfectly Inelastic | 0 | Life-saving medications, insulin | No change in quantity regardless of price |
Let's consider a local coffee shop that recently increased the price of their lattes. The coffee shop owner wants to analyze the impact of the price increase on their weekly sales volume. Here are the details of the case study:
A local coffee shop wants to analyze the impact of their recent latte price increase:
Change in Quantity = [(Q₁ - Q₀) / ((Q₀ + Q₁) / 2)] × 100
= [(800 - 1000) / ((1000 + 800) / 2)] × 100
= [-200 / 900] × 100
= -22.22% (Quantity Decreased)
Change in Price = [(P₁ - P₀) / ((P₀ + P₁) / 2)] × 100
= [($4.50 - $4.00) / (($4.00 + $4.50) / 2)] × 100
= [$0.50 / $4.25] × 100
= +11.76% (Price Increased)
PED = |% Change in Quantity ÷ % Change in Price|
= |-22.22% ÷ 11.76%|
= 1.89
PED = 1.89 indicates the demand is elastic. For every 1% increase in price, quantity demanded decreases by 1.89%. This suggests customers are sensitive to price changes, and the coffee shop should carefully consider price increases as they significantly impact sales volume.
• Initial Revenue: 1000 × $4.00 = $4,000 • New Revenue: 800 × $4.50 = $3,600 • Revenue decreased by $400 (10%) due to elastic demand
In this way using our Price Elasticity of Demand Calculator, the coffee shop owner can determine that the PED value is 1.89. This indicates that the demand for lattes is elastic. For every 1% increase in price, the quantity demanded decreases by 1.89%. This suggests that customers are sensitive to price changes, and the coffee shop should carefully consider price increases as they significantly impact sales volume.

Q1. What is Price Elasticity of Demand (PED)?
•
Price Elasticity of Demand measures how responsive quantity demanded is to a change in price. Our price elasticity calculator helps determine if your product's demand is elastic (sensitive to price changes) or inelastic (less sensitive to price changes).
Q2. How do you calculate Price Elasticity of Demand?
•
Using our price elasticity of demand calculator, you can calculate PED using the midpoint formula: PED = [(Q₁ - Q₀) / ((Q₁ + Q₀)/2)] ÷ [(P₁ - P₀) / ((P₁ + P₀)/2)]. Simply input your initial and final prices and quantities.
Q3. What does a PED value greater than 1 mean?
•
A PED value greater than 1 indicates elastic demand - meaning customers are sensitive to price changes. For example, a 10% price increase might lead to a 20% decrease in demand. Luxury items typically show elastic demand.
Q4. What's the difference between elastic and inelastic demand?
•
Elastic demand (PED > 1) means quantity demanded changes more than proportionally to price changes. Inelastic demand (PED < 1) means quantity demanded changes less than proportionally to price changes. Use our elasticity calculator to determine your product's category.
Q5. Why use the midpoint method calculator?
•
The midpoint method calculator provides more accurate results because it uses average values of price and quantity, eliminating the issue of different results when calculating price increases versus decreases.
