Cross-price elasticity measures how the demand for one product changes in response to a price change in another product.
How do you calculate cross-price elasticity?
Cross-price elasticity (XED) is calculated using the formula: XED = (% change in demand for product A) / (% change in price of product B).
What does a positive cross-price elasticity indicate?
A positive cross-price elasticity indicates that the products are substitutes, meaning when the price of one rises, the demand for the other increases.
What does a negative cross-price elasticity mean?
A negative cross-price elasticity means the products are complements, so when the price of one increases, the demand for both products decreases.
Why is cross-price elasticity important for businesses?
Cross-price elasticity helps businesses analyze market dynamics, optimize pricing strategies, and identify risks associated with pricing changes of competitive or complementary products.
Cross-Price Elasticity of Demand Formula, Meaning and Examples
Learn how to apply the cross-price elasticity formula, understand its types, and use it for competitive analysis, risk mitigation, and developing marketing strategies to boost revenue.

Cross-price elasticity measures how the demand for one product changes in response to a price change in another product. Companies use this calculation to gain insights into market behavior and customer preferences. The formula for cross-price elasticity (XED) is XED = (% change in demand for product A) / (% change in price of product B).
This formula helps businesses assess the link between demand and pricing. In this article, we’ll explain the cross-price elasticity formula, how to apply it, and how to interpret the results to make informed business decisions.
Cross-Price Elasticity of Demand Formula
The cross-price elasticity formula helps calculate the cross price elasticity of demand (XED) between two different products or services. It is expressed as:
Cross price elasticity (XED) = (% change in demand for product A) / (% change in price of product B),
where products A and B are distinct offerings.
This ratio shows how the demand for one product reacts to the price change of another. By using this percentage, businesses can evaluate whether adjusting prices or offering product substitutes would improve revenue.
To apply the formula, you need to know the percentage change in both the demand for product A and the price of product B. Use the following formulas to calculate these changes:
% change in demand = (new quantity - old quantity) / old quantity
% change in price = (new price - old price) / old price
The cross-price elasticity formula is a valuable tool that helps businesses understand market dynamics and develop strategies to boost revenue and stay competitive.
Types of Cross-Price Elasticity
There are three types of cross-price elasticity, and the results from the formula help you identify each one:
1. Substitutes
Substitute products or services meet similar customer needs but are different. For instance, if the demand for product A increases when the price of product B rises, it shows that customers are choosing product A over product B. This creates a substitution effect, and the cross price elasticity (XED) will be greater than zero, indicating that the products are substitutes.
2. Complements
Complements are the opposite of substitutes. In this case, if the demand for product X decreases due to a price increase in product Y, it suggests that customers find it more expensive to buy both products together. This consumer behavior shows that products X and Y are often used together. When products are complements, the cross price elasticity will be less than zero, meaning a negative value.
3. Unrelated Offerings
Unrelated products or services have no connection between price changes and demand. A price change in one product does not impact the demand for the other. When the cross-price elasticity result is zero, it indicates that the products are unrelated.
These distinctions help businesses understand the relationship between products and guide pricing strategies effectively.
Businesses and organizations gain valuable insights from analyzing a product’s cross-price elasticity, helping them understand both the market and consumer behavior. Here’s how companies can apply this analysis:
Competitive Analysis
: Cross price elasticity helps businesses identify competitors with similar products and market positions. By understanding how changes in pricing strategies for complementary or substitute products affect demand, companies can refine their marketing approaches to boost revenue.
Risk Identification and Mitigation
: Companies can use cross price elasticity to recognize potential risks to financial growth. By tracking how price changes in competing or complementary products influence demand, businesses can develop strategies to minimize risks and stabilize revenue in fluctuating markets.
Marketing Strategy Development
: When creating new marketing strategies, cross-price elasticity is essential. It allows companies to gauge how to expand market reach by determining the impact of competitive and complementary product pricing on consumer demand.
How to Use Cross-Price Elasticity of Demand Formula?
To apply the cross-price elasticity formula, follow these four simple steps:
1. Calculate the Percentage Change in Demand
First, find the percentage change in the quantity of demand for product A using the formula:
% change in demand = (new product quantity - old product quantity) / old product quantity
For example, if the new product quantity is 6,000 units and the old product quantity is 11,350 units, the formula would be:
% change in demand = (11,350 - 6,000) / 6,000 = 0.89 or 89%
This result shows an 89% increase in the demand for product A.
2. Calculate the Percentage Change in Price
Next, calculate the percentage change in the selling price of product B using this formula:
% change in price = (new selling price - old selling price) / old selling price
Assume product B’s new price is $50 and the old price was $37. Using the formula:
% change in price = ($50 - $37) / $37 = 0.35 or 35%
This indicates a 35% increase in the price of product B.
3. Divide the Percentages to Find Cross-Price Elasticity
Now, use the values from steps 1 and 2 in the cross-price elasticity formula:
Cross price elasticity (XED) = % change in demand of product A / % change in price of product B
For our example, this would be:
XED = 89% / 35% = 2.54
Since the result is greater than zero, this means products A and B are substitutes.
4. Interpret the Results
Finally, interpret your result. In this example, a cross price elasticity of 2.54 indicates that when the price of product B increases, the demand for product A rises. This suggests consumers are switching to product A because it’s now relatively cheaper, confirming that these products are substitutes fulfilling similar needs.
