Cross Elasticity of Demand Calculator
Enter quantity and price changes for two goods to calculate cross-price elasticity and determine if they are substitutes, complements, or independent.
Input Values
Good A — Quantity Demanded
Good B — Price
Formula Used
Cross-Price Elasticity of Demand
XED = % ΔQtyA / % ΔPriceB
% ΔQtyA = (New Qty − Old Qty) / Old Qty × 100
% ΔPriceB = (New Price − Old Price) / Old Price × 100
Enter values on the left and click Calculate XED to see results.
Cross-Price Elasticity (XED)
0.00
% Change in Qty A
—
Quantity demanded of Good A
% Change in Price B
—
Price of Good B
Interpretation
Classification Guide
Substitutes
(XED > 0)
Independent
(XED ≈ 0)
Complements
(XED < 0)
Summary
Enter quantity and price changes for two goods to calculate cross-price elasticity and determine if they are substitutes, complements, or independent.
How it works
- Enter the original and new quantity demanded for Good A.
- Enter the original and new price for Good B.
- The calculator computes the percentage change in quantity of A and the percentage change in price of B.
- XED is calculated as (% change in Qty A) divided by (% change in Price B).
- The result is classified as substitutes (XED > 0), complements (XED < 0), or independent (XED ≈ 0).
Use cases
- Analyze competitor pricing impact on your product demand.
- Determine market strategy for substitute or complementary product lines.
- Support economics coursework and exam preparation.
- Inform bundling or cross-selling decisions for related products.
- Assess how fuel price changes affect vehicle sales.
- Evaluate how streaming service price hikes affect DVD rental demand.
- Study market relationships for regulatory or antitrust analysis.
