PRICE ELASTICITY
Definition
Price elasticity measures how sensitive demand for a product is to a change in its price. Technically, it is calculated as the percentage change in the quantity sold divided by the percentage change in price.
A product is said to be "elastic" if a small change in price leads to a large change in quantity.
Why It's Important to Know
- Optimizing pricing decisions: Understanding price elasticity allows you to anticipate the impact of a price increase or decrease on revenue and margin.
- Managing promotions: Products with high price elasticity generate higher sales volumes during promotions, which can offset the decline in unit margins.
- Tailor the strategy by category: certain departments (fresh produce, apparel) have very different price elasticities, which require distinct pricing approaches.
Example
A clothing retailer lowers the price of a pair of jeans from €50 to €45 (-10%). Sales increase from 100 to 130 units per week (+30%). The price elasticity is -3 (change in demand / change in price = 30% / -10%).
This product is highly elastic: a price decrease leads to a sharp increase in sales volume. Conversely, a staple good (such as milk or bread) will have an elasticity close to 0, because consumers buy the same quantity regardless of the price.
How do you measure it?
Formula: Elasticity = (% change in quantity) / (% change in price)
Mistakes to Avoid
- Confusing elasticity with correlation: a decline in sales is not always due to price. Elasticity isolates the price effect by controlling for other variables.
- Use a single elasticity setting for all channels: elasticity can vary significantly between physical stores and online, or depending on geographic regions.
- Ignoring cross-price elasticity: Lowering the price of one product can affect sales of a competing or complementary product in the same product line.

Key takeaway:AI-powered pricing overcomes Excel's limitations by incorporating complex variables such as inventory and competition to model price elasticity accurately.
This robust approach safeguards margins and volumes while remaining transparent to managers. Key point: an elasticity exceeding 3.5 often indicates a data anomaly rather than actual customer behavior.
Key takeaway: Price elasticity measures how sensitive customers are to price changes, helping to optimize profitability. Identifying inelastic products allows you to adjust margins without sacrificing sales volume, while protecting key items helps maintain your price image.
A score above 1 indicates highly elastic demand, where any price increase is likely to cause sales to plummet.
To measure price elasticity, it is necessary to analyze how sales respond to price changes. This key indicator makes it possible to optimize profitability without sacrificing volume. It also helps identify opportunities to increase margins on inelastic products and protect price perception for price-sensitive items. A score of -1.5 thus indicates a high degree of demand responsiveness.
