Definition in plain terms
Price elasticity of demand measures how much the quantity customers buy changes in response to a change in price. If a small price increase causes a large drop in demand, the product is price-elastic - demand is sensitive to price.
If a price increase causes little change in demand, it's price-inelastic - demand is relatively insensitive.
The distinction matters enormously for revenue: for inelastic products, raising the price increases total revenue because you lose little volume, while for elastic products, raising the price can reduce total revenue because the volume lost outweighs the higher price.
Elasticity depends on factors like how essential the product is, the availability of substitutes, and how much of a customer's budget it represents. Understanding a product's elasticity tells you which direction to move price to grow revenue.
Why it matters to growth leaders
Price elasticity is the concept that tells a growth leader whether a pricing change will help or hurt, making it central to any pricing decision.
The instinct that lowering prices boosts revenue, or that raising them hurts it, is only true for elastic demand - for inelastic products, the opposite holds, and raising price grows revenue with little volume loss.
A growth leader who understands elasticity tests and reasons about it rather than assuming: which products or segments have sensitive demand (where competitive pricing and promotions matter) versus insensitive demand (where there's room to raise prices).
It also informs discounting - deep discounts only pay off if demand is elastic enough that the extra volume more than compensates for the lower price.
Estimating elasticity, even roughly through price tests, turns pricing and promotion decisions from guesses into informed bets, and frequently reveals that a product has more pricing power than the team assumed.
a meaningful price increase causes only a small drop in volume, because the product is essential to customers, has few close substitutes, and represents a modest share of their budget.
Because demand is inelastic, raising the price increases total revenue: the small volume lost is far outweighed by the higher price on the customers who stay.
The growth leader also examines a price-elastic product line, where demand is sensitive and the same price increase would lose enough volume to reduce revenue - so there, competitive pricing and promotions matter more.
Understanding elasticity, the leader raises prices where demand is inelastic and there's untapped pricing power, holds or sharpens prices where demand is elastic, and treats discounting as worthwhile only where the extra volume more than compensates.
Reasoning about elasticity rather than assuming, the growth leader makes pricing moves that grow revenue - and discovers, as is common, that the product had more pricing power than the team believed.

Origin & history
Price elasticity of demand quantifies how demand responds to price; whether a product is elastic or inelastic determines the revenue effect of price changes, making it foundational to pricing and promotion strategy.

Common questions
- What is price elasticity of demand?
- A measure of how sensitive the quantity demanded is to a change in price — elastic demand falls sharply when price rises, while inelastic demand barely moves.
- Why does elasticity matter for pricing?
- It determines whether a price increase raises or lowers revenue: for inelastic products, raising price grows revenue with little volume loss; for elastic products, it can cut revenue as lost volume outweighs the higher price.
- What makes demand elastic or inelastic?
- Factors like how essential the product is, the availability of substitutes, and how much of a customer's budget it represents — essentials with few substitutes tend to be inelastic.
