# What Is Price Elasticity?

> Price elasticity measures how sensitive customer demand is to price changes—elastic demand drops sharply when prices rise; inelastic demand stays relatively stable.

**Price elasticity** quantifies the relationship between price and demand—critical for startups deciding whether price hikes grow revenue or destroy volume.

### How it works

Elasticity is often expressed as percentage change in quantity divided by percentage change in price. SaaS with high switching costs and mission-critical workflows tends toward inelastic demand; commodity tools with free alternatives skew elastic. Founders test elasticity through cohort price experiments, geographic splits, or packaging changes—not desk research alone.

Investors probe elasticity in diligence: NRR after price increases, churn spikes post-renewal, and win rates when competitors undercut. [Pricing power](/glossary/pricing-power) correlates with low elasticity and strong value perception.

### Why it matters

- **Founders:** Misjudging elasticity burns channels when aggressive list price increases meet silent churn at renewal.
- **Investors:** Growth at any price fails if elasticity is high—LTV models must reflect realistic retention after pricing moves.

### Common mistake

Using enterprise list price increases as proof of pricing power while SMB churn rises unmonitored in a separate segment.

## FAQ

### What is price elasticity in simple terms?

It answers: if we raise price 10%, how much does volume fall? Low elasticity means customers stay; high elasticity means they leave for cheaper alternatives.

### Why does price elasticity matter?

Investors assess whether startups can raise prices to improve margins or must compete on cost. Elasticity shapes LTV, churn, and expansion revenue assumptions.
