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 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.
