What changes

Longer 14-day trials are often cited for an 8–20% relative lift in trial-to-paid versus 7-day trials, depending on time-to-value.

When this tends to work

  • Conditions similar to: B2B and prosumer SaaS, self-serve signup, 2022–2025
  • You can measure Trial-to-paid conversion rate reliably
  • The intervention is implemented consistently, not half-measured

When to be careful

  • Your audience or product differs materially from the cited context
  • Compliance costs or second-order effects outweigh the lift
  • Evidence label is estimate—treat wide ranges as planning bands, not promises

Practical takeaway

Use the cited range for prioritization and test design. Verify against your own data before scaling.
