When this calculator helps

  • Prioritizing onboarding investments by expected revenue lift.
  • Setting a target for an A/B test on trial-onboarding flow.
  • Building the business case for a customer success hire.

When to look elsewhere

  • Very low signup volume (<50/mo), variance swamps the signal.
  • Tools with no free trial (enterprise sales cycles).

Frequently asked questions

What's a good free-trial conversion rate?

Self-serve B2B SaaS averages 6-10%. PLG tools that gate value behind trial activation see 12-18%. Below 4% suggests either a wrong-fit audience or weak activation onboarding.

How big a lift is realistic?

Best-in-class onboarding overhauls deliver 1-3 percentage points. Email sequence tweaks deliver 0.3-0.8 points. Anything beyond 5 points usually means the prior funnel was deeply broken.
