Definition

Activation rate measures what % of new users reach a meaningful 'aha' moment after signup (an early predictor of retention).

Formula

Activation rate = activated users / new signups

Example

If 1,200 of 5,000 signups reached activation, activation rate = 1,200 / 5,000 = 24%.

Common mistakes

  • Using vanity actions as activation (not linked to retention).
  • Comparing activation across products without aligning definitions.

Why this matters

This term matters because small changes compound in SaaS metrics. Use consistent definitions by cohort and segment so you can diagnose retention, payback, and growth quality.

Practical checklist

  • Write a 1-line definition for "Activation Rate" that your team will use consistently.
  • Keep the time window consistent (weekly/monthly/quarterly) when comparing trends.
  • Segment results (channel/plan/cohort) before drawing big conclusions from blended averages.
  • Use a calculator that references this term (e.g., Activation Rate Calculator) to sanity-check assumptions.
  • Read the related guide (e.g., Activation rate: definition, formula, and how to improve activation) for context and common pitfalls.
