User Activation Rate
The percentage of new users who reach the event that predicts long-term retention.
Definition
User activation rate measures how many new users reach the specific product milestone - often called the "aha moment" - that correlates with long-term retention. It differs from onboarding completion rate in that it's defined by product value delivery, not tutorial completion. A user can complete all onboarding steps without activating if they never experience why the product matters. Activation rate is the single most predictive early-stage metric for retention and LTV.
Activation rate
Activation rate = users who reached activation event ÷ new users × 100
Example: 340 users reached "first_project_created" ÷ 1,000 new signups = 34% activation rate
→ In practice
"Our activation rate improved from 22% to 31% after we moved the data import step to after users saw their sample dashboard. That's the change that moved day-30 retention."
Common questions
How do I find my activation event?
Compare the first-week behavior of users who retained to day 30 vs users who churned. The event with the highest separation between the two cohorts is your activation event.
What is a useful activation-rate benchmark?
Use a stable internal baseline rather than a generic category range. Compare equivalent cohorts before and after a product change, and review the activation event definition, acquisition mix, and cohort size before attributing a movement to onboarding.
