Formula
Sum of (Activation timestamp - Signup timestamp) / Number of activated users
How to measure
Timestamp signup and the activation event for each user, then average the elapsed time across all users who activated in the period.
Why track it
This metric tracks whether onboarding changes are actually speeding up the path to activation over time.
Example
A team cuts signup-to-activation time from 4 days to 6 hours after simplifying the initial setup flow.
