Activation Rate

What is activation rate?

Activation rate measures the percentage of new users or subscribers who complete a defined set of onboarding actions that indicate they have started realizing value from the product. These actions vary by business but often include steps like completing a profile, consuming content for the first time, or engaging with a core feature.

Why activation rate matters

  • Early engagement predictor: Activation is the first major milestone after acquisition. A high activation rate shows that new users are quickly finding value, which increases the likelihood of long-term retention.
  • Onboarding effectiveness: Tracking this metric highlights how well onboarding flows are designed and where users may be dropping off.
  • Revenue impact: In subscription businesses, faster activation often translates into higher conversion from trials to paid plans and reduces the risk of early churn.

How to calculate activation rate

Activation rate = (Number of users who completed activation actions ÷ Total number of new users) × 100

The definition of “activation actions” should be tied to meaningful product usage rather than simple sign-ups or logins.

Inclusions and exclusions

  • Include: Completed actions that strongly correlate with long-term retention, such as finishing onboarding steps or using a key feature.
  • Exclude: Vanity actions like opening a welcome email or browsing without interaction, which do not demonstrate actual engagement.

Activation rate in subscription businesses

For subscription-driven companies, activation rate is a direct indicator of how quickly new subscribers connect with content or product value. Subsets helps improve activation by identifying friction points during onboarding and triggering tailored nudges such as personalized welcome flows or targeted prompts that guide users toward high-value actions. By optimizing activation, businesses can reduce early churn and set a foundation for sustainable retention.

The depth and breadth of the results analysis we can generate from Subsets has been invaluable. We are aiming to turn validated experiments into 'always on' and let Subsets select subscribers for targeting and trigger the campaigns.
