What to enter

|---|---|
| Activated cohort members (users) | Enter a whole count in users; keep the reporting population consistent. |
| Eligible signups (users) | Enter a whole count in users; keep the reporting population consistent. |
Understanding your result
Use the ratio to locate onboarding friction and compare like-for-like cohorts. Activation must be tested against later value rather than assumed to cause retention.
Common mistakes
- Counting repeated activation events inflates a unique-user numerator.
- Unequal observation windows bias cohort comparisons.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
Choose a consistent measurement basis
Document the activation event and observation window. Allow each signup the same follow-up time; incomplete recent cohorts can depress the measured rate.
A second independently worked case
Zero activations in an eligible 100-user cohort give 0%. Inputs: Activated cohort members: 0 users; Eligible signups: 100 users. Results: Activation rate: 0 %; Not activated within window: 100 users.
Precision and output units
Displayed results: Activation rate in %, rounded to 2 decimal places; Not activated within window in users, rounded to 0 decimal places. Display rounding does not establish the precision of the original measurements or estimates. A small positive rate can round to 0.00%; inspect the underlying counts before treating displayed zero as an absence of events.

How it works
Divide eligible signup-cohort members who completed the defined activation event by all eligible members. Subtract activated members to count those who did not qualify within the observation window.
Worked example
350 ÷ 1,000 × 100 = 35%; 650 did not activate within the chosen window. Enter activated cohort members 350 users, eligible signups 1000 users. The independently worked result is activation rate 35 %; not activated within window 650 users. Compare this example with your reporting definitions before substituting your own figures.
FAQ
Does one user performing the event ten times count as ten activations?
Not in this unique-cohort-member metric. Count that eligible user once when the event condition is met within the observation window.
How should very recent signup cohorts be treated?
Give members equal follow-up time or report immature cohorts separately. Otherwise users who have had less time to activate are compared with users who had a full observation window.
