Activation rate
Activation metric. Do new users reach first value?
What is activation rate?
Activation rate is the share of new installs that reach the first meaningful step you define, usually a completed sign-up, within a set number of days.
Activation event: the single in-app event you treat as proof that a new user has started using the product.
Install cohort: all users who installed in the same day, week or month.
How to calculate Activation rate
Activation rate = Users who activated ÷ Installs × 100- Users who activated
- users from the install cohort who completed the activation event inside the window
- Installs
- installs in the cohort
Where definitions differ
| Variant | Formula | When to use it |
|---|---|---|
| Install-to-sign-up rate | Sign-ups ÷ Installs × 100 | The most common activation metric. |
| Custom activation | Users completing a first value event ÷ Installs × 100 | First lesson, first deposit, first video played, tutorial complete. |
| Windowed activation | Activated by day 0, 1 or 7 ÷ Installs × 100 | Fix the window; a 7-day rate is always at least the 1-day rate. |

What counts as activation?
Activation is the first action that shows a new user has got real value or committed, chosen by you: a sign-up, a first lesson, a first deposit. Pick one event per app, give it a time window and keep it fixed so the rate is comparable over time.
How Activation rate differs by vertical
| EdTech | Sign-up plus first lesson started is a stronger activation event than sign-up alone. |
|---|---|
| Fintech | Sign-up is the first gate; KYC complete is often the real activation point. |
| OTT and streaming | First video played is the usual activation event. |
| Gaming | Tutorial complete; sign-up is often skipped entirely. |
Common mistakes
- Changing the activation event and then comparing with old months.
- Counting returning users who reinstall as new activations.
- Measuring activation from sign-ups instead of installs, which hides store-to-app drop-off.
Questions
How do you calculate install-to-sign-up rate?
Divide the users who signed up by the installs in the same cohort and multiply by 100. 2.5k sign-ups from 10k installs is a 25% install-to-sign-up rate.
Why does activation matter more than installs?
Two campaigns with the same CPI can have very different activation rates, so the cost per real user can differ several times over. Activation turns install volume into users who actually started.
What window should I use for activation?
Use the window in which most of your activations happen, often day 0 or day 1 for sign-ups and up to day 7 for deeper events. Whatever you choose, keep it fixed.
Does the calculator send my numbers anywhere?
No. It runs entirely in your browser, and nothing you type is stored or sent anywhere.
Why do tools report different values for the same metric?
Because definitions differ: what counts as active, which attribution window applies, whether organic users are included and how days are cut by timezone. Align the definition before comparing numbers.
Which currency do the calculators use?
The calculators show US dollars, but every formula works in any currency: enter your own figures in the currency you report in and read the results in that currency.
