How the calculation works
Retention rate = returning players ÷ starting cohort × 100
Example
If 320 of 1,000 new players return on day 1, day-1 retention is 32%.
Why this result matters
Retention shows whether a specific install cohort returns. Day 1, day 7, and day 30 answer different questions and should never be mixed.
Tips for a more useful estimate
- Define the cohort date and return day clearly.
- Exclude internal testers.
- Compare similar traffic sources and countries.
