Retention Rate
Share of users who remain active between periods.
Overview
Retention rate shows the share of users who remain active across periods. It reveals whether value persists beyond initial adoption.
Retention rate is the percentage of users/accounts still active at the end of a period relative to the start cohort.
Definition
Use cohort curves to see decay and where they flatten. High, stable retention underpins sustainable growth and compounding economics.
Retention rate is the percentage of users still active at the end of a period relative to the start cohort. Plot cohort curves monthly to understand decay and where the curve flattens. High, stable retention underpins all sustainable growth and ensures marketing investments compound over time.
Formula
Track active users across periods.
Divide end‑of‑period active users by the start‑of‑period cohort and express as a percentage.
Retention = users active end / users active start × 100%
Example
500 at start, 380 at end → 76%.
Present a cohort example with monthly measurements to show where the curve stabilizes.
Common pitfalls
Comparing different cohorts, using cumulative retention, or counting reactivations as retained can mislead.
- Comparing different cohorts
- Using cumulative instead of period retention
- Counting reactivations as retained
- Mixing DAU/WAU/MAU baselines
Benchmarks
Benchmarks vary by category; healthy cohorts often flatten after 3–6 months.
Healthy cohorts often flatten after 3–6 months depending on category and use case.
Notes
Plot cohort curves monthly and use survival analysis for more precise insights.
