The NRR Headline Can Be Misleading
Your Net Revenue Retention (NRR): 115% – sounds excellent.
At first glance: existing customers are expanding faster than they are churning.
But that single number hides important trends.
Cohort Analysis Reveals the Real Story
Breaking NRR down by cohort:
2023 cohort: 95% NRR → slight contraction
2024 cohort: 125% NRR → strong expansion
2025 cohort: 140% NRR → new, minimal churn
Blended 115% NRR is just the average.
Key Insight:
Mature cohorts are contracting, while overall growth relies on newer cohorts that haven’t matured yet.
Why Blended NRR Can Be Dangerous
If the pattern continues, the 2025 cohort will eventually contract as it matures.
Blended NRR masks retention deterioration in older cohorts.
Relying only on new cohorts can create an expansion cliff in the future.
The Right Way to Use NRR
Measure NRR by cohort, not blended across all customers.
Understand why older cohorts are contracting:
Product usage
Customer satisfaction
Support or onboarding gaps
Design interventions to improve mature cohort retention.
Don’t just rely on new cohort expansion to carry your growth.
Take Action Early
Companies that analyze cohort trends early can:
Prevent future churn acceleration
Sustain long-term expansion
Allocate retention resources where it matters most
