TL;DR
Retention rate is the percentage of users or customers from a starting cohort who remain active at a defined later point — e.g., 60% Day 30 retention means 60 of every 100 new users are still active 30 days later. For B2B SaaS, healthy annual customer retention is 88-95% (gross). For consumer apps, Day 30 retention varies massively by category — 40%+ is best-in-class consumer social.
What is retention rate?
Retention rate is the percentage of users or customers from a starting cohort who are still active at a defined later point in time. Formula: (active users at end of period) / (users at start of period) × 100. For B2B SaaS, it is typically measured at the annual cohort level (12-month retention); for consumer apps, at Day 1, Day 7, Day 30, Day 90.
Retention rate is the single-point snapshot version of a retention curve. The two are complementary: retention rate is the headline number for reporting; the curve shows the trajectory.
Why retention rate matters
Retention is the single most important determinant of SaaS valuation, LTV, and CAC efficiency. A 95% annual retention rate with 110% NRR produces dramatically different unit economics than 80% retention with 100% NRR — even at the same growth rate. Compounded over 5 years, the difference is 2-3× in customer LTV.
For consumer apps, retention rate is the single best PMF signal. Andreessen Horowitz benchmark research consistently shows that consumer products with sub-30% Day 30 retention almost never reach scale. Best-in-class consumer apps achieve 40%+ Day 30 retention.
Retention rate formula
Retention Rate (%) = (Active users at end of period /
Active users at start of period) × 100
Example (B2B SaaS, annual cohort):
- January 2025 cohort: 200 customers signed up
- January 2026: 178 still active
Annual customer retention rate = 178 / 200 = 89%
Note:
- Gross retention excludes expansion and re-acquisition
- Net retention includes expansion (= NRR)
- Always specify which variant you are reporting Benchmarks
| Context | Best-in-class | Median | Concerning |
|---|---|---|---|
| B2B SaaS gross (annual) | 92-97% | 85-92% | <80% |
| B2B SaaS net (NRR) | 120-150% | 100-115% | <95% |
| B2C subscription (annual) | 70-85% | 50-65% | <40% |
| Consumer social (Day 30) | 40-65% | 20-35% | <15% |
| E-commerce (annual) | 30-50% | 15-30% | <10% |
| Mobile games (Day 30) | 20-35% | 10-18% | <8% |

Common mistakes
- Mixing gross and net retention. Net retention includes expansion (= NRR); gross excludes it. Always specify which.
- Single-point reporting without curve. A 60% Day 90 retention could be a healthy plateau or a still-declining cohort. Always report alongside the retention curve.
- Blending segments. Enterprise often retains 95%+; SMB often retains 70-80%. Blended retention hides which segment is the problem.
- Different "active" definitions. "Paid customer" vs. "logged in" vs. "completed key action" produce very different retention rates. Use one definition consistently.

Frequently asked questions
What is retention rate?
Retention rate is the percentage of users or customers from a starting cohort who remain active at a defined later point. Formula: (active at end) / (active at start) × 100. The single-point version of a retention curve.
What is a good retention rate?
B2B SaaS: 92-97% gross annual retention is best-in-class. Consumer subscription: 70-85% annual. Consumer social Day 30: 40%+ best-in-class. Always benchmark within category and use case.
What's the difference between retention rate and churn rate?
Mathematically complementary: retention + churn = 100% within a defined period. A 92% retention rate = 8% churn rate. The two are interchangeable but conventional contexts differ — retention is the headline metric for product and CS; churn is the headline metric for finance and investors.
How do you improve retention rate?
First identify where retention drops (use a retention curve). Then match fix to failure mode: early-stage drop = onboarding; mid-cycle drop = value delivery; late-cycle drop = competitive or pricing. Generic 'improve retention' programs without diagnosis waste effort.
