The percentage of customers who remain active over a specific time period.

Why It Matters

Retention rate determines long-term business sustainability. A 5% improvement in retention can increase profits 25-95% because retained customers cost nothing to acquire, buy more over time, and refer others. For subscription businesses, retention is literally survival—churn kills recurring revenue.

Benchmarks

A good CRR is 30-40%. Top performers achieve 50%+.

Practical Example

Scenario

A subscription box brand starts Q1 with 5,000 active subscribers, loses 1,000, gains 800 new, and ends with 4,800.

Calculation

Retention Rate = (4,800 - 800) / 5,000 = 80% (of existing customers remained)

Result

80% quarterly retention (20% churn) means they need to acquire 200 new subscribers each month just to stay flat. Improving to 90% retention would reduce required acquisition by 50%.

Pro Tips

  • 1Calculate retention by cohort to see if you're improving over time. Month 3 retention for January cohort vs June cohort.
  • 2Distinguish between different retention metrics: logo retention (% of customers) vs revenue retention (% of revenue).
  • 3Identify your 'magic moment'—the action that predicts retention. For subscription boxes, it might be completing a preference quiz.
  • 4Analyze cancellation reasons to fix root causes rather than just offering discounts to stay.

Common Mistakes to Avoid

Conflating retention rate with repeat purchase rate. Retention is period-specific (Q1 customers still active in Q2); repeat rate is cumulative.
Only measuring retention at the end of subscription terms. Track leading indicators like engagement, NPS, and usage.
Offering discounts to retain customers without addressing why they wanted to leave—you're delaying churn, not preventing it.

Frequently asked questions

CRR = ((Customers at End of Period - New Customers During Period) / Customers at Start of Period) × 100. This isolates how many of your original customers stayed, excluding new acquisition.

They're inverses. Retention Rate + Churn Rate = 100%. If you retain 80% of customers, you churned 20%. Different industries emphasize different metrics—SaaS focuses on churn, ecommerce often focuses on retention.
