Frequently Asked Questions

What is customer retention rate and how do I calculate it correctly?

Customer Retention Rate (CRR) measures the percentage of customers a business retains over a specific period.

Formula: CRR = ((E - N) / S) × 100, where S = customers at start, E = customers at end, N = new customers acquired.

Example: Start with 500 customers, end with 520, acquired 80 new.

CRR = ((520-80)/500) × 100 = 88%.

Industry benchmarks 2025: SaaS 90-95% monthly, E-commerce 30-40% annual, Subscription boxes 60-70% quarterly, Streaming 75-85% monthly.

Track cohort retention, revenue retention (NRR 100-120% best-in-class), and segment by customer type (enterprise 95%+ vs SMB 70-80%).

How can I improve customer retention and what ROI should I expect?

Retention improvements generate 5-10x ROI vs acquisition.

Top strategies: (1) Improve onboarding (20-40% lift, time-to-value <7 days), (2) Proactive customer success (15-30% churn reduction, health scoring + trigger-based outreach), (3) Payment recovery (30-50% of failed payments, 500-1000% ROI), (4) Loyalty programs (10-20% lift), (5) Annual contracts with incentives (locks revenue, 60-80% renewal vs 28% annual from monthly).

Investment example: $400K/year (customer success team + software) → $2.5M revenue over 3 years. 5% retention improvement = $600K annual revenue impact.

Prioritize onboarding first (highest ROI), then payment recovery (quick wins), then customer success team.
