Key Concepts
Net Promoter Score (NPS)
Net Promoter Score measures customer loyalty by asking one question: "How likely are you to recommend us to a friend or colleague?" on a 0-10 scale. Respondents are classified as Promoters (9-10), Passives (7-8), or Detractors (0-6). NPS equals the percentage of Promoters minus the percentage of Detractors, ranging from -100 to +100. Scores above 0 indicate more promoters than detractors, while scores above 50 are considered excellent. Track NPS over time to measure the impact of product improvements on customer satisfaction.

Product-market fit (PMF) occurs when your product satisfies strong market demand—customers actively want what you're building. Measure PMF through multiple signals: retention rates (do users come back?), NPS scores (do they recommend you?), organic growth (do they tell others?), and the Sean Ellis test (would users be "very disappointed" without your product?). Strong PMF typically shows 40%+ users responding "very disappointed" to losing access. Without PMF, growth investments yield diminishing returns.

User retention rate measures the percentage of users who continue using your product over time. Calculate retention by dividing the number of users active at the end of a period by the number at the start (excluding new users). Track cohort-based retention to understand how different user groups behave. Day-1, Day-7, and Day-30 retention are common benchmarks. Consumer apps typically see 20-40% retention after 90 days, while B2B SaaS products achieve 80-95% monthly retention.

Customer Lifetime Value represents the total revenue a customer generates over their entire relationship with your company. For subscription businesses, CLV equals average monthly revenue divided by monthly churn rate. For transaction-based businesses, multiply average order value by purchase frequency and customer lifespan. Compare CLV against customer acquisition cost (CAC)—healthy businesses maintain CLV:CAC ratios of 3:1 or higher. Improving retention is often the fastest path to increasing CLV.
