Revenue Metrics
营收指标
Monthly Recurring Revenue (MRR)
MRR = (Total paid customers) × (average subscription price)
Growth MRR = New MRR + Expansion MRR - Churn MRRAnnual Run Rate (ARR)
ARR = MRR × 12Average Revenue Per User (ARPU)
ARPU = MRR / Total UsersCustomer Lifetime Value (LTV)
LTV = (ARPU × Gross Margin %) / Monthly Churn %
Example:
ARPU: $100
Gross Margin: 80%
Monthly Churn: 5%
LTV = ($100 × 80%) / 5% = $1,600
If CAC = $400: LTV/CAC = 4x ✓ (target: 3x+)月度经常性收入(MRR)
MRR = (付费用户总数) × (平均订阅价格)
Growth MRR = New MRR + Expansion MRR - Churn MRR年度经常性收入(ARR)
ARR = MRR × 12每用户平均收入(ARPU)
ARPU = MRR / 总用户数客户生命周期价值(LTV)
LTV = (ARPU × 毛利率 %) / 月度流失率 %
示例:
ARPU: $100
Gross Margin: 80%
Monthly Churn: 5%
LTV = ($100 × 80%) / 5% = $1,600
如果CAC = $400: LTV/CAC = 4倍 ✓(目标:3倍+)Dashboard Architecture

Statistical Significance
统计显著性
Confidence Level: 95% (industry standard)
- Means 5% chance of false positive

P-Value: Probability result is random chance
- P < 0.05: Statistically significant
- P > 0.05: Not significant, inconclusive
置信水平: 95%(行业标准)
- 意味着有5%的概率出现假阳性结果
- 需要足够的样本量(通常每个变体1000-10000用户)
- 使用计算器确定精确样本量
P值: 结果由随机因素导致的概率
- P < 0.05:具备统计显著性
- P > 0.05:无显著性,结果不确定

Metric Pitfalls to Avoid
需避免的指标陷阱
Vanity Metrics
虚荣指标
❌ "We have 1M page views!"
✓ "We have 50K daily active users, growing 10% monthly"
❌ “我们有100万页面浏览量!”
✓ “我们有5万日活跃用户,月增长10%”
Actionable vs Non-Actionable
可行动 vs 不可行动
❌ "User satisfaction increased" (what changed?)
✓ "Onboarding completion rate 65% → 78% (↑20%)" (clear action)
❌ “用户满意度提升了”(什么因素导致的?)
✓ “新手引导完成率从65%提升至78%(↑20%)”(明确可行动)
Correlation vs Causation
相关性 vs 因果性
❌ "Ice cream sales correlate with drownings"
✓ Understand actual causation, not just correlation
❌ “冰淇淋销量与溺水事件相关”
✓ 理解真实的因果关系,而非仅看相关性
Look-Alike Metrics
相似指标误区
❌ Track MRR but not Customer LTV (can grow MRR by spending more on acquisition)
✓ Track both acquisition efficiency AND retention
❌ 仅追踪MRR而不追踪客户LTV(可以通过增加获客投入来提升MRR)
✓ 同时追踪获客效率与留存情况
