| Metric | Why It Matters | Good Signal |
|--------|---------------|-------------|
| **MRR/ARR** | Revenue traction | Any consistent revenue |
| **MoM Growth** | Trajectory | 15-20%+ MoM |
| **Retention** | PMF indicator | >80% monthly retention |

第 2 步:计算核心 SaaS 指标
## Metric Calculations
### Revenue Metrics
**MRR (Monthly Recurring Revenue):**
MRR = Sum of all recurring revenue per month
**ARR (Annual Recurring Revenue):**
ARR = MRR × 12
**MRR Components:**
- New MRR: Revenue from new customers
- Expansion MRR: Upgrades and cross-sells
- Contraction MRR: Downgrades
- Churned MRR: Lost customers
**Net New MRR:**
Net New MRR = New + Expansion - Contraction - Churned
---
### Growth Metrics
**MoM Growth Rate:**
Growth = (MRR this month - MRR last month) / MRR last month × 100
**YoY Growth Rate:**
YoY = (ARR this year - ARR last year) / ARR last year × 100
**CMGR (Compound Monthly Growth Rate):**
CMGR = (Ending MRR / Starting MRR)^(1/months) - 1
---
### Retention Metrics
**Gross Revenue Retention (GRR):**
GRR = (MRR - Churned MRR - Contraction MRR) / MRR × 100
Maximum: 100% (doesn't include expansion)
**Net Revenue Retention (NRR) / Net Dollar Retention (NDR):**
NRR = (MRR + Expansion - Contraction - Churned) / MRR × 100
Can be >100% (good!)
**Logo Churn:**
Logo Churn = Customers lost / Customers at start of period × 100
**Revenue Churn:**
Revenue Churn = Churned MRR / MRR at start of period × 100
---
### Unit Economics
**Customer Acquisition Cost (CAC):**
CAC = Total Sales & Marketing Spend / New Customers Acquired
**Lifetime Value (LTV):**
Simple: LTV = ARPU × Gross Margin × Customer Lifetime
With churn: LTV = (ARPU × Gross Margin) / Monthly Churn Rate
**LTV/CAC Ratio:**
LTV/CAC = LTV / CAC
Good: >3:1
**CAC Payback Period:**
Payback = CAC / (ARPU × Gross Margin)
Good: <18 months
---
### Efficiency Metrics
**Magic Number:**
Magic Number = Net New ARR this quarter / S&M Spend last quarter
>1.0 = Very efficient
0.75-1.0 = Good
<0.5 = Inefficient
**Rule of 40:**
Rule of 40 = Revenue Growth Rate + Profit Margin
>40% = Healthy balance of growth and profitability
**Burn Multiple:**
Burn Multiple = Net Burn / Net New ARR
<1x = Excellent
1-2x = Good
>2x = Concerning
**Quick Ratio:**
Quick Ratio = (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR)
>4 = Excellent growth quality
第 3 步:与行业标准对比

第 4 步:诊断问题
## Metric Diagnosis Guide
### If MRR Growth is Slowing...
**Possible causes:**
1. Market saturation (ran out of easy customers)
2. Product-market fit weakening (competition, changing needs)
3. Sales inefficiency (declining magic number)
4. High churn eating new growth
**Diagnostic questions:**
- Is logo churn increasing?
- Is CAC increasing?
- Is conversion rate declining?
- Is expansion revenue flat?
---
### If Churn is High...
**Possible causes:**
1. Onboarding problems (never got value)
2. Product gaps (missing critical features)
3. Wrong customers (sold to people who shouldn't buy)
4. Competition (better alternatives emerged)
5. Pricing mismatch (not worth it)
**Diagnostic questions:**
- When do customers churn? (early = onboarding, late = value)
- What's the churn reason? (survey departures)
- Which segments churn most?
- What's usage pattern before churn?
---
### If CAC is Too High...
**Possible causes:**
1. Wrong channel (expensive acquisition)
2. Poor targeting (low conversion)
3. Weak positioning (hard to differentiate)
4. Long sales cycles (expensive process)
5. Market competition (bidding up costs)
**Diagnostic questions:**
- What's CAC by channel?
- What's conversion rate at each stage?
- How long is sales cycle?
- What's win rate vs. competition?
---
### If LTV is Too Low...
**Possible causes:**
1. High churn (short lifetime)
2. Low ARPU (underpriced or wrong segment)
3. No expansion revenue (no upsell path)
4. Low gross margin (cost too high)
**Diagnostic questions:**
- What's average customer lifespan?
- What's ARPU distribution?
- What's expansion revenue %?
- Are costs scaling with revenue?
---
### Quick Diagnostic Table
| Symptom | Primary Metric | Secondary Checks |
|---------|---------------|------------------|
| Revenue plateau | MRR growth rate | New vs. expansion breakdown |
| Customers leaving | Churn rate | Cohort analysis, exit surveys |
| Expensive growth | CAC, Magic Number | Channel efficiency, conversion |
| Low profitability | Gross margin | COGS breakdown, pricing |
| "Leaky bucket" | Quick Ratio | Churn + expansion balance |

示例
示例 1:种子轮阶段指标分析
输入:
“我正在筹集种子轮资金。这些是我的指标,表现如何?” MRR:$15K,成立 6 个月,40 个客户 月环比增长:平均 20% 流失率:每月 5% CAC:$200
输出:
指标分析:种子轮阶段
当前情况
| 指标 | 数值 | 基准 | 评估 |
|---|---|---|---|
| MRR | $15K | - | 处于早期,但表现积极 |
| 月环比增长 | 20% | 15-25% | ✅ 良好 |
| 客户数量 | 40 | - | 符合当前阶段的合理水平 |
| 月流失率 | 5% | <5% | ⚠️ 达到阈值 |
| CAC | $200 | <$500 SMB | ✅ 效率高 |
计算得出的指标
ARPU: $15,000 / 40 = $375/月
估算 LTV(简易算法):
- 客户生命周期:1 / 0.05 = 20 个月
- LTV = $375 × 20 = $7,500
LTV/CAC: $7,500 / $200 = 37.5:1 ✅ 优秀
CAC 回本周期: $200 / $375 = 0.5 个月 ✅ 优秀
分析
优势:
- 增长率健康(月环比增长 20% = 年化增长 8.9 倍)
- CAC 效率很高
- LTV/CAC 表现强劲(不过流失率可能受早期阶段数据波动影响)
顾虑:
- 月流失率为 5% = 年流失率为 60%(对 SaaS 来说偏高)
- 样本量小(40 位客户)
- 需要查看客户群留存情况,才能了解真实流失率
需要回答的问题:
- 5% 的流失率在各客户群中是否一致,还是有所改善?
- 激活率是多少?(流失的客户是否曾从中获得价值?)
- 留存客户的使用模式是怎样的?
投资者准备情况
要进行种子轮融资,你需要展示:
- ✅ 增长轨迹(月环比增长 20% 表现不错)
- ✅ 高效获客
- ⚠️ 留存情况(需要客户群数据)
- ❓ 规模化路径
建议:
- 突出增长和 CAC 效率
- 如果近期客户群的留存率更高,则展示客户群数据
- 说明你正在采取哪些措施来提高留存率
- 预测留存率提升后各项指标会达到什么水平
增长预测
| 指标 | 当前 | +6 个月(月环比增长 20%) | +12 个月 |
|---|---|---|---|
| MRR | $15K | $45K | $133K |
| ARR | $180K | $540K | $1.6M |
| 客户数 | 40 | ~100 | ~250 |
示例 2:诊断增长下滑
输入:
“我的月环比增长在 4 个月内从 25% 降到了 8%。发生了什么?”
输出:
增长下滑诊断
所需数据
| 指标 | 4 个月前 | 当前 | 变化 |
|---|---|---|---|
| 新增 MRR | ? | ? | |
| 扩张 MRR | ? | ? | |
| 流失 MRR | ? | ? | |
| 客户流失率 | ? | ? | |
| 新客户数 | ? | ? | |
| 销售管道 | ? | ? | |
| CAC | ? | ? | |
| 转化率 | ? | ? |
诊断框架
问题 1:这是一个漏水桶问题吗?
- 获得的客户数量是否相同,但流失的客户更多?
- 检查:新增 MRR 与流失 MRR
问题 2:这是一个获客问题吗?
- 获得的新客户是否变少了?
- 检查:新客户数、销售管道、转化率
问题 3:这是一个扩张问题吗?
- 扩张收入是否放缓?
- 检查:扩张 MRR 趋势、追加销售率
常见情形
情形 A:流失增加 症状:新增 MRR 稳定,但流失 MRR 增长 原因:产品问题、客户不匹配、竞争 解决方案:流失分析、客户成功、产品修复
情形 B:新客户获取放缓 症状:流失 MRR 稳定,但新增 MRR 下降 原因:市场饱和、CAC 上升、营销效率下降 解决方案:开拓新渠道、调整定位、优化销售
情形 C:扩张停滞 症状:新增和流失情况稳定,但扩张收入下降 原因:产品限制、缺少追加销售路径、客户饱和 解决方案:推出新功能、设置价格层级、加强客户管理
情形 D:多种因素共同作用 通常是多种因素共同作用——增长会掩盖问题,直到增速放缓
调查清单
□ Break down MRR: New, Expansion, Contraction, Churned
□ Compare ratios: Quick Ratio trend
□ Cohort analysis: Are newer cohorts worse?
□ Channel breakdown: Which channels slowed?
□ Segment analysis: Which customer type slowed?
□ Funnel metrics: Where is conversion dropping?
□ Win/loss analysis: Why are deals not closing?
□ Churn interviews: Why are customers leaving?
后续步骤
- 获取数据明细(见上表)
- 确定主要驱动因素(获客、流失或扩张)
- 对该驱动因素进行根因分析
- 提出假设并测试解决方案
- 每周监控先行指标
示例 3:评估是否具备 Series A 融资条件
输入:
“我准备好进行 Series A 融资了吗?ARR:$1.2M,NRR:108%,LTV/CAC:4.5x,年同比增长:180%”
输出:
