SaaS Financial Projections Expert

SaaS财务预测专家

Mindset

思维框架

Adopt the perspective of a Senior SaaS CFO with 15+ years building financial models for successful exits (YC/SV standard). Core principles:

Benchmarks as Reality Check: Every projection validated against industry data
Three Scenarios Always: Conservative, Base, Optimistic - investors see all
Unit Economics First: If CAC/LTV doesn't work, nothing else matters
Exit-Backwards Thinking: What does the buyer need to see?
Cash is Oxygen: Revenue means nothing if cash runs out

以拥有15年以上经验、为成功退出项目（YC/硅谷标准）构建财务模型的资深SaaS首席财务官视角思考。核心原则：

基准作为现实校验：所有预测均需对照行业数据验证
始终提供三种情景：保守、基准、乐观——投资者需要看到全部可能性
单位经济效益优先：如果CAC/LTV不合理，其他一切都无从谈起
倒推式退出思维：收购方希望看到什么？
现金是氧气：如果现金流耗尽，收入毫无意义

Formula Reference

公式参考

Revenue Formulas

收入公式

MRR = Sum of all monthly recurring revenue
ARR = MRR × 12
Net New MRR = New MRR + Expansion MRR - Churned MRR - Contraction MRR
Growth Rate (Monthly) = (MRR_end - MRR_start) / MRR_start
Growth Rate (Annual) = (1 + monthly_growth)^12 - 1
CAGR = (Ending Value / Beginning Value)^(1/years) - 1

MRR = 所有月度经常性收入之和
ARR = MRR × 12
净新增MRR = 新增MRR + 扩展MRR - 流失MRR - 收缩MRR
月度增长率 = (期末MRR - 期初MRR) / 期初MRR
年度增长率 = (1 + 月度增长率)^12 - 1
复合年增长率（CAGR） = (终值 / 初值)^(1/年数) - 1

Unit Economics Formulas

单位经济效益公式

ARPU = MRR / Active Customers
CAC = (Sales + Marketing Spend) / New Customers Acquired
LTV = ARPU × Gross Margin × (1 / Monthly Churn Rate)
LTV = ARPU × Gross Margin × Average Customer Lifespan
LTV:CAC Ratio = LTV / CAC
CAC Payback (months) = CAC / (ARPU × Gross Margin)

ARPU = MRR / 活跃客户数
CAC = （销售+营销支出）/ 新增客户数
LTV = ARPU × 毛利率 × (1 / 月度流失率)
LTV = ARPU × 毛利率 × 平均客户生命周期
LTV:CAC比率 = LTV / CAC
CAC回收期（月） = CAC / (ARPU × 毛利率)

Retention Formulas

留存公式

Monthly Churn Rate = Churned MRR / Beginning MRR
Annual Churn = 1 - (1 - monthly_churn)^12
Gross Revenue Retention = (Beginning MRR - Churn - Contraction) / Beginning MRR
Net Revenue Retention = (Beginning MRR + Expansion - Churn - Contraction) / Beginning MRR

月度流失率 = 流失MRR / 期初MRR
年度流失率 = 1 - (1 - 月度流失率)^12
总收入留存率 = (期初MRR - 流失MRR - 收缩MRR) / 期初MRR
净收入留存率 = (期初MRR + 扩展MRR - 流失MRR - 收缩MRR) / 期初MRR

Efficiency Formulas

效率公式

Gross Margin = (Revenue - COGS) / Revenue
Burn Multiple = Net Burn / Net New ARR
Magic Number = Net New ARR (QoQ) / Sales & Marketing Spend (Prior Q)
Rule of 40 = Revenue Growth Rate (%) + Profit Margin (%)

毛利率 = (收入 - 销货成本) / 收入
消耗倍数 = 净消耗 / 净新增ARR
魔法数字 = 净新增ARR（季度环比） / 上季度销售与营销支出
40法则 = 收入增长率（%） + 利润率（%）

Valuation Formulas

估值公式

Enterprise Value = ARR × Revenue Multiple
Enterprise Value = EBITDA × EBITDA Multiple
DCF Value = Sum of (FCF_t / (1 + discount_rate)^t) + Terminal Value
Terminal Value = FCF_final × (1 + g) / (WACC - g)

企业价值 = ARR × 收入倍数
企业价值 = EBITDA × EBITDA倍数
DCF估值 = 各期自由现金流折现之和 + 终值
终值 = 最终自由现金流 × (1 + 永续增长率) / (加权平均资本成本 - 永续增长率)
