Core Financial Metrics (Quick Reference)
核心财务指标（快速参考）
1. ROI (Return on Investment)
1. ROI（投资回报率）
Formula:
ROI = (Net Profit / Total Investment) × 100%Targets:
- ✅ INVEST: ROI > 100% (realistic case)
- ⚠️ REVIEW: ROI 50-100%
- ❌ REJECT: ROI < 50%
Example:
Investment: 100M KRW
Revenue: 200M KRW
Operating Costs: 50M KRW
Net Profit: 200M - 50M - 100M = 50M KRW
ROI: (50M / 100M) × 100% = 50% ⚠️ REVIEW公式：
ROI = (Net Profit / Total Investment) × 100%判定标准:
- ✅ 投资：ROI > 100%（现实情景）
- ⚠️ 复审：ROI 50-100%
- ❌ 否决：ROI < 50%
示例:
投资金额: 100M KRW
营收: 200M KRW
运营成本: 50M KRW
净利润: 200M - 50M - 100M = 50M KRW
ROI: (50M / 100M) × 100% = 50% ⚠️ 复审2. Break-Even Point
2. 盈亏平衡点
Formula (Project):
Break-Even = Investment / Monthly Net ProfitFormula (Conversion):
Break-Even Rate = Investment / Potential RevenueTargets:
- ✅ INVEST: Break-even < 50% of realistic target
- ⚠️ REVIEW: Break-even 50-70% (low margin for error)
- ❌ REJECT: Break-even > 70% (unrealistic)
Example:
Phase 0 Investment: 50M KRW
Phase 1 Contract: 200M KRW
Break-Even: 50M / 200M = 25% conversion needed ✅（项目）公式：
Break-Even = Investment / Monthly Net Profit（转化率）公式：
Break-Even Rate = Investment / Potential Revenue判定标准:
- ✅ 投资：盈亏平衡点 < 现实目标的50%
- ⚠️ 复审：盈亏平衡点 50-70%（容错空间小）
- ❌ 否决：盈亏平衡点 > 70%（不现实）
示例:
0阶段投资金额: 50M KRW
1阶段合同金额: 200M KRW
盈亏平衡点: 50M / 200M = 25% 转化率要求 ✅3. Payback Period
3. 投资回收期
Formula:
Payback = Investment / Monthly Net ProfitTargets:
- ✅ INVEST: Payback < 12 months
- ⚠️ REVIEW: Payback 12-24 months
- ❌ REJECT: Payback > 24 months
公式：
Payback = Investment / Monthly Net Profit判定标准:
- ✅ 投资：回收期 < 12个月
- ⚠️ 复审：回收期 12-24个月
- ❌ 否决：回收期 > 24个月
4. Scenario Analysis (Best/Realistic/Worst)
4. 情景分析（最佳/现实/最坏）
Purpose: Test assumptions and de-risk decisions by modeling multiple outcomes.
Decision Rule: If worst-case ROI ≥ 0%, investment is low-risk
Output Template:
| Case | Assumptions | Revenue | Profit | ROI | Assessment |
|---|---|---|---|---|---|
| Worst | [Pessimistic] | ⚠️ Risk level | |||
| Realistic | [Expected] | ✅ Target | |||
| Best | [Optimistic] | ✅ Upside |
用途：通过建模多种结果测试假设，降低决策风险。
决策规则：若最坏情景下ROI ≥ 0%，则该投资为低风险
输出模板:
| 情景 | 假设条件 | 营收 | 利润 | ROI | 评估 |
|---|---|---|---|---|---|
| 最坏 | [悲观假设] | ⚠️ 风险等级 | |||
| 现实 | [预期假设] | ✅ 目标值 | |||
| 最佳 | [乐观假设] | ✅ 上升空间 |
Quick Start Example
快速入门示例
Scenario: Phase 0 → Phase 1 Investment Decision
场景：0阶段 → 1阶段投资决策
User: "Should we invest 50M KRW in a 1-month Phase 0 trial? Phase 1 contract would be 208M KRW if we convert."
Analysis:
markdown
undefined用户："我们是否应该投资50M KRW进行为期1个月的0阶段试用？如果转化成功，1阶段合同金额为208M KRW。"
分析:
markdown
undefinedPhase 0 Investment Analysis
0阶段投资分析
Investment: 50M KRW (1 month)
Potential Revenue: 208M KRW (Phase 1, if convert)
投资金额: 50M KRW（1个月）
潜在营收: 208M KRW（若转化成功的1阶段合同）
Scenario Analysis
情景分析
| Case | Conversion | Revenue | Profit | ROI |
|---|---|---|---|---|
| Worst | 30% | 62.4M | 12.4M | 25% ⚠️ |
| Realistic | 70% | 145.6M | 95.6M | 191% ✅ |
| Best | 90% | 187.2M | 137.2M | 274% ✅ |
Break-Even: 27% conversion rate (very achievable)
Decision: ✅ INVEST
- Realistic ROI 191% is excellent
- Even worst-case 25% ROI is profitable
- Break-even 27% << realistic 70% (low risk)
---| 情景 | 转化率 | 营收 | 利润 | ROI |
|---|---|---|---|---|
| 最坏 | 30% | 62.4M | 12.4M | 25% ⚠️ |
| 现实 | 70% | 145.6M | 95.6M | 191% ✅ |
| 最佳 | 90% | 187.2M | 137.2M | 274% ✅ |
盈亏平衡点: 27% 转化率（极易达成）
决策: ✅ 投资
- 现实情景下ROI达191%，表现优异
- 即使最坏情景下ROI为25%，仍可盈利
- 盈亏平衡点27% << 现实预期70%（低风险）

Key Principles
核心原则
Always Include:
- 3 scenarios (Best/Realistic/Worst), not just one optimistic case
- Break-even threshold to understand minimum success rate
- Time value (for 2+ year projects, apply discount rate)
- Operating costs (dev, ops, marketing, support) - not just investment
- Decision recommendation (INVEST/REVIEW/REJECT with clear reasoning)
Never:
- Use only "best case" (always model downside risk)
- Ignore operating costs (they compound over time)
- Forget sensitivity analysis (what if assumptions wrong?)
- Make decisions on ROI alone (consider payback, break-even)
必须包含:
- 三种情景（最佳/现实/最坏），而非仅乐观情景
- 盈亏平衡点阈值，明确最低成功率要求
- 时间价值（对于周期2年以上的项目，应用贴现率）
- 运营成本（开发、运维、营销、支持）- 不可仅考虑投资金额
- 决策建议（投资/复审/否决，并附清晰理由）
绝对禁止:
- 仅使用“最佳情景”（务必建模下行风险）
- 忽略运营成本（成本会随时间累积）
- 忘记敏感性分析（若假设错误会怎样？）
- 仅依据ROI做决策（需结合回收期、盈亏平衡点）

Break-even occurs at [threshold], with payback in [months].
Investment is [recommended/not recommended] [because reason].Example:
50M KRW Phase 0 investment achieves 191% ROI at 70% conversion.
Break-even occurs at 27% conversion, with payback in 1 month.
Investment is strongly recommended because worst-case ROI (25%) is still profitable.适用于领导层汇报:

Meta Note
元注释
After applying this analysis, always reflect:
- What assumptions are most critical? (Test with sensitivity analysis)
- What data gaps exist? (Customer interviews, market research needed?)
- What alternatives weren't considered? (Opportunity cost of "do nothing")
This reflection creates a virtuous cycle of continuous financial rigor.
For detailed usage and examples, see related documentation files.
完成分析后，务必反思:
- 哪些假设最为关键？（通过敏感性分析测试）
- 存在哪些数据缺口？（是否需要客户访谈、市场调研？）
- 哪些替代方案未被考虑？（“不行动”的机会成本）
这种反思能形成持续提升财务严谨性的良性循环。
