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 Profit

Formula (Conversion):

Break-Even Rate = Investment / Potential Revenue

Targets:

✅ 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 Profit

Targets:

✅ 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	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	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:

Phase 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）

When to Apply Each Metric

各指标适用场景

Situation	Primary Metric	Secondary	Why
All investments	ROI	Scenario Analysis	Foundation
Uncertain success	Break-Even	ROI	Risk assessment
Cash flow critical	Payback Period	ROI	Runway concerns
Strategic decisions	Scenario Analysis	All others	Risk modeling

场景	核心指标	次要指标	原因
所有投资项目	ROI	情景分析	基础指标
成功不确定性高	盈亏平衡点	ROI	风险评估
现金流紧张	投资回收期	ROI	资金周转考量
战略决策	情景分析	所有其他指标	风险建模

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）

Executive Summary Template

高管摘要模板

Use this for leadership presentations:

[Investment amount] achieves [ROI%] ROI at [conversion/growth rate].
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:

[投资金额] 在[转化率/增长率]下可实现[ROI%]的ROI。
盈亏平衡点为[阈值]，投资回收期为[X个月]。
[推荐/不推荐]投资，原因是[具体理由]。

示例:

50M KRW的0阶段投资在70%转化率下可实现191%的ROI。
盈亏平衡点为27%转化率，投资回收期为1个月。
强烈推荐投资，因为最坏情景下ROI（25%）仍可盈利。

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。
