## 📊 Key Financial Metrics

### 1. ROI (Return on Investment)

```
ROI = (Net Profit / Total Investment) × 100%

Where: Net Profit = Total Benefits - Total Costs

Target: > 100% is good, > 200% is excellent
```

### 2. Payback Period

```
Payback Period = Total Investment / Annual Net Benefit

Target: < 2 years for startups, < 3 years for enterprise
```

### 3. BCR (Benefit-Cost Ratio)

```
BCR = Total Benefits / Total Costs

Target: > 1.0 (benefits outweigh costs)
```
