## Human Labor Comparison

For ROI calculations, compare AI costs to equivalent human rates:

| Role | Hourly Rate | Task Equivalent |
|------|-------------|-----------------|
| Junior Developer | $50-75/hr | Simple bugs, chores |
| Mid Developer | $100-150/hr | Features, complex bugs |
| Senior Developer | $150-250/hr | Architecture, complex features |
| Contractor | $75-200/hr | Variable scope work |

### Breakeven Analysis

```
AI Cost = estimated_tokens × blended_rate
Human Cost = estimated_hours × hourly_rate

If AI_cost < Human_cost × confidence_factor:
  → Prefer AI approach
```

**Confidence Factors**:
- Well-defined task: 1.0x (AI likely accurate)
- Some ambiguity: 1.5x (buffer for retries)
- High uncertainty: 2.5x (expect iterations)
