## How to Recalculate

To recalculate budgets using the model:

```bash
cd models

# MVP Foundation (3 months)
go run ./cmd budget params.yaml --duration 3 --phase MVP-Foundation --format csv

# MVP+ (6 months)
go run ./cmd budget params.yaml --duration 6 --phase MVP+ --format csv

# Full Program (18 months)
go run ./cmd budget params.yaml --duration 18 --phase Full --format csv

# Get detailed team structure
go run ./cmd calculate params.yaml | jq '.years[0].costs.team'

# Get all year costs
go run ./cmd calculate params.yaml | jq '.years[] | {year, costs: .costs}'
```

## Key Changes from Manual Budgets

| Variant | Manual Budget | Model Calculated | Difference |
|---------|---------------|------------------|------------|
| **MVP Foundation (3m)** | €400k | €152.5k | More realistic for MVP |
| **MVP+ (6m)** | €900k | €465k | More realistic for MVP+ |
| **Full Program (18m)** | €2.5M | €1.815M | More accurate calculation |

**Note:** Model calculations are based on actual team structure and cost calculations, making them more accurate for funding applications.
