- **Strategy Comparison**: Performance metrics across different approaches
- **Charts & Visualizations**: Professional charts and graphs
- **Decision Log**: Detailed rationale for optimization choices

## Installation

### PyPI Installation (Recommended)
```bash
pip install financial-debt-optimizer
```

### With Quicken Integration Support
```bash
pip install financial-debt-optimizer[balance]
```

### Requirements
- Python 3.8 or higher
- Dependencies are automatically installed with the package
- Optional: rapidfuzz or thefuzz for balance update fuzzy matching

### Install from Source
```bash
git clone https://github.com/bryankemp/financial-debt-optimizer.git
cd financial-debt-optimizer
pip install -e .
```

### Development Installation
```bash
git clone https://github.com/bryankemp/financial-debt-optimizer.git
cd financial-debt-optimizer
pip install -e .[dev]
```

## Quick Start

### 1. Create Configuration (One-time Setup)
```bash
debt-optimizer config init
```

This creates `~/.debt-optimizer/config.yaml` with default settings. Edit it to set:
- Input/output file paths
- Quicken database location
- Optimization preferences
- Balance update settings

### 2. Generate an Excel Template
```bash
debt-optimizer generate-template my-debt-data.xlsx
```

### 3. Fill in Your Data
Open `my-debt-data.xlsx` and fill in:
- **Debts**: Name, balance, minimum payment, interest rate, due date
- **Income**: Sources, amounts, frequency (bi-weekly, monthly, etc.)
- **Recurring Expenses**: Monthly bills, subscriptions, etc.
- **Future Income**: Bonuses, raises, additional income streams
- **Settings**: Bank balance, optimization preferences

### 4. Update Balances from Quicken (Optional)
```bash
debt-optimizer update-balances --db ~/Documents/MyQuicken.quicken/data --xlsx my-debt-data.xlsx
```

Or update automatically during analysis with the `-u` flag.

### 5. Run Analysis
```bash
debt-optimizer analyze -u --input my-debt-data.xlsx --output debt-analysis.xlsx
```

The `-u` flag automatically updates balances from Quicken before analyzing.

### 6. Review Results
Open `debt-analysis.xlsx` to see:
- Optimized payment strategy
- Month-by-month payment schedule
- Visual charts and progress tracking
- Interest savings and time to debt freedom

## Usage Examples

### Configuration Management
```bash
# Create configuration file
debt-optimizer config init

# View current settings
debt-optimizer config show

# Get specific setting
debt-optimizer config get input_file

# Set value
debt-optimizer config set extra_payment 500.0
```

### Balance Updates
```bash
# Update balances using config defaults
debt-optimizer update-balances

# Update with custom paths
debt-optimizer update-balances \
    --db ~/Documents/MyQuicken.quicken/data \
    --xlsx my-debts.xlsx \
    --threshold 85

# Skip backup creation
debt-optimizer update-balances --no-backup
```

### Basic Analysis
```bash
# Analyze using config defaults
debt-optimizer analyze

# Analyze with balance update
debt-optimizer analyze -u

# Override config defaults
debt-optimizer analyze -i my-debts.xlsx -o results.xlsx
```

### Advanced Analysis
```bash
# Full workflow: update balances, compare all strategies
debt-optimizer analyze -u \
    --input my-debts.xlsx \
    --output comprehensive-analysis.xlsx \
    --goal minimize_interest \
    --extra-payment 500 \
    --compare-strategies

# Generate simple one-sheet report
debt-optimizer analyze -u --simple-report
```

### Available Goals
- `minimize_interest`: Pay least total interest (default)
- `minimize_time`: Become debt-free fastest
- `maximize_cashflow`: Optimize monthly cash flow
