Claude Code Cost Calculator - Analyze token usage and costs from Claude Code history

Claude Code Cost Calculator

A Python tool for analyzing Claude Code usage history, calculating token consumption and costs across projects and time periods.

English | 中文

Features

• Multi-model Support: Claude Sonnet, Opus, Gemini models with accurate pricing
• Advanced Deduplication: Intelligent duplicate detection removes repeated API responses from streaming/retry mechanisms and session continuation errors
• Comprehensive Analytics: Daily usage trends, project rankings, model performance, and cost breakdowns
• Smart Display: Automatically hides empty sections and optimizes long project paths
• Model Insights: Individual model consumption tracking with cost ranking (shown when using 2+ models)
• Data Export: JSON export for further analysis
• Time Zone Handling: Converts UTC timestamps to local time for accurate daily statistics
• Internationalization: Auto-detects system language, supports English and Chinese (Simplified/Traditional)

Installation

Quick Install (One-liner)

# Auto-detect best installation method for your system
curl -sSL https://raw.githubusercontent.com/keakon/claude-code-cost/main/install.sh | bash

Option 1: Install from PyPI (Recommended)

Using uv (Recommended - Modern & Fast)

# Install uv if you don't have it
curl -LsSf https://astral.sh/uv/install.sh | sh

# Install as a global tool
uv tool install claude-code-cost

# Run the command
ccc

Using pipx (Traditional alternative)

# Install pipx if you don't have it
brew install pipx  # macOS
# or: python -m pip install --user pipx  # Linux/Windows

# Install claude-code-cost as an isolated tool
pipx install claude-code-cost

# Now you can run from anywhere
ccc

Using pip with virtual environment

# Create a dedicated virtual environment
python -m venv ~/.venvs/claude-cost
source ~/.venvs/claude-cost/bin/activate  # Linux/macOS
# or: ~/.venvs/claude-cost/Scripts/activate  # Windows

pip install claude-code-cost
ccc

Option 2: Install from Source

# Clone the repository
git clone https://github.com/keakon/claude-code-cost.git
cd claude-code-cost

# Install in development mode (uv recommended)
uv pip install -e .

# Or using pip
pip install -e .

Requirements

• Python 3.8+
• Dependencies: rich, pyyaml

Usage

Basic Usage

# Analyze with default settings (after installing from PyPI)
ccc

# Or if installed from source
uv run ccc

# Specify custom data directory

# Force Chinese interface
ccc --language zh

Output Sections

The tool displays up to 5 main sections:

1. Overall Statistics: Total projects, tokens, and costs
2. Today's Usage: Current day consumption by project (shown only when active)
3. Daily Statistics: Historical trends (shown only when historical data exists)
4. Project Rankings: Top projects by cost
5. Model Statistics: Individual model consumption and ranking (shown when using 2+ models)

Configuration

The tool comes with built-in default pricing for all supported models, but you can customize pricing by creating a user configuration file.

Custom Configuration

Create a configuration file at ~/.claude-code-cost/model_pricing.yaml to override default settings:

# Create config directory
mkdir -p ~/.claude-code-cost

# Create your custom configuration
cat > ~/.claude-code-cost/model_pricing.yaml << 'EOF'
# Custom model pricing configuration
currency:
  usd_to_cny: 7.3        # Exchange rate
  display_unit: "USD"    # Default display currency

pricing:
  sonnet:
    input_per_million: 3.0
    output_per_million: 15.0
    cache_read_per_million: 0.3
    cache_write_per_million: 3.75

  gemini-2.5-pro:
    # Multi-tier pricing example
    tiers:
      - threshold: 200000    # ≤200K tokens
        input_per_million: 1.25
        output_per_million: 10.0
      - # >200K tokens
        input_per_million: 2.5
        output_per_million: 15.0

  qwen3-coder:
    # CNY pricing example
    currency: "CNY"
    tiers:
      - threshold: 32000     # ≤32K tokens
        input_per_million: 4.0
        output_per_million: 16.0
      - threshold: 128000    # ≤128K tokens
        input_per_million: 6.0
        output_per_million: 24.0
      - threshold: 256000    # ≤256K tokens
        input_per_million: 10.0
        output_per_million: 40.0
      - # >256K tokens
        input_per_million: 20.0
        output_per_million: 200.0
EOF
