Daily Usage Percentage Tracker - Statuslines

Features

• Daily usage quota tracking against configurable budget limit (default $10/day)
• Percentage of daily limit consumed with visual 20-char progress bar
• Remaining budget calculation updated in real-time
• Budget pacing indicator comparing actual vs expected usage by hour
• Automatic daily reset at midnight (date-based tracking files)
• Color-coded status (green <50%, yellow 50-80%, orange 80-100%, red >100%)
• Overflow detection and warnings when exceeding daily budget
• Persistent usage storage per day in ~/.claude-code-usage

Use Cases

• Budget management for daily Claude Code spending limits
• Preventing unexpected overspending with real-time alerts
• Tracking usage pacing throughout the day
• Setting and monitoring daily cost budgets
• Team cost allocation per developer per day
• Identifying days with abnormally high usage for analysis

Requirements

• Claude Code CLI installed and configured
• Bash shell available (bash 4.0+ recommended for arithmetic operations)
• jq command-line JSON processor (jq 1.6+ recommended for safe extraction with // defaults)
• bc calculator (bc 1.07+ required for floating point calculations - script will fail without bc)
• Terminal with ANSI color code support (256-color mode recommended for color-coded usage indicators)
• Write access to home directory (~/.claude-code-usage) for persistent daily usage tracking files

    "type": "command",

Daily Usage Percentage Tracker Installation Example

Complete setup script with usage directory creation and bc verification

#!/bin/bash
# Installation script for Daily Usage Percentage Tracker

mkdir -p .claude/statuslines

# Check for bc (required for floating point calculations)
if ! command -v bc &> /dev/null; then
  echo "Installing bc for floating point calculations..."
  if [[ "$OSTYPE" == "darwin"* ]]; then
    brew install bc
  elif [[ "$OSTYPE" == "linux-gnu"* ]]; then
    sudo apt-get install -y bc || sudo yum install -y bc
  else
    echo "Please install bc manually: https://www.gnu.org/software/bc/"
  fi
fi

# Create usage directory
mkdir -p ~/.claude-code-usage

echo "Usage directory created: ~/.claude-code-usage"

cat > .claude/statuslines/daily-usage-percentage-tracker.sh << 'SCRIPT_EOF'
#!/usr/bin/env bash
# Paste the full statusline script from the primary example above before running this installer.
SCRIPT_EOF

chmod +x .claude/statuslines/daily-usage-percentage-tracker.sh

# Add to settings.json
if [ ! -f .claude/settings.json ]; then
  echo '{"statusLine":{"type":"command","command":"$CLAUDE_PROJECT_DIR/.claude/statuslines/daily-usage-percentage-tracker.sh","refreshInterval":2000}}' > .claude/settings.json
else
  jq '.statusLine = {"type":"command","command":"$CLAUDE_PROJECT_DIR/.claude/statuslines/daily-usage-percentage-tracker.sh","refreshInterval":2000}' .claude/settings.json > .claude/settings.json.tmp
  mv .claude/settings.json.tmp .claude/settings.json
fi

echo "Daily Usage Percentage Tracker installed successfully!"
echo "Note: Set custom daily limit: export DAILY_USAGE_LIMIT=25.00 (default: $10/day)"
echo "Usage files stored in: ~/.claude-code-usage/"

Troubleshooting

Usage percentage not updating or stuck at 0%

Verify cost.total_cost_usd field exists: echo '$input' | jq .cost.total_cost_usd. Check usage file exists: cat ~/.claude-code-usage/daily-$(date +%Y-%m-%d).usage. Ensure bc is installed: which bc. Script uses simple addition - may need session deduplication for accuracy across multiple statusline updates. Verify file is writable: touch ~/.claude-code-usage/test && rm ~/.claude-code-usage/test.

Daily limit showing OVER BUDGET when under actual budget

Default DAILY_LIMIT is $10.00. Configure your actual limit in script: DAILY_LIMIT=25.00 (for $25/day budget) or export DAILY_USAGE_LIMIT=25.00. Verify limit calculation: usage_percentage = (updated_usage * 100) / DAILY_LIMIT. Check usage file value matches expected spending: cat ~/.claude-code-usage/daily-$(date +%Y-%m-%d).usage.

Usage not resetting at midnight

Script uses date-based filenames: daily-YYYY-MM-DD.usage. Each new day creates new file automatically. Old files remain for history. Check current file: ls ~/.claude-code-usage/daily-*.usage. If date command timezone incorrect, reset may occur at wrong time. Verify: date +%Y-%m-%d. Check system timezone: timedatectl (Linux) or systemsetup -gettimezone (macOS).

Pacing indicator showing incorrect ahead/below pace status

Pacing compares actual usage % vs expected % based on hours elapsed. Formula: expected = (24 - hours_remaining) * 100 / 24. At noon (12 hours), expected is 50%. If actual usage is 40%, shows 'below pace'. Adjust logic if you have non-24-hour daily windows. Verify current_hour calculation: date +%H. Check hours_remaining calculation: hours_remaining=$((24 - current_hour)).

Remaining budget showing negative or incorrect values

Remaining = DAILY_LIMIT - updated_usage. If negative, script displays '$0.00 left' and OVER BUDGET status. Verify DAILY_LIMIT setting matches your actual budget. Check updated_usage calculation: cat ~/.claude-code-usage/daily-$(date +%Y-%m-%d).usage. bc arithmetic: echo '$DAILY_LIMIT - $updated_usage' | bc. Ensure bc is working: echo '10.00 - 4.50' | bc (should return 5.50).

Multiple sessions causing duplicate cost additions

Script adds session_cost every update - can over-count if same session updates multiple times. For accuracy, track by unique session_id and update (don't add) session totals. Use enhanced version with session deduplication. Alternative: integrate with official usage API if available. Current implementation optimized for real-time awareness, not perfect accounting. Check session_id exists: echo '$input' | jq .session_id.

Progress bar showing all filled or all empty incorrectly

Verify usage_percentage calculation: usage_percentage=$(echo "scale=1; ($updated_usage * 100) / $DAILY_LIMIT" | bc). Check bar_filled calculation: bar_filled=$((usage_percentage_int / 5)) (each char = 5%). Test: usage=50%; bar_filled=$((50 / 5)); echo $bar_filled (should be 10). Verify Unicode block characters work: echo '█░'.

Usage file not being created or permission denied

Check home directory writable: touch ~/test && rm ~/test. Verify ~/.claude-code-usage directory exists: mkdir -p ~/.claude-code-usage. Check directory permissions: ls -ld ~/.claude-code-usage. Ensure script has permission to create files: touch ~/.claude-code-usage/test && rm ~/.claude-code-usage/test. Check disk space: df -h ~.
