Claude Code is powerful, but it consumes tokens. Understanding billing helps optimize your costs. Let’s see how to monitor and master your budget.
Beyond financial cost, don’t forget the ecological impact of AI - every token has a carbon footprint.
The Pricing Model

/cost
Displays:
Session cost: $0.45
Input tokens: 45,000
Output tokens: 5,000
Duration: 45 minutes
Detailed Analysis
The cost breaks down as:
- Base context: CLAUDE.md, rules, configuration (~1,000-5,000 tokens)
- Files read: Variable by size (~100-10,000 tokens per file)
- Conversation: Cumulative (grows with session)
- Responses: Variable by complexity
Claude Subscriptions
Claude Pro ($20/month)
- Access to Claude.ai
- Claude Code not included (uses API)
- Priority usage on web
Claude Max ($100/month or $200/month)
Includes Claude Code with:
| Tier | Price | Tokens/day | Ideal for |
|---|---|---|---|
| Max 5x | $100/month | ~5M tokens | Moderate usage |
| Max 20x | $200/month | ~20M tokens | Heavy usage |
API Pay-as-you-go
Without Max subscription, you pay via API:
- No fixed limit
- Billed on actual usage
- Requires API key
Typical Consumption
Per Task
| Task | Estimated tokens | Sonnet 4 cost |
|---|---|---|
| Simple question | 1,000-2,000 | ~$0.01 |
| Read + analyze file | 5,000-10,000 | ~$0.03 |
| Feature implementation | 20,000-50,000 | ~$0.15 |
| Complete refactoring | 50,000-100,000 | ~$0.35 |
| Long session (2h) | 100,000-200,000 | ~$0.70 |
Per Day (Average Developer)
Morning: Exploration + planning ~30,000 tokens
Afternoon: Implementation ~80,000 tokens
Evening: Tests + fixes ~40,000 tokens
─────────────────────────────────────────────────
Daily total ~150,000 tokens
Estimated cost (Sonnet 4) ~$0.50-1.00
Anthropic Statistic
“The average developer uses ~$5-6 per day with Claude Code Max”
Optimizing Your Costs
1. Use /compact Regularly
/compact
Reduces conversation history and thus input tokens per prompt.
Rule: /compact every 30-45 minutes of active session.
2. Be Precise in Prompts
❌ Expensive (broad exploration)
> Look at the code and suggest improvements
✅ Economical (targeted)
> In @src/api/auth.ts, the validateToken function lines 45-60
can be optimized to avoid redundant DB calls
3. Use the Right Commands
| Situation | Economical command |
|---|---|
| Find a file | @file.ts instead of exploring |
| Limited context | Mention specific files |
| New task | /clear then new prompt |
4. Choose the Right Model
# For simple tasks → Haiku (8x cheaper)
claude --model haiku
# For complex tasks → Sonnet (default)
claude
# For critical tasks → Opus (5x more expensive)
claude --model opus
5. Limit File Reads
❌ Expensive
> Read all files in src/ folder and summarize
✅ Economical
> Summarize the architecture based on @src/index.ts and @CLAUDE.md

Reduce Costs Without Losing Productivity
1. Prepare Before Asking
# Before Claude session
1. Identify relevant files
2. Formulate a precise prompt
3. Gather necessary context
# During session
→ Targeted prompt = fewer tokens = cheaper
2. Use Smart Caching
Claude caches certain elements:
- CLAUDE.md (reloaded once per session)
- Recently read files
- Conversation context
Tip: Keep a session open rather than opening several.
3. Task Batching
❌ Expensive (context reloaded each time)
> Add a log here
> And also there
> And here too
✅ Economical (single request)
> Add logs in:
- @src/api/auth.ts line 45
- @src/api/users.ts line 30
- @src/middleware/error.ts line 15
