What Is GitHub Copilot Token Billing? How Credits Work and How to Estimate Your Monthly Bill
June 1, 2026 · 7 min read
Token Billing: The Basics
As of June 2026, GitHub Copilot uses a token-based billing system called "AI Credits." Every interaction with Copilot beyond basic code completions consumes tokens, which are charged against your monthly credit allocation. When your credits run out, you either stop using premium features or pay overage rates for additional consumption.
This replaces the previous system where you paid a flat monthly fee ($10-39/month) and received unlimited usage with soft throttling caps. The new system is more transparent — you can see exactly what each action costs — but also more unpredictable if you don't monitor usage.
How AI Credits Work
Each plan includes a monthly credit allocation:
| Plan | Monthly Fee | Included Credits | Overage |
|---|---|---|---|
| Pro | $10/month | $10 in AI Credits | Pay-as-you-go |
| Pro+ | $39/month | $39 in AI Credits | Pay-as-you-go |
| Enterprise | Custom | Pooled team credits | Negotiated |
Credits are consumed at different rates depending on which underlying model processes your request and how many tokens it uses. Using a frontier model (Claude Opus 4.8, GPT-5.5) costs 3-10x more credits per interaction than using a mid-tier model (GPT-4o, Claude Sonnet).
What Costs Credits (and What Doesn't)
Free (no credits consumed): Inline code completions, basic tab suggestions, and simple autocomplete. These remain unlimited on all plans.
Costs credits: Chat conversations, agent mode sessions, code explanations, test generation, multi-file edits, and any feature that involves extended model reasoning. Agent mode is the biggest consumer — a single multi-file refactoring session can use $2-15 in credits.
Estimating Your Monthly Bill
Here's a framework for estimating your monthly Copilot cost under token billing:
Step 1: Count your daily interactions. How many times per day do you use chat, agent mode, or code generation features? Typical ranges: light user (5-10 interactions/day), moderate (20-40), heavy (60+).
Step 2: Estimate tokens per interaction. A simple chat question uses ~2K input + 1K output tokens. An agent mode session uses ~20K-100K total tokens. Code explanation or review uses ~5K-15K total tokens.
Step 3: Multiply by model rates. GPT-4o: ~$0.01-0.03 per interaction. Claude Sonnet: ~$0.02-0.05. Claude Opus / GPT-5.5: ~$0.10-0.50 per interaction.
| Usage Level | Daily Interactions | Estimated Monthly |
|---|---|---|
| Light (mostly completions) | 5-10 chat/agent | $8-15 |
| Moderate (daily chat + agent) | 20-40 | $30-80 |
| Heavy (frequent agent mode) | 60+ | $150-500+ |
| Power user (all-day agent) | 100+ | $500-3,000+ |
How to Keep Costs Under Control
Set spending caps: GitHub's billing settings now include monthly spending limits. Set one immediately after the transition.
Choose models wisely: Default to cheaper models (GPT-4o) for routine tasks. Only switch to premium models for genuinely complex work.
Batch your agent sessions: Instead of 10 separate small agent requests, combine related tasks into a single focused session. You'll pay less in context setup costs.
Monitor weekly: Check your credit usage dashboard every Monday. Catch runaway costs early rather than at month-end billing.
Frequently Asked Questions
Do GitHub Copilot code completions cost money?
No. Inline code completions (tab suggestions) remain free and unlimited on all plans. Only chat conversations, agent mode sessions, and extended code generation features consume AI Credits.
What happens when I run out of AI Credits?
When your included credits are exhausted, you can either stop using premium features for the rest of the month or continue with pay-as-you-go overage billing. If you've set a spending cap, Copilot will disable premium features when the cap is reached.
Can I estimate my Copilot bill before it arrives?
Yes. GitHub provides a real-time usage dashboard showing credit consumption. Check it weekly. A rough formula: count your daily chat/agent interactions, multiply by $0.03-0.10 each (depending on model), multiply by working days in the month.
Is GitHub Copilot still worth it under token billing?
For light users who mostly rely on code completions, the $10/month Pro plan remains excellent value since completions are free. For heavy agent-mode users, compare your estimated monthly cost against alternatives like Claude Code ($20/month + API) or Cursor ($20-40/month) to find the best value.
