The AI Coding Assistant Landscape
AI coding assistants have become essential tools for engineering teams. But comparing them by sticker price alone misses the full picture. Here's a TCO analysis of the three most popular options.
Sticker Price Comparison
| Tool | Pricing | Per-Seat/Month | |---|---|---| | GitHub Copilot | Individual: $10/mo, Business: $19/mo, Enterprise: $39/mo | $10-$39 | | Cursor | Free tier, Pro: $20/mo, Business: $40/mo | $0-$40 | | Claude Code | API-based (pay per token) + Max plan: $100-$200/mo | $20-$200+ |
Hidden Costs Beyond the Subscription
API Overage Costs
Cursor and Claude Code can incur significant API costs when using your own keys:
- Heavy usage of Claude 3.5 Sonnet: ~$15-50/day per developer
- GPT-4o via Cursor's API: ~$5-20/day per developer
Productivity Variability
Not all tools are equal in productivity gains:
- Copilot: Best for inline completions, works in every IDE, predictable cost
- Cursor: Best for multi-file refactors, integrated chat, but may require model switching
- Claude Code: Best for complex reasoning and large codebases, but cost scales with usage
Context Window Costs
Larger context windows mean higher costs:
- Copilot: Fixed cost regardless of context
- Cursor: Varies by model chosen (GPT-4o vs. Claude vs. custom)
- Claude Code: Directly proportional to codebase size and prompt complexity
Team Overlap
The biggest hidden cost: teams using all three simultaneously.
- Developer A uses Copilot for autocomplete
- Developer B uses Cursor for refactors
- Developer C uses Claude Code for architecture
That's $70+/month per developer for overlapping functionality.
ROI Framework
To calculate true ROI, measure:
- Time saved per task — How much faster are code reviews, bug fixes, and feature work?
- Quality improvement — Fewer bugs, better test coverage, more consistent code?
- Adoption rate — What percentage of the team actually uses it daily?
- Cost per productive hour — Total cost / hours of developer productivity gained
Recommendations by Team Size
Small Teams (1-10)
Start with Cursor Pro ($20/mo). Best balance of features and cost. Add Copilot if you need broader IDE support.
Medium Teams (10-50)
Copilot Business ($19/mo) for everyone + Cursor Pro for power users. Standardize on one primary tool.
Large Teams (50+)
Copilot Enterprise ($39/mo) for organization-wide deployment. Evaluate Cursor Business for specialized teams. Avoid letting everyone choose their own tool.
