AI Coding Tool Cost Calculator
Every comparison site shows the $20 sticker price. We built the calculator that shows what you'll actually spend — based on how you code. Cursor Pro can reach $400/mo. Devin can reach $2,250/mo. See your real number.
Agentic = Composer, code refactoring, build full features. Non-agentic = autocomplete, tab suggestions.
Estimated Monthly Cost
Based on 4 hrs/day, 30% agentic, mixed complexity
How we calculate this
- Agentic tasks consume 1,000x more tokens than autocomplete
- Complex refactoring sessions: 500K–3.5M tokens each
- Conversation context multiplies — turn 50 costs 40x more tokens than turn 1
- ~70% of agent tokens are waste (retries, self-correction, redundant context)
- Cursor on-demand: enabled by default on newer accounts — check your settings
The Token Math Behind These Numbers
1,000x
More tokens — agentic vs autocomplete
A tab completion = ~50 tokens. One agentic refactoring session = 50,000–3,500,000 tokens. Using Composer for 30% of your coding time doesn't cost 30% more — it can cost 50-100x more.
70%
Token waste in agentic workflows
Developer analysis of 42 agent runs found 70% of tokens were waste — retries, self-correction loops, redundant context repetition. Efficient prompt patterns cut this significantly.
40x
Context cost multiplication by turn 50
Each API call includes full conversation history. At turn 50, what started as 5K tokens/call can hit 200K tokens/call — for the same output. Long agent sessions compound exponentially.

Average tools per developer (2026)
Developers don't use one tool — they stack them. IDE tool (Cursor/Claude Code) + browser builder (Bolt/Lovable) + completions (Copilot) = $150-400/mo total in active development periods.
