LLM Cost & RAG Calculator PRO · BROWSER ONLY
Plan token spend, semantic-cache economics, and RAG context limits before deployment. This calculator runs entirely in your browser—no login, API key, or user data storage.
Use your provider’s current token rates. The included profiles are editable example scenarios, not live pricing.

02 Cache assumptions

03 RAG context budget
Updates automatically as inputs change.
