Enter what a vendor is charging you per month plus how many AI queries you actually run. The tool back-calculates the underlying OpenAI / Anthropic / Google API cost, shows the markup multiplier the vendor is taking, and gives you a fair-price band to negotiate against. Browser-only. No data leaves your machine.

Token assumption: queries split roughly 60% input / 40% output. Add 15% for RAG embeddings overhead when you pick the RAG complexity tier.
