RAG Pipeline LLM API Cost Estimator
Estimate monthly LLM costs for a Retrieval-Augmented Generation (RAG) pipeline. RAG pipelines have higher input token counts due to retrieved context.

Frequently Asked Questions
Why are RAG pipeline token costs higher than regular chatbots?
RAG injects retrieved document chunks into every prompt. Each retrieval adds 500–2,000 tokens of context. A moderate RAG system serving 5,000 queries/day can consume 100–500M input tokens per month.
Which LLM is best for RAG pipelines?
Claude Haiku 4.5 ($1/1M input) and GPT-4.1 Nano ($0.10/1M) are popular choices. For RAG with very long context windows, Gemini 2.5 Flash ($0.30/1M) supports 1M tokens per request and has excellent price/performance.
Should I self-host the LLM for my RAG pipeline?
If your RAG pipeline consumes 500M+ tokens/month, a self-hosted A100 or two RTX 4090s may become cost-competitive. Use this calculator to find your break-even point.
