Illustrative planning math only — vendor prices and tokenizers change. Nothing is uploaded to a server unless a mode explicitly calls a public API (none do here).
About Knowledge Base Size Calculator
Knowledge Base Size Calculator is used to estimate the token count, embedding cost, and vector storage requirements for a RAG knowledge base of a given size. It works by: it estimates the number of chunks, total tokens, and embedding API cost based on your document count, average document length, and chunk size settings. Smaller chunks (256-512 tokens) improve retrieval precision but increase chunk count and storage costs — larger chunks (1024+ tokens) reduce costs but may include irrelevant context in retrieved results. Knowledge Base Size Calculator runs free in your browser at abovetool.com — no signup required.
