Rough Approx converter for English budgeting, not Exact tokenization. For OpenAI Exact counts, use the tokenizer.

Tokens ↔ words FAQ

Is this Exact tokenization?
No. This page uses a rough English heuristic (~4 characters per token, ~0.75 words per token). For Exact OpenAI encodings, use the tokenizer.
Why do code and other languages differ?
Code, URLs, and non-English text often use more tokens per word or character. Treat these numbers as budgeting shortcuts, then verify with Exact counts or provider tools.
Should I use this for API billing?
Use it for ballpark planning only. Billing follows each provider’s tokenizer. Open TokenCALC’s main tokenizer/cost calculator for model-specific Exact or Approx counts.
