How many tokens is your text — and what those tokens cost per month.
Every LLM meters tokens, and the word-to-token ratio quietly inflates code and non-English text. Convert token counts to a real bill on the LLM token cost calculator, and check they fit the model window on the context window calculator.
Free words-to-tokens calculator — estimate the token count of any text and the monthly API cost from your word count and per-million price.
As a rule of thumb, one English word is about 1.33 tokens, and 100 tokens is roughly 75 words. Put differently, four characters is about one token. It is only an average — punctuation, numbers, code and non-English scripts split into more tokens per word.
Because APIs bill per token, not per word or per request. Your monthly spend is total tokens (input plus output, across every call) times the per-million price. A small per-request text becomes a large bill once you multiply by traffic, so estimating tokens up front is how you size the budget.
