About the Token Usage Calculator
LLMs measure text in tokens, not words, and cost scales with token count. This free token counter counts the exact number of GPT tokens in your text using a real tokenizer, and estimates the cost for any model — so you can size prompts and budgets precisely.
Counting happens in your browser; your text isn't uploaded.
How to count tokens
- Paste your text.
- See the exact token count from a real GPT tokenizer.
- Estimate the cost for your chosen model.
Why token counts matter
Language models bill per token, not per word, and a token is roughly four characters or three-quarters of an English word. Long prompts, big system messages and verbose outputs all add up — and a prompt you send on every request multiplies fast at scale. Counting tokens before you ship lets you size context windows and estimate cost accurately instead of guessing.
Frequently asked questions
What is a token?
A token is a chunk of text — roughly 4 characters or three-quarters of a word in English — that language models use as their unit of input and output, and of billing.
How many tokens is a word?
On average about 1.3 tokens per English word, but it varies with punctuation, spacing and language. This tool counts exactly rather than estimating.
Is my text private?
Yes. Tokenization runs locally in your browser and your text is never uploaded.
