What is GPT Words Per Token Calculator?

The GPT Words Per Token Calculator is a tool designed to help you understand the relationship between words and tokens in AI-generated or user-provided text. Tokens are the units used by GPT models to process text, and knowing words-per-token helps you estimate token usage, optimize prompts, and manage API costs. The calculator can either estimate tokens from the text using a simple heuristic (1 token ≈ 4 characters) or use an actual token count if provided. It then calculates words per token and tokens per word, giving insight into your text’s token efficiency.

How to Use:

1. Paste or Type Text (Optional): Enter your text to analyze word and character counts.
2. Enter Actual Token Count (Optional): If you know the token count from your AI system, input it to get an exact words-per-token ratio.
3. Click “Calculate”: The calculator will compute words, characters, token count (estimated or actual), words per token, and tokens per word.
4. Review Results: Use this information to estimate prompt costs, adjust text length, or optimize token usage in AI projects.
