Tokens are the basic unit of text that OpenAI models process. This calculator helps you estimate token count from character count and calculate the exact API cost for your text.

Useful for developers building prompts, writers estimating API costs, and businesses planning AI budgets.

How Token Counting Works

  1. Enter your text size - Characters or estimate from word count
  2. Select language - Token density varies by language
  3. Choose token type - Input vs output have different pricing
  4. See costs - Compare GPT-4o vs GPT-4o Mini

Token Estimation Rules

  • English: ~4 characters per token
  • Russian/Cyrillic: ~2 characters per token
  • Chinese/Japanese: ~1.5 characters per token
  • Code: ~3 characters per token

Quick estimate: 1,000 words โ‰ˆ 1,333 tokens (English)

Pro Tips
