How to Use
- Enter your input text to estimate token count
- Tool uses ~4 characters per token estimation (standard)
- Select LLM model to see pricing estimates
- Compare costs across different AI platforms
- Calculate total API costs for your requests
- Plan budget for large-scale API usage
Characters: 0
Pricing prices per 1M tokens
Token Estimation Method
This tool uses the standard rule of thumb: 1 token ≈ 4 characters
- Estimation: Length / 4 (rounded up)
- Actual token count varies by model and tokenizer
- GPT models use BPE encoding (Byte Pair Encoding)
- Claude uses SentencePiece tokenizer
- Use
tiktokenlibrary for exact counts

Frequently Asked Questions about Token Count & Cost Estimator
We use a tokenizer compatible with OpenAI's models (like cl100k_base) to provide a highly accurate estimate of token usage.
