What is ChatGPT API Token Estimator?

This tool estimates the number of tokens your text will consume when sent to the ChatGPT API and calculates the approximate cost based on your per-1,000-token pricing. It’s helpful for budgeting API usage and avoiding unexpected charges. The estimator uses an average conversion of 1 token ≈ 4 characters (typical for GPT models).

How to Use:

1. Paste Your Text: Enter your prompt, user input, or AI-generated content in the text area.
2. Set Cost per 1,000 Tokens: Input the price your plan charges per 1,000 tokens.
3. Click “Estimate Tokens & Cost”: The calculator will analyze your text.
4. Review Results: You’ll see the number of characters, words, estimated tokens, words per token, and estimated cost.
