- Input cost at this model(GPT-4o)
- $0.0000
Paste text to estimate how many tokens it uses and what it would cost as input. Token counts vary by model and content type, so pick the closest option for a quick, reliable estimate before you send a prompt.
How this is calculated
This calculator uses the tokens formulas described in our methodology. All figures are estimates for planning; verify current pricing with each provider before relying on them.

Frequently asked questions
How accurate is this token counter?+
It uses well-established character-to-token ratios and is accurate to within a few percent for typical text. Exact counts vary slightly by each model's tokenizer.
Why do token counts differ between models?+
Each model family uses its own tokenizer, so the same text can map to slightly different token counts across OpenAI, Claude and Gemini.
