AI Token Counter
Estimate how many AI tokens a pasted prompt may use and what it may cost based on configurable per-million-token prices.
Token estimate
26 estimated input tokens (0.33% of selected context).
- Words: 15
- Characters: 102
- Estimated prompt cost: $0.000130
- Estimated completion cost: $0.007500
- Total estimated cost: $0.007630

How to use this tool
Enter the required values in the labeled fields. Results update in your browser and are announced for assistive technologies. Use realistic measurements and verify important outcomes before acting on them.
Formula or logic
No external tokenizer or AI API is called. The generic fallback estimates tokens as characters divided by about 4, with model-specific estimate ratios.
Example calculation
Example: 4,000 characters are roughly 1,000 tokens with the generic estimate.
Frequently asked questions
Does this call an AI API?
No. It never sends text to an external AI service.
Are costs exact?
No. Costs depend on actual tokenizer, model pricing and provider billing rules.
