Pick a model, describe your workload, and get one honest number — input, output, reasoning and caching included.
TokenCount estimates tokens and cost across the models teams actually ship with.
Every model ranked by total cost for the token mix above. Top 3 flagged — cheapest wins.
AITokenCalculator is a free AI token calculator that estimates how many tokens your prompt uses and what it costs across 51 models from nine providers — OpenAI GPT-4o and o-series, Anthropic Claude, Google Gemini, Mistral, Meta Llama, xAI Grok, DeepSeek, MiniMax and Moonshot Kimi. Paste text for an instant count, switch to the Chat tab to see multi-turn context growth, or open the Media tab for image and audio pricing. Everything runs in your browser.
Paste text or upload a file — tokens estimated from character density tuned per tokenizer (English ≈ 4 chars/token).
Compare input, output, cache and batch pricing side by side with verified rates.
Enter daily request volume to see a full month of projected cost with cache-hit savings.
Paste your text into AITokenCalculator, pick a model, and enter expected output tokens. The calculator estimates input tokens from character density and multiplies by the model's per-million-token price — including prompt-cache discounts and batch mode.
For English, one word ≈ 1.3 tokens (about 4 characters per token). Code runs ~2.5 characters per token; Chinese, Japanese and Korean can take 1.5 characters or fewer per token.
51 models across nine providers: OpenAI (GPT-4o, o-series), Anthropic Claude, Google Gemini, Mistral, Meta Llama, xAI Grok, DeepSeek, MiniMax and Moonshot Kimi — with pricing verified against official sources.
Yes. AITokenCalculator runs entirely in your browser — no signup, no API key, nothing sent to a server. Estimates only; always confirm final pricing with the provider.
Yes. The Media tab estimates image tokens using OpenAI's tiling math plus flat-rate models, audio cost per second, and combined multimodal workloads.
