How to Use AI Token + Pricing Calculator

  1. 1

    Paste text and count tokens across multiple LLMs

    Paste your prompt or response text. The calculator counts tokens for GPT, Claude, Gemini, Llama, and more so you can compare token efficiency for your use case.

  2. 2

    Calculate API cost for your prompts

    Paste prompt + expected response. The calculator counts tokens and multiplies by current model rates so you can estimate cost before deploying and keep API spend predictable.

  3. 3

    Compare LLM costs across API providers

    Run the same prompt across multiple models. The calculator shows costs side-by-side across providers so you can optimize for the right price/performance trade-off.

  4. 4

    Estimate batch job costs before running

    If processing 10,000 documents with summarization, calculator estimates total cost across models. Batch of 10k * 1000 tokens average = 10M tokens. At $0.01/1M = $100. Know budget before committing.

  5. 5

    Monitor and alert on token overages

    Track costs of recent API calls. If one call cost 10x more than expected (verbose output?), calculator highlights anomaly. Helps catch infinite loops or huge responses wasting budget.

Frequently Asked Questions

What is the AI Token + Pricing Calculator?
It's a free tool that lets you paste text, instantly count tokens across different LLM tokenizers (GPT, Claude, Gemini, Llama, Mistral), and see what that text would cost as input or output across every major AI provider — all in one view.
How do I use the AI Token + Pricing Calculator?
Paste or type your text in the input area. The tool instantly shows token counts per tokenizer family and a cost comparison table across all models. Switch to Batch Estimate mode to project costs for thousands of requests. Export results as CSV or Markdown.
Is this tool free?
Yes. Free to use with immediate access—no account required. All calculations happen in your browser — no API calls, no rate limits.
Does this tool store or send my text?
No. All processing happens entirely in your browser. Your text never leaves your device — nothing is sent to any server.
Which LLM is cheapest for my use case?
Paste a representative text sample and check the cost comparison table sorted by Total cost. For batch workloads, use the Batch Estimate tab to project monthly costs. The cheapest model is automatically highlighted.

Quick Cost Estimates

A typical 1,000-word document is roughly 750 tokens (GPT-family tokenizer) or ~850 tokens (Claude-family tokenizer). Cost depends on provider, model tier, and output length:

  • Flagship reasoning/coding models usually have the highest output-token costs.
  • Balanced mid-tier models are often the best quality-to-cost trade-off for production apps.
  • Fast and budget variants can be dramatically cheaper for high-volume pipelines.
  • Open-weight and budget providers are often best for bulk summarization and classification.
  • The table above is the source of truth for current per-model rates and families.

Prompt caching can reduce input costs by 75-90% for repeated prefixes. All Anthropic, OpenAI, and Google models support caching.
