Token estimates: 1 English word ≈ 1.3 tokens. Actual tokenisation varies by model. Prices from official vendor pages as of April 2026. All calculations run in your browser — your data never leaves this page.
Route queries to different models by complexity
Production systems route simple queries to cheap models and complex ones to powerful models. Set your split to see the blended cost.
How much does one conversation cost?
Model a real conversation — set average turns and message length to see the cost across all providers.
Frequently Asked Questions
1. How does the token counter work?
Paste any text and the tool estimates tokens using the rule of thumb that 1 English word equals approximately 1.3 tokens. Actual tokenisation varies by model, but this gives a reliable planning estimate.
2. Which AI providers are included?
OpenAI (GPT-4o, GPT-4o mini, GPT-5, o3, o4-mini), Anthropic (Claude Sonnet 4.6, Haiku 4.5, Opus 4.6), Google (Gemini 2.5 Pro, 2.5 Flash, 2.0 Flash), DeepSeek (V3, R1), Azure OpenAI (GPT-4o, GPT-4o mini), and Mistral (Large, Small).
3. How accurate are the cost estimates?
Prices are sourced from official vendor pricing pages as of April 2026. The estimates use your specified usage profile (queries per day, token lengths) to project monthly and annual costs. Actual costs depend on your exact tokenisation and billing tier.
4. What are the use case presets?
Quick shortcuts that set realistic usage profiles for common scenarios: Chatbot (500 queries/day), Content Writer (50/day with long outputs), Data Analyst (200/day with long inputs), Search/RAG (1,000/day), and Agent Loops (100/day with 5x multi-turn multiplier).
5. What is the multi-turn multiplier?
AI agents often make multiple API calls per user interaction — a reasoning agent might call the API 5 times to answer one question. The multiplier accounts for this, giving you a more realistic cost estimate for agentic use cases.
