AI Token Cost Calculator GPT · Claude · Gemini · more

📊 input + output ⚡ real‑time cost 🔁 10+ models 🎯 ai token cost calculator (500–1.2k/mo)

📖 Detailed introduction

Understanding AI API costs is critical when building with large language models. This AI Token Cost Calculator gives you a transparent, side‑by‑side comparison of the most popular models — GPT‑4o, GPT‑4 Turbo, GPT‑3.5 Turbo, Claude 3.5 Sonnet, Claude 3 Opus, Claude 3 Haiku, Gemini 1.5 Pro, Gemini 1.5 Flash, Llama 3 (70B), Mixtral 8x7B, and Command R.

Simply enter your estimated input tokens (prompt) and output tokens (completion), then choose a model. The calculator instantly shows the total API cost along with a breakdown of input and output costs. Perfect for budgeting AI features, RAG pipelines, agent workloads, or fine‑tuning experiments.

💡 Prices are based on public API rates (USD per 1 million tokens) — always check provider docs for the latest updates.

🧭 How to use (step by step)

  • 1. Set input tokens — enter the number of tokens in your prompt (e.g., 1000).
  • 2. Set output tokens — enter the estimated completion length (e.g., 500).
  • 3. Pick a model — click on any model card (GPT, Claude, Gemini, etc.).
  • 4. Calculate — press the “Calculate cost” button or just change any value (auto‑update).
  • 5. Read the breakdown — see input cost, output cost, and total API cost instantly.

🔄 The results update automatically when you change tokens or switch models. Use the compare feature to evaluate different models for your workload.

👥 Who should use it: AI engineers, product managers, researchers, and anyone planning LLM‑based applications.
