TokenMath.io
Know your AI API costs before you ship.
Estimate AI API costs, token usage, and monthly budgets for OpenAI, Gemini, Claude, embeddings, images, audio, and vector storage.
Hi Product Hunt! 👋 I'm Anthony.
If you are building an AI wrapper, a RAG application, or integrating LLMs into your backend, you already know the pain of predicting costs. Staring at OpenAI, Anthropic, or Gemini pricing pages trying to manually calculate a mix of input tokens, output tokens, and vector database storage is a nightmare.
I built TokenMath.io to solve this. It is a suite of 11 fast, transparent calculators designed to help you plan your full AI stack costs before you ship.
What's inside:
LLM Token Estimators: Compare projections across top frontier models.
Infrastructure Planners: Estimate Vector Database storage and Embedding generation costs.
Media Calculators: Project costs for Image Generation and Audio Transcription.
The Engineering Focus:
I built this with a strict focus on speed, privacy, and a zero-latency UI. Every calculator provides transparent math (showing you the exact formulas behind the estimates) and versioned pricing so you always know exactly when the API pricing was last verified.
I would love to hear what models or specific infrastructure calculators you want to see added next. I'll be hanging out in the comments all day to answer questions!
