Assumptions & limits

Assumptions & limits

  • User-supplied volumes already grouped by retention policy; storage and access unit prices share one currency. No live cloud price assumptions, retrieval minima or transfer fees. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
Are these inputs private?

These calculations run in your browser. A shared link contains the values you choose to share. Only questions submitted to the separate AI finder are sent to OpenAI.
