Frequently asked questions

How is 'estimated monthly cost' calculated?

It applies each model's own input/output pricing to the workload assumptions you enter above (monthly requests, average input tokens, average output tokens) — the same formula used across every calculator on this site.

What happens when I click 'Use this model'?

It opens the AI Budget Planner with that model pre-selected, so you can build out the rest of your budget — usage, RAG, and infrastructure — without re-entering the model choice.
