How Gemini 2.5 Pro pricing works
Gemini 2.5 Pro is billed per token: a lower input price of $1.25 per million tokens for everything you send, and a higher output price of $10.00 per million for everything the model generates. To turn that into a real Gemini 2.5 Pro bill, multiply by your monthly request volume and average prompt/response length — the calculator above does exactly that.
Gemini 2.5 Pro does not list a separate cached-input rate, so every input token bills at $1.25 per million. If repeated context is a big part of your prompts, a model with prompt caching may end up cheaper in practice.
List prices move fast — always confirm the current numbers on the official Google pricing page before relying on them for budgeting.
