A rate per million tokens is not a budget. The calculator takes your request volume, prompt size and cache hit rate and gives you a monthly figure.
Gemini 2.5 Pro API pricing (October 2026)
Prompts above 200K tokens bill at $2.50 in / $15 out. Context caching adds storage at $4.50 per 1M tokens per hour, not modeled here.
What it costs at real volumes
A chat-shaped workload: 800 input tokens and 300 output tokens per request, no caching, no batch.

Frequently asked questions
How much does Gemini 2.5 Pro cost per 1M tokens?
Gemini 2.5 Pro costs $1.25 per million input tokens and $10.00 per million output tokens at Google Gemini list prices. Output is 8.0x the input rate, so the input:output ratio of a workload drives the real cost more than the headline price.
Does Gemini 2.5 Pro support prompt caching?
Yes. Cached input is billed at $0.125 per million tokens, 10x cheaper than uncached input. There is no cache-write premium, but storage is extra: Google charges $4.50 per 1M tokens per hour to keep a cache, which these figures leave out.
What is the batch discount for Gemini 2.5 Pro?
Requests submitted through the asynchronous batch endpoint are billed at 50% off both input and output rates, bringing input to $0.625 and output to $5.00 per million tokens.
What is Gemini 2.5 Pro's context window?
1.0M tokens of context with up to 66K output tokens per request. A larger context window raises the ceiling on what you can send, not the price per token, but filling it on every request is one of the most common causes of an unexpected bill.
