Why this isn't trivial
The part people underestimate: Gemini's large context windows tempt big prompts, and since you pay per token, filling that window drives cost. In practice the biggest savings come from using RAG instead of stuffing the whole context window, so it is worth modelling before you commit.
How it's calculated
We estimate this by applying Gemini's per-model rates to your token sizes and monthly volume. Every figure uses the current provider prices baked into the site (reviewed daily), and you can override any input to match your own assumptions.
Frequently asked questions
Is Gemini's big context free?+
No — you pay per token used, so a large window is only cheap if you don't fill it.
Which Gemini tier is cheapest?+
The Flash tiers per token; reserve Pro for harder tasks.
Are these prices up to date?+
Yes. The model prices behind this calculator are refreshed and reviewed daily, so your estimate reflects current provider rates rather than a stale snapshot.
