This free Gemini cost calculator shows your likely monthly bill. We could not confirm the price on the official page, so we show the same work on tools with confirmed prices. Your real cost depends on your own usage, so enter your numbers above. We use the official Gemini pricing page, last checked on November 3, 2026.
What is the Gemini API?
The Gemini API gives developers access to Google's Gemini models. It is known for fast, low-cost Flash models, strong handling of images, audio and video, and very long context. Google AI Studio is the browser workspace where you test prompts and create API keys; larger companies often use Gemini through Google Cloud instead.
Gemini also powers voice agents through its Live API, and many agent tools let you pick a Gemini model behind your agent.
How much does Gemini API cost?
Price not confirmed. When we last checked on 2026-11-03, Google's official Gemini pricing page redirected to a "Page Not Found" screen, so we do not show Gemini token prices yet. Check the official pricing page before you budget.
Like other model APIs, Gemini is pay per token: you pay for the text (and images, audio or video) the model reads and the text it writes. There is usually a free tier with rate limits for testing, and paid tiers for production use.
Gemini prices you can see inside other tools
Some tools in this calculator list their own rates for Gemini models, which gives a useful idea of the price range:
- GoHighLevel Conversation AI lists Gemini 3.8 Flash at $0.75 per million input tokens and $3.75 per million output tokens, and Gemini 3.5 Flash Lite at $0.30 and $2.50. Its Voice AI lists Gemini 3.8 Live at $0.10 per minute. See the GoHighLevel cost calculator.
- Retell AI lists Gemini 3.8 Flash at $0.048 per minute for voice agents and $0.015 per chat message. See the Retell AI cost calculator.
These are those tools' prices, not Google's direct API prices, and they can include each tool's margin. For comparison, the calculator's default model, GPT-6.1 Terra, costs $1.00 in and $5.00 out per million tokens directly from OpenAI.
What is included, and what is not?
- Included: model calls billed per token, Google AI Studio for testing.
- Not included: hosting for your agent code, Google Search grounding and other tools (often billed separately), Google Cloud services you add.
What hidden costs should you watch for?
- Free tier data use. Check whether data sent on a free tier may be used to improve Google's products before you send customer data.
- Long-context pricing. Many providers charge more per token for very long prompts; check Gemini's tiers.
- Media tokens. Images, audio and video count as tokens too.

How do you set up Gemini?
The steps below show the general setup. Button names change often, so follow the idea of each step rather than exact labels.
- Open Google AI Studio. Sign in with a Google account.
- Get an API key. Create a key and link a billing account for paid usage.
- Test prompts. Try your agent's instructions in AI Studio first.
- Build your agent. Call the Gemini API from your code or a tool that supports Gemini.
- Check the current price. Read the official pricing page before you estimate costs, since we could not confirm it.
Tips from setup
- Many tools in this calculator, like GoHighLevel and Retell, also offer Gemini models with their own listed rates.
How do you calculate your Gemini cost?
- What would Gemini do for you?. Pick the job closest to yours. We fill in typical usage for that job, so you do not need to know anything about tokens.
- How many times a day?. Use a normal working day. A rough guess is fine, and we count 22 working days a month.
- Read your answer. We could not confirm Gemini's prices, so you see the same work on tools with confirmed prices.

How should you budget for Gemini?
With a model API, you pay for what the model reads and writes, so your bill comes from your own design choices. The length of your instructions, how much chat history you resend, and how many steps each task takes matter as much as the price per token. Doubling the steps roughly doubles the cost.
To budget for Gemini, run 20 to 50 real tasks through the model and record the tokens each one uses. Multiply the average by your expected monthly volume, then add 20% for retries and long requests. Set a monthly spending limit in your account so a bug cannot run up a large bill. Remember the API price does not cover hosting, your own development time or any paid tools your agent calls.
