Gemini calculator

Start with text. Expand only when Gemini pricing needs it.

Estimate Gemini API cost from usage tokens or planning text. Modality, context caching, and grounding stay tucked into one advanced section so the first estimate stays fast.

Inputs
Numeric workload is saved locally in this browser for easier comparison. Prompt text is not saved.
Gemini options: audio, cache, grounding

Leave these off for simple text chat. Open them for multimodal input, cached context, or Google Search grounding. For image, audio, video, PDF, tools, and system instructions, use Gemini Count Tokens for exact request counts.

High confidence: based on Gemini usage metadata or Count Tokens API numbers.

Pricing checked 2026-05-09. Gemini 3 Flash Preview: input $0.5/1M, output $3/1M tokens. Output pricing includes thinking tokens when listed by Google.

Cost insight: the largest cost driver is output tokens. Cutting output tokens by 50% would save about $18.00 per month.

Estimated planning result only. Prices can change, and provider bills may include taxes, minimums, feature-specific charges, or usage adjustments. Verify production spend in the official provider dashboard.

How to use

How to use this calculator

  1. Start simple

    Use text token inputs first. Open modality, cache, or grounding options only when your Gemini request needs them.

  2. Add advanced usage

    Include cached context, audio modality, or grounding requests when those features are part of the workload.

  3. Compare the result

    Copy the estimate or compare with OpenAI, Claude, or DeepSeek to understand the budget tradeoff.

Gemini cost guide

Keep text simple, then add Gemini-specific features only when needed.

Gemini pricing can change with modality, context caching, grounding, and context length bands. The calculator keeps the first estimate fast while still exposing the cost drivers that matter.

How the estimate works
Input and output

Text prompts and generated answers are estimated from token counts and the selected Gemini model's prices.

Modality and context

Audio, video, images, large context, and cached context can change the estimate, so advanced options stay grouped instead of hidden.

Grounding and batch

Grounding requests and Batch mode are separate adjustments because they describe different production behavior.

Example workloads
Text chat

Start with normal prompt and response tokens for a clean Gemini Pro or Flash comparison.

Multimodal review

Use advanced modality settings when the workload includes audio, video, images, or PDFs rather than plain text.

Grounded answer

Add grounding only for requests that actually need Google-backed retrieval or citation behavior.

Cost optimization tips
  • Begin with text-only estimates, then add modality costs after the baseline feels reasonable.
  • Use Gemini Count Tokens for media, tools, and system instructions because text heuristics can drift.
  • Turn on grounding only for flows that need it; not every chat answer should pay that premium.
  • Watch context-length thresholds when prompts grow because long-context pricing can change the result.
Common mistakes
  • Using a text-only token estimate for media-heavy requests.
  • Assuming grounding is included in every model token price.
  • Forgetting cached context when repeated documents are part of the request.
  • Ignoring thinking or extra generated tokens in complex answer flows.

Gemini API pricing Gemini token guide Gemini Count Tokens API Gemini context caching

Google's Count Tokens API can count request-like content including text, chat, inline media, video, PDF, cache, system instructions, and tools. This static page does not ask for an API key or call Google APIs.

Image generation, Veo/video generation, Vertex enterprise pricing, and exact media dimension or duration estimators are intentionally excluded from this first Gemini calculator.

FAQ

Gemini API cost quick answers

What does the Gemini API cost calculator estimate?

It estimates input and output token cost, Batch pricing where available, context caching, grounding requests, and projected daily, monthly, and annual spend.

Why does Gemini pricing include modality options?

Gemini models can price text, image, video, and audio inputs differently, so the calculator keeps modality visible without making the default workflow complicated.

Is Gemini Count Tokens required to use this page?

No. This page gives private planning estimates in the browser. Use Gemini Count Tokens for exact request-like counts before committing a production budget.
