Veo 3.1 Cost Calculator

What it is

Veo 3.1 Cost Calculator is a free online tool that helps creators, agencies, and developers estimate their spending on Google's Veo 3.1 video generation API. Users can input their model tier (Standard, Fast, or Lite), resolution (720p, 1080p, or 4K), clip length in seconds, number of final clips needed, and expected retry waste percentage to get an accurate project budget.

The calculator reflects the per-second billing model used by Veo 3.1 on the Gemini API, where each retry adds the full cost of another generation rather than a fixed per-video fee. It displays rates for all tier and resolution combinations and shows how costs multiply with retries, helping users move beyond best-case single-pass estimates to realistic production budgets.

Questions from the bench

How much does Veo 3.1 cost per second?

On the Gemini API with audio, Veo 3.1 Standard costs $0.40 per second at 720p or 1080p and $0.60 at 4K. Fast costs $0.10/s (720p), $0.12/s (1080p), and $0.30/s (4K). Lite costs $0.05/s (720p) and $0.08/s (1080p) and does not support 4K.

Is Veo 3.1 free?

No. Google's published Gemini API pricing lists no free tier for Veo 3.1 video generation. Every billed output second counts toward your API bill, though consumer apps or trial credits may differ from the paid API which is per-second.

How do retries affect my Veo API bill?

Veo bills per output second generated, so each retry adds another full clip cost. Three takes of an 8-second Fast 1080p clip cost roughly $2.88 instead of $0.96.

Which Veo 3.1 tier should I use?

Use Fast or Lite for drafts and iteration, then switch to Standard for final shots. Most of a real budget goes to retries, so cheap tiers for exploration usually save the most money.

Does Veo 3.1 Lite support 4K?

No. Lite supports 720p ($0.05/s) and 1080p ($0.08/s) only. For 4K you need Fast ($0.30/s) or Standard ($0.60/s).
