Google Flow Credits Calculator: Veo 3.1 & Omni Flash
Google Flow charges credits per generated video, and the cost depends on the model, the resolution, the clip length, and whether you are on Google AI Ultra. Pick a plan and a model below to see credits per clip, clips per month, and the effective dollars per second. On Google AI Pro ($19.99 a month, 1,000 Flow credits), an 8-second Veo 3.1 Lite clip costs 10 credits. That is 100 clips a month, or about $0.025 per second of video.
Last updated 2026-11-11. Flow numbers checked 2026-11-11 on Google Flow Help and the Google AI plans page. API prices last checked 2026-11-11.
Assumptions: the $/s figure is the plan's monthly price divided by its monthly Flow credits, times the credits a clip uses, divided by the clip length. It assumes you use every credit and puts the whole plan price on video, although Google AI plans include other benefits. The 50 free daily credits are left out unless you tick the box. Prices are US prices from Google's plans page. Taxes and student or trial offers are not included.

Omni Flash 1.2 at 720p on Google AI Pro works out to about $0.06/s for a 10-second clip, next to $0.07/s for gemini-omni-1.2-flash on Google Gemini API (720p, estimated rate, checked 2026-11-11). Veo 3.1 Lite on Google AI Pro is about $0.025/s for an 8-second clip. The cheapest current Veo 3.1 API row we track is $0.10/s for veo3.1_fast (no audio) on Runway API (resolution not listed, published rate, checked 2026-11-11). That is a different Veo 3.1 mode, so treat it as a price reference, not a like-for-like match. Our Gemini API Veo 3.1 rows are marked discontinued, so they are not in this table. They stay on the Veo 3.1 page under retired prices.
Separate from Flow, on the Gemini API: Effective December 3, 2026, requests to gemini-omni-1.1-flash route to gemini-omni-1.2-flash and are billed at 1.2 rates. (from our Gemini Omni Flash price rows, source, checked 2026-11-11).

Gotchas Google states
- Credits are per video, not per prompt. “The Google Flow/AI credit costs below are per generation, not per request. Some product features will create multiple generations per request. For example, in Google Flow, you can make a single request that may generate 2 videos.”
- Monthly credits do not roll over. “Google Flow credits for your Google AI Plus, Pro, or Ultra plan refresh at the start of your billing cycle. Unused monthly Google Flow credits do not roll over to the next month.”
- The 50 daily credits refresh from your first generation. “Your daily credit refresh is triggered by your first generation. For example, if you use your Google Flow credits for the first time on August 12, your next 50 Google Flow credits will become available on August 13. If you don’t use the full 50 Google Flow credits in a day, the unused Google Flow credits don’t roll over.”
- No plan, no video at peak times. “During peak hours, roughly 2 PM to 5 PM UTC, you may not be able to generate videos without a subscription.”
- Veo Extend is gone. “On November 5, 2026, Veo Extend was retired. To extend a video, you must be a Google AI Plus, Pro, or Ultra subscriber and use Omni Flash 1.2.”
- Costs can change. “Limits are subject to change at any time. To find the latest costs, at the top right of your prompt box, click Settings.”
- Veo 3.1 Lite can cost 0 credits on Ultra 20x. Google's table lists 0 credits for 4s, 6s, or 8s Veo 3.1 Lite videos in Lower Priority mode, for Ultra 20x subscribers & family plan managers only. The calculator does not price that mode, because a zero-credit video has no per-credit cost.
Quotes from Manage your Google Flow credits (Google Flow Help), checked 2026-11-11. Peak hours of 2 PM to 5 PM UTC are 6 AM to 9 AM Pacific while the US is on standard time.
How many Veo 3.1 videos does Google AI Pro get in Flow?
Google AI Pro adds 1,000 Flow credits a month. Veo 3.1 Lite costs 10 credits per video at 4, 6, or 8 seconds, so that is 100 Veo 3.1 Lite videos a month. Veo 3.1 Fast costs 20 credits, so 50 videos, until it retires on 2026-12-05. Everyone also gets 50 credits a day, and a request that makes 2 videos uses credits for both.
Do Google Flow credits roll over?
No. Google says unused monthly Flow credits do not roll over to the next month, and unused daily credits do not roll over either. Monthly plan credits refresh at the start of your billing cycle.
When do the daily Flow credits refresh?
Google says the 50-credit daily refresh is triggered by your first generation, so the next 50 arrive the day after you first use them.
Why did one prompt use double the credits?
Google's credit costs are per generation, not per request. Google says a single Flow request may generate 2 videos, and each one is charged.
Is Google Flow cheaper than the API?
Omni Flash 1.2 at 720p on Google AI Pro works out to about $0.06/s for a 10-second clip, next to $0.07/s for gemini-omni-1.2-flash on Google Gemini API (720p, estimated rate, checked 2026-11-11). Veo 3.1 Lite on Google AI Pro is about $0.025/s for an 8-second clip. The cheapest current Veo 3.1 API row we track is $0.10/s for veo3.1_fast (no audio) on Runway API (resolution not listed, published rate, checked 2026-11-11). That is a different Veo 3.1 mode, so treat it as a price reference, not a like-for-like match. The Flow figure assumes you use every credit and counts the whole plan price as video spend.
What changes in Flow on 2026-12-05?
Google says Veo 3.1 Fast, Veo 3.1 Quality, and Omni Flash 1.1 will be retired on 2026-12-05, and points users to Omni Flash 1.2 or Veo 3.1 Lite. The calculator drops those models after that date.
Can I buy more Flow credits?
Google says Plus, Pro, and Ultra plan members can buy AI credits in supported regions, except Japan. Google's help page does not list AI credit prices, so they are not in this calculator.
How is this different from the VidFare credit calculator?
This page only covers Google Flow credits on Google AI plans. The credit calculator (https://vidfare.com/calculator/) covers Higgsfield, Krea, and Magnific plans, and the project budget calculator (https://vidfare.com/guides/ai-video-project-budget/) prices a finished video from dollars per second.
How do we calculate this?
Plan prices and monthly Flow credits come from Google's plans page. Credits per video come from Google Flow Help. Dollars per second is plan price ÷ monthly Flow credits × credits per video ÷ clip seconds. It assumes every credit is used and the whole plan price is spent on video, so it is an estimate, not a list price. API rates are the current API rows in VidFare's price data, each with its own source and checked date. The daily price check re-reads every Flow number on Google's pages.
