AI Video Cost Calculator
See what the same video costs on every major AI video model.
Prices are per second of generated video. Taxes, volume discounts and failed generations are not included.
How is AI video priced?
Most video APIs charge per second of generated video. Higher resolutions and native audio cost more, so a 1080p or 4K clip can cost far more than a 720p clip.
What is the cheapest AI video model?
It depends on the resolution. Light models such as Veo 3.1 Lite, Grok Imagine and Wan start around $0.05 per second, while premium models at 4K can cost $0.40 per second or more.
Is Sora included?
No. OpenAI removed the Sora 2 video models from its API on September 24, 2026, so Sora is no longer available to developers.
How to use the video cost calculator
- Enter the length of each clip in seconds and how many clips you need.
- Choose a resolution and whether you need generated audio.
- The list ranks every model that offers that combination by total cost, cheapest first.
How prices are calculated
Most video APIs charge per second of output, so the total is seconds × clips × price per second. Luma bills per 5- or 10-second clip instead, and longer videos are counted as several clips. Some models include audio in every clip; others charge more when audio is on. Where a model's maker publishes no per-second API price, we show Runway's API rate for it and label it.
Budget for retries
The calculator shows the cost of one generation. In practice a usable shot often takes two to four attempts, so multiply by about three for a realistic budget, and test prompts on a cheap draft model at 720p before rendering the final take.
