AI Video Cost Calculator
Compare what a month of AI video generation really costs across the major tools, and see which ones watermark your output or make you subscribe first. Costs shown for the other tools are their entry monthly plan, the realistic price at real volume. Sisif has no subscription: $1 a clip, and it never watermarks an export.
| Tool | Est. cost / month | No watermark without a subscription | How you start |
|---|---|---|---|
| Sisif | $30 | $1 a clip | |
| Kling | from $5.99/mo | ~66 credits/day | |
| Pika | from $8/mo | ~80 credits/month, 480p | |
| Hailuo | from $9.99/mo | ~3/day + 200 bonus | |
| PixVerse | from $10/mo | 30 credits/day + 60 on signup | |
| Runway Gen-4 | from $12/mo | 125 one-time credits | |
| Sora | from $20/mo | none (via ChatGPT Plus) | |
| Luma Dream Machine | from $30/mo | 30 generations/month |
Cost shown for the other tools is their entry monthly plan, because at real volume you pay a plan and not a linear per-second rate. Sisif is priced per clip instead: $1 a clip, paid once. Its row switches to a monthly credit plan ($10 for 100 credits, $50 for 1000, $200 for 5000) only when that plan costs less than paying per clip at your volume, where a clip costs 2.5 credits per second.

Which AI video generators export without a watermark?
Among major tools only Sisif exports without a watermark on every plan, including a single $1 clip. Pika, PixVerse, Runway, Sora, Kling, Luma and Hailuo all watermark output until you buy a plan that removes it: Pika from $28/mo, PixVerse from $10/mo.
What is the cheapest AI video generator?
On entry pricing Kling (~$6/month) and Pika ($8/month) are the cheapest subscriptions, then Hailuo and PixVerse near $10; Runway, Sora and Luma cost more. Sisif asks for no subscription at all: $1 a clip, so three clips a month costs $3, under every entry plan on this list.
