Kling 4.0 on Runway, Luma and Pika: what one minute costs
How this page is made. Every price comes from the vendor’s own pricing page, read on the date above. We have not compared the quality of the videos, so this page is about cost only. Some links are affiliate links; see the disclosure.
the short answer
Luma Ultra has the lowest price per second at $0.16. The Runway API needs no subscription and costs $0.24 per second. The most expensive plan here costs 3.6 times as much for the same model.
Kling 4.0 is sold on more than one platform, and the same model does not cost the same everywhere. Runway and Pika price it per five-second clip. Luma prices it per second. Once you turn all of that into dollars per second, the gap is large.
one minute of finished video, one take
This table is the cost to generate 60 seconds of Kling 4.0 at 1080p with no retakes. Credits are bought in whole months, so a small plan can take several months of credits to cover one minute.

what the numbers say
- Lowest price per second: Luma Ultra at $0.16. That plan is the most expensive monthly commitment on the list, so it only pays off if you use the credits.
- No subscription: the Runway API charges $0.24 per second, so a minute costs $14.10 with nothing to cancel. You need to be comfortable with an API project, not just an app.
- Cheapest single month: Runway API pay as you go covers the whole minute for $14.10.
retakes change the answer
Almost nobody keeps the first generation. If you need three attempts per clip, the credits you need triple. Use the calculator below and change takes per clip to see where each plan runs out.

what we left out
- Runway has a 25% off Kling 4.0 promotion until 30 November 2026. We use list prices so the page stays true after the promotion ends.
- We did not compare how the video looks on each platform. The model is the same, but each platform’s limits, queues and editing tools differ.
- Kling’s own pricing page would not load for us on 2026-11-13, so it is not in this comparison.
