Kling's API ranges from $0.056 to $0.42 per second. The floor is Avatar at 720p — $0.448 for an 8-second clip. The ceiling is any of the five 4K Kling 3.0 rows — $3.36 for 8 seconds. The number most projects start from, Kling 3.0 at 1080p without native audio, is $0.112 per second, or $0.896 for 8 seconds.
Kling publishes 27 rows across 720p, 1080p and 4K, covering general video, avatar, motion-control and e-commerce models.
How Kling bills
Kling quotes models in Units and one Unit is $0.14, so a row at 1.2 Units bills $0.168 per second. Everything is per second of output, which makes Kling directly comparable to Runway and Sora and not comparable to Hailuo or Veo, which sell fixed clips.
The Credits per unit column below is Units, not dollars. Multiply by $0.14 to get the per-second price.

The 1080p step is cheap — 18% to 33% more than 720p. The 4K step is not: it multiplies the 1080p rate by 2.5× to 3.75×.
Audio is a 50% line item at 720p and 1080p, and free at 4K
Kling 3.0 without native audio is $0.112/s at 1080p; with native audio it is $0.168/s, 50% more. At 720p the same 50% gap applies: $0.084/s versus $0.126/s. At 4K both rows list $0.42/s, so the audio flag does not change the price there.
Turbo flips the usual pattern: Kling 3.0 Turbo — With Native Audio is $0.14/s at 1080p against $0.168/s for the standard model with audio, 17% cheaper, and $0.112/s against $0.126/s at 720p, 11% cheaper.
Money-saving notes
- Turbo is cheaper than standard when you need audio. $0.14/s vs $0.168/s at 1080p.

- Avoid 4K unless delivery requires it. $0.42/s against $0.112/s is $2.464 more for 8 seconds.
- Avatar is the cheapest row Kling publishes. $0.056/s at 720p, half the Kling 3.0 720p rate.
- Voiceover costs 17% more than on-camera speech in the Apparel Replicator line: $0.28/s vs $0.238/s at 1080p.
Worked example
30 avatar clips, 6 seconds each, 1080p:
30 × 6s × $0.112/s = $20.16
The same 30 clips at 4K on Kling 3.0 are 30 × 6 × $0.42 = $75.60.
FAQ
Is Kling's price per second or per Unit?
Per second. Kling publishes a Unit count and prices the Unit at $0.14, so a 0.8-Unit row is $0.112 per second. The table shows both.
What is the cheapest Kling model?
Avatar at 720p, $0.056 per second — $0.448 for 8 seconds. Among general video models, Kling 3.0 without native audio at 720p is $0.084 per second.
Why is 4K the same price with and without audio?
Because every 4K row in Kling's table is listed at 3 Units, $0.42 per second, regardless of the audio flag. Whether the output actually contains audio at 4K is not stated in the price row.
Do these rates include the web app subscription?
No. These are API rates from Kling's API price table. The consumer app's plan pricing is a separate product and is not in this file.
Is Kling cheaper through Runway?
Sometimes, on paper. Runway resells Kling 3.0 Standard without audio at $0.09/s, below Kling's own $0.112/s, but Runway's row does not state a resolution, so it is not a like-for-like comparison. Runway's Kling 4 at 1080p is $0.188/s. See the Kling vs Runway comparison.
