How much does Kling AI cost?
Kling AI bills its API by the second of generated video, priced in Units where 1 Unit is $0.14 at list price. The per-second rate then depends on three things: which Kling 3.0 model you use, the resolution, and whether you turn on native audio. Once you know those, the cost of any clip is simple multiplication.
This guide uses Kling's own published API rates — not a reseller's marked-up numbers — to show exactly what each model and resolution costs, where native audio adds to the bill, and how to estimate a clip before you spend on it. Figures are Kling's list prices as of mid-2026; Kling adjusts them, so treat them as the current structure and ballpark.
The short answer
Kling's API is priced per second in Units, with 1 Unit = $0.14. Across the whole model range, a 5-second 720p clip can cost anywhere from about $0.14 (the older Kling 1.0 at $0.028/s) to over $2 (4K on a flagship model at $0.42/s). On the current Kling 3.0 with no audio, 720p is 0.6 Units — about $0.084/s, so a 5-second clip is roughly $0.42.
Three levers set the price: the model version, the resolution, and native audio. Older and lighter models are cheaper per second, resolution moves the price the most (720p → 1080p → 4K), and native audio adds a premium on top. Length is your direct multiplier on all of it.
Kling 3.0 (current flagship) API pricing — per second
Kling's own list prices, 1 Unit = $0.14, per second of output. 4K is a flat 3.0 Units ($0.42)/s where offered.

| Kling 2.6 — no audio | 720p 0.3 Units ($0.042)/s · 1080p 0.5 Units ($0.07)/s. Native-audio and motion-control variants cost more (up to $0.168/s at 1080p). |
|---|---|

Kling add-on features — Avatar, Lip Sync, Audio
Beyond video generation, Kling charges separately for avatar, lip-sync, and audio features — useful to know if you're building a full pipeline.
| Avatar (per second) | 720p 0.4 Units ($0.056)/s · 1080p 0.8 Units ($0.112)/s. |
|---|---|
| Lip Sync | 0.5 Units ($0.07) per 5 seconds. |
| Text-to-Audio / Video-to-Audio | 0.25 Units ($0.035) per call each. |
| TTS / Custom Voice / Face Recognition | 0.05 Units ($0.007) per call each. |
| Image Recognition | 0.1 Units ($0.014) per call. |
The two levers that move the price most: resolution and audio
Resolution is the biggest driver. On Kling 3.0 with no audio, going from 720p (0.6 Units) to 1080p (0.8 Units) is a modest step, but jumping to 4K (3.0 Units) multiplies the per-second rate five times over. Unless the delivery format truly needs 4K, staying at 1080p is dramatically cheaper.
Native audio is the second lever. On Kling 3.0, turning audio on raises 720p from 0.6 to 0.9 Units and 1080p from 0.8 to 1.2 Units — roughly a 50% premium. That's often worth it because it saves a separate scoring or dubbing step, but if you were adding your own soundtrack anyway, the no-audio tier is the cheaper path.
How to estimate a Kling clip's cost
Two minutes of math before you generate. Everything is per-second, so this is just multiplication.
- 1
Pick the model, resolution, and audio setting
Start from the table: e.g. Kling 3.0, 1080p, no audio is 0.8 Units ≈ $0.112/s. Choose the cheapest combination that meets the bar for the shot.
- 2
Multiply the per-second rate by your length
At $0.112/s, a 5-second clip is about $0.56 and a 10-second clip about $1.12. Length is your direct multiplier — generate only what you'll use.
- 3
Check whether 4K is really needed
4K is a flat $0.42/s — roughly four to five times the 1080p rate. A 5-second 4K clip is about $2.10 versus about $0.56 at 1080p. Reserve 4K for final delivery that genuinely requires it.
- 4
Multiply by your realistic iteration count
You rarely nail the shot first try. If you expect three or four attempts to get a keeper, multiply the single-clip cost by that — the iteration count is the number most people forget when budgeting.
Questions fréquentes
- Is Kling AI free?
- Kling offers a limited free allowance in its consumer app — a small pool of credits that refresh, enough to try it but not to produce at volume. Sustained use means either a paid membership in the app or paying per second on the API (priced in Units, 1 Unit = $0.14). There is no unlimited free tier.
- How much does a Kling AI video cost?
- On Kling's API, pricing is per second in Units (1 Unit = $0.14). On the current Kling 3.0 with no audio, 720p is 0.6 Units ≈ $0.084/s (about $0.42 for 5 seconds) and 1080p with native audio is 1.2 Units ≈ $0.168/s (about $0.84 for 5 seconds). 4K is a flat 3.0 Units ≈ $0.42/s (about $2.10 for 5 seconds). Older models are cheaper — Kling 2.5 Turbo and 2.6 start at 0.3 Units ($0.042)/s at 720p.
- Does Kling charge extra for audio?
- Yes. On Kling 3.0, turning on native audio raises the per-second rate by roughly 50% — 720p goes from 0.6 to 0.9 Units and 1080p from 0.8 to 1.2 Units. If you plan to add your own soundtrack, the no-audio tier is cheaper; if you want sound generated in one pass, the audio premium can save a separate production step.
- What's the cheapest way to use Kling?
- The lowest per-second video rates are the older models with no audio at 720p: Kling 1.0 at 0.2 Units ($0.028)/s, or Kling 2.5 Turbo and 2.6 at 0.3 Units ($0.042)/s among current-generation models. Draft there, then generate the final on your target model at 1080p. Avoid 4K (a flat $0.42/s) and the Master models ($0.28/s) unless the output truly requires them.
- How much does Kling image generation cost?
- Kling also generates images, billed per image. Text-to-image on Kling Image 3.0 is 8 Units ($0.028) per 1K/2K image; 4K is 16 Units ($0.056). The older Kling Image 2.0/2.1 text-to-image is cheaper at 4 Units ($0.014) per image, and Kling Image 1.0 is just 1 Unit ($0.0035) per image. Multi-image and outpainting operations cost more (16 Units / $0.056 and up).
