Kling API pricing: what Kling charges per second, and per usable clip
Kling sells its video models three ways: in the Kling app on a credit subscription, inside other tools such as Runway, and direct through its own developer API, billed per second. Here is every current Kling API video rate on the official price list — Kling 3.0 with and without audio, 3.0 Turbo, 3.0 Omni, 2.6 and 2.5 Turbo — turned into what a 5, 10, 15, 30 or 60-second clip costs per try and per usable clip with retries, and how that compares with the app and Runway.

Quick answer
The cheapest Kling API rate is Kling 2.6 or Kling 2.5 Turbo at 720p without native audio: $0.042 per second — $1.26 per 30-second try and $3.78 per usable 30-second clip with 2 retries, rank 16= of the 210 verified rates on ClipCost. At 1080p it is $0.07 ($6.30). Kling 3.0 is $0.084 / $0.112 per second at 720p / 1080p without audio ($7.56 / $10.08 usable) and $0.126 / $0.168 with native audio ($11.34 / $15.12); 4K is $0.42 ($37.80). Kling 3.0 Turbo (audio included) is $0.112 / $0.14 and Kling 3.0 Omni $0.084–$0.14 without a reference video. The API is about 1.4× a fully used Kling app subscription (Kling 2.6 Standard mode $2.70) but roughly 2–5× cheaper than the same models inside Runway (Kling 2.5 Turbo $17.28, Kling O3 Standard $22.46).
New Oct 25, 2026: Kling’s own API is now the 14th tool in the ClipCost calculator, the pricing comparison, the cheapest ranking and the API ranking, with all 17 rates below verified today on the Kling API video pricing page (1 unit = $0.14 list price). Special modes (Motion Control, reference-video input, Kling O1, voice reference) are listed further down but not ranked.
Basis: Kling’s public list price in US dollars, 1 unit = $0.14, billed per second of output video; failed generations deduct no units. Package discounts, if any, are not applied (package sizes are not on the public price list). “Usable” = 3 attempts (1 try + 2 retries), the same maths as our calculator. Rank = position among the 210 verified text/image-to-video rates in the pricing comparison (usable 30s; ties share a rank). Kling app and Runway rows are valued at their entry annual plan’s price per credit (Kling Standard $0.0100, Runway Standard $0.0192), assuming you use all your credits; Kling app rates were last verified Oct 17, 2026. Cost only, no quality ranking. Some links on ClipCost are affiliate links (see footer); they never change these numbers.

Lengths from the Kling API video capability map (updated Oct 20, 2026). Kling 3.0 audio prices are labelled “no voice control” on the developer pricing table; a voice-control price is not listed. ⚑ Kling 2.6 audio: the capability map lists native audio as “Not Supported” for Kling 2.6 text/image-to-video, while the price list prices it at 1080p — the official pages disagree, so confirm in the API reference before you build on it.

Same source and date. These modes need a reference video, a motion source or a voice sample, so they are not comparable with plain text/image-to-video and stay out of the ranking. Avatar (from $0.056 per second at 720p) and Lip Sync ($0.07 per 5 seconds) are also on the price list. Kling 4.0 is listed as “Coming Soon” with preview prices only (see FAQ); it is live on the Runway API — see Kling 4.0 cost.
Cost per clip: 5s, 10s, 15s, 30s and 60s with retries
Each pair is one try and usable (3 attempts), cheapest first. Clips longer than a model’s maximum generation length (10s for Kling 2.6 / 2.5 Turbo, 15s for Kling 3.0) are several generations stitched together; the per-second price is the same.

The pattern holds for every model: the Kling app is cheapest if you use your whole subscription (about 71% of the API price per second on Standard annual credits, which expire after a month), the API is next and costs nothing when idle apart from packages you prepay, and Runway is roughly 2–5× the API for the same Kling models. Runway resolution names (Std / Pro) do not map one-to-one to Kling’s 720p / 1080p. Details: Kling app pricing, Kling 3.0 cost per video, Kling O3 cost, Kling 2.5 Turbo cost, Runway vs Kling cost.
Units, packages and what is not on the public page
- Units: the API deducts units; the public video price list values 1 unit at $0.14 (list price). Kling 2.6 at 720p is 0.3 units per second, Kling 3.0 at 1080p with audio 1.2.
- Prepaid packages: units come from “Video Generation API Resource Packages” bought on kling.ai/dev/pricing (Kling API quick start); a trial package is offered for testing and there is a custom package / business inquiry option. Package sizes, prices and any minimum purchase are not on the public static page — check them in your developer account. We have not verified any volume discount.
- Expiry: unused package balance is cleared when the package expires, and account balance is non-refundable (Kling API paid-service terms).
- Failures are free: failed generations deduct no units, but every successful attempt you throw away is billed — hence our 3-attempt “usable” maths.
- Concurrency does not increase when you buy more packages.
How to pay less for Kling video
- Draft on Kling 2.6 or 2.5 Turbo at 720p without audio ($0.042/sec), then render the keeper on Kling 3.0.
- Add audio in the edit unless you need lip-synced dialogue: native audio adds 50% on Kling 3.0 and doubles Kling 2.6 at 1080p.
- Making clips every week? The Kling app Standard plan is cheaper per second if you use all 660 credits a month; the API wins for bursty or automated use.
- Avoid Kling inside Runway unless you need Runway’s editor: the same Kling 2.5 Turbo second costs about 4.6× more on Runway Standard credits.
- Buy small packages first: balances expire, so match the package to what you will render in its validity period.

FAQ
How much does the Kling API cost per second?
On Kling's own developer API (list price, 1 unit = $0.14, checked Oct 25, 2026): Kling 2.6 and Kling 2.5 Turbo cost $0.042 per second at 720p and $0.07 at 1080p without native audio; Kling 2.6 with native audio is $0.14 per second (1080p only). Kling 3.0 is $0.084 / $0.112 per second at 720p / 1080p without audio and $0.126 / $0.168 with audio, and $0.42 at 4K. Kling 3.0 Turbo (audio included) is $0.112 / $0.14. Kling 3.0 Omni without a reference video is $0.084 / $0.112 silent and $0.112 / $0.14 with audio, and $0.126 / $0.168 with a reference video. You pay per second of output video.
How much does a 30-second Kling API video cost?
One 30-second try costs $1.26 on Kling 2.6 or 2.5 Turbo at 720p without audio, $2.52 on Kling 3.0 720p without audio, $3.78 on Kling 3.0 720p with audio and $5.04 at 1080p with audio. With 2 retries (3 attempts), a usable 30-second clip is $3.78, $7.56, $11.34 and $15.12. Kling 2.6 and 2.5 Turbo make 5 or 10-second clips and Kling 3.0 up to 15 seconds, so 30 seconds is several generations stitched together.
Is the Kling API cheaper than the Kling app or Runway?
Cheaper than Runway, dearer than a fully used Kling app subscription. Kling 2.6 at 720p without audio is $3.78 per usable 30 seconds on the API against $2.70 in Standard mode on Kling Standard annual credits (about 1.4 times), and Kling 3.0 720p without audio is $7.56 against $5.40. Inside Runway on Standard annual credits Kling 3.0 Std without audio is $15.55, Kling O3 Standard $22.46 (about 2.2 times the API's Kling 3.0 Omni 720p with audio) and Kling 2.5 Turbo $17.28 (about 4.6 times). The app numbers assume you use every subscription credit before it expires; the API has no monthly plan.
How does Kling API billing work?
Kling's developer API deducts units from prepaid resource packages that you buy on kling.ai/dev/pricing; the public video price list values 1 unit at $0.14 (list price), and every model is billed per second of output video. Failed generations deduct no units. Unused package balance is cleared when the package expires, account balance is non-refundable, and buying more packages does not raise your concurrency limit. A trial package is offered for testing. Package sizes, package prices and any minimum purchase are not shown on the public static price list, so check them in the developer console before you buy; ClipCost uses the $0.14 list price.
Does native audio cost extra on the Kling API?
Yes. Kling 3.0 is $0.084 per second at 720p without native audio and $0.126 with it (50% more), and $0.112 against $0.168 at 1080p. Kling 3.0 Omni is $0.084 against $0.112 at 720p. Kling 2.6 jumps from $0.07 to $0.14 per second at 1080p, and its audio mode is 1080p only. Kling 3.0 Turbo is only priced with audio. At 4K, Kling 3.0 and 3.0 Omni cost $0.42 per second with or without audio. Note: Kling's API capability map lists native audio as not supported for Kling 2.6 text and image-to-video while the price list prices it, so confirm before relying on Kling 2.6 audio.
How much will the Kling 4.0 API cost?
Kling 4.0 is listed as Coming Soon on the Kling API pricing page (checked Oct 25, 2026), with preview prices of 1.0 unit ($0.157) per second at 720p and 1.5 units ($0.235) at 1080p without video input. Kling says these prices are for preview only, cannot be used yet and that the official launch date and pricing will be announced separately, so ClipCost does not rank Kling 4.0. Note that the preview lists a different dollar value per unit than the $0.14 list price used for the current models.
