Credits explained
No app credits: Kling’s developer API deducts “units” from prepaid resource packages, billed per second of output video (list price 1 unit = $0.14 for video). Verified Oct 25, 2026 on the Kling API video pricing page (kling.ai/document-api/pricing/base/video; the HTML page is JS-rendered, the .md version and kling.ai/dev/pricing carry the same table): Kling 3.0 $0.084 / $0.112 per sec at 720p / 1080p without native audio, $0.126 / $0.168 with, $0.42 at 4K; Kling 3.0 Turbo (audio) $0.112 / $0.14; Kling 3.0 Omni (no reference video) $0.084 / $0.112 silent, $0.112 / $0.14 with audio, $0.42 at 4K, reference-video input $0.126 / $0.168; Kling 2.6 $0.042 / $0.07 silent, $0.14 with audio (1080p only); Kling 2.5 Turbo $0.042 / $0.07 (no native audio). Failed generations deduct no units; unused package balance is cleared when the package expires. Package sizes, prices and any minimum purchase are not shown on the static page — check kling.ai/dev/pricing before you buy.

Cost per finished video (before retries)
| Length | Cheapest calculable cost | Basis |
|---|---|---|
| 5s finished video (1 attempt, no retries) | $0.21 | Kling 2.6 or 2.5 Turbo · 720p, no native audio |
| 30s finished video (1 attempt, no retries) | $1.26 | Kling 2.6 or 2.5 Turbo · 720p, no native audio |
| 60s finished video (1 attempt, no retries) | $2.52 | Kling 2.6 or 2.5 Turbo · 720p, no native audio |
Retries multiply this: with 2 retries (3 attempts total) a 30s video costs roughly 3× the table price ($3.78 here). Use the calculator with your real retry count. Every rate per 5s–60s and vs the Kling app and Runway: Kling API pricing.
Watermark & commercial use
Watermark: API output — watermark rules not stated on the API pricing page; check the Kling API terms and the API reference.
Commercial: Check the Kling API paid-service terms (kling.ai/document-api/guides/protocols/paid-service) for output rights; API units and account balance are non-refundable.
Plan traps to know
- You prepay for unit packages: unused units are cleared when the package expires, and balance is non-refundable — buy only what you will use in the validity period.
- Package sizes, prices and minimum purchase are not on the public static pricing table (only the $0.14-per-unit list price) — check kling.ai/dev/pricing in your account; volume discounts may change the effective rate.
- Native audio roughly doubles the price: Kling 3.0 at 720p is $0.084/sec silent vs $0.126 with audio, and Kling 3.0 Turbo has no silent price at all.
- Kling 2.6 and 2.5 Turbo generate 5s or 10s clips only; Kling 3.0 / Turbo / Omni 3-15s. 30 seconds means stitching several generations.
- Same models cost less in Kling’s own app on a subscription (Kling 2.6 Standard mode 3 credits/sec = $0.03/sec on Standard annual) and much more inside Runway (Kling 3.0 Std 9-13 credits/sec).
