If you're integrating Kling's video generation API into a project, one of the first questions you'll hit is: how much is this actually going to cost at scale? This guide breaks down every pricing tier for Kling 3.0, Kling O3, Kling O1, and Motion Control so you can budget accurately before you start building.

How Kling Billing Works
Kling bills per second of output video, rounded to the nearest integer. The final cost depends on four variables:
- Model (Kling 3.0, Kling O3, Kling O1)
- Mode (Text-to-Video, Image-to-Video, Motion Control)
- Resolution (720p or 1080p)
- Audio (with or without)
Kling 3.0 Text-to-Video
Duration range: 3–15 seconds
| Resolution | Without Audio | With Audio |
|---|---|---|
| 720p | $0.075/sec | $0.113/sec |
| 1080p | $0.100/sec | $0.150/sec |
Quick cost checks:
- 5-sec 720p no audio: $0.38
- 10-sec 1080p no audio: $1.00
- 15-sec 1080p with audio: $2.25
Kling O3 Text-to-Video
Duration range: 3–15 seconds
| Resolution | Without Audio | With Audio |
|---|---|---|
| 720p | $0.075/sec | $0.100/sec |
| 1080p | $0.100/sec | $0.125/sec |
O3 costs less than 3.0 when audio is included — worth noting if you're generating at volume.
Quick cost checks:
- 8-sec 720p with audio: $0.80
- 15-sec 1080p with audio: $1.88 (vs $2.25 for 3.0)
Kling O1 Image-to-Video
Fixed duration options: 5 seconds or 10 seconds
| Duration | Price | Per-second rate |
|---|---|---|
| 5 seconds | $0.556 | $0.111/sec |
| 10 seconds | $1.111 | $0.111/sec |
Flat pricing, no audio options. Good for product image animation.
Kling 3.0 Motion Control
For precise animation control with motion paths and keyframes.
Duration depends on reference type:
- Image reference: up to 10 seconds
- Video reference: up to 30 seconds
| Resolution | Rate |
|---|---|
| 720p | $0.113/sec |
| 1080p | $0.151/sec |
Max cost scenario: 30-sec 1080p = $4.53
Model Selection Guide
| Use case | Recommended | Cost |
|---|---|---|
| Budget / drafts | Kling O3 720p no audio | $0.075/sec |
| Social content with audio | Kling O3 720p with audio | $0.100/sec |
| Marketing / presentation | Kling O3 1080p with audio | $0.125/sec |
| Premium production | Kling 3.0 1080p with audio | $0.150/sec |
| Image animation | Kling O1 | $0.111/sec flat |
| Complex animation | Motion Control 1080p | $0.151/sec |
Audio Pricing Premium
Adding audio increases cost by:
- Kling 3.0: +$0.038–$0.050/sec (+50%)
- Kling O3: +$0.025/sec (+25–33%)
For high-volume pipelines without audio requirements, skipping audio saves significantly.
Real-World Scenarios
Social media campaign — 10 videos × 5 sec, 720p, with audio:
- Kling 3.0: $5.65
- Kling O3: $5.00 (save $0.65)
Product demo series — 5 videos × 12 sec, 1080p, with audio:
- Kling 3.0: $9.00
- Kling O3: $7.50 (save $1.50)
Image gallery animation — 20 images × 10 sec:
- Kling O1: $22.22 total
Cost Optimization Tips
- Prototype at 720p before committing to 1080p production runs
- Skip audio during iteration — add only to final outputs
- Use O3 for volume — cheaper than 3.0 with nearly equivalent quality
- Reserve Motion Control for shots that actually need precise path control
- Automatic fallback is built in — if a model is unavailable, Kling routes to the next cheapest option automatically
