Kling 4.0 Pricing: What Each Clip Really Costs

The short answer

Kling 4.0 on Open Kling is billed per second in credits. One credit is $0.01. A 5 second clip costs 9 credits and a 10 second clip costs 18, at both 720P and 1080P. There is no subscription: you buy a one-time pack, and the credits stay in your balance until you use them.

That is enough to estimate a shoot. The rest of this guide shows how the three packs map to real output and where the cost can drift.

What one generation costs

The rate is simple, but the settings interact:

• 5 second clip: 9 credits.
• 10 second clip: 18 credits.
• 720P or 1080P: the same per-second rate on Open Kling.
• Text-to-video or image-to-video: the same rate.
• First and last frame control: the same rate, because it is still one generation at the chosen duration.

The model bills by the second and rounds up, so there is no partial-second discount. In practice, you choose 5 or 10 seconds before you generate, and the studio shows the credit cost before you confirm.

What each pack covers

Here is the arithmetic at the 5 second rate, which is the easiest unit to plan with:

| Pack | Price | Credits | 5s clips | 10s clips | | --- | --- | --- | --- | --- | | Starter | $9.99 | 999 | about 111 | about 55 | | Standard | $49.99 | 5,199 | about 577 | about 288 | | Premium | $99.99 | 10,999 | about 1,222 | about 611 |

The larger packs include bonus credits, which is why the effective price per credit drops. At the entry pack, 999 credits cost $9.99; at the top pack, 10,999 credits cost $99.99. If you already know you will produce a batch, the larger pack is cheaper per clip. If you are still learning the model, the starter pack is enough for more than a hundred short tests.

Why 1080P does not cost more here

Some platforms charge a higher per-second rate for 1080P. Open Kling keeps the same rate at both resolutions, so the decision is about generation time and use case rather than budget. Test at 720P because it is faster to review, then generate the final take at 1080P without changing the math.

This is also why resolution is a poor place to save credits. The real savings come from generating fewer failed shots: one clear prompt at 1080P is cheaper than five confused tests at 720P.

How to estimate a real project

Start from the edit, not the model. A 30 second social video built from 5 second shots needs six successful clips. If roughly one in three generations is usable, budget for eighteen generations, or 162 credits. A 60 second product video built from 10 second shots needs six usable clips, and at the same hit rate that is eighteen generations at 18 credits, or 324 credits.

The numbers are not a promise about your hit rate. They are a way to turn an edit into a credit budget before you start, so a project does not stall halfway through. Track how many attempts each shot takes; that ratio is the number that actually controls cost.

What you are not paying for

There is no monthly seat, no renewal date, and no cancellation flow. Credits do not expire, so a pack bought for one project can be used for the next one. The trade-off is that you pay up front rather than spreading the cost across a subscription, which is better for occasional production and worse if you need a predictable monthly invoice.

For teams, the practical question is simple: estimate the clips, multiply by attempts, and buy the pack that covers it with some headroom. The pricing page lists the current packs and credit rates; the Kling 4.0 overview explains the settings behind the numbers.

FAQ

How many credits is a 5 second Kling 4.0 video?

Nine credits. A 10 second video is 18 credits. On Open Kling, 720P and 1080P use the same per-second rate.

How much does a 5 second clip cost in dollars?

At the stated rate of one credit equals $0.01, a 9 credit clip is about $0.09. The effective price per credit is slightly lower on the larger packs because they include bonus credits.

Do credits expire?

No. Credits stay in your balance until you use them, regardless of which pack you bought. There is no monthly reset.

Can I buy a pack without subscribing?

Yes. Every pack is a one-time purchase. Nothing renews automatically, and there is no subscription to cancel.

Is image-to-video more expensive than text-to-video?

No. Both cost the same per second. First and last frame control also uses the standard rate because it is one generation at the selected duration.

What happens if a generation fails?

The studio reports job status. Failed jobs are handled by the platform rather than charged as a finished clip; check the credit history in your account if a balance looks wrong.

Conclusion

Kling 4.0 pricing comes down to one number: 9 credits per 5 seconds, 18 per 10 seconds. Choose a pack based on how many usable clips you need, not on how many generations you can afford, and keep a third of the budget for retries. When the shot list is ready, open the studio and check the credit cost shown before each run.
