Kling 4.0 Pricing: What Each Model Costs Per Video

You buy credits once and spend them per second of output. Plans are $19.90, $49.90 and $99.90, and models charge from 1 credit per second on Kling 2.6 and Avatar 2.0 up to 7 on Kling 4K. A second of finished video therefore costs roughly $0.08 to $0.70 depending on what you generate. A 10-second Kling 2.6 clip is about $0.77, the same length on Kling 3.0 Standard is about $2.31, and at 4K it is about $5.38. There is no subscription, and credits do not expire.

Credits scale with output length, so it is the per-second rate times the duration. Kling 3.0 Standard at 3 credits per second makes a 10-second clip 30 credits and a 30-second clip 90. Kling 3.0 Pro is 4 per second, Kling 4K is 7, and Omni multi-image reference is 2 silent or 3 with audio. Kling 2.6 is billed by fixed clip length instead — 5 credits for 5 seconds, 10 for 10 seconds. Avatar has minimum charges: under 5 seconds bills as 5 credits on Standard, under 15 seconds as 15 on Pro. A failed render costs the same as a successful one.

Kling 4.0 without video inputs costs 4 credits per second at 720p or 6 at 1080p. With reference videos, add the output duration to the total duration of all input videos, round that combined duration up to a whole second, and charge 3 credits per second at 720p or 5 at 1080p. For example, an 8-second output with one 8-second reference costs 80 credits at 1080p. Audio instructions do not change these rates.

New accounts get starter credits with no card required, enough to run your own prompt and judge output on your own material. It does not cover 4K or long takes — a single 30-second 4K clip is 210 credits, more than the entire Starter plan. There is no monthly free refill because there is no monthly billing cycle; the allowance is one-time per account, and it is sized to answer whether the output suits your work rather than to produce a project.

No. This site sells one-time plans rather than monthly billing, so there is nothing to cancel, no auto-renewal, and no Kling AI pricing yearly commitment to weigh up. If you searched for Kling AI pricing per month, the closest equivalent here is simply buying a plan when you need one. The trade-off is that there is no recurring-volume discount — the only discount is plan size, and it does not go beyond the largest one. Credits stay in your balance until you spend them.

It depends on what you generate more than on what you pay. Kling 2.6 at about $0.08 per second is inexpensive for usable output with audio and lip-sync included in the rate. Kling 4K at about $0.54 is nearly seven times that, and the quality difference is not seven times on every shot — it matters on a graded deliverable for a large screen and barely at all on a social cut. The teams who get the most value test on cheap models and spend the expensive credits once, on a shot they already know works.

Kling 2.6 Standard and Kling Avatar 2.0 Standard, both at 1 credit per second — about $0.077 on the largest plan. Avatar carries a 5-credit minimum under 5 seconds, so for very short output Kling 2.6 is effectively cheapest. Next up is Omni multi-image reference at 2 credits per second silent, which is cheaper than any standard 3.0 model and more controllable. The most expensive is Kling 4K at 7 credits per second.

No. Plans are one-time purchases and unused credits stay in your balance indefinitely. There is no monthly reset, no expiry date and no deadline to consume against. If you generate in bursts — a campaign one month, nothing the next — the balance is still there when you come back, which is the main reason this site sells credits rather than subscriptions.

Yes, and balances combine. Because the only discount is plan size, the cheapest route to a given number of credits is a single larger plan rather than several small ones. If you know your project size in advance, size it once.
