How credits work

What sets the credit price of a Kling4 generation, where you see that price before anything runs, how long credits last, and what happens when a job fails.

Credits are the one currency on Kling4: every Kling model draws from the same balance. You never have to guess the price, because it appears on the button before the job starts.

What makes a job cost more

The model. Each Kling model has its own rate. The pricing page lists the current credit costs.
Seconds. Longer clips cost more than short ones on the same model.
Resolution and quality. Higher output settings cost more per clip.
The kind of input. Some modes, such as motion control, are priced differently from text-to-video and image-to-video.

Seeing the price first

In the video generator the main button shows the credit cost, and it follows every change you make to the model, length, resolution or inputs. There is no charge you did not see.

Credits from subscriptions and credit packs each have their own validity period. The pricing page describes the current rules, and your credit history shows the expiry date of every grant. If you cancel a subscription, credits you already have keep their original expiry date.

Checking your balance

The credit badge in the generator shows your balance once you are signed in. For the full history, open your credit history page: it shows the balance, then every grant and deduction with its date and expiry.

Failed jobs and refunds

A generation that fails is not charged; if credits were already deducted for it, they return to your balance automatically. That is not a money refund: refunds of a purchase follow the refund policy, summarised in Cancel a subscription.

FAQ

How many credits will my video take?

It depends on the model, the clip length, the resolution and any extra options. Before you submit, the Generate button shows the exact amount for your current settings, and it updates whenever you change something.

Do I lose credits if a generation fails?

No. A failed generation is not charged, and if credits were already taken for a job that then fails, they go back to your balance automatically.

When do my credits expire?

Each grant of credits has its own expiry date, which depends on whether it came from a subscription or a credit pack. Your credit history page shows the expiry date of every grant.

I ran out of credits. What are my options?

Buy a credit pack and keep your current plan, or move to a plan with a bigger allowance. Packs never renew.
