Hi @petrong, and welcome :)
I believe the cost will depend on your location (or more specifically, the location of the test centre you decide to attend).
https://www.qt.io/qt-certification/ says:
The exams are organized by authorized PearsonVUE test centers. Please find more information on test centers near you from here.
So I suggest you sign up for an account at PearsonVUE, and follow the links to schedule an exam (if I remember correctly, you have to go that far to see the prices on their website), or contact PearsonVUE and ask them directly.
Cheers.
