How much robux does Roblox take from each UGC sale?

Hello!
I am a developer and new blender artist! I am soon planning on applying for the UGC program. All throughout the forums I could not find a current answer to this question: How much of the robux does Roblox take from each UGC sale? I want to know if it is really worth it to join the program.
Once I get an answer I will close this post.

I think it’s 70%

If you put a UGC for sale, and its 100 robux, you will get 30 robux because 70% of 100 is 30%

Since so many people are already in it, I don’t think it’s worth it unless you are uploading it for someone and you get paid for it
