You may say:
How much is ear piercing?

One common mistake is "How much to do" or "How to do something"
We never begin a sentence with "How to .... ?" We always say "How do you ...?"

E.g. How do you train your dogs? How do you say this in French? How do you tell if it's fake or not?

In your case, it's grammatically incorrect to say "How much to do ... ?"
You should say "How much is ... ?"
