Alternate, polite word for "Fee" [closed]

I want to inquire about fee for Tai Chi course. But, the word "Fee" would not be polite for such martial art. Would there be any alternate word I could use, which is more polite and kind to ask about this.


Solution 1:

What about "contribution"? That's definitely much more polite.

Solution 2:

Think you're beating around the wrong bush. If it's not polite to ask about a fee, then it's not polite to charge one. Hence, if they are charging a fee, you can ask about it, using the word "fee".
