How much is the SEC fee?

Excuse me, I was wondering if you could clarify something for me regarding the SEC fee. I understand that the Securities and Exchange Commission imposes a fee on certain transactions, but I'm not entirely clear on the exact amount. Could you provide me with a general overview of how the SEC fee is calculated, and what the typical range of fees might be? I'm trying to budget for an upcoming investment, and I want to make sure I have all the necessary funds to cover any associated costs. Thank you for your time and assistance.
