How much does Coinbase take from you?

Excuse me, could you please clarify for me the fees that Coinbase charges when using their platform? I'm interested in understanding the specific percentages or amounts that they deduct from transactions, both for buying and selling cryptocurrency, as well as any other potential charges that may apply. I'd appreciate it if you could provide me with a comprehensive overview of their fee structure, as it's essential for me to make informed decisions regarding my investments. Thank you.
