AWS Amazon data transfer from E2 to S3 - the price of the issue?

Question

Amazon Web Services

Good afternoon. I use aws for the first time, I still can’t figure out some of the intricacies of prices.
I will describe the task: I want to raise a virtual machine to E2 (free version with 1GB of memory, etc.). I want to raise vpn on it and pick up 1c bases from client servers using it, put them in S3.
I'm interested in a specific question - is there a fee for transferring data from E2 to S3? If so, does the price depend on the transferred GB or requests?
How can I roughly calculate future expenses?
Thanks in advance for your replies!
PS goal - backup.

Answer 1

Free if EC2 and S3 are in the same region.

Answer 2

the fee is taken for everything
amazon has a calculator, if you have large volumes it is cheaper to keep your server
