Differences in password hash calculations

I would like to make sure I understand the /etc/shadow file, especially the salt/hash part.
Each line is in the format:
username:passwd:last:may:must:warn:expire:disable:reserved
The passwd field is in the format : $x$salt$hash
Now, I take the hash (from the root user for example) and translate it in base64 (standard) with the command:
tr ./0-9A-Za-z A-Za-z0-9+/ hash
Why does an online hash calculator of "salt+password" give a different result?
I use a SHA-512 hash function according to the $6$ before the salt value.
I compare the two hash strings in the base64 standard encoding.
I can create the same hash string with the mkpasswd command using the salt but I can't figure out why I can't do that with an online hash calculator.
Thank you for your help.
