When i made a new drive it take some space for system file FAT32 take the less space, then NTFS, then ext4 my question how to know the space will be taken for the system before make the drive, if the drive 1giga or 100giga for FAT32, NTFS, ext4.

Edit: when make 10MB drive with FAT32 the size shown 9.9

when make 10MB drive with ext4 the size shown 8.1

the same thing with the bigger size there always some space used and there is no files on the drive, so where this space go, if it for the filesystem how i can calculate the space that will be taken before format the drive
