You mean: it is more than you expected? If so, you can try
du -sh /home/*
to see which subdirectory holds the biggest chunk, and slowly
work your way down the directory tree (note: this will exclude
the dot files and directories, because the glob ("*") doesn't
include them, at least usually. If you suspect one of those,
better do
du -sh $(ls -A /home)
or something similar)

Others have chimed in with good ideas. First, 0.5G seems reasonable
for "file system internal use" -- inodes, possibly journal, etc.
On my box:
tomas@trotzki:~$ sudo du -sh /home
[sudo] password for tomas:
368G /home
tomas@trotzki:~$ df -h
Filesystem Size Used Avail Use% Mounted on
[...]
/dev/mapper/trotzki-home 640G 368G 241G 61% /home
That's (368 - 241) / 368 -- around 35 percent (it's an ext4 file system).
