In addition to your lost+found blocks, there are blocks used
for superblocks, bitmaps, group descriptors, inodes, journal,
indirect blocks, and probably others too.

As a test I just created an empty 32MB ext3 filesystem:

# mke2fs -j /dev/VG0/test

It has 14% used:

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VG0-test     31729      4127     25964  14% /test
