 15MB would be the "installed size", I presume.
Debian packages are compressed.  Thus you would
probably get a more accurate estimate by adding
up the size of the .deb files.  Some files grow
a lot when installed, others don't.

 How many megabytes are used before dpkg takes
over the installation process?
