I wrote this a long time back for myself. It might suffice your needs.
Cut paste the following code in a file say: dirsize, chmod +x dirsize
and execute.

#-CUT & PASTE---------------------------------------------------------
#/bin/bash

IGNORE='proc /dev /sys /initrd /mnt /media'

# This script produces a list of dir size. Selects only MB and above entries.

# Arg is the dir name else pwd is selected
if [ -z "$1" ]; then
        SDIR=`pwd`
    OutPut=/tmp`pwd`
else
        SDIR=$1
    OutPut=/tmp/${USER}/${1}
fi

echo "Output file is ${OutPut}/dir-size.out"

mkdirhier ${OutPut} && ls -lAR --si --ignore="${IGNORE}" ${SDIR}|grep 'total' -B1|grep '^total[[:space:]][0-9.]*[mMgG][[:space:]]*' -B1 >${OutPut}/dir-size.out 2>&1
echo -e "\nTotal Size Of Dir $SDIR" >>${OutPut}/dir-size.out 2>&1
du -ach ${SDIR}|grep "[[:space:]]total$" >>${OutPut}/dir-size.out 2>&1

less ${OutPut}/dir-size.out
