Thanks and Regards

here you go
echo "aa-bbb-cccc-ddd-ee" | awk -F"-" '{print length($0)-length($NF)}'

Assuming you're using a standards conforming shell (such as bash or ksh), this will also work:
echo "Last - is in column $((${#str} - ${#end}))"

and only uses shell built-ins.

With your sample string, it produces:
Last - is in column 16

# 6  
echo ${#start}

This is OK, as the shell's string index starts with 0:
echo ${str:${#start}:1}
