Highest earning films by cost to earning ratio

I'm interested to know if there is a list of movies ranked by cost-to-earning ratio, defined as something like (box-office sales) / (film budget).

Some data which can be used to construct such a list is on Wikipedia, often listed in the info box for each film under 'Budget' and 'Box office'.

box-office

Yes there is. I found it at the-numbers.com. I will work on formatting this better.
