Thanks for your replies.
It still seems a lot of money to pay for the overheads of a university. When you take into account the thousands of undergraduate and postgraduate fees the university takes each term, the overhead costs and staff salaries must amount to just a fraction of the total income the university receives from fees.
Universities even sell branded merchandise like scarves, pens, T-shirts etc. Then there are the bars and cafes on campus that add to the income of the university. Not to mention the student union membership costs as well. Also, don’t forget, the fees charged for their continuing education and night school programs. It must come to millions—just for one term!
