There are two papers available on the ICANN component of the costs.

See:

and

There is also a paper on a benchmarking study on what is involved in
operating a registry.   This was conducted by KPMG and compared 7 gTLDs
and 6 ccTLDs across 10 countries.

Note that there are also some letter of credit requirements etc to be
able to provide funding to operate a registry for I think three
additional years, if a registry operator chooses to cease providing that
function.
