How much is a professor subsidized?

On average, full-time faculty members at the University of New Mexico’s
Gallup campus were being subsidized to the tune of $10,554 apiece.

The word subsidization, in this context, refers to the subsidy from the university and not from government per se.  That’s the difference between the cost of the professor minus the revenue he or she brings in from tuition.  Here is the full article, with further links.  I am not sure how this estimate allocates various fixed costs (does a professor have to "pay for" the lawn care service?), but for the time being does that matter?  The important truth is that while universities think in these terms all the time, they are rarely if ever willing to make their implicit estimates public or see how those estimates might be improved.
