It's actually pretty easy to calculate. Labor costs can account for up to 70% of total business costs so, out of $100, roughly $70mm is spent on salaries. The "one-third rule" for landlords to determine eligibility for rent means you can spend up to roughly 33% of your income on rent. So 33% out of $70mm is $23 million. You can say that 23% of every VC dollar goes towards landlords.
Also some of the employee's non-rent spending will go to local businesses which will spend some of that money on rent and some of that money on salaries and so on with the new set of employees.
