What is the % you pay for renting an apt ?

What is the % you pay for renting an apartment in relation to your net salary?

I would include the following points in the comments if you wish. If you keep the format it is easier to read the comments.

- % amount

-Location (country/city)
-Age/age range
-Immigrant / non-immigrant
-shared apartment (y/n)
-do you pay around the average price, or is it above or below it?
- apartment size , city center / surroundings
- notes

Calculation shortcut for math adverse people:

% = [your rent everything included] * 100 / [net salary]
