From gross pay to take-home pay
A salary of $44,180 does not arrive in full.

A common rule of thumb says rent should stay under 30% of gross income. For a gross salary of $44,180 that ceiling is $1,105 a month.

Sharing a two-bedroom at $3,697 a month means $1,849 each. Compared with renting a one-bedroom alone, that saves $13,854 a year. With a roommate, the yearly margin after the basics becomes $5,055, which turns the shortfall into a surplus.
