Can Physical Therapists afford to live in DeKalb County, IL?
The 30% rent guideline
A common rule of thumb says rent should stay under 30% of gross income. For a gross salary of $105,720 that ceiling is $2,643 a month. The one-bedroom Fair Market Rent of $1,155 is $1,488 under it, so rent fits the guideline.

Another way to see it: at $37.42 of take-home pay an hour, a one-bedroom takes about 7.1 working hours every week.
Splitting a two-bedroom
Sharing a two-bedroom at $1,481 a month means $741 each. Compared with renting a one-bedroom alone, that saves $4,974 a year. With a roommate, the yearly margin after the basics becomes $61,930.
How fast you can save
At $4,746 a month of margin, building a $10,000 emergency fund would take about 3 months. Setting aside half of the margin stretches the same goal to about 6 months. These figures ignore interest, raises and any spending beyond the four basics.
