Can Registered Nurses afford to live in Kane 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 $100,490 that ceiling is $2,512 a month.

Put as a wage, covering a one-bedroom at the 30% guideline takes $34.23 an hour; the median for Registered Nurses is $48.31, which is 41% above that mark. Another way to see it: at $35.78 of take-home pay an hour, a one-bedroom takes about 11.5 working hours every week.
Splitting a two-bedroom
Sharing a two-bedroom at $2,011 a month means $1,006 each. Compared with renting a one-bedroom alone, that saves $9,294 a year. With a roommate, the yearly margin after the basics becomes $55,330.
How fast you can save
At $3,836 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.
