For Registered Nurses earning the Clinton County, IL median of $83,180, they add up to $20,088.

Federal income tax
After the $15,750 standard deduction, taxable income is $67,430.

Can Registered Nurses afford to live in Clinton 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 $83,180 that ceiling is $2,080 a month. The one-bedroom Fair Market Rent of $1,104 is $976 under it, so rent fits the guideline. Put as a wage, covering a one-bedroom at the 30% guideline takes $21.23 an hour; the median for Registered Nurses is $39.99, which is 88% above that mark. Another way to see it: at $30.33 of take-home pay an hour, a one-bedroom takes about 8.4 working hours every week.
Splitting a two-bedroom
Sharing a two-bedroom at $1,349 a month means $675 each. Compared with renting a one-bedroom alone, that saves $5,154 a year. With a roommate, the yearly margin after the basics becomes $47,981.
How fast you can save
At $3,569 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.
