Can Dental Hygienists afford to live in McHenry 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 $100,260 that ceiling is $2,507 a month. The one-bedroom Fair Market Rent of $1,780 is $727 under it, so rent fits the guideline. Put as a wage, covering a one-bedroom at the 30% guideline takes $34.23 an hour; the median for Dental Hygienists is $48.20, which is 41% above that mark. Another way to see it: at $35.70 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 $55,179.
How fast you can save
At $3,824 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.
