Can Automotive Service Technicians and Mechanics afford to live in Madison 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 $58,190 that ceiling is $1,455 a month. The one-bedroom Fair Market Rent of $1,104 is $351 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 Automotive Service Technicians and Mechanics is $27.98, which is 32% above that mark. Another way to see it: at $22.19 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 $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 $31,034.
How fast you can save
At $2,157 a month of margin, building a $10,000 emergency fund would take about 5 months. Setting aside half of the margin stretches the same goal to about 10 months. These figures ignore interest, raises and any spending beyond the four basics.
