Can Miscellaneous Assemblers and Fabricators afford to live in Contra Costa County, CA?
The 30% rent guideline
A common rule of thumb says rent should stay under 30% of gross income. For a gross salary of $60,250 that ceiling is $1,506 a month. The one-bedroom Fair Market Rent of $2,290 is $784 over it, so rent breaks the guideline. Put as a wage, covering a one-bedroom at the 30% guideline takes $44.04 an hour; the median for Miscellaneous Assemblers and Fabricators is $28.97, which is 34% below that mark. Another way to see it: at $23.48 of take-home pay an hour, a one-bedroom takes about 22.5 working hours every week.
Splitting a two-bedroom
Sharing a two-bedroom at $2,805 a month means $1,403 each. Compared with renting a one-bedroom alone, that saves $10,650 a year. With a roommate, the yearly margin after the basics becomes $22,387.
How fast you can save
At $978 a month of margin, building a $10,000 emergency fund would take about 11 months. Setting aside half of the margin stretches the same goal to about 22 months. These figures ignore interest, raises and any spending beyond the four basics.
