Can Dining Room and Cafeteria Attendants and Bartender Helpers 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 $39,310 that ceiling is $983 a month. The one-bedroom Fair Market Rent of $2,290 is $1,307 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 Dining Room and Cafeteria Attendants and Bartender Helpers is $18.90, which is 57% below that mark. Another way to see it: at $15.93 of take-home pay an hour, a one-bedroom takes about 33.2 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 $6,689, which turns the shortfall into a surplus.
How fast you can save
With no monthly margin after the four basics, saving requires a change on one side of the ledger: higher pay than the $39,310 median, lower housing costs than the $2,290 one-bedroom rent, or a second income.
