Can First-Line Supervisors of Mechanics, Installers, and Repairers afford to live in Jefferson County, CO?
The 30% rent guideline
A common rule of thumb says rent should stay under 30% of gross income. For a gross salary of $86,800 that ceiling is $2,170 a month. The one-bedroom Fair Market Rent of $1,831 is $339 under it, so rent fits the guideline. Put as a wage, covering a one-bedroom at the 30% guideline takes $35.21 an hour; the median for First-Line Supervisors of Mechanics, Installers, and Repairers is $41.73, which is 19% above that mark. Another way to see it: at $31.95 of take-home pay an hour, a one-bedroom takes about 13.2 working hours every week.
Splitting a two-bedroom
Sharing a two-bedroom at $2,169 a month means $1,085 each. Compared with renting a one-bedroom alone, that saves $8,958 a year. With a roommate, the yearly margin after the basics becomes $46,568.
How fast you can save
At $3,134 a month of margin, building a $10,000 emergency fund would take about 4 months. Setting aside half of the margin stretches the same goal to about 8 months. These figures ignore interest, raises and any spending beyond the four basics.
