From gross pay to take-home pay
Three separate tax bills sit between the gross salary and the bank account: federal income tax, FICA, and state income tax. For Cashiers earning the San Diego County, CA median of $37,020, they add up to $5,639.

Federal income tax
After the $15,750 standard deduction, taxable income is $21,270. Federal brackets are marginal, so only the slice of income above each threshold is taxed at the higher rate; the last dollars of this salary fall in the 12% bracket. The resulting federal income tax is $2,314, an effective 6.3% of gross pay, well below the 12% marginal rate because the lower brackets are cheaper.
Social Security and Medicare (FICA)
Payroll taxes are a flat percentage of wages. Social Security takes 6.2% up to a wage base of $176,100, which costs $2,295 on this salary. Medicare takes 1.45%, or $537. FICA totals $2,832, which is 7.6% of gross pay.
State income tax in California
California income tax on this salary is $493 a year, or 1.3% of gross pay, after the state's own deductions and exemptions are applied. That is 21% of the federal income tax bill, and it comes out to $41 a month. Local taxes such as county or city income taxes are not included, so a few jurisdictions may withhold slightly more.

Rent
Housing is the largest line in most budgets. For San Diego County, CA, HUD sets the Fair Market Rent for a one-bedroom unit at $2,335 a month ($28,020 a year), and at $2,823 for two bedrooms. For Cashiers, a one-bedroom absorbs 89.3% of take-home pay and 75.7% of gross pay.
Food

Energy and gasoline
Using California residential prices from the Energy Information Administration and national household averages for consumption, electricity costs about $3,378 a year and other home energy such as natural gas about $751, for $4,129 in total. Gasoline in California averages $4.42 per gallon; at about 463 gallons a year (11,106 miles at 24 miles per gallon) fuel adds $2,047.

Can Cashiers afford to live in San Diego 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 $37,020 that ceiling is $926 a month. The one-bedroom Fair Market Rent of $2,335 is $1,410 over it, so rent breaks the guideline. Put as a wage, covering a one-bedroom at the 30% guideline takes $44.90 an hour; the median for Cashiers is $17.80, which is 60% below that mark. Another way to see it: at $15.09 of take-home pay an hour, a one-bedroom takes about 35.7 working hours every week.
Splitting a two-bedroom
Sharing a two-bedroom at $2,823 a month means $1,412 each. Compared with renting a one-bedroom alone, that saves $11,082 a year. With a roommate, the yearly margin after the basics becomes $4,832, 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 $37,020 median, lower housing costs than the $2,335 one-bedroom rent, or a second income.
