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 Medical Assistants earning the St. Johns County, FL median of $42,600, they add up to $6,242. The result is $36,358 of take-home pay a year ($3,030 a month), based on a single filer using the standard deduction.
Put another way, of every $100 earned, about $15 goes to taxes and $85 reaches the paycheck. The overall effective tax rate is 14.7%.
Federal income tax
After the $15,750 standard deduction, taxable income is $26,850. 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 $2,984, an effective 7.0% 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 $2,641 on this salary. Medicare takes 1.45%, or $618. FICA totals $3,259, which is 7.6% of gross pay.
State income tax in Florida
Florida does not tax wage income, so the state income tax line for Medical Assistants in St. Johns County, FL is $0. That alone leaves more in the paycheck than the same salary would in a state with an income tax. For scale, a hypothetical flat 5% state tax on this salary would cost about $2,130 a year, so the absence of a state tax is worth roughly $178 a month.

Can Medical Assistants afford to live in St. Johns County, FL?
The 30% rent guideline
A common rule of thumb says rent should stay under 30% of gross income. For a gross salary of $42,600 that ceiling is $1,065 a month. The one-bedroom Fair Market Rent of $1,421 is $356 over it, so rent breaks the guideline. Put as a wage, covering a one-bedroom at the 30% guideline takes $27.33 an hour; the median for Medical Assistants is $20.48, which is 25% below that mark. Another way to see it: at $17.48 of take-home pay an hour, a one-bedroom takes about 18.8 working hours every week.
Splitting a two-bedroom
Sharing a two-bedroom at $1,694 a month means $847 each. Compared with renting a one-bedroom alone, that saves $6,888 a year. With a roommate, the yearly margin after the basics becomes $18,832.
How fast you can save
At $995 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.
