If you earn $80 an hour and work a standard full-time schedule, your gross pay is $166,400 a year. Taxes take a meaningful bite: after federal income tax, Social Security, and Medicare, a single filer keeps about $125,000 a year — roughly $10,417 a month. If you live in a state with income tax, your take-home will be a little lower; states with no income tax (like Texas and Florida) leave you with the full federal-only amount.
