To turn a yearly salary into an hourly wage, divide it by the hours you work in a year. A standard full-time job is 40 hours a week, or 2,080 hours a year — so $40,000 a year is about $19.23 an hour, $60,000 is about $28.85, and $100,000 is about $48.08. The calculator above also runs in reverse and estimates your take-home pay once federal tax, Social Security, Medicare, and state income tax come out.
