To turn an hourly wage into an annual salary, multiply your rate by the hours you work each week and then by 52 weeks. A standard full-time job is 40 hours a week, or 2,080 hours a year — so a $20 hourly wage is $41,600 a year, $30 an hour is $62,400, and $50 an hour is $104,000. 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.
