It should be noted, how-ever, that only about 1 out of every 10 STEM workers has a high school diploma or less. Those with gradu-ate degrees in a STEM job earned more than $40 per hour, nearly $4.50 more per hour on average than those with non-STEM jobs.
The average, full-time, salaried employee works 40 hours a week. Based on this, the average salaried person works 2,080 (40 x 52) hours a year. To determine your hourly wage, divide your annual salary by 2,080. If you make $75,000 a year, your hourly wage is $75,000/2080, or $36.06. If you work 37.5 hours a week, divide your annual salary by 1,950 (37.5 x 52). At $75,000, you hourly wage is $75,000/1,950, or $38.46.
