To calculate the annual salary based on an hourly wage, you would multiply the hourly wage by the number of hours worked in a year. Typically, a full-time employee works about 40 hours per week for 52 weeks in a year.
So, for an hourly wage of $20 per hour:
$20/hour * 40 hours/week * 52 weeks/year = $41,600 per year
Therefore, earning $20 per hour would result in an annual salary of $41,600 before taxes and any deductions.
