Hourly Wage: Enter your hourly wage. Number of paid hours per week: Average number of hours you are paid for each work week. Number of days you work per week. Average number of days you work during each week: Annual Salary: This is what your hourly pay translates into per year, (HOURLY PAY X HOURS PER WEEK X 52.14).
Calculate the average number of regular and overtime hours and work out your weekly and annual regular and overtime pay. Add these together to determine your annual salary. 1  Suppose in a four week period, you work 50 hours, 45 hours, 42 hours and 47 hours. Find the average weekly hours with the equation (30 + 25 + 35 + 40) / 4 = 32.5. 2  If you earn $19 per hour, then calculate your annual salary with the equation (32.5 x $19) x 52 = $32,110. 3  Keep track of your weekly hours with spreadsheet software or a time-tracking app.
