Multiply this figure by 52, the number of weeks per year, to work out your annual salary. 1  For instance, if you work 40 hours per week and you earn $19 per hour, calculate your weekly salary with the equation 40 x $19 = $760. For example, suppose you earn an annual salary of $49,400 before bonuses, and your company has decided to award you a 2.5 percent profit sharing bonus. 2  Calculate the amount of the bonus with the equation $49,400 x .025 = $1,235. 3  Calculate total annual salary with the equation $49,400 + $1,235 = $50,635.
