An annual salary gives you a dollar figure for the entire year but does not break down the amount into an hourly wage. This information can be used to arm you for an upcoming job review or to evaluate the merits of a job offer. Breaking down your salary requires you to factor in vacation time, official holidays and floating holidays to obtain an accurate figure.
Calculate the exact number of days you work during a 12-month period. This figure only includes days you are actually in the office, so deduct vacation days and official holidays to arrive at the correct figure. For example, out of a total of 260 available work days, you may only have worked 240 days or fewer after deducting vacation and holidays.
Calculate the number of hours you worked during a 12-month period by multiplying the hours you worked per day by the number of days you worked during the year. For example, if you worked eight hours per day and 220 days in the year, your total number of hours worked during the year would be "220 x 8 = 1,760."
Divide your annual salary figure by your total hours worked during the year to obtain an accurate measure of your hourly wage. For example, if your annual salary is $50,000 and your annual hours worked is 1,760, your hourly wage would be calculated as "50,000/1,760 = $28.40."
