Almost all office administrator jobs are salaried jobs and not by the hour. It really depends on where you work. At most places the average salary is between $30,000 to $45,000 depending on your degree, experience, etc. At middle sized companies the average salargy ranges between $40,000 and $60,000 depending on your experience, degree, etc. At large companies if you become one of the higher leveled administrators their salary ranges anywhere from $70,000 on up to several hundred thousand. It really depends on a bunch of different factors.
