The salary of a security guard can vary depending on a number of factors, including the type of job they are doing, their level of experience, and the location in which they work. In the United States, the median annual salary for a security guard is $29,660. However, some security guards may earn more or less than this amount depending on their job duties and other factors. For example, a security guard working in a high-security government facility may earn a higher salary than one working in a retail store. Similarly, a security guard with several years of experience may earn a higher salary than a guard who is just starting out in the field.
