A
pay scale (also known as a
salary structure) is a system that determines how much an
employee is to be paid as a
wage or
salary, based on one or more factors such as the employee's level, rank or status within the employer's organization, the length of time that the employee has been employed, and the difficulty of the specific work performed. Examples of pay scales include
U.S. uniformed services pay grades, the salary grades by which United States military personnel are paid, and the
General Schedule, the salary grades by which United States white-collar civil service personnel are paid. Private employers use salary structures with grades (including minimums, midpoints and maximums) to define the ranges of pay available to employees in each grade/range.
