§ 778.114 Fluctuating Workweek Method of Computing Overtime.
(a) An employer may use the fluctuating workweek method to properly compute overtime compensation based on the regular rate for a nonexempt employee under the following circumstances:
(1) The employee works hours that fluctuate from week to week;
(2) The employee receives a fixed salary that does not vary with the number of hours worked in the workweek, whether few or many;
(3) The amount of the employee's fixed salary is sufficient to provide compensation to the employee at a rate not less than the applicable minimum wage rate for every hour worked in those workweeks in which the number of hours the employee works is greatest;
(4) The employee and the employer have a clear and mutual understanding that the fixed salary is compensation (apart from overtime premiums and any bonuses, premium payments, commissions, hazard pay, or other additional pay of any kind not excludable from the regular rate under section 7(e)(l) through (8) of the Act) for the total hours worked each workweek regardless of the number of hours, although the clear and mutual understanding does not need to extend to the specific method used to calculate overtime pay; and
(5) The employee receives overtime compensation, in addition to such fixed salary and any bonuses, premium payments, commissions, hazard pay, and additional pay of any kind, for all overtime hours worked at a rate of not less than one-half the employee's regular rate of pay for that workweek. Since the salary is fixed, the regular rate of the employee will vary from week to week and is determined by dividing the amount of the salary and any non-excludable additional pay received each workweek by the number of hours worked in the workweek. Payment for overtime hours at not less than one-half such rate satisfies the overtime pay requirement because such hours have already been compensated at the straight time rate by payment of the fixed salary and non-excludable additional pay. Payment of any bonuses, premium payments, commissions, hazard pay, and additional pay of any kind is compatible with the fluctuating workweek method of overtime payment, and such payments must be included in the calculation of the regular rate unless excludable under section 7(e)(1) through (8) of the Act.
