29 C.F.R. § 548.305
(c) The exclusion of one or more additional payments under § 548.3(e) must not affect the overtime compensation of the employee by more than 40 percent of the applicable hourly minimum wage under either section 6(a) of the Act or the state or local law applicable in the jurisdiction in which the employee is employed, whichever is higher, per week on the average for the overtime weeks.
(d) It is not always necessary to make elaborate computations to determine whether the effect of the exclusion of a bonus or other incidental payment on the employee's total compensation will exceed 40 percent of the applicable hourly minimum wage under either section 6(a) of the Act or the state or local law applicable in the jurisdiction in which the employee is employed, whichever is higher, per week on the average. Frequently the addition to regular wages is so small or the number of overtime hours is so limited that under any conceivable circumstances exclusion of the additional payments from the rate used to compute the employee's overtime compensation would not affect the employee's total earnings by more than 40 percent of the applicable hourly minimum wage under either section 6(a) of the Act or the state or local law applicable in the jurisdiction in which the employee is employed, whichever is higher, per week. The determination that this is so may be made by inspection of the payroll records or knowledge of the normal working hours.
(1) Example. An employer has a policy of giving employees who have a perfect attendance record during a 4-week period a bonus of $50. The employee never works more than 50 hours a week. Exclusion of this attendance bonus from the rate of pay used to compute overtime compensation could not affect the employee's total earnings by more than $2.90 per week (i.e., 40 percent of the minimum wage of $7.25, assuming the employee works in a state or locality that does not have a minimum wage that is higher than the minimum wage under the FLSA). 14
14 For a 50-hour week, an employee's bonus would have to exceed $29 a week to affect his overtime compensation by more than $2.90 (i.e., 40 percent of the minimum wage of $7.25). ($30 ÷ 50 hours worked × 10 overtime hours × 0.5).
(f) In order to determine whether the exclusion of a bonus or other incidental payment would affect the total compensation of the employee by not more than 40 percent of the applicable hourly minimum wage under either section 6(a) of the Act or the state or local law applicable in the jurisdiction in which the employee is employed, whichever is higher, per week on the average, a comparison is made between his total compensation computed under the employment agreement and his total compensation computed in accordance with the applicable overtime provisions of the Act.
(1) Example. An employee, who normally would come within the 40-hour provision of section 7(a) of the Act, is paid at piece rates and at one and one-half times the applicable piece rates for work performed during hours in excess of 40 in the workweek. The employee is also paid a bonus, which when apportioned over the bonus period, amounts to $10 a week. He never works more than 50 hours a week. The piece rates could be established as basic rates under the employment agreement and no additional overtime compensation paid on the bonus. The employee's total compensation computed in accordance with the applicable overtime provision of the Act, section 7(g)(1) 15 would be affected by not more than $1 in any week by not paying overtime compensation on the bonus. 16
15 Section 7(g)(1) of the Act provides that overtime compensation may be paid at one and one-half times the applicable piece rate but extra overtime compensation must be properly computed and paid on additional pay required to be included in computing the regular rate. 16 Bonus of $10 divided by fifty hours equals 20 cents an hour. Half of this hourly rate multiplied by ten overtime hours equals $1.
