What is FLSA Overtime?

By Anthony Moretti · Updated June 2026

The federal requirement under the Fair Labor Standards Act that non-exempt employees be paid at least 1.5 times their regular rate of pay for all hours worked beyond 40 in a single workweek.

Why FLSA overtime matters for employers

FLSA overtime is calculated on a workweek basis. The workweek is a fixed, regularly recurring 168-hour period (seven consecutive 24-hour periods). The employer designates the workweek and it can begin on any day, but once set it must remain consistent and cannot be changed to avoid overtime obligations. Any hours worked beyond 40 in a single workweek must be compensated at the overtime rate of at least 1.5 times the regular rate of pay. Hours cannot be averaged across workweeks, meaning an employee who works 44 hours one week and 36 hours the next is owed overtime for the four excess hours in the first week, even though the two-week total is 80 hours. The regular rate of pay is the foundation of the overtime calculation. It is not always the same as the hourly rate. The regular rate is calculated by dividing total compensation earned in the workweek by total hours worked. Total compensation includes hourly wages, salary, piece-rate pay, commissions, shift differentials, and most other forms of compensation. Certain payments are excluded from the regular rate, including true gifts, vacation pay, overtime premiums themselves, and discretionary bonuses. The half-time premium for overtime (the extra 0.5x) is added to the regular rate already included in base pay. The most common errors in overtime calculation are: averaging hours across weeks, failing to include all compensation in the regular rate, and misclassifying employees as exempt. Non-exempt employees cannot waive their right to overtime. An employee who agrees in writing to work overtime without additional pay is still legally owed the overtime.

Frequently asked questions

Can overtime be calculated over a two-week pay period instead of per workweek?

No. The FLSA requires overtime to be calculated within each single workweek regardless of pay frequency. You cannot average hours across a bi-weekly pay period. An employee who works 44 hours in week one and 36 in week two is owed overtime for four hours in week one.

What is included in the regular rate for overtime calculation?

The regular rate includes hourly wages, salary allocated to the workweek, piece-rate earnings, commissions earned in the workweek, non-discretionary bonuses, and shift differentials. It excludes discretionary bonuses, gifts, vacation pay, overtime premiums already paid, and certain other statutory exclusions.

Can an employee sign a waiver agreeing not to receive overtime pay?

No. The FLSA right to overtime pay cannot be waived by agreement between employer and employee. Any agreement to forgo overtime is void as against public policy. The employee retains the right to sue for unpaid overtime regardless of any waiver they signed.
