Frequently Asked Questions
How do you calculate overtime pay under the FLSA?
Overtime pay is calculated by first determining your 'regular rate of pay' for the workweek (total straight-time earnings, including things like non-discretionary bonuses and shift differentials, divided by total hours worked), then paying an overtime premium of 0.5 times that regular rate for each hour worked beyond 40 in the workweek, on top of straight-time pay for those hours. For example, an hourly employee earning $20/hour who works 45 hours and receives a $50 bonus that week would have a regular rate of about $21.11/hour, resulting in roughly $52.78 in overtime premium for the 5 overtime hours.
Who qualifies for overtime pay under federal law?
Most hourly workers are 'non-exempt' and entitled to overtime, while salaried employees may be classified as 'exempt' from overtime only if they meet all three federal tests: being paid on a salary basis, meeting a minimum salary threshold set by the Department of Labor, and having primary job duties that fall into an exempt category such as executive, administrative, or professional work. A job title alone doesn't determine exempt status — someone called a 'manager' who spends most of their time doing the same work as the people they supervise may still legally be non-exempt and owed overtime.
What counts as the 'regular rate of pay' for overtime calculations?
The regular rate of pay is broader than just your base hourly wage — it generally must include most additional compensation earned during the workweek, such as shift differentials, non-discretionary bonuses, on-call pay, and piece-rate earnings, divided by total hours worked. It generally excludes gifts, truly discretionary bonuses, vacation pay, and contributions to certain bona fide benefit plans, so accurately calculating overtime requires including all the applicable extra pay before dividing by hours worked.
Can an employer average my hours across two weeks to avoid paying overtime?
No — under the FLSA, overtime must be calculated on a single-workweek basis, and hours cannot be averaged across two or more weeks to avoid the overtime obligation. For example, if you work 30 hours one week and 50 hours the next, your employer owes overtime for the 10 hours over 40 in the second week, even though your two-week average works out to exactly 40 hours per week.
