How Overtime Pay Works: Who Qualifies and How It Is Calculated

The Federal Overtime Rule

The Fair Labor Standards Act (FLSA), enacted in 1938 and administered by the Department of Labor, establishes the federal baseline for overtime pay in the United States. The core requirement is straightforward: non-exempt employees must be paid at least 1.5 times their regular rate of pay for all hours worked beyond 40 in a single workweek. There is no federal requirement for daily overtime, weekend premium pay, or holiday pay — only weekly hours above 40 trigger the obligation.

A workweek is any fixed, regularly recurring period of 168 hours (seven consecutive 24-hour periods). An employer can define the workweek start as any day of the week — Monday, Sunday, Wednesday — but must use the same week consistently and cannot manipulate it to avoid overtime obligations.

Exempt vs. Non-Exempt Employees

The FLSA divides workers into two categories: non-exempt (entitled to overtime) and exempt (not entitled to overtime). Most hourly workers are automatically non-exempt. Salaried workers may or may not be exempt depending on whether they meet both a salary test and a duties test.

The salary basis test: as of 2024 regulatory changes, exempt status generally requires a salary of at least $684 per week ($35,568 per year). Employees paid below this threshold are non-exempt and entitled to overtime regardless of job title or duties. The threshold is periodically updated — always check the current DOL guidance.

The duties test has three primary exemption categories:

• Executive exemption: The employee's primary duty is management of the enterprise or a department, they regularly direct two or more employees, and they have genuine authority over hiring and firing decisions.
• Administrative exemption: The employee performs office or non-manual work directly related to management or general business operations, with a primary duty that includes the exercise of discretion and independent judgment on significant matters.
• Professional exemption: Work requiring advanced knowledge in a field of science or learning, customarily acquired through a prolonged course of specialized intellectual instruction — typically a four-year degree in the specific field.

Additional Exemptions

Beyond the big three, the FLSA contains numerous additional exemptions applicable to specific industries and roles:

• Outside sales employees: Those who primarily make sales away from the employer's place of business are exempt regardless of salary level.
• Computer professionals: Certain high-paid IT workers earning at least $27.63 per hour may qualify for the computer employee exemption.
• Highly compensated employees (HCE): Workers earning at least $107,432 annually qualify for a streamlined HCE exemption if they customarily perform at least one executive, administrative, or professional duty.
• Agricultural workers: Subject to a complex set of partial exemptions depending on employer size and the nature of the agricultural work.

Calculating the Regular Rate of Pay

Overtime is calculated on the regular rate of pay, which is not necessarily the same as the hourly wage. The regular rate is calculated by dividing total earnings in the workweek by total hours worked. This calculation must include most forms of compensation received in that workweek:

• Regular hourly wages or salary allocated to the week.
• Shift differentials (extra pay for working nights or weekends).
• Non-discretionary bonuses (production bonuses, attendance bonuses, or any bonus that employees have a legal right to expect).
• Commissions earned in the week (though there are specific calculation rules for commission-based work).

Excluded from the regular rate: true discretionary bonuses (holiday gifts not announced in advance), overtime premium pay itself, reimbursements for expenses, and certain benefit plan contributions. An employee who earns $20/hour in regular wages plus a $50 weekly production bonus and worked 48 hours has a regular rate of ($20 x 48 + $50) / 48 = $21.04/hour. The overtime premium owed for the 8 overtime hours is 0.5 x $21.04 x 8 = $84.16.

State Overtime Laws: Additional Protections

Many states have enacted overtime rules that provide greater protections than the FLSA. California is the most notable example: California requires overtime (1.5x) for hours worked beyond 8 in a single day (not just 40 in a week) and double-time pay for hours worked beyond 12 in a day or beyond 8 hours on the seventh consecutive day in a workweek. Alaska and Nevada also have daily overtime requirements.

When state law provides greater benefits than federal law, the state standard applies. California's rules mean that an employee who works twelve 6.5-hour days in a two-week period owes no federal overtime (only 39 hours in each 7-day period) but owes California overtime because each day's 6.5 hours exceeded 6 hours — demonstrating why state law is critically important.

Misclassification: A Major Source of Wage Theft

One of the most common forms of wage theft is misclassification — labeling employees as exempt (salaried) or as independent contractors when they legally qualify as non-exempt employees entitled to overtime. The Department of Labor and courts look at economic reality, not just job titles or contract labels, when determining classification.

If your employer calls you a manager but your actual duties are primarily performing the same tasks as non-exempt coworkers, a court may find you were misclassified and owe back overtime. Signs of potential misclassification include: being paid a salary just above the exemption threshold for a role that involves little genuine management or independent judgment, being required to track and be docked for time off (suggesting a non-exempt classification), or being classified as an independent contractor while working under close employer direction and supervision.

Recovering Unpaid Overtime

If you believe you are owed unpaid overtime, you have several options. You can file a complaint with the Department of Labor's Wage and Hour Division, which investigates violations at no cost and can recover back wages on your behalf. Alternatively, you can file a private lawsuit, which may entitle you to: unpaid overtime, an equal amount in liquidated damages (doubling the recovery), attorney fees paid by the employer, and up to two years of back pay (three years for willful violations).

The statute of limitations for FLSA claims is two years for ordinary violations and three years for willful violations — meaning you can potentially recover unpaid overtime going back two or three years, not just the most recent incidents. Collective actions (similar to class actions for wage claims) allow groups of misclassified workers to sue together, making claims economically viable even when individual amounts are modest.
