Overtime Pay: Rules, Calculations, and Your Rights

Updated March 2026 · By the PayrollCalcs Team

Overtime pay is one of the most important protections in American labor law, yet it remains widely misunderstood by both employers and employees. The Fair Labor Standards Act requires most employers to pay eligible workers at least one and a half times their regular rate for hours worked beyond 40 in a workweek. Understanding the rules around overtime eligibility, calculation methods, and exemption criteria can mean the difference between thousands of dollars earned or left on the table.

Federal Overtime Rules Under the FLSA

The Fair Labor Standards Act establishes the baseline overtime requirement: non-exempt employees must receive at least 1.5 times their regular rate of pay for all hours worked beyond 40 in a single workweek. A workweek is a fixed, recurring period of 168 hours or seven consecutive 24-hour periods, and employers cannot average hours across multiple weeks to avoid overtime.

The FLSA applies to most private employers with annual gross revenue of at least $500,000 and to all employees of hospitals, schools, and government agencies regardless of revenue. Individual employees are also covered if they engage in interstate commerce or produce goods for interstate commerce.

Overtime threshold: 40 hours per workweek
Minimum overtime rate: 1.5 times regular rate
Workweek cannot be averaged or manipulated to avoid overtime
Applies to most employers with revenue over $500,000

Pro tip: Your employer defines the workweek start day, which does not have to be Monday. Know when your workweek starts so you can track your overtime hours accurately.

Exempt vs. Non-Exempt Employees

Not all employees qualify for overtime pay. The FLSA defines specific exemptions based on job duties and salary level. The most common are the executive, administrative, and professional exemptions, which require that employees earn at least $684 per week on a salary basis and perform certain high-level duties.

Job title alone does not determine exemption status. A manager who spends most of their time performing non-managerial tasks may still be non-exempt. The duties test examines the primary work actually performed, not the title on a business card or job description.

Executive exemption: manages an enterprise or department, directs two or more employees
Administrative exemption: performs office work related to management or business operations
Professional exemption: requires advanced knowledge or creative ability
Computer employee exemption: applies to certain IT professionals earning at least $684 per week
Highly compensated employee exemption: total annual compensation of $107,432 or more

Pro tip: If you suspect you are incorrectly classified as exempt, consult your state labor board or a labor attorney. Misclassification claims can recover up to three years of back overtime pay.

How Overtime Pay Is Calculated

For hourly employees, overtime calculation is straightforward: multiply the regular hourly rate by 1.5 for each hour beyond 40. If you earn $20 per hour and work 48 hours, you receive $800 for the first 40 hours plus $240 for 8 overtime hours, totaling $1,040.

For employees who receive non-discretionary bonuses, commissions, or shift differentials, these amounts must be factored into the regular rate before calculating overtime. The regular rate includes all compensation for employment except gifts, vacation pay, and certain benefit plan contributions.

Regular rate includes base pay, non-discretionary bonuses, and shift differentials
Overtime rate = regular rate multiplied by 1.5
Some states require daily overtime after 8 hours (California, Alaska, Nevada, Colorado)
Double time (2x) may apply in certain states for extended hours or seventh consecutive workday

Pro tip: Always verify that your overtime rate includes non-discretionary bonuses. Some employers incorrectly calculate overtime using base hourly rate alone, which underpays you.

State Overtime Laws That Go Beyond Federal

Several states provide overtime protections that exceed the FLSA. California requires overtime after 8 hours in a single day and double time after 12 hours. Alaska and Nevada also mandate daily overtime. Colorado requires overtime after 12 hours in a day or 40 hours in a week.

When state and federal laws differ, the law most favorable to the employee applies. This means workers in states with daily overtime rules may earn overtime even when their weekly total does not exceed 40 hours. Always check your specific state labor laws.

California: 1.5x after 8 hours daily, 2x after 12 hours daily
Alaska: 1.5x after 8 hours daily for most employees
Colorado: 1.5x after 12 hours daily or 40 hours weekly
Nevada: 1.5x after 8 hours daily if hourly rate is less than 1.5 times minimum wage

Pro tip: If you work in multiple states, overtime rules are determined by where the work is physically performed, not where the employer is headquartered.

Maximizing and Protecting Your Overtime Earnings

To protect your overtime earnings, maintain detailed personal records of all hours worked including start times, end times, and meal breaks. While employers are required to keep time records, having your own documentation provides essential backup if disputes arise.

Be aware of common employer practices that may violate overtime rules. These include rounding time entries in the employer favor consistently, requiring off-the-clock work such as setup, cleanup, or email checking, and automatically deducting lunch breaks even when employees work through them.

Keep a personal log of your daily hours worked
Report all hours accurately, including pre-shift and post-shift work
Document any requests to work off the clock
Understand your rights under both federal and state overtime laws
File a complaint with the Department of Labor if you believe you are being shorted

Pro tip: Wage theft through unpaid overtime is the most common form of theft in the United States. If you consistently work over 40 hours without overtime pay, investigate your exemption status.

Frequently Asked Questions

Can my employer force me to work overtime?

In most states, yes. There is no federal law limiting the number of hours an employer can require an adult employee to work. However, the employer must pay overtime rates for all hours over 40 per week for non-exempt employees.

Does salary automatically mean I am exempt from overtime?

No. Being paid a salary is only one requirement for overtime exemption. You must also meet the duties test for executive, administrative, or professional exemptions and earn at least $684 per week.

Is compensatory time off legal instead of overtime pay?

Comp time in lieu of overtime pay is generally illegal for private employers under the FLSA. Public sector employers may offer comp time under specific conditions, but private employers must pay overtime in wages.

Do part-time employees get overtime?

Part-time employees are entitled to overtime if they work more than 40 hours in a workweek. Part-time status does not affect overtime eligibility under the FLSA.

How far back can I claim unpaid overtime?

Under the FLSA, you can recover unpaid overtime for up to two years, or three years if the violation was willful. State laws may provide longer recovery periods.
