Introduction

Overtime pay is one of the most consequential — and most misunderstood — aspects of employment law in the United States. Every year, the Department of Labor recovers hundreds of millions of dollars in back wages from employers who miscalculate overtime, misclassify employees, or simply ignore the rules.

For employees, understanding overtime means knowing when you are entitled to extra pay and how much that pay should be. For employers, it means compliance with federal and state law, avoiding costly lawsuits, and building accurate payroll systems.

At its core, overtime pay is straightforward: when a non-exempt employee works more than 40 hours in a workweek, the employer must pay at least 1.5 times the employee's regular rate for every hour beyond 40. This "time and a half" requirement is the foundation of the Fair Labor Standards Act (FLSA), the federal law that has governed wages and hours in the United States since 1938.

This guide covers everything you need to know: the FLSA framework, how to calculate overtime step by step, the difference between exempt and non-exempt employees, state-specific rules that go beyond federal requirements, special scenarios involving multiple pay rates and bonuses, and employer obligations and penalties.

The FLSA and the 40-Hour Workweek Rule

The Fair Labor Standards Act (FLSA) is the federal law that establishes minimum wage, overtime pay, recordkeeping, and youth employment standards in the United States. Enacted in 1938, it covers most private-sector employees and federal, state, and local government workers.

The Core Rule

The FLSA overtime provision is found in Section 207(a):

Non-exempt employees must receive overtime pay at a rate of not less than 1.5 times their regular rate of pay for all hours worked over 40 in a workweek.

Key definitions within this rule:

Workweek: A fixed, recurring period of 168 consecutive hours (seven consecutive 24-hour periods). The employer defines when the workweek begins. It does not need to align with the calendar week.
Hours worked: All time an employee is required to be on the employer's premises, on duty, or at a prescribed workplace. This includes short breaks (under 20 minutes), training time (if required by the employer), and travel time during the workday.
Regular rate of pay: The employee's total remuneration for employment divided by the total hours worked. This is not always the same as the hourly wage — it can include non-discretionary bonuses, shift differentials, and commissions.

What the FLSA Does Not Require

The FLSA does not require overtime pay for:

Work on weekends, holidays, or regular days of rest (unless those hours push the total past 40 in the workweek)
Daily overtime (working more than 8 hours in a single day — this is a state law matter)
Double time pay (this is a state or contractual provision, not a federal requirement)
Overtime for salaried employees who meet the exemption criteria

Who Is Covered

The FLSA applies through two types of coverage:

Enterprise coverage: Businesses with at least two employees and annual gross revenue of $500,000 or more. Also covers hospitals, schools, and government agencies regardless of revenue.
Individual coverage: Employees engaged in interstate commerce or the production of goods for interstate commerce, regardless of employer size.

In practice, this covers the vast majority of American workers. Approximately 143 million workers are protected by the FLSA.

How to Calculate Overtime Pay

The Basic Formula

Overtime Pay = Overtime Hours x (Regular Hourly Rate x 1.5)

Total Weekly Pay = (Regular Hours x Regular Rate) + (Overtime Hours x Overtime Rate)

Where:

Regular hours = hours worked up to 40 in the workweek
Overtime hours = hours worked beyond 40
Regular rate = base hourly pay (or calculated hourly equivalent for salaried workers)
Overtime rate = regular rate x 1.5

Example 1: Hourly Employee

Sarah earns $20 per hour and works 48 hours in one workweek.

Regular pay: 40 hours x $20 = $800
Overtime hours: 48 - 40 = 8 hours
Overtime rate: $20 x 1.5 = $30
Overtime pay: 8 hours x $30 = $240
Total weekly pay: $800 + $240 = $1,040

Without overtime, Sarah would have earned 48 x $20 = $960. The overtime premium adds $80 to her paycheck.

Example 2: Salaried Non-Exempt Employee

Marcus is a salaried non-exempt employee earning $960 per week. He works 50 hours this week.

First, calculate his regular hourly rate: $960 / 40 = $24 per hour

Regular pay: $960 (his salary covers the first 40 hours)
Overtime hours: 50 - 40 = 10 hours
Overtime rate: $24 x 1.5 = $36
Overtime pay: 10 x $36 = $360
Total weekly pay: $960 + $360 = $1,320

Example 3: Converting Annual Salary to Overtime Rate

Jessica earns $52,000 per year and is classified as non-exempt. She works 45 hours this week.

Weekly salary: $52,000 / 52 = $1,000
Regular hourly rate: $1,000 / 40 = $25
Overtime rate: $25 x 1.5 = $37.50
Overtime pay: 5 hours x $37.50 = $187.50
Total weekly pay: $1,000 + $187.50 = $1,187.50

Time and a Half Explained

"Time and a half" is the colloquial term for the FLSA's minimum overtime rate of 1.5 times the regular rate. The phrase captures the calculation precisely: for every overtime hour, you earn your regular hourly rate plus an additional half of that rate.

Quick Reference Table

Regular Hourly Rate	Time and a Half Rate	OT Pay for 5 Extra Hours
$12.00	$18.00	$90.00
$15.00	$22.50	$112.50
$18.00	$27.00	$135.00
$20.00	$30.00	$150.00
$25.00	$37.50	$187.50
$30.00	$45.00	$225.00
$35.00	$52.50	$262.50
$40.00	$60.00	$300.00
$50.00	$75.00	$375.00

Why 1.5x?

The 1.5x multiplier was established as a compromise during the New Deal era. Legislators wanted a rate high enough to discourage employers from overworking employees (making it cheaper to hire additional workers) but not so high as to cripple businesses during the Great Depression. The rate has remained unchanged since the FLSA's passage in 1938.

Some union contracts and state laws require higher multipliers for specific circumstances. California, for instance, mandates double time (2x) after 12 hours in a single day and for hours worked beyond 8 on the seventh consecutive day of work.

Double Time: When It Applies

Double time means the employee earns twice their regular hourly rate. The FLSA does not require double time — it is strictly a state law or contractual provision.

California Double Time Rules

California has the most comprehensive daily overtime and double-time requirements in the nation:

Over 8 hours in a day: Time and a half (1.5x) for hours 9 through 12
Over 12 hours in a day: Double time (2x) for all hours beyond 12
Seventh consecutive day: Time and a half for the first 8 hours; double time for all hours beyond 8

California Double Time Example

A California employee earning $24 per hour works a 14-hour shift.

First 8 hours: 8 x $24 = $192 (regular rate)
Hours 9–12: 4 x $36 = $144 (time and a half)
Hours 13–14: 2 x $48 = $96 (double time)
Total daily pay: $192 + $144 + $96 = $432

Compare this to the same shift under federal law only: 14 hours at the regular rate of $24 = $336. California's daily overtime rules add $96 to the employee's pay for that single day.

Other States with Double Time

Very few states mandate double time. As of 2025, California is the only state with a statutory daily double-time requirement for all non-exempt employees. Some union collective bargaining agreements include double-time provisions, and certain industries (notably construction and maritime) may have contractual double-time terms.

Exempt vs Non-Exempt: The 3-Part Test

The most critical classification in overtime law is the distinction between exempt and non-exempt employees. Exempt employees are not entitled to overtime pay. Non-exempt employees are.

To be classified as exempt from FLSA overtime, an employee must satisfy all three parts of the exemption test:

Part 1: Salary Basis Test

The employee must be paid on a salary basis, meaning they receive a predetermined, fixed amount of compensation each pay period that is not subject to reduction based on the quality or quantity of work. An employer cannot dock an exempt employee's pay for working fewer hours in a particular week (with limited exceptions for full-day absences).

Part 2: Salary Level Test

The employee's salary must meet or exceed the minimum threshold set by the Department of Labor. As of 2025, this threshold is $58,656 per year ($1,128 per week). Employees earning less than this amount are automatically non-exempt, regardless of their job duties.

Part 3: Duties Test

The employee's primary duty must fall into one of the recognized exempt categories:

Executive exemption: The employee's primary duty is managing the enterprise or a recognized department, they regularly direct the work of at least two full-time employees, and they have genuine authority to hire, fire, or make recommendations that carry significant weight.

Administrative exemption: The employee's primary duty is office or non-manual work directly related to management or general business operations, and they exercise discretion and independent judgment on matters of significance. This is the most commonly litigated exemption.

Professional exemption: The employee's primary duty requires advanced knowledge in a field of science or learning customarily acquired through prolonged, specialized education (learned professional), or the employee's primary duty requires invention, imagination, originality, or talent in a recognized creative field (creative professional).

Computer employee exemption: The employee works as a computer systems analyst, programmer, software engineer, or similar worker and earns at least $684 per week (or $27.63 per hour). Their primary duties must involve systems analysis, programming, software design, or similar high-level computer work.

Outside sales exemption: The employee's primary duty is making sales or obtaining contracts, and they customarily work away from the employer's place of business. There is no minimum salary requirement for outside sales employees.

Job Title Examples

Typically Exempt	Typically Non-Exempt
Department manager	Administrative assistant
Software engineer ($100K+)	Data entry clerk
Marketing director	Marketing coordinator
Financial analyst	Bookkeeper
HR manager	HR assistant
Licensed attorney	Paralegal
Physician	Medical technician
CPA	Accounting clerk
IT architect	Help desk technician

Important: Job title alone does not determine exempt status. An employee titled "Manager" who spends 90% of their time performing non-managerial work and earns $45,000 per year is almost certainly non-exempt. The duties test looks at what the employee actually does, not what their business card says.

2025 FLSA Salary Threshold: $58,656

The salary threshold for the executive, administrative, and professional exemptions was updated as part of a phased rulemaking process by the Department of Labor.

Timeline of Recent Changes

Effective Date	Weekly Threshold	Annual Threshold
Before July 1, 2024	$684	$35,568
July 1, 2024	$844	$43,888
January 1, 2025	$1,128	$58,656

What the 2025 Threshold Means

Any salaried employee earning less than $58,656 per year ($1,128 per week) is automatically non-exempt and must receive overtime pay for hours worked over 40 per week, regardless of their job duties. This change extended overtime protection to an estimated 4 million additional workers.

Highly Compensated Employee (HCE) Threshold

The FLSA also has a streamlined exemption test for highly compensated employees. As of 2025, employees earning at least $151,164 per year are exempt if they customarily perform at least one of the duties of an exempt executive, administrative, or professional employee. This is a lower duties bar than the standard test — the employee only needs to satisfy one duty element, not all of them.

Automatic Updates

The 2024 rule includes a mechanism for automatic updates to the salary threshold every three years based on current wage data, ensuring the threshold keeps pace with salary growth.

State-Specific Overtime Rules

Federal FLSA rules set the floor, not the ceiling. Many states have overtime laws that provide greater protections. When federal and state laws conflict, the employee is entitled to whichever provision is more favorable.

California

California has the most employee-friendly overtime laws in the country:

Daily overtime: Time and a half for hours worked over 8 in a workday
Daily double time: 2x pay for hours worked over 12 in a workday
Seventh consecutive day: Time and a half for the first 8 hours; double time after 8 hours
Alternative workweek: Employers can establish a 10-hour/4-day schedule by employee vote, which eliminates daily overtime for hours 9 and 10 but preserves it beyond 10 hours

California employees can receive both daily and weekly overtime, but hours are not double-counted. The state also has a higher salary threshold for exemption than the federal level: $66,560 per year in 2024 (based on two times the state minimum wage).

Alaska

Alaska requires overtime pay for hours worked over 8 in a single day, in addition to the federal 40-hour weekly rule. However, Alaska does not have a double-time provision. Employees in Alaska can earn daily overtime even if their total weekly hours do not exceed 40.

Colorado

Colorado's Overtime and Minimum Pay Standards (COMPS) Order requires:

Time and a half for hours over 40 in a workweek (matching federal law)
Time and a half for hours over 12 in a workday
Time and a half for 12 or more consecutive hours worked regardless of start/end times

Colorado also has a higher salary exemption threshold than the federal standard.

Other Notable State Provisions

State	Key Overtime Provision
Nevada	Daily overtime after 8 hours (if hourly rate is less than 1.5x minimum wage)
Oregon	Manufacturing employees: daily overtime after 10 hours
Washington	Follows federal FLSA but higher minimum wage ($16.28 in 2024) raises the effective OT rate
New York	Follows federal FLSA; NYC has additional wage theft protections
Massachusetts	Follows federal FLSA; time and a half for Sunday/holiday retail work (being phased out)

Always check your specific state's Department of Labor website for the most current rules, as overtime legislation changes frequently.

Special Scenarios

Multiple Pay Rates (Weighted Average)

Some employees work at different pay rates during the same workweek — for example, a construction worker who earns $25/hour for carpentry and $30/hour for electrical work. When overtime occurs, the regular rate must be calculated as a weighted average.

Weighted Regular Rate = Total Straight-Time Earnings / Total Hours Worked

Example: An employee works 25 hours at $20/hour and 20 hours at $25/hour in one week (45 total hours).

Straight-time earnings: (25 x $20) + (20 x $25) = $500 + $500 = $1,000
Weighted regular rate: $1,000 / 45 = $22.22
Overtime premium: $22.22 x 0.5 = $11.11 (the half-time premium for each OT hour)
Total pay: $1,000 + (5 x $11.11) = $1,000 + $55.56 = $1,055.56

Note: The overtime premium is only the additional 0.5x because the straight-time earnings already include payment at the regular rate for all 45 hours.

Non-Discretionary Bonuses

Non-discretionary bonuses (those announced in advance as an incentive, such as production bonuses or attendance bonuses) must be included in the regular rate calculation. Discretionary bonuses (such as a surprise holiday bonus) do not need to be included.

Example: An employee earns $20/hour, works 50 hours, and receives a $100 production bonus for the week.

Straight-time earnings: 50 x $20 = $1,000
Total compensation: $1,000 + $100 = $1,100
Regular rate: $1,100 / 50 = $22.00
Overtime premium owed: 10 overtime hours x ($22.00 x 0.5) = $110.00
Total pay: $1,100 + $110 = $1,210.00

Without including the bonus in the regular rate, the overtime would have been calculated on $20/hour, shortchanging the employee.

Fluctuating Workweek Method

Under the fluctuating workweek (FWW) method, a salaried non-exempt employee receives a fixed salary intended to cover all straight-time hours, regardless of how many hours are worked. The employer only owes an additional half-time premium (0.5x) for each overtime hour.

Requirements for the FWW method:

Employee's hours must genuinely fluctuate week to week
Employee receives a fixed salary regardless of hours
The salary must cover at least minimum wage for all hours worked
There is a clear mutual understanding that the salary covers all straight-time hours

Example: An employee receives a $900 fixed weekly salary and works 50 hours one week.

Regular rate: $900 / 50 = $18.00
Half-time premium: $18.00 x 0.5 = $9.00
Overtime premium: 10 hours x $9.00 = $90.00
Total pay: $900 + $90 = $990.00

This method results in a lower overtime cost for the employer compared to the standard calculation, which is why strict conditions must be met.

Employer Obligations and Penalties

Recordkeeping Requirements

The FLSA requires employers to maintain accurate records for each non-exempt employee, including:

Full name, address, and Social Security number
Hour and day when the workweek begins
Total hours worked each workday and each workweek
Regular hourly rate for any week in which overtime is worked
Total overtime pay for the workweek
Total wages paid each pay period
Date of payment and pay period covered

Records must be kept for at least three years for payroll records and two years for supplementary records (time cards, wage rate tables, work schedules).

Penalties for Violations

Employers who violate the FLSA overtime provisions face significant consequences:

Back wages: Employers must pay the full amount of unpaid overtime, going back up to two years (or three years for willful violations)
Liquidated damages: In most cases, employees are entitled to an equal amount in liquidated damages — effectively doubling the back-pay award
Civil penalties: Up to $2,374 per violation for repeated or willful violations (adjusted periodically for inflation)
Criminal penalties: Willful violations can result in fines up to $10,000 and imprisonment for repeat offenders
Attorney's fees: Prevailing employees are entitled to recover their legal costs

Common Employer Mistakes

Misclassifying employees as exempt when they do not meet all three parts of the exemption test
Not paying for "off the clock" work such as pre-shift preparation, post-shift cleanup, or answering emails at home
Averaging hours across two workweeks — each workweek stands alone under the FLSA
Offering comp time instead of overtime pay — private-sector employers generally cannot substitute compensatory time off for overtime pay
Excluding non-discretionary bonuses from the regular rate calculation
Using job titles rather than actual duties to determine exempt status

Frequently Asked Questions

Can my employer force me to work overtime?

Yes. The FLSA does not limit the number of hours an adult employee can work. An employer can require overtime and can discipline or terminate an employee who refuses, as long as the overtime hours are properly compensated. Some state laws and union contracts may restrict mandatory overtime in specific industries (healthcare being the most common).

Do salaried employees get overtime?

It depends on whether the employee is exempt or non-exempt. A salaried employee who earns below the salary threshold ($58,656 as of 2025) is automatically non-exempt and must receive overtime pay. A salaried employee above the threshold may still be non-exempt if their duties do not satisfy one of the recognized exemption categories. Salary alone does not determine overtime eligibility — both the salary level and the duties test must be met for an exemption to apply.

Is overtime calculated daily or weekly?

Under federal law, overtime is calculated on a weekly basis only. The 40-hour threshold applies to the workweek, not the workday. An employee who works 12 hours on Monday and 4 hours on each of Tuesday through Friday (32 hours total for the remaining days) has worked 44 hours for the week and is owed 4 hours of overtime. However, some states — California, Alaska, Nevada, and Colorado — have daily overtime rules. In California, any hours over 8 in a single day trigger overtime regardless of total weekly hours.

What counts as "hours worked" for overtime?

Hours worked includes all time the employee is required or permitted to work, whether on or off the employer's premises. This includes: required training, mandatory meetings, time spent putting on protective equipment (donning and doffing), on-call time when the employee's movements are significantly restricted, travel between job sites during the workday, and short rest breaks of 20 minutes or less. It does not include: bona fide meal periods of 30 minutes or more (if the employee is fully relieved of duties), commuting time from home to the regular work location, or time spent on purely voluntary training outside regular hours.

Can I waive my right to overtime pay?

No. An employee cannot waive their right to overtime pay under the FLSA, even voluntarily. Any agreement between employer and employee to work for straight time only, regardless of hours, is not valid. This is a common misconception — employees sometimes agree to a "flat salary for all hours" arrangement, believing it is legal. It is not. The FLSA overtime requirement is a statutory protection that cannot be bargained away.

How does overtime work for tipped employees?

Tipped employees are entitled to overtime pay. The overtime rate is calculated on the full minimum wage, not the reduced tipped wage. If a tipped employee's regular rate (including tips) is $15/hour and they work 45 hours in a week, their overtime rate is $15 x 1.5 = $22.50 for each of the 5 overtime hours. The employer must ensure that the tip credit does not reduce the overtime rate below 1.5 times the full federal minimum wage.
