How to Calculate Overtime Pay: A US Employer Guide

Are you sure every one of your employees is being paid the overtime they are legally owed?

One misclassified worker or one miscalculated workweek can turn into back wages, double damages, and a Department of Labor audit. Under the Fair Labor Standards Act (FLSA), most non-exempt employees must earn 1.5 times their regular rate for every hour past 40 in a workweek, yet the exact rules shift by state and change from year to year.

This guide breaks down how overtime pay works in the United States, how to calculate it accurately, what the new federal overtime tax deduction means for 2026, and how to stay compliant as the laws keep moving.

What is overtime pay, and who qualifies for it in the US?

Overtime pay is the premium wage US employers owe non-exempt employees for hours worked beyond 40 in a single workweek, set by the FLSA at no less than 1.5 times the employee's regular rate of pay. Only non-exempt employees qualify; salaried staff who meet a salary and job-duties test are exempt and are not owed overtime.

Overtime sits alongside your other pay obligations, from base wages to paid time off, so getting the classification right is the foundation of every accurate paycheck.

Before you can calculate a single hour, you need to know exactly where the exempt line falls.

What is the difference between exempt and non-exempt employees?

Non-exempt employees are entitled to overtime; exempt employees are not. To be exempt, a worker must be paid on a salary basis, earn at least the federal salary threshold, and perform qualifying job duties. Anyone who fails any part of that test is non-exempt and must receive overtime.

The FLSA recognizes a limited set of white-collar exemption categories:

• Executive: employees who manage the business or a department and direct at least two full-time staff.
• Administrative: office or non-manual roles tied to business operations that use independent judgment.
• Professional: roles requiring advanced knowledge, such as lawyers, accountants, and engineers.
• Outside sales: employees who regularly work away from the employer's place of business making sales.
• Certain computer employees: specific IT roles that meet the salary or hourly pay test.

If a role does not clearly fit one of these categories and meet the pay test, treat the worker as non-exempt. The same caution applies to a misclassified 1099 contractor, which can trigger the same liability.

Once you know who qualifies, the next building block is defining the period the 40-hour limit applies to.

How is a workweek defined for overtime?

A workweek is any fixed, recurring period of 168 hours, or seven consecutive 24-hour days. It can begin on any day and hour you choose, but it must stay consistent. Overtime is always calculated per workweek, never averaged across two weeks or across a pay period.

That distinction matters most on a biweekly pay period, where each of the two workweeks is still measured on its own.

With eligibility and the workweek settled, you can turn to the laws that set the rates.

Which federal and state laws govern overtime pay?

Two layers of law govern overtime pay in the US. The FLSA sets the federal floor that applies nationwide, and individual states can add stronger protections on top of it. When federal and state rules differ, you must follow whichever one is more generous to the employee.

Start with the federal baseline.

What does the Fair Labor Standards Act (FLSA) require?

The FLSA requires 1.5 times the regular rate for hours over 40 a week, sets recordkeeping standards, and defines who is exempt. As of July 2026, the federal salary threshold for the executive, administrative, and professional exemption is $684 per week ($35,568 per year), and the highly compensated employee threshold is $107,432 per year.

A 2024 rule that would have raised these thresholds was struck down by a federal court in Texas in November 2024, which reverted the limits to their 2019 levels, and no replacement rule has taken effect since. These salary limits are separate from the employer payroll taxes you owe on every wage.

Federal law is only the starting point, because many states set the bar higher.

How do state overtime laws change the rules?

Many states set a higher salary threshold for exemption, and some require daily overtime rather than only weekly. You must apply whichever standard gives the employee more pay. The table below shows the 2026 thresholds that sit above the federal minimum.

Here is how the salary thresholds compare for 2026:

State minimum wages drive several of these figures, so they change most years. Always confirm the current number with your state labor department before you run payroll.

Some states also require daily overtime, which federal law does not. The most common examples:

• California: 1.5 times pay for hours 8 to 12 in a day, 2 times pay beyond 12 hours, plus overtime on the seventh consecutive workday.
• Alaska: 1.5 times pay for hours worked over 8 in a day, on top of the weekly rule.
• Colorado: 1.5 times pay for hours worked over 12 in a single day.
• Nevada: daily overtime after 8 hours for employees earning below 1.5 times the state minimum wage.

Because state rules stack on top of federal law, a multi-state team can face several overtime standards at once, which is where accurate payroll administration becomes non-negotiable.

With the rules mapped, here is how to run the numbers.

How do you calculate overtime pay step by step?

To calculate overtime pay, confirm the employee is non-exempt, set the workweek, find the regular rate including bonuses and commissions, then pay 1.5 times that rate for every hour over 40. The regular rate, not the base wage, is the number most employers get wrong.

Follow these five steps for a compliant calculation:

1. Confirm non-exempt status: verify the employee fails the exemption test and is owed overtime.
2. Fix the workweek: choose a consistent 168-hour period and measure hours within it.
3. Find the regular rate: divide total weekly pay, including nondiscretionary bonuses and commissions, by total hours worked.
4. Apply the multiplier: pay 1.5 times the regular rate for each hour over 40, plus any higher state daily rate.
5. Document everything: keep time records and pay calculations for at least three years.

Steps three and four are where the detail lives, so the sections below work through each with a real example.

How do you determine the regular rate of pay?

The regular rate is the employee's actual hourly earnings for the week, and it must include base pay plus most bonuses, commissions, shift differentials, and merit increases. For a salaried non-exempt worker, divide the weekly salary by the hours it is meant to cover.

A quick example shows the math:

• Weekly salary: $800
• Hours worked: 45
• Regular rate: $800 divided by 45 equals $17.78 per hour

Because bonuses and commissions raise the regular rate, leaving them out is one of the most expensive errors, so review how supplemental pay factors into the rate.

When an employee earns at more than one rate, the math changes again.

How do you calculate overtime with multiple pay rates or bonuses?

When an employee works two roles at different rates, or earns a nondiscretionary bonus, you calculate overtime on a blended regular rate. Add all straight-time earnings, divide by total hours worked to get the blended rate, then pay the overtime premium on the hours over 40.

Here is a worked example for an employee with two pay rates:

• 35 hours at $15 equals $525
• 10 hours at $20 equals $200
• Total: 45 hours and $725 in straight-time pay
• Blended regular rate: $725 divided by 45 equals $16.11
• Overtime premium: 5 hours times $16.11 times 0.5 equals $40.28
• Total weekly pay: $725 plus $40.28 equals $765.28

Employers who track total compensation carefully avoid the bulk of wage claims.

Salaried non-exempt employees with changing hours use a separate method.

What is the fluctuating workweek method?

The fluctuating workweek method lets you pay a salaried non-exempt employee a fixed weekly salary for all hours worked, then add a half-time premium for hours over 40. It is allowed only when hours genuinely vary, the salary covers straight time for every hour, and there is a clear mutual understanding.

An example makes it concrete:

• Weekly salary: $900
• Hours worked: 55
• Regular rate: $900 divided by 55 equals $16.36
• Overtime premium: 15 hours times $16.36 times 0.5 equals $122.70
• Total pay: $900 plus $122.70 equals $1,022.70

A single missed condition can void this method, so running payroll accurately with software that recalculates the rate every week removes most of the risk.

Once the pay is calculated, one more 2026 change affects what actually lands in the employee's pocket: tax.

Is overtime pay taxed, and what did the 'No Tax on Overtime' law change?

Overtime pay is still taxable, but the 2025 One Big Beautiful Bill Act created a temporary federal income tax deduction on the premium portion of qualifying overtime for tax years 2025 through 2028. The deduction covers the extra half of time-and-a-half pay, not the whole overtime paycheck, and Social Security and Medicare taxes still apply to all of it.

The deduction is capped at $12,500 a year for single filers and $25,000 for joint filers, and it phases out once modified adjusted gross income passes $150,000 (single) or $300,000 (joint). It applies to federal income tax only, so it helps to understand the difference between payroll tax and income tax before you explain it to staff.

The new deduction sits on top of the usual payroll taxes every employer must withhold from wages.

For the employee, the change can raise take-home pay without any change to how you calculate the gross overtime amount, as of IRS guidance issued in January 2026.

Employees will see the benefit once the year's post-tax deductions and filing are settled.

For employers, your calculation does not change, but how overtime appears on tax forms does, so your payroll deductions and reporting need to keep up.

Even with clear rules, a handful of mistakes account for most overtime disputes.

What are the most common overtime calculation mistakes?

The costliest overtime mistakes are misclassifying employees as exempt, leaving bonuses out of the regular rate, tracking time inaccurately, and ignoring stricter state rules. Each one is avoidable with a consistent process and reliable records.

Watch for these five errors in particular:

• Employee misclassification: labeling a non-exempt worker as exempt to avoid overtime is the single most common wage claim.
• Excluding bonuses and commissions: the regular rate must include nondiscretionary incentive pay, or every overtime hour is underpaid.
• Inaccurate time tracking: manual timesheets miss hours and invite disputes, while automated tracking protects both sides.
• Ignoring stricter state rules: applying only the federal 40-hour rule in a daily-overtime state like California underpays employees.
• Averaging hours across weeks: overtime is per workweek, so averaging a light week against a heavy one is never allowed.

Any one of these can lead to back wages plus an equal amount in liquidated damages, on top of other payroll obligations like wage garnishment, and wage-and-hour claims are among the most expensive employment lawsuits. As one employment attorney put it:

Wage and hour disputes seem to lead the pack relative to employment class-action litigation. These types of lawsuits are cash cows for plaintiffs' attorneys because attorney fees are relatively easier to obtain than in other forms of commercial litigation and because liquidated damages may be included.

Charles Krugel, employment attorney, quoted by SHRM.

The economics are simple, as another labor attorney summed up:

A dollar spent on risk management and compliance is better than a dollar spent on settling a class-action lawsuit.

Gerald Maatman Jr., Seyfarth Shaw, quoted by SHRM.

The most reliable way to avoid these mistakes is to hand overtime and compliance to a team that does it every day.
