Fluctuating Workweek Method: How It Works for Overtime
Quick Answer
The fluctuating workweek method is a federal way to pay overtime to salaried, non-exempt employees whose hours change from week to week. The employee gets a fixed weekly salary for all hours worked, plus overtime at one-half the regular rate for hours over 40. The regular rate changes each week: it's the salary plus any other non-excludable pay, divided by hours worked. It only works if hours truly fluctuate, there's a clear mutual understanding, and the salary covers at least minimum wage for every hour. State law may restrict it.
Not every salaried employee is exempt from overtime. Office managers, coordinators, assistant managers and many other roles are often paid a salary but still qualify for overtime under federal law. For those employees, figuring out overtime can be confusing, especially when their hours change a lot from week to week.
The fluctuating workweek method is one way federal law allows employers to handle that situation. It can lower overtime costs compared with standard time and a half, but it has strict requirements, and getting them wrong can turn a cost-saving method into back-pay liability. This guide explains how it works in plain language, with worked examples, the federal requirements and the state law issues to check.
Note: This is general information, not legal advice. The fluctuating workweek method comes from Department of Labor regulations, and state law may restrict it. Check with an employment attorney and your state labor department before using it.
Salaried Doesn't Mean Exempt
Under the Fair Labor Standards Act (FLSA), employees must receive overtime pay for hours worked over 40 in a workweek at a rate not less than time and one-half their regular rate of pay, unless they're specifically exempt. Being paid a salary doesn't by itself make someone exempt. Exemptions depend on the employee's duties and pay meeting specific tests.
So a salaried, non-exempt employee is still owed overtime. The question is how to calculate it. See what a non-exempt worker is and salary vs. hourly pros and cons for background.
What Is the Fluctuating Workweek Method?
Under the fluctuating workweek method, a non-exempt employee receives a fixed salary that covers all hours worked in the week, whether that's 30 hours or 50. Because the salary already pays for every hour at straight time, overtime is paid at one-half the regular rate, not one and one-half, for each hour over 40.
The catch is that the regular rate isn't fixed. It changes every week, because the same salary is divided by a different number of hours. The more hours worked, the lower the regular rate and the lower the overtime premium per hour.
| Standard salaried non-exempt | Fluctuating workweek | |
|---|---|---|
| What the salary covers | A set number of hours, such as 40 | All hours worked in the week |
| Regular rate | Salary divided by the hours it's meant to cover | Salary divided by actual hours worked that week |
| Overtime rate | 1.5 times the regular rate | 0.5 times the regular rate |
| Short weeks | Depends on the arrangement | Full salary is still paid |
| Cost of long weeks | Higher | Lower |
The Federal Requirements
Department of Labor regulations at 29 CFR 778.114 set out when the method can be used. All of these must be true:
- Hours fluctuate. The employee works hours that fluctuate from week to week.
- Fixed salary. The employee receives a fixed salary that does not vary with the number of hours worked in the workweek, whether few or many.
- Minimum wage is covered. The salary is large enough to provide compensation at not less than the applicable minimum wage for every hour worked in the workweeks with the most hours.
- Clear mutual understanding. The employer and employee have a clear and mutual understanding that the fixed salary is compensation for the total hours worked each workweek, whatever their number, rather than for a fixed number of hours.
- Half-time overtime is paid. The employee receives extra compensation for all overtime hours at not less than one-half the regular rate of pay for that workweek.
The fixed salary generally needs to be paid in full even in weeks when the employee works fewer hours. If you regularly cut the salary in short weeks, the arrangement may not qualify.
How to Calculate Pay Under the Fluctuating Workweek Method
- Add up total straight-time pay: the fixed salary plus any additional pay that must be included in the regular rate, such as non-discretionary bonuses or premium pay.
- Divide by total hours worked that week to get the regular rate.
- Multiply the regular rate by 0.5 to get the overtime premium per hour.
- Multiply by overtime hours (hours over 40).
- Add the overtime to the straight-time pay for total pay.
Example: The Department of Labor's Numbers
The regulation includes an example of an employee paid a fixed salary of $600 a week with no other pay. Here's how the numbers work across four different weeks:
| Hours worked | Regular rate (salary / hours) | Overtime hours | Overtime pay (0.5 x rate x OT hours) | Total pay |
|---|---|---|---|---|
| 37.5 | $16.00 | 0 | $0 | $600.00 |
| 44 | $13.64 | 4 | $27.28 | $627.28 |
| 48 | $12.50 | 8 | $50.00 | $650.00 |
| 50 | $12.00 | 10 | $60.00 | $660.00 |
Notice that the regular rate drops as hours rise, so each extra overtime hour costs a little less. In the 37.5-hour week, the employee still gets the full $600.
Comparison: Fluctuating Workweek vs. Time and a Half on a 40-Hour Salary
Compare the same $600 salary if it's treated as covering 40 hours, so the regular rate is $15.00 and overtime is $22.50 an hour:
| Hours worked | Fluctuating workweek total | Standard method total | Difference |
|---|---|---|---|
| 44 | $627.28 | $690.00 | $62.72 |
| 48 | $650.00 | $780.00 | $130.00 |
| 50 | $660.00 | $825.00 | $165.00 |
That difference is why some employers use the fluctuating workweek method, and why it's closely scrutinized. Make sure every requirement is met before relying on it.
Bonuses and Premium Pay
Since a 2020 update to the regulation, the Department of Labor says that paying bonuses, premium payments, commissions, hazard pay and other additional pay is compatible with the fluctuating workweek method. But that additional pay must be included in the regular rate unless it's excludable under the FLSA.
The regulation gives examples. Using the same $600 salary and a 48-hour week:
| Scenario | Straight-time pay | Regular rate | Overtime (8 hours x half rate) | Total |
|---|---|---|---|---|
| Salary only | $600 | $12.50 | $50.00 | $650.00 |
| Plus $20 night-shift premium | $620 | $12.92 | $51.68 | $671.68 |
| Plus $100 productivity bonus | $700 | $14.58 | $58.32 | $758.32 |
Leaving bonuses out of the regular rate is one of the most common overtime mistakes. See bonuses in employment compensation.
The Minimum Wage Check
Because the regular rate drops as hours rise, very long weeks can push it below minimum wage. The regulation requires the salary to be large enough to cover the applicable minimum wage for every hour worked, even in the longest weeks. Run the math for your busiest realistic week:
| Weekly salary | Hours in longest week | Regular rate | Above $7.25 federal minimum? |
|---|---|---|---|
| $600 | 60 | $10.00 | Yes |
| $400 | 60 | $6.67 | No |
| $450 | 55 | $8.18 | Yes |
If your state or city has a higher minimum wage, check against that rate instead. The Department of Labor also says the regular rate can't be less than the minimum wage.
State Law Can Restrict or Prohibit the Method
The fluctuating workweek method is a federal rule. State wage laws can be stricter than federal law, and a state may restrict the method or have overtime rules, such as daily overtime, that make it impractical. Before using it, check your state's wage and hour rules or talk to an employment attorney. If you have employees in more than one state, check each one. See the overtime laws by state guide.
When Does the Method Make Sense?
| Good fit | Poor fit |
|---|---|
| Hours truly vary a lot week to week | Hours are steady at or near 40 |
| Employee prefers a predictable paycheck | Employee often works short weeks and you'd want to reduce pay |
| Salary comfortably covers minimum wage in long weeks | Salary is close to minimum wage |
| Your state allows it | Your state restricts it or has daily overtime |
| You can document a clear agreement | The arrangement is informal or unclear |
How to Set Up the Fluctuating Workweek Method
- Confirm the employee is non-exempt and that the role's hours truly fluctuate.
- Check state law.
- Set a salary that covers minimum wage in the longest realistic week.
- Explain the method in writing and get the employee's acknowledgment, so there's a clear mutual understanding.
- Track every hour worked. You can't calculate the regular rate without accurate hours.
- Pay the full salary every week, including short weeks.
- Include bonuses and premiums in the regular rate.
- Review the arrangement regularly.
Sample Written Explanation
Fluctuating Workweek Pay Plan
Your position is non-exempt and eligible for overtime. You will be paid a fixed weekly salary of $[amount], which is compensation for all hours you work each workweek, whether fewer or more than 40.
For any hours over 40 in a workweek, you will receive additional overtime pay equal to one-half of your regular rate for that week. Your regular rate is your weekly salary, plus any bonuses or premium pay that must be included, divided by the total hours you worked that week. Because your hours vary, your regular rate and overtime pay will vary from week to week.
Our workweek runs from [day and time] to [day and time]. You must record all hours worked.
Employee acknowledgment: I understand and agree to this pay plan.
Signature: [ ] Date: [ ]
Have an employment attorney review the language before using it.
Common Fluctuating Workweek Mistakes
- Using it for employees whose hours don't really fluctuate.
- Docking the salary in short weeks.
- No written explanation or acknowledgment.
- Not tracking hours, so the regular rate can't be calculated.
- Leaving bonuses or premiums out of the regular rate.
- Letting the regular rate fall below minimum wage in long weeks.
- Ignoring state law.
- Assuming salaried means exempt.
Fluctuating Workweek Checklist
| Step | Done? |
|---|---|
| Employee confirmed non-exempt | |
| Hours truly fluctuate week to week | |
| State law checked | |
| Salary covers minimum wage in longest weeks | |
| Written explanation signed by employee | |
| All hours tracked | |
| Full salary paid every week | |
| Bonuses and premiums included in regular rate |
A Month Under the Fluctuating Workweek Method
Here's how a $750 weekly salary works out over a month when an assistant manager's hours change each week:
| Week | Hours | Regular rate | Overtime hours | Overtime pay | Total pay |
|---|---|---|---|---|---|
| 1 | 38 | $19.74 | 0 | $0.00 | $750.00 |
| 2 | 46 | $16.30 | 6 | $48.90 | $798.90 |
| 3 | 52 | $14.42 | 12 | $86.52 | $836.52 |
| 4 | 42 | $17.86 | 2 | $17.86 | $767.86 |
| Total | 178 | 20 | $153.28 | $3,153.28 |
The employee receives the full $750 in the short week and extra pay in every overtime week. Each week is calculated on its own, because the FLSA applies on a workweek basis.
Questions Employees Often Ask
"Why does my overtime rate change every week?" Because your salary covers all your hours, your hourly rate is your salary divided by the hours you worked that week. When you work more hours, the rate is lower, so the half-time overtime premium is lower too.
"Do I still get my full salary if I work fewer hours?" Yes. Under this method, the fixed salary is paid regardless of how many hours you work in the week.
"Why don't I get time and a half?" Your salary already pays straight time for every hour, including overtime hours. The extra half-time is paid on top of that.
Alternatives to the Fluctuating Workweek Method
| Option | How it works | Best for |
|---|---|---|
| Hourly pay | Pay an hourly rate, with time and a half over 40 | Most non-exempt roles |
| Salary for a fixed number of hours | Salary covers a set schedule, such as 40 hours; overtime at 1.5 times the regular rate | Steady schedules |
| Fluctuating workweek | Salary covers all hours; half-time overtime | Truly variable hours, where state law allows |
| Reclassify as exempt | Only if the role truly meets an exemption test | Roles that meet duties and pay tests |
If you're unsure whether a role is exempt, see the 4-hour rule for exempt employees and talk to an employment attorney.
Records to Keep
- The signed written explanation of the pay plan.
- Hours worked each day and each workweek.
- The fixed weekly salary paid each week.
- Any bonuses, premiums or other additional pay.
- The regular rate and overtime calculation for each workweek.
Good records protect both you and the employee if questions come up later. See how to track employee hours.
Talking With Employees Before You Switch
If you're moving an employee to this method, explain it before the change takes effect, show sample weeks with their real salary and give them time to ask questions. A clear conversation, followed by a signed written explanation, is the best way to show the clear mutual understanding the regulation requires.
Track Hours and Overtime With Updoot
The fluctuating workweek method depends on knowing exactly how many hours each salaried non-exempt employee worked. Updoot's employee time clock records every punch to the minute, and the payroll report shows weekly hours and overtime hours for every employee, so you or your payroll provider have accurate numbers for the regular rate calculation each week.
