The fluctuating workweek method

A way to pay overtime to salaried non-exempt employees whose hours change from week to week, and the conditions you must meet to use it.

In shortUnder the fluctuating workweek (FWW) method, a non-exempt employee receives a fixed salary that covers all hours worked in the week, whatever their number. For overtime hours, the employer pays an extra half of the regular rate, which is the salary divided by the hours worked that week. It is allowed under federal rules only if specific conditions are met, and some states, such as California, do not allow it.

When the method is used

The FWW method is used for salaried non-exempt employees whose hours vary week to week, sometimes below 40 and sometimes above. Examples might include some office coordinators, technicians or assistant managers who do not meet an exemption. The employer pays a predictable salary, and the employee receives overtime when hours exceed 40, but at a lower premium than under the standard method.

The conditions

Under the Department of Labor’s rules (29 CFR 778.114), the method generally requires that:

  1. The employee is non-exempt and works hours that fluctuate from week to week.
  2. The employee receives a fixed salary that does not vary with the number of hours worked, including in weeks with fewer hours.
  3. The salary is large enough that the regular rate never falls below the minimum wage, even in the longest week.
  4. There is a clear mutual understanding that the fixed salary covers all hours worked in the week, not a set number of hours.
  5. The employee receives an overtime premium of at least half the regular rate for every hour over 40.

Since a 2020 rule, the DOL has stated that paying bonuses, premiums or other additional pay on top of the salary does not by itself prevent use of the method, as long as such payments are included in the regular rate. Deductions from the salary for short weeks generally break the arrangement, except in limited cases.

How the calculation works

Each week, you calculate a new regular rate because hours change:

Regular rate = weekly salary (plus any other includable pay) / total hours worked that weekOvertime pay = 0.5 x regular rate x hours over 40

The salary already pays straight time for every hour, so only the half-time premium is added.

A worked example

A fictional employee earns a fixed salary of $1,000 per week under a valid FWW arrangement.

FWW calculation across three weeks
Week Hours worked Regular rate Overtime premium Total pay
Week 1 36 $27.78 $0.00 $1,000.00
Week 2 44 $22.73 4 x $11.36 = $45.45 $1,045.45
Week 3 50 $20.00 10 x $10.00 = $100.00 $1,100.00

Under the standard method, if $1,000 were intended to pay for 40 hours, the regular rate would be $25 and 10 overtime hours would cost 10 x $37.50 = $375 on top of the salary. That difference is why the method is attractive to employers, and also why it is closely examined when challenged. Rounding is to the cent for readability.

State rules

Several states do not allow the fluctuating workweek method or limit it. California, for example, generally does not permit it, and other states have restricted it through regulation or court decisions. Before using the method, check the law in each state where your employees work. Where it is not allowed, use the standard overtime calculation described in our guide to the regular rate of pay.

Risks and common mistakes

If the method is found invalid, the employer may owe overtime under the standard calculation for past weeks, which can be a large amount.

Setting up an FWW arrangement

  1. Confirm the employee is non-exempt and that their hours really vary from week to week.
  2. Check that the method is allowed in the state where the employee works.
  3. Set a salary high enough that the regular rate stays above the applicable minimum wage in the longest realistic week.
  4. Put the arrangement in writing: the salary covers all hours worked, overtime is paid at half the regular rate, and the salary will not be reduced in short weeks.
  5. Configure payroll to recalculate the regular rate every week.
  6. Review the arrangement each year, or sooner if the role or hours change.

Is it right for your business?

The method can suit businesses where hours genuinely vary and both sides value a stable salary. But it is technical, it is restricted in some states, and employees sometimes see it as unfair because the overtime rate falls as hours rise. Many small businesses find it simpler to pay hourly with standard overtime, or to schedule so that overtime is rare. Discuss the options with a payroll professional or employment attorney before deciding.

Tracking hours under FWW

Salaried non-exempt employees still need full time records: every workday’s hours and every week’s total. Without them, you cannot calculate the weekly regular rate. With EZTime, salaried non-exempt employees clock in and out like hourly staff, using the app, a kiosk or NFC, and managers see weekly totals and overtime as they build up. Approved hours export to payroll, where the FWW calculation is applied. See also exempt vs. non-exempt employees.

Frequently asked questions

What is the fluctuating workweek method?

A way of paying overtime to salaried non-exempt employees, where the salary covers all hours and overtime is paid at half the weekly regular rate.

Is the fluctuating workweek method legal?

It is allowed under federal rules when all conditions are met. Some states, such as California, do not allow it.

Can I deduct pay in a short week under FWW?

Generally no. The salary must stay fixed regardless of hours, with only limited exceptions.

Can I pay bonuses under FWW?

Under the DOL’s 2020 rule, yes, as long as they are included in the regular rate for overtime.

Is FWW the same as a salaried exempt arrangement?

No. FWW employees are non-exempt and are owed overtime. Exempt employees are not owed overtime under federal law.

Do I need to track hours for FWW employees?

Yes. They are non-exempt, so you need daily and weekly hour records to calculate overtime.
