The "Chinese Overtime" method, officially known as the Fluctuating Workweek (FWW) method, is a specific way of calculating overtime pay for salaried employees whose hours vary from week to week. Use the calculator below to determine your effective hourly rate and total pay under this system.
What is Chinese Overtime?
Despite its colloquial name, "Chinese Overtime" has nothing to do with China. It is a legal method of payment under the Fair Labor Standards Act (FLSA) in the United States. It is technically called the Fluctuating Workweek method.
This method is designed for employees who receive a fixed salary but whose hours change—sometimes they work 35 hours, sometimes 50. The core logic is that the salary is intended to cover all hours worked, regardless of how many. Therefore, the "base" pay for overtime hours is already included in the salary, and only the "half-time" premium needs to be added.
How the Calculation Works
Calculating pay under the FWW method follows a specific four-step process:
- Step 1: Determine the Regular Rate. Divide the fixed weekly salary by the total number of hours actually worked that week.
- Step 2: Calculate the Overtime Premium. Since the salary already covers the hours at a "straight-time" rate, you only owe an additional 0.5x (half) of the regular rate for every hour over 40.
- Step 3: Calculate Overtime Pay. Multiply the Overtime Premium by the number of hours worked beyond 40.
- Step 4: Total Pay. Add the Overtime Pay to the Fixed Weekly Salary.
The Paradox of the Fluctuating Workweek
The most controversial aspect of this calculator is that the more you work, the less you earn per hour. Because the fixed salary is divided by total hours, your "regular rate" decreases as your hours increase. This is why many employee advocates dislike the method, while employers often find it a useful way to control labor costs during busy seasons.
Legal Requirements for Using FWW
Employers cannot simply decide to use this method on a whim. According to the Department of Labor (DOL), several criteria must be met:
- The employee's hours must actually fluctuate from week to week.
- The employee must receive a fixed salary that does not change based on the quality or quantity of work.
- The salary must be high enough that the regular rate never drops below the minimum wage.
- There must be a "clear mutual understanding" between the employer and employee that this method is being used.
Pros and Cons
For Employers
The primary benefit is cost predictability. It significantly reduces the cost of overtime compared to the traditional 1.5x hourly rate calculation. It also simplifies payroll for workers who don't have a standard 9-to-5 schedule.
For Employees
The benefit for employees is the "salary floor." If you work only 30 hours in a slow week, you still get your full fixed salary. However, the downside is that during "crunch time," your extra effort results in a lower hourly effective wage than a standard hourly worker would receive.
