Calculating Time Worked & Overtime

Understand the difference between worked time and non-worked time for overtime calculations

Updated over 2 years ago

It's important to understand the difference between worked time and non-worked time for overtime calculations. Continue reading to learn:

  • How the regular rate of pay is calculated and used to determine the amount of overtime pay an employee must be paid under the FLSA

  • How multiple rates of pay can retroactively affect the regular rate of pay and the overtime calculation


Time Worked and Overtime

A few important notes regarding Overtime:

  • Overtime is a premium to hourly pay and granted for time worked within a workweek that exceeds 40 hours

  • The regular rate of pay determines how overtime is calculated

  • Calculating the overtime premium is based on the regular rate of pay, which can change based on things like quarterly bonuses or if an employee is paid different rates throughout the workweek in which overtime occurs


Time Worked

When calculating the regular rate of pay, the formula is Pay for all hours worked (less exceptions), divided by All Hours Worked.

In order to calculate All Hours Worked we need to understand when an employee must be compensated for all of the hours they spend on their job. However, there are certain activities that are not compensable.

  • For example, time commuting to a job site may or may not be a compensable event.

Below is a table of relevant definitions:

Workday

A workday may be no longer than the employee’s scheduled shift, hours, tour of duty, or time on a production line. Workdays may vary from day to day, depending on when the employee starts or stops their principal activities.

Preliminary or Postliminary Activities

Any activity that must be accomplished during a portion of the workday are compensable if defined as such by union contract, custom, practice, or regulatory guidance. (e.g., changing clothes, cleaning tools)

Principal Activities

All activities deemed an integral part of the business; they are so closely related as to be indispensable to its performance (e.g., maintenance of machinery - oiling, greasing, cleaning, installing new parts)

Activities not considered integral - punching in and out or waiting in line to do so; passing through security devices; and traveling to the job site

Donning & Doffing (changing clothes)

This can be a tricky area of compensability. If the changing of clothing at the beginning or the end of the shift is an integral and indispensable to the company’s principal activities, then it is likely compensable time. Usually this time is required by regulatory guidance, company policy, safety reasons, or under a union contract. If, on the other hand, it is just for the convenience of the employee, it would not be considered compensable time. (e.g., putting on such items as hard hats, protective eye gear, hair nets)

Call-back & Show-up Pay

Some employers, for various reasons, pay call-back (aka call-out) pay whenever an employee gets called back to work after the end of their shift. Additionally, some companies pay show-up (aka reporting) pay if one of their employees arrives at work for their designated shift but there is no work for them to perform. In both of these cases, the hours paid but not actually worked are not counted towards the 40 hours worked for overtime purposes.

Waiting Time

According to the FLSA, an employee does not always have to be productively working in order for those hours to be considered productive and therefore, not only compensable, but used to calculate hours worked for both the regular rate of pay and overtime.

  • Engaged to be Waiting - If the employee’s activities are restricted, the employee cannot come and go as they please, the time is likely considered to be Engaged to be Waiting and therefore compensable. (e.g., employee waiting at the end of the car wash to dry the vehicles as they come out)

  • Waiting to be Engaged - If the employee is completely relieved of any duties and are free to leave the premises (regardless whether they do or not) are considered to be Waiting to be Engaged. This time is not compensable and not considered time worked for either the regular rate of pay or overtime (e.g., production line is down, repairs are going to take 4 hours, all employees are released until 1 pm)

Travel Time

The reason for the travel will determine if it is compensable and added to hours worked.

  • Commuting - Travel to and from work is not compensable time. These hours are not considered for either the regular rate of pay or overtime

  • Home to Work on a Special One-Day Assignment - The time traveling to a worksite on an occasional basis is compensable and must be included in the formulas. However, the amount of time the employee usually spends commuting to and from work can be deducted. (e.g., the normal commute is 30 minutes. Travel to and from a special assignment is 90 minutes. The compensable travel time is 60 minutes)

  • Travel All in a Day's Work - If an employee travels to different locations or worksites within a workday, the travel time between sites is compensable. However, the travel time from home to worksite #1 is not compensable. Nor is the travel from the last worksite back home.

  • Travel Away From Home - Travel away from the employee’s general location of work or home is compensable time. However, only the hours traveled during the regularly scheduled hours are compensable. Normal lunch breaks can be deducted. Even if the travel is not on a usually scheduled day


Example - Fred usually works from 8am - 5 pm with a 1 hour lunch break, Monday - Friday. Fred is asked to travel to a conference in a city several hundred miles away. He travels on the Sunday prior to the conference which runs Monday to Thursday. He then stays in the conference city over the weekend and returns home on Sunday. He travels on each Sunday from 11 am to 8 pm. Fred would need to get paid from 11 am - 5 pm less 1 hour for lunch break each Sunday. So Fred would get paid for 5 hours each Sunday plus the 32 hours he attended the conference. So Fred would be compensated for 42 hours (2 hours of overtime)

Overtime Pay Calculations

Under the FLSA, overtime pay must be paid at 150% ( 1 ½ times) of the regular rate of pay for all hours actually worked over 40 during each workweek. This is often referred to as “time and a half”.

First, let’s look at some terminology that is important to understand the formula we are considering.

  • Regular rate of pay: total compensation for actual time worked / total hours worked. This is the “time” part of “time and a half”.

  • Overtime (OT) hours: all hours actually worked over 40 in each workweek

  • OT premium rate: 50%, or 0.5, of the regular rate of pay. This is the “half” part of “time and a half”.

  • OT premium pay: OT hours x OT premium rate. This on top of the regular pay rate for hours worked over 40 in a workweek.

In order to calculate the regular rate of pay, we have to consider a few scenarios:

Shift Differentials

When an employee is paid a shift premium or differential for special hours (e.g., evening shift, night shift, weekend days), the shift differential needs to be added to the regular rate of pay before overtime is calculated

Example: Theodore is paid $10.00 per hour. When he works the evening shift, he receives an additional $0.75 per hour as a shift differential. His regular rate of pay would be $10.75 per hour rather than $10.00 for overtime purposes.

Multiple Rates of Pay

When an employee works different jobs and earns a different rate for each position, to calculate the regular rate of pay, the weighted average must be calculated.

Example - Wyatt works as a dishwasher and a prep cook at one of the local restaurants. As a dishwasher, he makes $9.00/hr and $12.50/hr as a prep cook. In one workweek, he worked 25 hours as a dishwasher and 20 hours as a prep cook.

Step

Calculation

Result

Regular Pay

(25 hours x $9.00) + (20 hours x $12.50)

$475.00

Total Hours

25 hours + 20 hours

45 total hours

OT Hours

45 hours - 40 hours

5 hours of OT

Calculated Regular Rate of Pay

$475.00 / 45 hours

$10.56

Any hours worked over 40 would therefore have to be paid out at $10.56 x 1.5 = $15.84 for each of the hours worked past 40 hours.

Alternatively, the employer could have chosen to use the highest rate of pay that was paid during the corresponding workweek. In this case, $12.50, for an an OT rate of $12.50 x 1.5 = $18.75

Nondiscretionary Bonuses

Any contractual or agreed-upon bonus related to efficiency, production, attendance, quality, or any other measure of performance is considered a nondiscretionary bonus and must be included when calculating the regular rate of pay for overtime purposes. Many times, these bonuses cannot be tied to just one workweek. If this is the case, they must be evenly divided into each workweek the bonus covers and (often after regular wages have already been paid) must be added into the regular wages for the calculation of overtime.

Example: Fernando earns a quarterly production bonus of $500 for the first quarter of 2021. During one week of the quarter, she worked 44 hours and was paid $15.00/hour. A quarterly bonus would be evenly divided by 13 weeks.

Step

Calculation

Result

Regular pay

44 hours x $15.00

$660.00

Bonus (per week)

$500.00 / 13 weeks

$38.46

Total weekly regular pay

$660.00 + $38.46

$698.46

Calculated Regular Rate of Pay

$698.46 / 44 hours

$15.87

Note: Consider that the OT was performed earlier in the quarter before the bonus was paid at the end of the quarter. It would have been paid at “time and a half” which would have been $22.50/hour ($15 + the OT Premium of $7.50/hour) at the time. However, we can see that after the bonus was paid and prorated across each week in the quarter, the OT Premium would have changed from $7.50 to $15.87 / 2 = $7.94 for “time and a half” of $22.94. The employee would have to be compensated for this difference of $0.44 per hour of OT. In this case $0.44 x 4 hours = $1.76.
