Overtime – formal definition

Almost everybody in the working-age population knows and understands what is overtime. In some professions, working overtime is very common (or even mandatory!). Examples of personnel often working overtime might be construction workers, IT professionals, plant managers, and investment-related workers.

Besides all of that, let's take a look at the formal overtime definition. Overtime is the amount of time that an employee works beyond regular working hours. Or, in other words – overtime refers to any hours that someone worked exceeding their typically scheduled work-time. Moreover, the term overtime is often used to name the payment received for extra working hours.

Overtime rules

The number of normal working hours for a particular job position is established to balance the employee's health, productivity over the workday/shift, and general economic factors. It's known that the human organism is naturally limited and cannot sustain the same level of productivity in the 8th or 10th hour of work as at the beginning of the shift.

Depending on the job type, the number of regular working hours might be determined by the best practices of a profession (based on the trade experience), agreements between sides, or legislation. Whatever it is, it has to fulfill the national or local labor law regulations. Most commonly, a workday is 8 hours, and a workweek equals 40 hours.

Many countries design their labor laws to prevent employees from being forced to work long overtime hours. Furthermore, they usually provide regulations of overtime compensation.

What is time and a half?

Overtime payments are commonly called the overtime premium or the overtime rate of pay. The most usual rate for overtime hours is time and a half, and that is 50% more than employee's standard wage. It means that for every hour of overtime, you receive an equivalent of 1.5 the regular hourly rate. So, if you want to repair your personal budget, do some overtime work!

Keep in mind that this value may vary across countries and companies, so make sure to enter the correct multiplier into the overtime calculator.

According to the FLSA rules, nights, weekends, or holidays do not require to be paid as overtime (unless the worker would cross the regular hours' threshold). Many employers state additions to regular wages for hours done on evenings, weekends, or holidays on their own.

Formulas for overtime pay

You can use some simple formulas to calculate the overtime salary. First of all, you have to calculate your hourly overtime wages:

HOP = HRP * m,

where HOP stands for hourly overtime pay, HRP for the hourly regular pay, and m for the multiplier (most typically 1.5).

Once you know this value, you can calculate your total overtime pay:

OP = HOP * n,

where OP is the overtime pay, and n is the number of overtime hours in a month.

Finally, if you want to find your total salary at the end of the month, you have to add it to your regular salary:

TP = OP + RP,

where TP stands for total pay and RP stands for regular pay. The second one equals the regular hourly pay multiplied by the number of working hours per month.

How to calculate overtime pay?

  1. Begin with specifying your regular pay. Let's assume you earn $10 an hour. Input this value into the overtime calculator. If you don't know what it is, you can use this salary to hourly calculator.
  2. The next step is determining the number of hours you usually work per month. Assuming four weeks, 40 hours each, you can enter 160 hours per month.
  3. Change the multiplier so that it corresponds to your company's overtime policy. For example, your company may pay the usual time and a half rate – the multiplier is equal to 1.5.
  4. Determine the number of hours you worked overtime this month. Let's say you worked 30 hours overtime.
  5. Our overtime calculator will automatically find all other values – your regular pay, overtime pay, and their sum as the total salary you will receive this month.

Once you have calculated your total pay, you can decide what to do with it – are you planning to spend it or maybe invest it?

Exemptions from overtime pay

Overtime laws obligate employers to pay their workers a greater rate than the standard wage for regular hours. As mentioned above, the typical threshold in most countries (including the U.S.) is 40 work hours a week. Whatever the limit is (some laws contain other thresholds), the employer should compensate each hour exceeding the normal threshold.

However, in the U.S., according to the Fair Labor Standards Act (FLSA), specific jobs are excluded from overtime compensation requirements. They are called exempt, and employers are not obligated to pay overtime in these cases. Accordingly, employees who are generally eligible for overtime compensation are referred to as non-exempt employees.

In addition to excluding particular workers from overtime rules, some overtime laws list specific industries where employers are exempt from overtime requirements.

Exempt employees – formal requirements

In the U.S., exempt jobs are determined by the Fair Labor Standards Act. There are many requirements to be fulfilled to consider an employee as an exempt one. Let's take a look at executive and administrative workers and how the exemption works for them.

To qualify for the executive employee exemption, all of the following tests must be met:

  • The employee must be compensated on a salary basis (as defined in the regulations) at a rate not less than $455 per week;
  • The employee's primary duty must be managing the enterprise or managing a customarily recognized department or subdivision of the enterprise;
  • The employee must customarily and regularly direct the work of at least two or more other full-time employees or their equivalent; and
  • The employee must have the authority to hire or fire other employees. Or at least the employee's suggestions and recommendations as to the hiring, firing, advancement, promotion, or any other change of status of other employees must be given particular weight.

To qualify for the administrative employee exemption, all of the following tests must be met:

  • The employee must be compensated on a salary or fee basis (as defined in the regulations) at a rate not less than $455 per week;
  • The employee's primary duty must be the performance of office or non-manual work directly related to the management or general business operations of the employer or the employer's customers; and
  • The employee's primary duty includes the exercise of discretion and independent judgment with respect to matters of significance.

Keep in mind that while someone gets a salary, it does not automatically determine them as exempt. A salaried employee might still be a non-exempt worker. Every individual has to perform qualifying duties to be classified as an exempt one.

Exempt jobs – examples

Below you can find a few other examples of job types that are excluded from overtime payments:

  • Babysitters on a casual basis
  • Companions for the elderly
  • Fishermen
  • Fruit & vegetable transportation employees
  • Local delivery drivers
  • Newspaper delivery
  • Police officers in departments with less than five officers
  • Railroad employees
  • Seamen on vessels
  • Taxicab drivers
