Overtime Pay Calculator
Calculate overtime pay at time and a half, double time, or a custom multiplier and see your total weekly pay.
How to Calculate Overtime Pay
Use this overtime pay calculator to estimate extra earnings from time and a half, double time, or a custom overtime multiplier. It helps employees check payslips and weekly totals, and it helps managers estimate labour cost for extended shifts or peak periods.
Enter your regular hourly rate, regular hours, and overtime hours. The calculator multiplies each overtime hour by the premium rate, adds that amount to your regular pay, and then shows total pay and your effective hourly rate for the full week.
Overtime Pay Formula
Overtime Pay = Regular Hourly Rate × Overtime Multiplier × Overtime Hours
Total Pay = Regular Pay + Overtime Pay
Effective Hourly Rate = Total Pay / Total Hours Worked
Where:
- Regular Hourly Rate = Your standard pay rate per hour
- Overtime Multiplier = The premium rate factor (1.5x for time-and-a-half, 2x for double time, or a custom value)
- Overtime Hours = Total hours worked beyond the standard work schedule
- Regular Pay = Regular Hourly Rate × Regular Hours Worked
Understanding FLSA Overtime Rules
The Fair Labor Standards Act (FLSA) in the United States establishes the federal standard for overtime pay. Under the FLSA, non-exempt employees must receive overtime pay at a rate of not less than 1.5 times their regular rate of pay for all hours worked over 40 in a workweek. It is important to note that the FLSA calculates overtime on a weekly basis, not daily. This means that even if you work 12 hours in a single day, you would not be entitled to federal overtime pay unless your total hours for that week exceed 40. However, some states, like California, have daily overtime rules that require overtime pay for hours worked beyond 8 in a single day and double time for hours beyond 12.
The FLSA exempts certain categories of employees from overtime requirements, including executive, administrative, professional, computer, and outside sales employees who meet specific criteria related to their job duties and salary level. These are known as "exempt" employees. The salary threshold for exemption is periodically updated by the Department of Labor. If you are classified as exempt, you are generally not entitled to overtime pay regardless of how many hours you work. Misclassification of employees as exempt when they should be non-exempt is a common source of labor disputes and wage claims.
Time and a Half vs. Double Time
Time and a half (1.5x) is the standard overtime multiplier required by federal law in the United States and is the most widely used overtime rate globally. It means you earn 50% more per hour than your regular rate. For example, if your regular rate is $20 per hour, your time-and-a-half rate would be $30 per hour. Double time (2x) means you earn twice your regular rate. Using the same example, double time would pay $40 per hour. Double time is typically reserved for specific situations such as working on holidays, working beyond a certain number of overtime hours in a day, or as specified in collective bargaining agreements. Some employers voluntarily offer double time as an incentive for employees to work undesirable shifts or during peak demand periods.
Example Calculations
Example 1: $25/hr with 10 Overtime Hours at 1.5x
An employee earns $25 per hour, works 40 regular hours and 10 overtime hours at time and a half.
- Regular Pay = $25 × 40 = $1,000.00
- Overtime Rate = $25 × 1.5 = $37.50/hour
- Overtime Pay = $37.50 × 10 = $375.00
- Total Pay = $1,000.00 + $375.00 = $1,375.00
- Effective Hourly Rate = $1,375.00 / 50 = $27.50/hour
Example 2: $30/hr with 5 Overtime Hours at 2x
An employee earns $30 per hour, works 40 regular hours and 5 overtime hours at double time.
- Regular Pay = $30 × 40 = $1,200.00
- Overtime Rate = $30 × 2 = $60.00/hour
- Overtime Pay = $60.00 × 5 = $300.00
- Total Pay = $1,200.00 + $300.00 = $1,500.00
- Effective Hourly Rate = $1,500.00 / 45 = $33.33/hour
Overtime Pay for Salaried Employees
Salaried employees who are classified as non-exempt are also entitled to overtime pay. To calculate overtime for a salaried employee, you first need to determine their regular hourly rate by dividing their weekly salary by the number of hours the salary is intended to cover (typically 40). Once the hourly rate is established, overtime is calculated the same way as for hourly employees. For example, if a non-exempt salaried employee earns $800 per week for 40 hours, their regular hourly rate is $20, and their overtime rate at 1.5x would be $30 per hour for any hours worked beyond 40 in that week.
State and International Variations
While the FLSA sets the federal minimum standard in the United States, individual states may have more generous overtime laws. California, for example, requires overtime pay for hours worked beyond 8 in a single day and double time for hours beyond 12 in a day, regardless of the weekly total. Some states also require overtime for working more than six consecutive days. Internationally, overtime regulations vary significantly. Many European countries have strict limits on working hours with mandated premium pay for overtime. In some Asian countries, overtime rates can be 1.25x, 1.5x, or higher depending on whether the overtime is on a regular workday, a rest day, or a holiday. Always check the specific labor laws in your jurisdiction to understand your overtime rights and obligations.
