Managing payroll accurately is essential for compliance and transparency. In both the US and UK, overtime must be calculated and reported correctly to ensure employees are paid fairly and employers remain compliant with labor laws.
Our free overtime hours calculator makes it easy to track how much time an employee has worked beyond their regular hours in a week. This metric is vital for calculating additional pay, managing workloads, and preventing burnout.
How the calculation works
Overtime hours are calculated by subtracting an employee's standard weekly hours from their total hours worked. In the US, under the Fair Labor Standards Act (FLSA), non-exempt employees must be paid 1.5 times their regular hourly rate for any hours worked beyond 40 in a workweek. In the UK, there is no legal requirement to pay overtime, but it is common to do so at agreed rates if hours exceed normal working hours.
The formula used is:
Overtime hours = Total hours worked - Standard weekly hours
If the employee works more than the standard hours, the excess is considered overtime. This calculator will also display the total hours worked and the overtime hours, depending on your country’s rules.
