About this calculator
The Overtime Calculator helps determine the amount to receive for overtime hours worked. It considers the monthly salary, monthly workload, number of overtime hours, and the additional percentage (usually 50%). The result shows the gross overtime pay, without tax or contribution deductions.
The calculation is straightforward: first, calculate the normal hourly rate by dividing the salary by the monthly hours. Then, multiply this rate by the number of overtime hours and apply the additional percentage (1 + percentage/100). For example, with a salary of R$ 2,000, 220 monthly hours, 10 overtime hours at 50%, the calculation is: hourly rate = 2000/220 ≈ R$ 9.09; overtime pay = 9.09 × 10 × 1.5 ≈ R$ 136.36.
Use this calculator to check your pay slip, plan personal finances, or negotiate compensation with your employer. It is useful for workers who frequently do overtime, such as during tight deadlines or shifts. Remember that the calculated amount is gross; the net amount received may be lower due to legal deductions.
Important considerations: ensure the monthly workload is correct (usually 220 hours for a 44-hour workweek). The minimum additional is 50% for weekdays and can reach 100% on Sundays and holidays. Habitual overtime may generate additional rights, such as impacts on vacation and 13th salary. Check your category's collective agreement to confirm applicable percentages.
