What are overtime hours
Legal definition
Overtime hours refer to periods worked beyond the normal workday of 8 hours daily or 44 hours weekly, as established by CLT (Consolidação das Leis do Trabalho - Brazilian Labor Law Code).
All work performed beyond these limits must be compensated with a minimum additional of 50% over the normal hourly rate.
Types of additional pay
Brazilian legislation provides two main percentages for overtime:
- 50% additional: applied to regular overtime hours (weekdays)
- 100% additional: applied on Sundays and holidays (when there’s no compensatory time off)
Some collective agreements may establish higher percentages, always favoring the worker.
How to calculate overtime hours 2026
Calculating hourly rate
To calculate overtime, you first need to determine the normal hourly rate:
Formula: Monthly salary ÷ 220 hours = Normal hourly rate
Example: R$ 3,000 salary ÷ 220 hours = R$ 13.64 per normal hour
50% additional
For overtime with 50% additional:
Formula: Normal hourly rate × 1.50 = 50% overtime hourly rate
Example: R$ 13.64 × 1.50 = R$ 20.46 per overtime hour with 50% additional
100% additional
For overtime with 100% additional (Sundays and holidays):
Formula: Normal hourly rate × 2.00 = 100% overtime hourly rate
Example: R$ 13.64 × 2.00 = R$ 27.28 per overtime hour with 100% additional

Practical calculation examples
50% overtime
Situation: Employee with R$ 2,800 salary, worked 15 overtime hours in the month.
Calculation:
- Normal hourly rate: R$ 2,800 ÷ 220 = R$ 12.73
- 50% overtime rate: R$ 12.73 × 1.50 = R$ 19.09
- Total overtime: 15 × R$ 19.09 = R$ 286.35
100% overtime
Situation: Same employee worked 4 overtime hours on Sundays.
Calculation:
- 100% overtime rate: R$ 12.73 × 2.00 = R$ 25.46
- Total: 4 × R$ 25.46 = R$ 101.84
Final salary: R$ 2,800 + R$ 286.35 + R$ 101.84 = R$ 3,188.19

Impact on 13th salary
Overtime hours are included in the calculation of the 13th salary:
- Add up the average overtime from the last 12 months
- Divide by 12 to find the monthly average
- Apply this average to the 13th salary
Impact on vacation pay
Overtime hours also affect vacation pay:
- Integrated into the constitutional third calculation (1/3 over vacation)
- Average overtime from the last 12 months
- Value is added to vacation + 1/3
Example: Monthly average of R$ 300 in overtime = R$ 400 more in vacation pay (R$ 300 + R$ 100 third)
