The night hour is shorter: 52 minutes and 30 seconds (CLT art. 73, § 1). So 7 clock hours between 10 pm and 5 am count as 8 hours, and the 20% premium applies to all 8.
An estimate before INSS and income tax. Union agreements may set higher premiums, other divisors or hour banks.
Frequently asked questions
How is overtime calculated in Brazil?
Divide the monthly salary by the divisor (220 for a 44-hour week, from CLT art. 64) to get the normal hour, then add at least 50% (CLT art. 59, § 1). On R$ 2,200 the hour is R$ 10 and each overtime hour R$ 15.
When is overtime paid at 100%?
Work on Sundays or public holidays with no other day off in return is paid double (Law 605/1949, art. 9, and TST Súmula 146). Union agreements often set higher rates for other cases too.
How does the night premium work?
Urban work between 10 pm and 5 am is paid at least 20% more, and the night hour counts as 52 minutes and 30 seconds (CLT art. 73). Seven clock hours become eight paid night hours. Rural workers follow Law 5.889/1973.
What is the DSR reflex on overtime?
Habitual overtime also raises the paid weekly rest (Law 605/1949, art. 7, and TST Súmula 172). The usual formula is overtime of the month divided by working days, times the Sundays and holidays of the month.
Should I use 220, 200 or 180 as the divisor?
Use 220 for 44 hours a week, 200 for 40 hours (TST Súmula 431) and 180 for 36 hours, the 6-hour day. The divisor comes from CLT art. 64: salary divided by 30 times the daily hours.
Is there a limit on overtime?
Yes. The CLT allows up to 2 extra hours a day, by individual or collective agreement (art. 59). Hours compensated through an hour bank within the legal limits are not paid as overtime.
