About this tool
Under Brazilian labour law (CLT) each overtime hour is paid at least 50% above the normal hour, and 100% on Sundays and holidays that were not compensated. The normal hour is the monthly salary divided by the divisor of the contract: 220 for 44 hours a week, 200 for 40, 180 for 36 and 150 for 30. Night work (10 pm to 5 am) earns a 20% premium, and each night hour lasts only 52 minutes and 30 seconds, so 7 hours on the clock count as 8. Overtime done regularly also raises the paid weekly rest (DSR), calculated by dividing the month's overtime by the working days and multiplying by the Sundays and holidays. The calculator adds it all up and shows how much is actually left after INSS and income tax with the 2026 tables. Everything is calculated in your browser.

Frequently asked questions
How do I calculate the overtime hour value?
Divide the monthly salary by the divisor (220 for 44 hours a week) and multiply by 1.5. With a salary of R$ 2,200 the hour is R$ 10 and the overtime hour R$ 15.
When is overtime paid at 100%?
On Sundays and holidays worked without a day off in compensation (Lei 605/49 and Súmula 146 of the TST). Some collective agreements also set 100% after a number of hours.
What is DSR on overtime?
The paid weekly rest also grows with regular overtime (Súmula 172 TST): total overtime of the month ÷ working days × Sundays and holidays.
How many overtime hours are allowed?
Up to 2 extra hours a day (CLT art. 59). Beyond that only in emergencies or by specific agreement.
Does overtime pay INSS and income tax?
Yes. It is added to the month's salary, so INSS and income tax are calculated on the total. That is why the calculator shows the net gain, which is lower than the gross overtime.
Does overtime count in the 13th salary and vacation?
Yes, when it is regular: the average of the overtime goes into the 13th salary, vacation pay with the one-third bonus, notice pay and the FGTS deposit.
