Work out the night premium with the reduced night hour: 52 min 30 s count as an hour, so 7 hours on the clock pay as 8.
Night work in Brazil is paid twice over, and the second part is the one calculators keep missing. The first is the premium: 20% above the ordinary hour for urban workers, on time worked between 22:00 and 05:00. The second is the reduced night hour of CLT article 73, §1 — in that window an hour of work lasts 52 minutes and 30 seconds, not 60. Seven hours on the clock are therefore eight night hours, and the premium is owed on the eight. Skip the reduction and the result comes out roughly 14% short, which is what happens on most sites that take your salary and your hours and hand back a number.
So this page prints both counts and the steps between them: clock minutes divided by 52.5 gives night hours, salary divided by the monthly hours base gives the ordinary hourly rate, and the premium is the rate times the percentage times the night hours. A second rule lives in the same window. If the whole night period was worked and the shift carried on past 05:00, the extension is paid with the premium too — TST Súmula 60, II. Enter a shift from 20:00 to 06:00 and the hour after five is counted, with a box to switch it off if your case is different.
The reduced hour has a consequence people meet on the payslip without understanding it: eight hours on the clock inside the window come to 9 hours and 9 minutes of night time, so the working day ends before the shift does and the excess is normally overtime on top of the premium. Two limits: these are the urban rules, since rural work runs on 25%, its own windows and no reduction at all; and habitual night work also raises holiday pay, the 13th salary and the FGTS deposit, not calculated here. Everything runs in your browser, and each legal value sits in the table with its year and an edit field.
Night hours = clock minutes worked inside the night window ÷ 52.5. Hourly rate = gross monthly salary ÷ monthly hours base. Night premium = hourly rate × premium percentage × night hours. Amounts are held as whole cents and the rounding happens once, at the end.
Almost certainly the reduced night hour. Between 22:00 and 05:00 a worked hour lasts 52 minutes and 30 seconds, so seven hours on the clock are eight night hours, and the premium is paid on the night hours. The tool shows both counts and the difference in money.
For urban workers, 22:00 to 05:00, with a premium of at least 20%. Both the window and the percentage are editable in the table: an agreement can raise the premium, and rural work uses other windows — 21:00 to 05:00 in farming, 20:00 to 04:00 in livestock — with 25% and no reduced hour.
The hours before 22:00 are ordinary. The hours after 05:00 keep the premium when the whole night period was worked, under TST Súmula 60, II — the calculator applies that and says so in the result. Untick the box if the extension does not apply to you.
It can. Eight hours on the clock inside the window come to 9 hours and 9 minutes of night time, past the eight-hour day. The excess is normally overtime, paid on top of the premium. This page flags it; use the overtime calculator to price those hours.
The page assumes it will. The year and the review date sit above the table, every value — premium, length of the night hour, start and end of the window, minimum wage — is editable, and "Restore official values" brings the originals back.
