Night Work Pay Calculator

How much is an hour of night work worth in Portugal? By law, work performed in the night period is paid with a 25% uplift over equivalent day work. This calculator starts from your monthly salary, computes the official hourly value and shows what a night hour pays, how much extra you earn in the month and what that adds up to over a year.

Enter your monthly gross salary, weekly schedule and the hours worked in the night period (between 22h and 7h, absent a specific rule). The legal uplift is 25%; adjust it if your collective agreement sets a different value.

Night uplift in the month
€86.54
For 60 night hours
Value of one night hour
€7.21
Normal hour: €5.77
Base hourly value (art. 271)€5.77
Uplift per hour (25%)+€1.44
Night hour€7.21
The same 60 hours by day€346.15
Uplift in the month+€86.54
Total pay for the night hours (month)€432.69
Uplift over a year (12 equal months)€1,038.46

Absent a specific collective-agreement rule, the night period runs from 22h on one day to 7h on the next (article 223 of the Labour Code).

Gross values: the night uplift pays income tax and Social Security like the rest of the salary.

Estimate for normal hours worked in the night period, applying the article 266 uplift of the Labour Code to the article 271 hourly value. It does not cover overtime (which has its own uplifts) or a collective-agreement shift allowance.

Educational estimate, not advice. The 25% uplift is the general legal minimum, subject to the legal exceptions; your collective agreement may set its own rules. Always check your payslip.

What counts as night work

Night work is work performed in a period of at least 7 and at most 11 hours that includes the interval between 0h and 5h (article 223 of the Portuguese Labour Code). That period can be set by a collective agreement; absent a specific rule, the legal default applies: between 22h on one day and 7h on the next. Hours worked inside that window are night hours.

The legal uplift is 25%

Night work is paid with a 25% uplift over the pay of equivalent work performed during the day (article 266(1)). That is the general legal minimum: the collective-bargaining instrument (IRCT) of your sector may set a different value, or replace the uplift with a working-time reduction or a fixed increase of the base salary. That is why the percentage is editable in the calculator.

How the hourly value is calculated

The base is the official hourly value of article 271: (monthly salary × 12) ÷ (52 × weekly hours). With €1,000 a month and 40 hours a week, one hour is worth €5.77. A night hour is worth that plus 25%: €7.21. The calculator uses exactly this formula, the same one as the hourly-rate calculator.

Not everyone is entitled to the uplift

Unless the collective agreement says otherwise, the uplift is not due in activities carried out exclusively or predominantly at night (shows and public entertainment, for example), in activities that by their nature must run at night, or when the pay was already set taking night work into account (article 266(3)). If you are in one of these situations, your contract or collective agreement determines what you receive.

Shifts and the shift allowance are a different thing

Rotating-shift workers only receive the night uplift for the hours that fall inside the night period. The "subsídio de turno" (shift allowance) many companies pay is not required by general law: it exists only where the collective agreement or the contract creates it, at the value set there. The calculator computes the legal uplift on night hours; a shift allowance, where it exists, is paid on top.

The uplift pays income tax and Social Security

The night uplift is ordinary employment pay: it enters income tax (IRS), at your rate, and pays the 11% employee Social Security like the rest of the salary. The figures in this calculator are gross; to see the net effect, use the net-salary calculator.

Worked example

Imagine a €1,000 monthly salary, 40 hours a week and 60 night hours in a month. The hourly value is (1,000 × 12) ÷ (52 × 40) = €5.77. The 25% uplift is worth €1.44 per hour, so a night hour pays €7.21. The 60 night hours earn €432.69, that is, €86.54 more than the same hours during the day. Over a year at the same hours, the uplift adds up to €1,038.46 gross.

Frequently asked questions

What is night work in Portugal?
It is work performed in a period of at least 7 and at most 11 hours that includes the interval between 0h and 5h (article 223 of the Labour Code). The exact period can be set by a collective agreement; absent one, the legal default applies: between 22h on one day and 7h on the next.
How much more do you earn for working at night?
The general rule is a 25% uplift over the pay of equivalent day work (article 266(1) of the Labour Code). With an hourly value of €5.77, a night hour pays €7.21. The collective agreement of the sector may set a different value or replace the uplift with a working-time reduction or a fixed salary increase.
How is the night hourly rate calculated?
First compute the official hourly value: (monthly salary × 12) ÷ (52 × weekly hours), from article 271. Then add the 25% uplift. With €1,000 a month and 40 weekly hours: normal hour €5.77, night hour €5.77 × 1.25 = €7.21.
Does everyone who works at night get the 25%?
No. Unless the collective agreement says otherwise, the uplift is not due in activities carried out exclusively or predominantly at night (shows and public entertainment, for example), in activities that must by nature run at night, or when the salary was already set taking the night schedule into account (article 266(3)).
Is the shift allowance mandatory?
It is not required by general law. The shift allowance exists only where the collective agreement or the employment contract provides for it, at the value defined there. What the law guarantees everyone is the 25% uplift for hours actually worked in the night period, subject to the article 266 exceptions.
Does the night uplift pay taxes?
Yes. The uplift is ordinary employment income (category A): it pays income tax at your rate and the 11% employee Social Security, like the rest of the salary. It does not benefit from the reduced withholding that applies to overtime; that rule is specific to trabalho suplementar.
Are night work and overtime the same thing?
No. Night work is the normal hours of your schedule that fall in the night period, paid with the 25% uplift. Overtime (trabalho suplementar) is hours beyond your schedule, with its own uplifts of 25% to 50% (doubled above 100 hours a year). An overtime hour worked at night accumulates both regimes; this calculator handles normal night hours only.
