Portugal Overtime & Night Work Pay Calculator
Enter your base salary and the extra hours you worked, and see what they're worth -- with the legal supplements for a working day, a rest day or holiday, and night work.
How we calculated this
Hourly rate = (monthly salary × 12) ÷ (52 × weekly hours). Up to 100 annual overtime hours: +25% on the first working-day hour, +37.5% on subsequent ones, +50% on a rest day or holiday. Above 100 hours: +50%, +75% and +100% respectively. Night work always adds +25%, independent of the annual limit.
How the hourly rate is calculated
The Código do Trabalho defines its own formula for the normal hourly rate, used as the base for every supplement: the monthly salary multiplied by 12 (to annualise it) and divided by 52 weeks times your normal weekly hours. It isn't simply the salary divided by the month's hours -- this formula uses the whole year as its reference.
The two tiers of overtime
Within the first 100 overtime hours of the calendar year, the first hour (or fraction) worked extra on a working day has a 25% supplement, and every subsequent hour that same day has 37.5%. On a mandatory rest day or public holiday, the supplement is always 50% per hour, with no distinction between the first and later hours. Once the 100 annual hours are exceeded, these figures rise to 50%, 75% and 100% respectively -- a legal incentive against normalising too much overtime across the year.
The night work supplement
Working during the night period (the exact window is defined by law or a CCT, typically between 10pm and 7am) entitles you to a flat 25% supplement over the equivalent daytime value -- regardless of whether you're a shift worker, and regardless of whether those hours are also overtime or part of your normal schedule. This supplement doesn't apply to activities that are inherently nocturnal by nature, like bars or nightclubs.
When a collective agreement changes everything
These are the figures the law sets by default, in the absence of a collective bargaining agreement (CCT) of your own. Many sectors negotiate different terms -- sometimes more favourable, sometimes with alternative mechanisms like a time bank or time off in lieu instead of payment. Always check your CCT before treating these figures as final for your situation.
What this calculator doesn't do
It doesn't model specific collective agreements, time banks, or the IRS withholding that applies to overtime (which has its own rules, different from regular salary). The result is always the gross amount due, before tax and Social Security.
Frequently asked questions
Can my collective agreement set different figures?
Yes -- the supplements here are the Código do Trabalho's own, which apply when there's no collective bargaining agreement (CCT) that says otherwise. Many sectors have their own agreements, sometimes more favourable. Always check your CCT before treating these figures as final.
What counts toward the 100-annual-hours limit?
The total overtime hours worked over the calendar year, which accumulates progressively. Once it's exceeded, the supplements rise to the higher figures (50%/75% on a working day, 100% on a rest day or holiday).
Does overtime get different tax treatment for IRS?
Yes, overtime has its own separate withholding and a reduced rate compared with regular income, within certain limits -- but that's a matter of IRS withholding, not the gross amount calculated here, which is simply the amount due before tax.
