Sunday premium calculator
Short answer
Enter the daily salary and how many Sundays the person worked. The premium is 25% of one day's salary for each Sunday.
How to do the math by hand
With $400 per day, the premium for one Sunday is 400 × 25% = $100. If the person worked all four Sundays of the month, it is $400.
Legal basis
Article 71 of the Federal Labor Law.
Why everything starts with the working-time record
Almost every labor calculation starts from the same data point: how many hours and which days each person worked. If that data is uncertain, so is everything else.
- Overtime: it is paid according to the hours of each week.
- Sunday premium and rest days worked: they depend on which days were worked.
- Aguinaldo and profit sharing: they use the days worked in the year.
- Labor lawsuits: the company must prove the working time.
Since 2026, the Federal Labor Law requires that record to be electronic, per person, with start and end time.
Common mistakes
- Entering net pay instead of gross.
- Not changing the shift type when it is a night or mixed shift.
- Treating the result as if it were the payslip.
- Forgetting that the UMA and the minimum wage change every year.
- Not noting what data the calculation was made with.
What to do now
- Confirm the current value for the year.
- Have each person's daily salary at hand.
- Check the days and hours worked in your record.
- Do the math and keep it.
- Validate it with your accountant.
