Frequently Asked Questions

How is overtime calculated?
The standard workday is 8 hours. Any hours beyond that are considered overtime, typically paid at 1.5x the regular rate. On weekends and holidays, overtime may be paid at 2x. Use the "Daily Shift" mode to calculate automatically.
What is the difference between HH:MM and decimal format?
HH:MM shows hours and minutes (e.g., 7:30 = seven hours thirty minutes). Decimal converts minutes to a fraction of an hour (e.g., 7.50 = seven and a half hours). The decimal format is commonly used in payroll systems for salary calculations.
How does the night shift premium work in Brazil?
Under Brazilian labor law (CLT), the night shift premium is 20% extra pay, and a night hour equals 52 minutes and 30 seconds (not 60). Night shifts run from 10 PM to 5 AM in urban areas. This means 7 clock-hours = 8 paid hours. For salary calculations, use our Net Salary Calculator.
